…Dangerous heat continues to impact large sections of the West into this
weekend…

…Heavy rain and instances of flash flooding are likely throughout the
central Gulf Coast and Southeast over the next few days…

…Showers and isolated severe thunderstorms possible from the Ohio Valley
to the Lower Great Lakes today…

An upper level high pressure system is expected to continue aiding well
above average and potentially dangerous temperatures throughout the West
into the first full weekend of September. Highs today are forecast to soar
into the triple digits for much of the Southwest and interior California,
with 110s in the typically hottest locations of the Desert Southwest.
Meanwhile, daily high temperature records are possible in the Northwest
where mid-to-upper 90s are in the forecast. A minimal relaxing of the
extreme heat should be felt throughout much of the West and Southwest on
Saturday, but with temperatures remaining above average. The core of the
anomalous heat will shift to the northern Great Basin and northern Rockies
as parts of eastern Oregon and Washington experience another day with
highs well into the 90s. Poor air quality will also remain an issue
throughout parts of the northern Great Basin as wildfire smoke continues
to plague the region. Residents and visors are advised to follow proper
heat safety, which includes checking on vulnerable individuals.

Not much heavy precipitation to speak of throughout the Nation over the
next few days besides along the Gulf Coast and parts of the Southeast. A
lingering stationary front and a couple waves of low pressure will provide
a focus for tropical downpours over already saturated soils. The greatest
threat for heavy rainfall turning into flash flooding impacts are forecast
across southeast Louisiana today, where a Moderate Risk (level 3/4) of
Excessive Rainfall has been issued. Several inches of rain occurring
within a very short period of time could lead to numerous flash floods
here. A scattered flash flood threat also extends eastward along and just
north of the stationary front into northern Florida and southern Georgia.
This frontal boundary is expected to gradually sink southward by Saturday
as an area of low pressure exits off the Southeast coastline, with a
persisting isolated flash flood potential extending from the central Gulf
Coast and northern Florida to the coastal Carolinas. Remember, most flood
fatalities occur within vehicles… turn around, don’t drown.

Elsewhere, a cold front sweeping across the Ohio Valley and Lower Great
Lakes will usher in below average temperatures throughout the Great Lakes,
Midwest, before reaching the East Coast by this weekend, while also
producing areas of showers and thunderstorms. A few storms could produce
locally gusty winds and hail today in the Ohio Valley and nearby Lake Erie
region. Scattered showers are expected to progress eastward along the cold
front on Saturday and dampen weekend plans throughout the Interior
Northeast and sections of New England by Saturday evening.

…Very heavy rain and the threat for scattered to numerous instances of
flash flooding continues for the Gulf Coast states the next couple of
days…

…Dangerous heat wave intensifies over the Southwest and West Coast…

Heavy rain and flash flooding remain in the forecast along the Gulf Coast
as a stationary front and coastal low drive multiple days of widespread
showers and thunderstorms across the region. The elongated area of low
pressure and front from the north-central to western Gulf will keep the
greatest focus for repeated rounds of storms moving onshore over the
central Gulf Coast and upper Texas Gulf Coast today (Thursday),
potentially spreading a bit further northward into the Lower Mississippi
Valley. Very moist Gulf air continues to contribute to very efficient
downpours with these storms, approaching 2-3″ per hour in some cases,
exacerbating the threat for heavy totals and flash flooding. There is now
a Moderate Risk (level 3/4) of Excessive Rainfall for southeastern
Louisiana where prior days rainfall has lead to very wet antecedent
conditions and brings a locally greater threat for scattered to numerous
instances of flash flooding, especially for the urban areas around greater
New Orleans. A broader Slight Risk (level 2/4) is in place across the
region for additional scattered instances of flash flooding. An
approaching upper-level wave will help to shift the focus for heavy
rainfall a bit eastward on Friday as the front begins to meander away from
the western Gulf and lift northward into southern Georgia, leading to
decreasing rain chances further West. Another Slight Risk of Excessive
Rainfall extends from the central Gulf Coast eastward through the Florida
Panhandle into southern Georgia where a similar threat for intense heavy
downpours with repeated rounds of storms will lead to several inches of
rain, and the potential for scattered instances of flash flooding.
Temperatures will remain well below average across the region north of the
frontal boundary and in the presence of widespread rain and cloud cover
with mostly upper 70s and low 80s. Some locations may only reach into the
low 70s Friday. On the other hand, it will be hot south of the front
across the Florida Peninsula, with highs in the low 90s. A Heat Advisory
is in place for South Florida where the combination of heat and humidity
will lead to heat indices in the 105-110 degree range.

A dangerous heat wave will intensify over the Southwest and West Coast the
next couple of days with a strong upper-level ridge now settled over the
region. Forecast high temperatures Thursday and Friday range from the 110s
for the Desert Southwest, low 100s to near 110 for southern California,
mid-100s for the central California Valleys, and the 90s to low 100s for
central/northern California and into the Pacific Northwest. Several
record-tying/breaking highs are possible across the Pacific Northwest.
Widespread heat-related warnings and advisories are in place given the
heightened threat for heat-related illness to anyone without efficient air
conditioning or adequate hydration. While not quite as hot, highs will be
well above average and potentially uncomfortable even for some immediate
coastal locations with temperatures reaching into the 80s.

Elsewhere, a broad area of showers and thunderstorms is expected ahead of
a pair of cold fronts passing through the Upper Midwest/Great Lakes,
Central Plains, and central/southern High Plains and adjacent Rockies. The
greatest chance for some moderate to locally heavy rainfall will be under
the influence of an upper-level trough over the Upper Midwest/Great Lakes,
and where upslope flow enhances storms over the southern Rockies. A few
isolated instances of flash flooding will be possible in the southern
Rockies given recent rains and some more sensitive burn scars. Storm
chances with moderate to locally heavy rainfall will continue ahead of the
front as it pushes eastward through the Great Lakes overnight Thursday and
into the Lower Great Lakes/Upper Ohio Valley on Friday. Some storms may
begin to spread into the Northeast and Mid-Atlantic by early Saturday
morning. Temperature-wise, the passing cold front will bring well below
average, Fall-like temperatures to the Northern Plains and Upper Midwest
Thursday, with highs in the 60s to low 70s. Temperatures will be rather
chilly for the Upper Great Lakes by Friday as highs drop into the 50s.
Conditions will be much warmer ahead of the front Thursday over the
Midwest and Ohio Valley with highs in the mid-80s to low 90s. The
approaching front will bring temperatures down into the 70s for portions
of the Midwest Friday. Mild conditions will continue for much of the East
Coast through Friday with highs in the upper 70s to low 80s.

…Heat wave builds over the Southwest and the West Coast this week…

…Heavy rain and flash flood potential continues for the Gulf Coast
states the next couple of days…

An upper-level ridge building northward over the West Coast will help to
expand and intensify a heat wave over the region through the next few
days. Forecast highs today (Wednesday) range from the upper 100s to
mid-110s in the Desert Southwest, the mid-90s to low 100s for southern and
central California, and the mid-90s to low 100s for portions of the
Pacific Northwest. Temperatures soar even higher on Thursday, with highs
into the 110s for the Desert Southwest, the 100s to near 110 in southern
California, the mid-100s for the central California Valleys, and the low
100s for portions of the Pacific Northwest. Widespread heat-related
warnings and advisories are in place as the threat for heat-related
illness and impacts will increase today and especially on Thursday. This
heat will be dangerous to anyone without effective air conditioning or
sufficient hydration. While not quite as hot, temperatures will also be
well above average along the immediate Pacific Coast, with highs into the
80s for many locations.

Heavy rain and the threat for flash flooding will remain in the forecast
for the Gulf Coast states this week as a stationary front and coastal low
drive multiple days of widespread showers and thunderstorms across the
region. The placement of the elongated area of low pressure in the western
Gulf will keep the focus for the most widespread rainfall over portions of
the central and upper Texas Gulf Coasts, and possibly a bit further north
into the Lower Mississippi Valley. Extremely moist Gulf air will lead to
very heavy downpours (upwards of 2-3″ per hours rates) with continued
rounds of storms moving onshore. Forecast areal average rainfall totals
are in the 3-5″ range, with locally higher amounts of 7″+ possible, most
likely near the immediate coast. A Slight Risk of Excessive Rainfall
(level 2/4) is in place for the region both today and tomorrow given the
threat for scattered instances of flash flooding. Storms will also
increase along the southeastern Atlantic Coast today and Thursday, and
daily thunderstorm chances will continue for the Florida Peninsula. The
passage of the frontal boundary to the coast and widespread storms and
clouds will keep temperatures down across Texas and the Southeast the next
couple of days, with highs generally in the 80s. Conditions will be hotter
south of the boundary in Florida with temperatures into the 90s. A Heat
Advisory is in place for South Florida today as the combination of highs
into the 90s and high humidity will lead to heat indices in the 105-110
degree range.

Elsewhere, much of the eastern U.S. outside of the the South will be dry
with generally mild temperatures. Early Fall-like highs in the 70s are
expected throughout New England, the Mid-Atlantic, and Carolinas through
Thursday. An upper-level ridge passing over the Midwest will bring
temperatures back up into the mid- to upper 80s over the next couple of
days. An approaching upper-level trough/surface frontal system will bring
shower and thunderstorm chances to portions of the Central/Northern Plains
and Upper Midwest today, with the greatest storm coverage and chance for
some more moderate rainfall in the Upper Midwest and the central High
Plains/adjacent Rockies. The frontal system will push further
southeastward on Thursday, bringing storm chances to the Great Lakes,
Central Plains, and central/southern High Plains/adjacent Rockies. Once
again, the greatest storm coverage and heavier rainfall will be focused to
the north over the Great Lakes and to the southwest over the
central/southern High Plains and adjacent Rockies. Some isolated flash
flooding will be possible over the southern Rockies given more sensitive
soils from recent rainfall and over any burn scars.

…Areas of heavy rain and the potential for flash flooding continue in
Texas and along the Gulf Coast the next couple of days…

…One more day of late-Summer heat for the north-central U.S. Tuesday
before focus shifts to a building heat wave in the West Wednesday…

Thunderstorms capable of producing heavy rainfall will persist across
portions of Texas and along the Gulf and southeastern Atlantic Coasts this
week as very moist Gulf air pools around a quasi-stationary frontal
boundary lingering through the region. A passing upper-level disturbance
will lead to more widespread storms once again today (Tuesday) over
portions of central Texas where a locally greater threat for some flash
flooding will exist, with a Slight Risk of Excessive Rainfall (level 2/4)
outlooked for the region. Further east along the central Texas Gulf Coast,
very moist, onshore flow aided by a stubborn coastal low and continued
rounds of storms moving inland will bring further heavy downpours that
could lead to several inches of rainfall. A Slight Risk of Excessive
Rainfall has been included here as well as wet antecedent conditions from
rainfall over the past few days will increase the threat for some
additional instances of flash flooding in the area. The upper-level
disturbance will lift northeastward on Wednesday, increasing storm
coverage over the central Gulf Coast and possibly north into the Lower
Mississippi Valley. Another Slight Risk of Excessive Rainfall is in place
given the threat for heavy downpours and scattered flash flooding. Storms
will also increase along the southeastern Atlantic Coast by Wednesday, and
daily thunderstorm chances will continue for the Florida Peninsula.

Further north, an upper-level trough and associated surface cold front
will bring showers and thunderstorms to the northern Rockies today. Some
locally heavy downpours will be possible with an isolated threat of flash
flooding over central Idaho and southwestern Montana. Ahead of this
system, an upper-level ridge over the northern/central High Plains will
lead to another day of well above average, hot late-Summer temperatures,
particularly over the northern High Plains. Forecast highs are into the
90s, with some upper 90s possible for the western Dakotas. The approaching
system from the west will help to bring temperatures back down to average
Wednesday, with highs in the low to mid-80s. Showers and storms are
expected with the passage of the system, particularly over the central
High Plains. Storms chances will also spread into the Upper Midwest as the
system continues east Wednesday night.

Attention in the mid- to late week will turn to a building heatwave over
the West. A strong ridge will settle in over the West Coast following the
passage of the upper-trough over the northern tier, with highs on Tuesday
already beginning to climb into the upper-90s and low 100s over interior
California and 100s to 110s in the Desert Southwest. Then, on Wednesday,
temperatures will soar into the low 100s over interior California and into
the 90s in the Pacific Northwest. While not as hot, much above average
temperatures are expected for coastal areas too, with highs into the low
80s for some locations. Heat-related warnings and advisories have been
issued for the Desert Southwest and central/southern California outside of
the immediate coast given a heightened risk for heat-related illness,
especially for those without access to effective air conditioning.
Elsewhere, most of the eastern U.S. outside of the the South will be dry
with generally mild temperatures. Early Fall-like highs in the 70s are
expected throughout New England, the Mid-Atlantic, and Carolinas.

…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.
