…Heavy rain threat emerges across the Deep South late Sunday into
Monday…

…Periods of mixed rain and snow linger from the Great Lakes to northern
New England through Monday night…

…Unsettled and windy weather spreading across the Pacific Northwest this
weekend will reach into the northern Plains as snow/wintry mix by Monday…

…Well above average temperatures will overspread the central and eastern
U.S. as cold air surges into the western U.S….

A major reversal of the weather pattern is forecast to occur across
mainland U.S. during the next couple of days. The remaining cold air
across the eastern U.S. originated from the recent arctic outbreak will be
dispelled by an eastward expanding mild air mass from the central U.S.
Meanwhile, the mild air across the western U.S. in recent days will be
dispelled by a surge of cold air currently advancing through the
northwestern U.S. The upper-level trough responsible for this cold surge
into the western U.S. will first spread mixed rain and snow through the
northern Rockies today behind a cold front along with windy conditions.
Daytime heating will keep the precipitation mainly in the form of rain as
it moves quickly across the northern Plains today. By tonight, colder air
from Canada is forecast to filter south from Canada behind a low pressure
system. This will bring periods of snow into the northern Plains and
areas farther west to the foothills of the northern Rockies through
tonight and into Monday, along with windy conditions. The higher elevations
will receive higher amounts of snow, with the highest snowfall likely near
the northern slopes of the Black Hills where more than a foot of new snow
is possible. Portions of the central Rockies into the Front Range of
Colorado and down into northeastern New Mexico can expect to receive a
period of snow from this system through Monday night into Tuesday morning.

Ahead of the cold front trailing south from the aforementioned low
pressure system, a jet stream sliding across northern Mexico will interact
with a coastal front and a low pressure wave near the western Gulf Coast
to bring an increasing threat of heavy rain farther inland across the
lower Mississippi Valley and then into the Deep South through the next
couple of days. Warmer and more unstable air arriving from the Gulf will
help trigger heavier showers and thunderstorms for the eastern portion of
these areas. The overlapping elements coupled with some recent rainfall
will result in the possibility of scattered instances of flash flooding.
The Weather Prediction Center maintains a Marginal Risk of Excessive
Rainfall across the central Gulf Coast region for Monday into early
Tuesday, with a Sight Risk area from southeastern Louisiana to southern
Mississippi.

Across New England, widespread snowfall is in progress today ahead of a
clipper system moving quickly eastward along a warm front lifting north
across the region. Widespread snowfall of up to 6 inches can be expected
from the Adirondacks eastward through Maine before the snow tapers off
tonight. More snow will then skirt the upper Great Lakes ahead of the
warm front associated with the northern Plains low pressure system, with
6-8 inches expected over the Upper Peninsula of Michigan and the Arrowhead
of Minnesota. A period of rain will sweep across the Ohio Valley Sunday
night, then the Appalachians and the northern Mid-Atlantic on Monday ahead
of the trailing front, followed by the next round of snow across northern
New England Monday night. Mild Atlantic air will keep the precipitation
as rain for southern New England into Tuesday morning.

…Periods of mixed rain and snow linger from the Great Lakes to northern
New England through the weekend…

…Heavy rain threat emerges across the Deep South late Sunday into
Monday…

…Unsettled and windy weather spreading across the Pacific Northwest this
weekend will reach into the northern Plains as snow by Monday…

…Arctic air across the eastern U.S. will give way to above normal
temperatures by Monday…

As an arctic high pressure system moderates and retreats across the
eastern portion of the country, unsettled weather will emerge and expand
across the Deep South as well as the Pacific Northwest. Moisture
returning behind the high pressure system today will begin to interact
with an upper-level trough and a coastal front just off the Texas coast.
This will result in expanding areas of light to moderate rain with
embedded thunderstorms across the eastern two-thirds of Texas today. The
entire system will shift northeastward on Sunday before evolving into a
heavy rain threat across the lower Mississippi Valley toward the Tennessee
Valley by late Sunday into early Monday. A couple of inches of rain is
expected in this general vicinity with locally higher amounts through
Monday morning.

Meanwhile, periods of mixed rain and snow are expected to linger across
the Great Lakes and into northern New England where a clipper low pressure
system is forecast to track along a nearly stationary arctic front. Up to
a foot of new snow is possible near the Canadian border in these areas.

The Pacific Northwest is entering a period of increasingly unsettled
weather as a rather dynamic upper trough arrives from the Pacific.
Low-elevation rain and high-elevation heavy snow can be expected for the
Cascades and northern Idaho as the weekend progresses with windy
conditions. The mountain snow and low-elevation rain will progress
farther inland into the northern Rockies early Sunday as a low pressure
system begins to develop across the northern High Plains into Alberta
Province of Canada. Winter Storm Warnings and Advisories are active
across the northern Rockies through Saturday where several inches of
snowfall and some icing potential will create hazardous travel conditions.
Meanwhile, much of the remainder of the western U.S. will remain dry and
milder than normal as high pressure dominates. By Sunday night into
Monday morning, a low pressure system is forecast to track across the
northern Plains with snow and wind. Mainly light snowfall amounts are
expected for North Dakota into Montana, with high amounts enhanced by
local terrains.

Low temperatures in the 20s as far south as the Florida Panhandle this
morning have prompted Freeze Warnings for portions of northern Florida
into Georgia. High temperatures will begin to moderate across the East by
Sunday as anomalously mild temperatures across the central U.S. shift
eastward into the region. Highs should be in the 60s and 70s Sunday across
the Southeast and 50s and 40s across the Mid-Atlantic and Northeast, while
50s and 60s will expand across the northern and central Plains Sunday
afternoon ahead of the developing low pressure system.

…More lake-effect/lake-enhanced snow downwind from Lakes Erie and
Ontario…

…Arctic air currently engulfing much of the eastern U.S. will gradually
moderate over the next couple of days…

…Dry and milder than average temperatures in the western U.S. will
spread into the northern and central U.S. through the next couple of
days…

Under an intense surge of arctic air, Friday morning will begin with the
coldest temperatures so far this season across much of the central and
eastern U.S. with blustery conditions and a piercing wind chill. The
persistent flow of arctic over the relatively warm waters of the Great
Lakes has continued to bring lake-effect snows downwind into the Snow
Belt. By later today into tonight, another clipper currently forming
along the arctic front will spread more snow across the Great Lakes from
northwest to southeast. By Saturday, still another clipper will bring
more widespread snowfall across the upper Great Lakes, reaching into the
lower lakes Saturday night. Milder air could change some of the snow to
rain Saturday afternoon near the western fringe of these areas. As much
as two additional feet of new snow is possible near the eastern shore of
Lake Ontario through the next couple of days. Lighter snowfall amounts
can be expected elsewhere along the Snow Belt.

After a morning with wind chills possibly falling below zero across the
mountains of the Applachains, conditions are expected to improve through
the next couple of days as southwesterly winds begin to bring milder air
from the western U.S. into the northern and central Plains. The most
drastic recovery will be found over the northern High Plains where high
temperatures could top 60 degrees by Saturday afternoon.

The retreating arctic high pressure system that brings the milder air into
the northern U.S. will also bring increasing moisture into Texas. It
appears that rain will expand in coverage across southern to eastern Texas
through Saturday ahead of an upper trough. Additional influx of moisture
from the Gulf of Mexico could begin to raise the threat of heavy rain from
eastern Texas into Louisiana by early on Sunday.

After a tranquil Friday, increasingly unsettled weather is expected for
the Pacific Northwest by the weekend. Rain showers and some high elevation
snow will return to Washington State and Oregon by Saturaday as the next
front moves through. The mountain snow and low-elevation rain will
progress farther inland, reaching into the northern Rockies by early
Sunday as a low pressure system begins to develop across the northern High
Plains into Alberta Province of Canada. Much of the remainder of the
western U.S. will remain dry and milder than normal as high pressure
dominates the region. High temperatures will be in the 80s across the
Southwest while 70s and 60s will prevail from southern California to the
Pacific Northwest.

…Heavy lake-enhanced/lake-effect snow downwind from Lakes Erie and
Ontario on Thursday and Friday; Moderate to heavy snow over parts of New
England on Thursday; light to moderate snow over parts of the Central
Appalachians on Thursday and Friday…

…Light to moderate lake-effect snow for the Upper Peninsula of Michigan
and the west coast of the Lower Peninsula on Thursday and Friday…

…Temperatures will be 10 to 20 degrees below average over parts of the
Ohio Valley and the Mid-Atlantic…

A storm over southeastern Canada will move eastward to far eastern Canada
by Friday morning. The system will produce heavy lake-enhanced then heavy
lake-effect snow downwind from Lakes Erie and Ontario on Thursday and
Friday. Additionally, in the wake of the storm, light to moderate
lake-effect snow will develop over parts of the Upper Peninsula of
Michigan and the west coast of the Lower Peninsula of Michigan on Thursday
and Friday. Further, moderate to heavy snow will be created on Thursday
over parts of New England. By Friday, scattered light snow will be over
New England and then the snow will end by Friday evening. Furthermore,
light to moderate snow will develop over parts of the Central Appalachians
on Thursday and Friday.

Moreover, the strong arctic cold front will sweep across the Mid-Atlantic
and the Northeast on Thursday. The boundary will create snow squalls
accompanied by intense bursts of heavy snowfall and gusty winds, producing
dangerous travel conditions due to whiteouts and icy roads.

In addition, wind gusts up to 50 mph will spread into the Central
Appalachians, Mid-Atlantic, and Northeast on Thursday. These winds may
cause power outages, down tree branches, and result in hazardous commutes.

Moreover, after the storm, high pressure over the Northern Plains will
move southeastward to the Tennessee Valley by Saturday. The high pressure
will usher in cold temperatures over parts of the Ohio Valley and the
Mid-Atlantic, bringing temperatures of 10 to 20 degrees below average.

Meanwhile, return flow off the Gulf of Mexico will create scattered
showers and thunderstorms over parts of the Central Gulf Coast on
Thursday. On Friday, scattered showers and thunderstorms will develop over
parts of the Southern High Plains.

Elsewhere, lingering stagnant air conditions will be over parts of the
Pacific Northwest, leading to areas of dense fog and poor air quality.
However, an approaching front over the Eastern Pacific will usher moisture
into the Pacific Northwest, creating light rain over parts of the
Northwest Coast late Friday night into Saturday.

Wednesday and Thursday; Heavy snow over parts of Northern New England;
light to moderate snow over parts of the Central Appalachians on
Wednesday…

…Temperatures will be 10 to 15 degrees below average over parts of the
Mid-Atlantic and the Southeast…

On Wednesday, high pressure over the Southeast will move southeastward off
the Southeast Coast by Wednesday night. The high pressure will create cold
temperatures over parts of the Mid-Atlantic and the Southeast, bringing
temperatures of 10 to 15 degrees below average.

Meanwhile, low pressure just north of Lake Superior will move eastward to
Southeast Canada by Friday. The storm will produce heavy snow over the
Upper Peninsula of Michigan and the northern Lower Peninsula of Michigan
through Thursday morning. Moreover, heavy lake-enhanced snow will develop
downwind of Lakes Erie and Ontario through Friday. Additionally, heavy
snow will develop over New England through Friday too.

Furthermore, light snow will develop over parts of the Northern
Plains/Upper Mississippi Valley and the Ohio Valley from Wednesday through
Friday. Moderate to heavy snow will develop over parts of the Central
Appalachians through Friday. Rain will also develop over the coastal parts
of New England through Thursday afternoon and then change over to snow.

Moreover, weak return flow off the Gulf of Mexico will create scattered
showers and thunderstorms over parts of the West/Central Gulf Coast
through Wednesday and Thursday. Some of the rain will be moderate to heavy
over parts of the Western Gulf Coast. Therefore, the WPC has issued a
Marginal Risk (level 1/4) of excessive rainfall over parts of the Western
Gulf Coast through Thursday morning. The associated heavy rain will
create localized areas of flash flooding, affecting areas that experience
rapid runoff with heavy rain.

Rain will also expand along the Eastern Gulf Coast into the Southeast on
Thursday and into parts of the Southern High Plains Thursday night into
Friday.

Elsewhere, upper-level ridging will create stagnant air conditions over
parts of the Pacific Northwest, leading to areas of dense fog and poor air
quality. However, an approaching front over the Eastern Pacific will usher
moisture into the Pacific Northwest, creating light rain over parts of the
Northwest Coast late Wednesday night into Friday.
