The Impact of Climate Change on Work – Published on Labor Day September 2, 2024

I  am not able to comment inside of the posted pages since they are images but here is a short summary of the key points.

  • Reductions in the  Demand for Labor
  • Reductions in the Demand for Labor due to Weather  Extremes.
  • Worker Absentism.
  • Declines in Productivity (heat is a major factor)
  • Impact on the self-employed.
  • Reallocation of Labor

It is a thorough report on the possible impacts but a bit short on data as to what the impacts have been but there is quite a bit of data in the report it is just not complete. It is a very interesting report to read on  Labor Day.

…Areas of heavy rain and the potential for flash flooding forecast
throughout the south-central U.S. over the next couple of days…

…Well above average, hot late-Summer temperatures spread from the
northwestern to north-central U.S. through Tuesday…

…Critical Fire Weather for parts of the central Great Basin on Monday…

Areas showers and thunderstorms will continue over the south-central U.S.
the next couple of days with locally heavy rainfall expected. First, a
cold front pushing into Texas this morning (Monday) will slow and become
quasi-stationary by later tonight as an upper-level disturbance passes
overhead, combining to help trigger numerous storms north of the boundary
over the Texas Hill country, west Texas, and the Big Bend region. There is
a Slight Risk of Excessive Rainfall (level 2/4) as continued storm
development and heavy downpours may lead to some scattered flash flooding.
A more localized threat over the Texas Hill country exists Tuesday, with a
Slight Risk in place. Additional storms are expected to the east
associated with an area of low pressure located just off the Texas coast.
Another Slight Risk of Excessive rainfall has been introduced for today
along the central Texas Gulf Coast where more heavy downpours and some
scattered flash flooding will be possible. The widespread storms,
rainfall, and clouds throughout the region will keep temperatures well
below average, with many highs in the 70s across central and west Texas,
and 80s further east towards the Gulf Coast.

Some thunderstorms are also expected today ahead of this front further
east along the coastal Carolinas southwest through Georgia towards the
central Gulf Coast, with the focus shifting to the central Gulf Coast by
Tuesday as the boundary slows and becomes quasi-stationary. Daily
thunderstorm chances will continue for the Florida Peninsula as well. To
the north, the passage of the cold front means some cooler temperatures
for much of the eastern U.S. the next couple of days. Forecast highs range
from the 60s and 70s for the Upper Midwest, Great Lakes, and interior
Northeast; the 70s to low 80s from southern New England west through the
Mid-Atlantic and into the Ohio and Middle Mississippi Valleys; and 80s
from the Carolinas west through the Tennessee Valley. A taste of Fall is
in store for many in the interior Northeast Tuesday morning as lows drop
into the 40s. Highs will remain a bit warmer to the south, with 90s for
the Lower Mississippi Valley and along the Gulf Coast.

Much above average, hot late-Summer temperatures seen over the
northwestern U.S. this weekend will spread into the northern High Plains
today as a strong upper-level ridge over the West shifts eastward.
Forecast highs are mainly in the 90s, with some upper 90s possible for the
northern High Plains. An approaching Pacific system/associated surface
cold front will help to bring some relief to the northwestern U.S. on
Tuesday as highs drop into the 80s. In addition, the heat combined with
dry conditions and increasing winds ahead of the approaching Pacific
system have prompted a Critical Risk of Fire Weather from the Storm
Prediction Center for much of the central Great Basin today. Another
Critical Risk also exists over the Black Hills of South Dakota and
northwestern Nebraska given a similar setup with dry conditions and
increasing winds as a trough develops in the lee of the Rockies. Some very
isolated showers and storms today over the Great Basin will become a bit
more numerous into the northern Rockies on Tuesday as the frontal system
pushes eastward. Increasing moisture may lead to some locally heavy
rainfall and an isolated instance or two of flash flooding. Conditions
will generally be dry and at or above average temperature-wise elsewhere
in the West the next couple of days, with highs in the 90s for the central
Great Basin and interior central California and 100s in the Desert
Southwest. Some cooler temperatures over northern California into the
Pacific Northwest today will begin to rebound on Tuesday as another ridge
begins to build along the West Coast in the wake of the passing Pacific
system.

EIA August Monthly Energy Report – Published on September 1, 2024

The EIA Monthly  Energy Review is long and does not change much from month to month since a lot of the information is historical.  Here I present the graphics from just the first three chapters. It is enough to see that coal is being phased out, electricity is increasingly important and our incorporation of alternative sources of energy is slow.  I  may provide more information in a future article but this should be enough for people to decide if they want more detail on the rest of the report.

At the end of the article, I provided a link to the full Monthly Review. The EIA Monthly Energy Review is separate from its annual reporting on crude oil and natural gas reserves. My prior article on their estimates of reserves can be accessed HERE.  I think that reserves are only updated once a year.

…Areas of heavy rain with the potential for flash flooding across the
south-central U.S. through Labor Day…

…Unsettled weather across much of the East continues today…

…Well above average, hot late-summer temperatures spread from the
northwestern to north-central U.S. this holiday weekend…

Areas of locally heavy rainfall will continue over portions of the
south-central U.S. through the holiday weekend as a couple disturbances
help to drive shower and thunderstorm chances. First, a lingering coastal
low will bring more storms to the western Louisiana and upper Texas Gulf
Coasts today (Sunday) with a Marginal Risk of Excessive Rainfall (level
1/4) and some isolated flash flooding. The low will drift southwestward
Monday (Labor Day), bringing storm chances to the central Texas Gulf
Coast. Meanwhile, additional storms are expected along and to the north of
a lingering frontal boundary draped from north Texas southwest towards the
Rio Grande, with another Marginal Risk area Sunday across southeastern New
Mexico and central/western Texas. An embedded weakness in broader
upper-level ridging aloft will help to encourage more widespread storms on
Monday with a higher threat of heavy rainfall and scattered flash
flooding, especially as soils become wetter given rainfall over the first
part of the weekend. A Slight Risk of Excessive Rainfall (level 2/4) has
been introduced for the Texas Hill Country where this threat is greatest,
with a continued more expansive Marginal Risk across southeastern New
Mexico and Texas. The widespread storms and clouds will keep temperatures
below average through the weekend in the region, with highs generally in
the 80s, and even some 70s on Monday for west Texas and eastern New
Mexico.

Showers and storms will also remain in the forecast for much of the
eastern U.S. ahead of a lingering frontal boundary. The heaviest rainfall
is expected today from the southern Mid-Atlantic/Carolinas west through
the southern Appalachians where some isolated flash flooding will be
possible. Locally heavy rainfall will also be possible west through the
Tennessee Valley and into the Mid-South. More scattered, lighter showers
are expected across the Northeast. A second, stronger cold front will
bring drier air by Monday for most locations, though storms are expected
to continue ahead of the front along the Carolina coasts southwest through
Georgia towards the central Gulf Coast. Daily thunderstorms are also
forecast for the Florida Peninsula. Forecast highs today range from the
70s in New England and the Great Lakes/Upper Mid-West to the 80s in the
Mid-Atlantic and Ohio/Tennessee/Middle Mississippi Valleys and 90s deeper
into the Southeast and Lower Mississippi Valley. The passing cold front
will bring the more mild temperatures in the 70s further into the northern
Mid-Atlantic and Ohio/Middle Mississippi Valleys Monday.

An upper-level ridge will continue to bring well above average, hot
late-Summer temperatures to the northwestern U.S. today as highs soar into
the 80s to near 90 for the Pacific Northwest and mid- to upper 90s for the
northern Great Basin. Heat Advisories remain in place for portions of the
northern Great Basin given the higher threat for heat-related impacts. The
ridge will shift eastward on Monday, bringing these hotter temperatures
into the northern High Plains with forecast highs in the mid- to upper
90s. Those with plans this weekend should limit their time outdoors or
seek more breaks from the sun in the shade, as well as remember to stay
well hydrated. An upper-level low over the Pacific approaching in its wake
will bring relief to the Pacific Northwest Monday as highs drop into the
70s, and conditions will return closer to average for the northern Great
Basin with highs in the mid-80s to lower 90s. However, strengthening
downsloping winds off the northern Sierra Nevada with the approach of the
upper low on Monday have prompted a Critical Risk of Fire Weather from the
Storm Prediction Center for northeastern California, southeastern Oregon,
and northwestern Nevada. Elsewhere in the West, highs will be closer to
average but still hot, with highs in the 90s for the Great Basin and
interior central California, and 100s for the Desert Southwest. Conditions
will be a bit cooler in the Four Corners region with highs in the 80s, and
a few thunderstorms will be possible today.

NOAA Updates their Mid-Month Forecast for September 2024 on September 1, 2024 and this article was posted as described below.

It is now updated.  I will be adding comments for a little while but the images are now updated.

At the end of every month, NOAA updates its Outlook for the following month which in this case is August of 2024. We are reporting on that tonight.

There have been some significant changes in the Outlook for  September and these are addressed in the NOAA Discussion so it is well worth reading.  We provided the prior Mid-Month Outlook for September for comparison. It is easy to see the substantial changes in the weather outlook by comparing the Mid-Month and Updated Maps.

The article includes the Drought Outlook for September. NOAA also adjusted the previously issued Seasonal (SON) Drought Outlook to reflect the changes in the September Drought Outlook. We also provide the Week 2/3 Tropical Outlook for the World.

The best way to understand the updated outlook for September is to view the maps and read the NOAA discussion. I have highlighted the key statements in the NOAA Discussion.

I am going to start with graphics that show the updated Outlook for September and the Mid-Month Outlook for September. This is followed by a graphic that shows both the Updated Outlook for September and the previously issued three-month outlook for SON 2024. So you get the full picture in three graphics.

Here is the updated Outlook for September 2024.

 

For Comparison Purposes, Here is the earlier Mid-Month Outlook for September.

 

It is important to remember that the maps show deviations from the current definition of normal which is the period 1991 through 2020.  So this is not a forecast of the absolute value of temperature or precipitation but the change from what is defined as normal or to use the technical term climatology.

It is a substantial change from what was issued on August 15, 2024. Remember, it is the first set of maps that are the current outlook for September.  One expects some changes  16 days later. However, the changes to the updated September Outlook are very significant.  This then gives us some reason to question the (August 15, 2024) three-month SON temperature and precipitation Outlooks which are shown in the following graphic.

NOAA provided a combination of the Updated Outlook for September and the Three-Month Outlook.

The top pair of maps are again the Updated Outlook for the new month. There is a temperature map and a precipitation map. The bottom row shows the three-month outlooks which includes August the new month. I think the outlook maps are self-explanatory.

To the extent that one can rely on a forecast, we would conclude that October and November will be very different than September, especially for precipitation. You can subtract September from the three-month Outlook and divide by two to get a combined October-November Outlook.

However given the major change in the new September outlook from what was issued on August 15,  2024, we might not trust the Seasonal Outlook issued on August 15, 2024. Something to think about. But the major factor is the projected slower onset of La Nina. Thus this change is consistent with the pattern the NOAA has been predicting although they have been playing catch-up.

I am still not convinced that there will be a La Nina Winter.

Some readers may need to click “Read More” to read the rest of the article.  Some will feel that they have enough information. But there is a lot more information in the rest of this article.

…Widespread showers and storms expected from the Southern Plains to East
Coast to start the holiday weekend…

…Flash flooding and severe weather possible for portions of the
northern/central Appalachians Saturday…

…Multiple days of heavy rain may cause flash flooding for portions of
the Louisiana and Texas Gulf Coasts…

…Well above average, hot late-Summer temperatures forecast in the
northwestern U.S. this weekend…

An upper-level trough and associated surface cold front will progress
eastward this morning (Saturday), extending from the Northeast southwest
through the Ohio/Tennessee Valleys, Middle Mississippi Valley/Mid-South,
and into the Southern Plains. Another round of showers and thunderstorms
is expected along and ahead of the length of the front, with moist air and
instability likely leading to some more intense thunderstorms, heavy
downpours, and the potential for isolated flash flooding. A locally higher
threat is expected across portions of the northern/central Appalachians
given the potential for some training/repeated rounds of storms across
more sensitive mountain terrain. The region is under a Slight Risk of
Excessive Rainfall (level 2/4) for the threat of a few more scattered
instances of flash flooding. In addition, stronger winds aloft with the
passing upper trough will bring increased shear for some more organized
storms. The Storm Prediction Center has also included a Slight Risk of
severe weather (level 2/5), mainly for the threat of some damaging winds.
The fronts forward progression will slow through Saturday, especially with
southwestward extent, leading to additional rounds of storms on Sunday
with moderate to locally heavy rainfall from the southern
Mid-Atlantic/Carolinas west through the Tennessee Valley, Mid-South, and
into the Southern Plains. Some isolated flash flooding will remain
possible, especially for the southern Appalachians/Mid-Atlantic and
Carolinas as well as the southern High Plains. A secondary cold front
sweeping in from the north will bring an end to precipitation chances for
most areas outside of the Southeast/Southern Plains later Sunday night.

Further south, another area of storms is expected to continue today in
vicinity of a coastal low near the western Louisiana and upper Texas Gulf
Coasts. Another Slight Risk of Excessive Rainfall is in place as slow
moving and very heavy rainfall-producing storms given abundant Gulf
moisture may lead to some additional scattered instances of flash
flooding, especially given wetter antecedent conditions from rainfall the
past few days. At least an isolated threat for flash flooding will exist
into Sunday, though rainfall amounts may trend downward. Daily
thunderstorms are also forecast for the Florida Peninsula, with some
isolated instances of urban flooding possible for South Florida today.
Temperature-wise, relief from the more intense heat this past week will
finally come to the Middle Mississippi, Ohio, and Tennessee Valleys as
increasing storm chances and the approaching front keep temperatures down
a bit, with highs generally in the 80s and low 90s. Low 90s will also be
common across the Southeast with mid-80s to low 90s for the Appalachians
and southern Mid-Atlantic. Highs will remain cooler and mainly in the 70s
to the north of a warm front for the northern Mid-Atlantic and New England
Saturday, with a rebound into the low 80s expected for many locations
Sunday as the warm front lifts north. The Northern/Central Plains and
Midwest will see highs in the 80s today before a cold front brings cooler
temperatures in the 70s Sunday. Conditions will remain much below average
for late Summer over the Lower Mississippi Valley and Southern Plains,
with highs generally in the mid-80s outside of south Texas. Some 70s will
be possible for west Texas.

Well above average, hot late-Summer temperatures will continue into the
weekend for the northwestern U.S. as a broad upper-level ridge remains in
place over the West. Highs are forecast into the 90s to near 100 across
the interior Pacific Northwest, northern Great Basin, and northern
Rockies, and have prompted some Heat Advisories for the northern Great
Basin/Rockies given the heightened risk of heat-related illness. Those
with outdoor plans for the holiday weekend should remember to take more
frequent breaks from the heat in the shade and stay hydrated. Highs
elsewhere across the West will not be quite as above average, but still
hot, with 90s for the Great Basin and interior California and 100s in the
Desert Southwest. Portions of the Southwest/Four Corners Region will be a
bit cooler with shower and thunderstorm chances expected in vicinity of a
lingering frontal boundary, with highs in the upper 70s and 80s.

…Widespread shower and thunderstorm chances from the Plains to East
Coast to start the holiday weekend, producing heavy rain and severe
weather...

…Heavy rain and scattered flash flooding possible along the Louisiana
and upper Texas Gulf Coasts…

…Record heat continues across the Ohio/Tennessee Valleys into the
Southern Appalachians today with relief on tap for the weekend…

…Much above average temperatures build across the Pacific Northwest,
northern Great Basin and into the northern Rockies…

A broad area of showers and thunderstorms is expected over central and
eastern portions of the country heading into the first half of the holiday
weekend ahead of an approaching cold front. Today (Friday), storm chances
will stretch from the Lower Great Lakes southwest through the Middle
Mississippi Valley and into the Southern Plains/Rockies. Plentiful
moisture and instability ahead of the front will lead to some more robust
thunderstorms and locally heavy rainfall, with some isolated flash
flooding possible. In addition, an accompanying upper-level trough
overhead will bring some higher winds over the Great Lakes, leading to
stronger shear and the potential for some severe weather. There is a
targeted Slight Risk (level 2/5) from the Storm Prediction Center over
portions of eastern Michigan mainly for the risk of damaging winds. On
Saturday, the front will progress further south and eastward into the Ohio
Valley and Northeast while slowing in progress and becoming nearly
stationary with southwestward extent into the Southern Plains. A broader
area of severe weather is expected over portions of the northern/central
Appalachians and Mid-Atlantic as the upper-level trough digs southward
over the region. Damaging winds will once again be the primary threat. In
addition, isolated flash flooding will remain possible, with the potential
that a higher threat may materialize given the slowing frontal
progression.

Further south, another more concentrated area of heavier rainfall is
expected to continue along portions of the western Louisiana and upper
Texas Gulf Coasts as an area of low pressure lingers in the vicinity.
Higher rain rates and repeated rounds of storms may lead to locally higher
rain totals of 2-4″+ over Friday and Saturday. A Slight Risk of Excessive
Rainfall (level 2/4) has been included for both days for the potential of
some scattered flash flooding. Daily thunderstorms are also forecast over
the central/southern Florida Peninsula.

One more day of excessive heat is forecast over the Ohio/Tennessee Valleys
and southern Appalachians today as temperatures soar once again into the
mid- to upper 90s. High humidity may bring head indices into the low 100s.
A few record-tying/breaking highs will also be possible. The approaching
cold front and increasing storm chances/cloud cover will finally bring
some relief on Saturday as highs drop into the 80s across the Middle
Mississippi and Lower Ohio Valleys, with upper 80s to low 90s for the
Upper Ohio and Tennessee Valleys. Elsewhere, highs will be particularly
mild north of the frontal boundary across the northern Mid-Atlantic and
New England, with 70s and even some upper 60s expected today. Temperatures
will warm up a few degrees as the boundary lifts northward as a warm front
on Saturday. Conditions will also be well below average over portions of
the Southern Plains to the northwest of the frontal boundary, with low to
mid-80s forecast. Areas ahead of the front from Texas into the Southeast
and the southern Mid-Atlantic will generally be in the upper 80s to low
90s.

In the wake of the departing trough to the east, an upper-level ridge over
the Pacific Coast will shift inland, helping to focus hot, much above
average temperatures over the northern tier of the West. Forecast highs on
Friday for the northern Great Basin and Pacific Northwest will range
between the low to mid-90s for most locations. Then, on Saturday, the heat
will intensify as well as expand into the northern Rockies, with many
highs in the mid- to upper 90s, 10-20 degrees above average. Heat
Advisories have been issued for much of the northern Great Basin given the
heightened risk of heat-related illnesses, and extra care should be taken
to seek shaded areas and remain hydrated this holiday weekend. Elsewhere
in the West, temperatures will generally be near or just above average,
with 60s and 70s along the coast, 80s to low 90s for the Great Basin,
mid-90s for the central California Valleys, and 100s in the Desert
Southwest. A few showers and thunderstorms will be possible along a
lingering frontal boundary through the central/southern Rockies and into
the Southwest.

…Above average heat expected to linger across the Ohio and Tennessee
Valleys through Friday before a cooling trend arrives by the weekend…

…Strong to severe thunderstorms expected across the upper Midwest and
Mid-Atlantic today, then across the Great Lakes on Friday…

…Some tropical heavy rain and thunderstorms could affect the western
Gulf Coast region through the next couple of days…

A vigorous low pressure system currently centered near the U.S.-Canadian
border of the High Plains will move steadily across southern Canada
through the next couple of days. Strong to severe thunderstorms forming
ahead of a potent cold front trailing south from the low pressure center
will likely impact North Dakota early this morning, before quickly
advancing into Minnesota and down across the central Plains into this
evening. These thunderstorms could develop into supercells that may
contain damaging winds, large hail, and a few tornadoes. Meanwhile,
thunderstorms across the Mid-Atlantic could also be strong to severe where
some gusty winds and heavy rain may lead to isolated to scattered
instances of flash flooding by this evening and into the overnight. The
front that helps trigger these thunderstorms will gradually edge farther
southward into the Mid-Atlantic on Friday, bringing relief from the heat
with high temperatures only reaching into the 70s for much of the
Northeast. The cool air will not have a chance to reach into the Ohio and
Tennessee Valleys though as southerly flow increases ahead of the deep low
pressure system in southern Canada. A couple more days of heat with
afternoon high temperatures well up into the 90s are expected in these
areas. Above average overnight low temperatures will provide little
relief, lows will likely stay in the 70s for much of the region. A
cooling trend will set in by the weekend behind the cold front. Scattered
thunderstorms with embedded strong to severe storms will then extend
southwestward across the Midwest into the central Plains on Friday as the
trailing end of the front begins to slow down and become nearly stationary
into the southern Plains by Saturday.

Separate from the frontal system across the northern tier of the country,
tropical moisture from the Gulf of Mexico could lead to heavy rain across
portions of the western Gulf Coast region as an upper-level low lingers
over Texas. A small scale low pressure center could form and interact
with a subtle coastal front to enhance rainfall rates, leading to the
potential for flooding issues over portions of the the western Gulf Coast
through the next couple of days.

Across the rest of the country, a general cooldown is expected behind the
cold front across the north-central U.S. and high temperatures should be
generally in the middle 80s. Much of the Southeast should be warm and
humid with commonplace high temperatures in the middle 90s. A warming
trend is expected for the western U.S. following the recent cool spell as
the strong low departs into southern Canada.

…Record heat for the Mid-Atlantic today but the heat will last a couple
more days for the Ohio and Tennessee Valleys into the interior Southeast…

…Active thunderstorms will bring the threats of heavy rain, flash
flooding and severe weather across the northern Plains tonight and then
the upper Midwest Thursday through early Friday…

…Strong to severe late afternoon thunderstorms possible across the
east-central U.S for today and Thursday…

…First snowflakes of the season expected for the high elevations of
northwestern Montana today while fire weather threat blankets portions of
the northern Rockies…

A cold front has brought relief to the heat across the northern Plains
while triggering clusters of strong thunderstorms across the Midwest this
morning. As the front continues to push east and southeastward, a day of
record heat is expected to impact the Mid-Atlantic states where high
temperature could reach 100 degrees around the nation’s capital. This
heatwave will be relatively short-lived for the Mid-Atlantic as a much
cooler and damp air mass associated with a Canadian high pressure system
will quickly settle southward across the Great Lakes/New England into the
Mid-Atlantic by Thursday. However, much of the Ohio and Tennessee Valleys
will feel a couple more days of high temperatures topping into the upper
90s at the hottest locations as the next low pressure system marching
across the northern Plains will cease the southward progress of the cool
air and keep the heat in place for these areas. As the cold front
approaches, the hot air will be lifted and help trigger lines of
thunderstorms which can become severe along with locally heavy downpours
and very gusty winds. The highest threat for severe weather will be later
today into this evening from Ohio eastward across the northern
Mid-Atlantic near/after the time of maximum heating in the afternoon.
Some more strong thunderstorms could form Thursday afternoon farther
southward into the Mid-Atlantic on Thursday. Very cool air will then
blanket the entire Northeast on Thursday.

Meanwhile, the strong cold front associated with the next low pressure
system is marching across the northern Rockies. Sharply colder air behind
the system will likely bring the first snowflakes of the season for the
high elevations of northwestern Montana today while fire weather threat
blankets portions of the northern Rockies. The strong frontal system will
move steadily across the northern and central Plains on Thursday where the
threat of severe weather will be highest from Wednesday night across North
Dakota, then shifting east across a large chunk of the Midwest and upper
Midwest Thursday to Thursday night.

Farther south in Texas, an upper low had moved inland from the Gulf of
Mexico since yesterday. The instability has continued to help trigger
scattered thunderstorms across southern Texas. Meanwhile, deep southerly
flow to the east of the upper low has directed tropical moisture northward
from the Gulf toward the western Gulf Coast region, where some heavy
rainfall could develop in the vicinity during the next couple of days.
Elsewhere, while monsoonal moisture has become not as active and
widespread over the southern Rockies today, more focused activities across
southwestern New Mexico could lead to heavy rainfall. By Thursday, the
trailing cold front across the Plains will likely push the rain farther
east into the southern Plains where strong to severe storms are possible
by later in the day.

…A brief spell of record heat expected to spread from the Midwest to the
East Coast…

…Active showers and severe thunderstorms this morning across the
northern Plains and upper Midwest/Great Lakes will shift eastward into the
northern Mid-Atlantic/southern New England by late Wednesday into early
Thursday…

…First snowflakes of the season could reach the higher elevations of
northwestern Montana on Wednesday followed by a chance of severe
thunderstorms across North Dakota Wednesday night/early Thursday…

The closed upper high currently centered over the mid-Mississippi Valley
will be expanding eastward over the next two days, spreading into large
portions of the East Coast from the Mid-Atlantic southward. This will
send a quick spell of potentially record high temperatures from the
Midwest into the Ohio Valley, Tennessee Valley, southern to central
Appalachians and into the Mid-Atlantic. The combination of hot
temperatures in the mid to upper 90s to near 100 degrees together with
high humidity levels will produce maximum daily heat indices of between
105 and 115 degrees across these regions, with heat risks reaching major
to extreme levels today across the Midwest into lower Great Lakes.
Excessive Heat Warnings and Heat advisories are currently in effect across
the mid to upper Mississippi Valley, the Midwest and southern New England,
affecting nearly 61 million people, with further expansion of these
warnings and advisories possible into portions of the Mid-Atlantic for
Wednesday. This spell of record heat will be relatively short-lived as a
cool high pressure system settling into southern Canada is forecast to
send a cool and damp air mass into the Great Lakes on Wednesday and will
quickly overspread New England Wednesday night, reaching into the
Mid-Atlantic by Thursday morning behind a sharp cold front.

Around the peripheries of the above mentioned upper high, precipitation is
likely to be active along the Gulf Coast and from portions of the
Southwest, northeastward into the Central Plains, upper Mississippi
Valley, upper Great Lakes into northern New England in this “ring of
fire”. In these regions, moisture values are forecast to remain above
average, supporting the potential for areas of active thunderstorms, heavy
rains and flash flooding. Active showers and severe thunderstorms this
morning across the northern Plains and upper Midwest/Great Lakes could
result in areas of heavy rains and flash flooding. Some of these
thunderstorms are expected to shift eastward into the northern New England
by early Wednesday, before some additional strong to severe thunderstorms
and heavy rain possible across portions of the upper Ohio Valley, central
Appalachians and into the Mid-Atlantic later on Wednesday into early
Thursday ahead of the sharp cold front.

While much above to record high temperatures dominate portions of the
central to eastern U.S. into mid week, another strong front will be
pushing inland into the Pacific Northwest followed by the northern Rockies
and into the northern High Plains by this evening. Much below average
temperatures in the wake of this front will likely spread across the
Pacific Northwest for today and into the northern Rockies/northern High
Plains on Wednesday with high temperatures 10 to 20 degrees below average.
There is not expected to be a lot of precipitation with this front over
the Northwest, but the falling temperatures could bring the first
snowflakes of the season for the higher elevations of northwestern Montana
on Wednesday. By Wednesday night into early Thursday, a chance of severe
thunderstorms will be moving eastward across North Dakota ahead of the
strong cold front.
