…Another day of heavy rain and severe weather expected across the
central U.S. before shifting east into the Arklatex, Mid-Mississippi
Valley and Midwest by Monday night…

…Mountain snow moving across the Intermountain West and Rockies today
will begin to taper off on Monday as the next round of mountain snow and
wind quickly overspreads the Pacific Northwest on Monday…

…Above average temperatures approaching record levels will shift east
from the Plains today towards the Mississippi Valley by Monday with no
rain in sight along the East Coast…

The ongoing active weather system over the south-central U.S. will
continue to trigger additional rounds of heavy rain and severe weather for
the remainder of today, with the heaviest rainfall expected to impact
central to eastern Oklahoma into portions of northwestern Arkansas and
southern Missouri. More energy ejecting from the upper-level trough
currently spreading mountain snow across the Intermountain West will
eventually consolidate a low pressure system over the central High Plains
by tonight. This low pressure system will track northeastward across the
central Plains followed by another low pressure system to develop over the
south-central Plains on Monday. This second system is forecast to
push a cold front farther eastward Monday night, ending the heavy rain
threat across Oklahoma but shifting the heavy rain and severe weather
threats into the Arklatex region, Mid-Mississippi Valley and Midwest by
Monday night.

The upper trough will usher colder than normal temperatures through much
of the western U.S. for the next couple of days with mountain snow passing
through the Intermountain region today, followed by the central and
southern Rockies on Monday. Meanwhile, a rather strong low pressure
system from the Pacific Ocean will quickly spread the next round of
coastal rain into the Pacific Northwest on Monday followed by a good dose
of mountain snow farther inland along with quite a bit of wind. The
mountain snow will reach into the northern Rockies Monday night into
Tuesday morning as the low pressure system redevelops over the northern
High Plains. The greatest chances (>80%) for over 8 inches of snowfall in
a 24-hour period is forecast over the northern Cascades on Monday. Be
sure to prepare for winter driving conditions if traveling throughout
these elevated mountain ranges and stay tuned to the latest local weather
forecast.

Warmer and mostly dry conditions will be felt east of the Mississippi
River through early next week, besides rain chances entering parts of the
Midwest and Great Lakes. A large high pressure system centered over the
Great Lakes is forecast to slide eastward and off the New England
coastline by Monday, ushering in warm southerly flow on the western
periphery. This will support widespread above average high temperatures
into the upper 60s and 70s from the central/southern Plains to the
Mid-Atlantic by Monday, with 80s along the Gulf Coast States. When
compared to early November climatology, the Midwest is expected to
experience temperatures well above average on Monday. The anomalous
warmth will then spread across the Ohio Valley into the Great Lakes by
Monday night into early Tuesday as showers and thunderstorms ahead of the
cold front reach into the Midwest.

…Frequent rounds of heavy rain and severe weather expected across the
central and southern Plains throughout this weekend and into Monday…

…Mountain snow will spread from the Pacific Northwest into much of the
Intermountain West over the next couple of days…

…Much above average temperatures expected across large portions of the
central to eastern U.S. with no rain in sight along the East Coast…

An upper-level trough digging into the western U.S. will be pushing
against a ridge of high pressure building across the eastern U.S. This
will result an amplifying weather pattern across the mainland U.S. through
this weekend, with the most vigorous battle zone occurring over the
south-central U.S. As mountain snow being ushered into the western U.S.
with the arrival of the upper trough, a large high pressure system will
quickly build across the northeastern quadrant of the country today. This
high pressure system will settle and expand across the eastern two-thirds
of the country this weekend, bringing cooler air into the Northeast. In
contrast, widespread above average temperatures are expected from the
Plains eastward with no rain in sight along the East Coast into the first
few days of November.

Attention will then focus across the mid-section of the country where a
rather significant heavy rain and severe weather event is currently
developing. As moist air from the Gulf of Mexico returns and streams
northward into the southern Plains behind the high pressure system, the
deepening upper-level trough moving into the western U.S. will spread more
mountain snow across the Intermountain West this weekend. Southwesterly
flow ahead of the trough will then interact with the returning Gulf
moisture and lift the moisture over a warm front across the central and
southern Plains. Heavy rain associated with organized thunderstorms are
currently erupting over the southern High Plains. The thunderstorms and
heavy rain will then expand northeastward into the central Plains through
the weekend. A few inches of heavy rain with locally higher amounts is
forecast across the south-central U.S., with the heaviest rainfall
expected across central Oklahoma. Similar to many areas of the Lower 48,
this region is experiencing moderate to extreme drought conditions. While
this heavy rain event will help alleviate the drought, the expected high
rainfall rates will bring an increasing threat of flash flooding. WPC
currently has a moderate risk of flash flooding in place from central
Oklahoma to southeastern Kansas and into southwestern Missouri from Sunday
into early Monday. Please stay abreast of the latest forecast updates on
this upcoming heavy rain/severe weather event across the central to
southern Plains. This system will also spread some light to moderate rain
farther north across the northern Plains, and moderate to locally heavy
rain toward the upper Midwest on Sunday into early Monday.

…Threat of a heavy rain and severe weather event increasing across the
central to southern Plains throughout the weekend…

…Mountain snow will overspread from the Pacific Northwest into much of
the Intermountain West over the next couple of days with heavy rain today
near the Pacific Northwest coast…

…Much above average temperatures expected across large portions of the
central to eastern U.S. with little rain in sight along the East Coast…

A trailing cold front in connection with a low pressure system currently
moving east across the Great Lakes toward New England will bring a chance
of rain into the eastern U.S. on this first day of November following an
exceptionally dry October for this part of the country. However, it
appears that the rain will not progress much beyond the Appalachians today
as another day of warm and dry conditions is forecast for the East Coast.
In fact, the warm temperatures into the 70s early this morning have
already challenged high temperature records for November in upstate New
York. In addition, record high morning lows are possible this morning
from the Mid-Atlantic into New England and record high temperatures are
possible Friday afternoon from near New York City to northern Maine. The
cold front will bring gusty winds and cool temperatures into the Northeast
by tonight and into the weekend. While less record temperatures are
forecast over the next few days across the eastern two-thirds of the
country, widespread above average temperatures expected across large
portions of the central to eastern U.S.

A high pressure system will build across the Northeast during the weekend
and will sustain the dry conditions down the Eastern Seaboard for the
first few days of November. Attention will then focus across the central
and southern Plains as a rather significant heavy rain and severe weather
event will be emerging throughout the weekend. As moist air from the Gulf
of Mexico returns and streams northward into the southern Plains behind
the high pressure system, a deepening upper-level trough will be moving
through the western U.S. This trough will bring another round of heavy
rain near the coast for Pacific Northwest today before spreading more
mountain snow across the Intermountain West through the weekend.
Southwesterly flow ahead of the trough will then interact with the
returning Gulf moisture over the southern Plains and lift the moisture
over a warm front. It appears that moderate to heavy rain associated with
organized thunderstorms will first develop over the southern High Plains
tonight. The thunderstorms and heavy rain will then expand northeastward
into the central Plains through the weekend. A few inches of heavy rain
with locally higher amounts is forecast across the southern Plains, with
the heaviest rains expected across central Oklahoma. Similar to many
areas of the Lower 48, this region is experiencing moderate to extreme
drought conditions. While this round of heavy rain will help aleviate the
drought, the high rainfall rates will also bring an increasing threat of
flash flooding. Please keep abreast of the latest forecast updates on
this upcoming heavy rain/severe weather event across the central to
southern Plains.

Intermountain Region, with a second area over parts of the Upper Midwest
on Thursday…

…Temperatures will be 20 to 25 degrees above average over parts of the
Lower Great Lakes/eastern Ohio Valley and the Northeast/Mid-Atlantic…

…There is a Marginal Risk of severe thunderstorms over parts of the
Ohio/Tennessee Valley and Lower Mississippi Valley and a Marginal Risk of
excessive rainfall over parts of the Lower Mississippi Valley on
Thursday…

A wave of low pressure over the Upper/Middle Mississippi Valley will move
northeastward to Southeastern Canada by Friday. The trailing front moves
off the Northeast/Mid-Atlantic Coast by Friday evening, while the western
end of the boundary slowly moves northward as a stationary front over
north-central Texas by Saturday. Ahead of the front, temperatures will be
20 to 25 degrees above average over parts of the Lower Great Lakes/eastern
Ohio Valley and the Northeast/Mid-Atlantic.

On Thursday, moist air flowing northward over the Plains will extend into
the Great Lakes, creating showers and strong to severe thunderstorms ahead
of the front over parts of the Ohio/Tennessee Valley and Lower Mississippi
Valley. Therefore, the SPC has issued a Marginal Risk (level 1/5) of
severe thunderstorms over the Ohio/Tennessee Valley and Lower Mississippi
Valley through Friday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a minimal threat of tornadoes.

Furthermore, moderate to heavy rain will develop along the front over
parts of Tennessee and Lower Mississippi Valleys. Therefore, through
Friday morning, the WPC has issued a Marginal Risk (level 1/4) of
excessive rainfall over parts of the Tennessee and Lower Mississippi
Valleys. The associated heavy rain will create localized areas of flash
flooding, affecting areas that experience rapid runoff with heavy rain.

Moreover, the wave of low pressure will pull cold air over parts of the
Upper Midwest, producing moderate to heavy snow over parts of Minnesota,
extreme northern Wisconsin, and portions of the Upper Peninsula of
Michigan. Furthermore, rain develops along the front from Central
Appalachians to the Northeast on Friday morning, tapering off to scattered
rain over parts of the Northeast by Friday evening. Also, on Friday,
onshore flow off the Atlantic will produce scattered rain over parts of
Florida.

On Friday, the threat of strong to severe thunderstorms moves westward to
the Southern High Plains as upper-level dynamics move over Southern
California. Therefore, the SPC has issued a Marginal Risk (level 1/5) of
severe thunderstorms over parts of the Southern High Plains from Friday
into Saturday morning. The hazards associated with these thunderstorms are
frequent lightning, severe thunderstorm wind gusts, hail, and a minimal
threat of tornadoes

Further, the showers and thunderstorms will create moderate to heavy rain
over parts of the Southern Plains. Therefore, the WPC has issued a
Marginal Risk (level 1/4) of excessive rainfall over parts of the Southern
Plains from Friday to Saturday morning. The associated heavy rain will
create localized areas of flash flooding, affecting areas that experience
rapid runoff with heavy rain.

Meanwhile, another front over the Pacific Northwest and California will
move inland and dissipate by Thursday evening. On Thursday, the snow will
become moderate to heavy over parts of the Southern Cascades and Northern
Intermountain Region. Rain will continue over the Northwest and
Northern/Central California through early Saturday. Light snow will
continue over parts of the higher elevations of the Cascades, Sierra
Nevada Mountains, Northern Intermountain Region, and Northern Rockies.

the Great Lakes/Ohio Valley. A warm front over Northern New England will
move northeastward into Southeastern Canada by Thursday. Ahead of the warm
front, rain will develop over parts of Northern New England, ending by
Wednesday evening.

On Wednesday, moist air flowing northward over the Plains will extend into
the Upper Great Lakes, creating showers and severe thunderstorms will
develop ahead of the front over parts of the Middle Mississippi Valley and
Central/Southern Plains. Therefore, the SPC has issued an Enhanced Risk
(level 3/5) of severe thunderstorms over the Central Plains through
Saturday morning. The hazards associated with these thunderstorms are
frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes.

Moreover, southeasterly flow off the Gulf of Mexico will create scattered
showers and thunderstorms over parts of the Western Gulf Coast from
Tuesday into Wednesday. Similarly, easterly flow off the Atlantic will
produce showers and thunderstorms over parts of Florida through Thursday
morning. In addition, there is an increased threat of EF2 � EF5
tornadoes over the areas.

Furthermore, moderate to heavy rain will develop along the front over
parts of the Mississippi Valley and the Central/Southern Plains.
Therefore, the WPC has issued a Marginal Risk (level 1/4) of excessive
rainfall over parts of the Mississippi Valley and parts of the
Central/Southern Plains through Thursday morning. The associated heavy
rain will create localized areas of flash flooding, affecting areas that
experience rapid runoff with heavy rain.

On Thursday, the threat of severe thunderstorms from the Great Lakes to
the Lower Mississippi Valley will decrease to strong to severe
thunderstorms. Therefore, the SPC has issued a Marginal Risk (level 1/5)
of severe thunderstorms over parts of the Great Lakes to the Lower
Mississippi Valley from Thursday into Friday morning. The hazards
associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a few tornadoes.
