…Severe weather and isolated flash flooding for the Middle
Mississippi/Lower Ohio Valleys and Southern Plains Thursday…

…Showers, thunderstorms, and cooler weather for much of the Southern
Plains Friday; wintry mix into the central High Plains…

…Unseasonably warm conditions for much of the southern U.S.; chillier
weather expands across the northern Rockies/Plains and Upper Midwest…

A weakening system over the Northeast will bring some shower chances to
the northern Mid-Atlantic into New England Thursday. To the west, a much
broader area of showers and thunderstorms is expected ahead of a cold
front from the Middle Mississippi/Lower Ohio Valleys southwestward through
the Southern Plains. Sufficient shear and instability will be in place in
the Middle Mississippi/Lower Ohio Valleys for some organized
thunderstorms/line segments, with the Storm Prediction Center noting an
Enhanced Risk (level 3/5) for severe weather. Very large hail, damaging
winds, and a few tornadoes will all be possible. A Slight Risk (level 2/5)
extends southwestward along the front into Texas, with a more isolated
threat for some large hail and damaging winds. The prospect of widespread
storm coverage, especially for areas further north through the Middle
Mississippi Valley, and the potential for heavy downpours may lead to some
isolated flash flooding as well.

Shower and thunderstorm chances will progress eastward with the advancing
cold front into the Appalachians by Friday morning and eventually the East
Coast by Friday evening, though coverage and intensity looks to trend
downward during the day as the front approaches the coast. A few isolated
severe thunderstorms may occur over the Southeast. Areas of moderate to
rainfall will linger over portions of the Southern Plains along and north
of the cold front over Texas as it begins to slow and stall over the
region. Some isolated flooding will be possible. Post-frontal upslope flow
will also bring precipiation chances to the central High Plains and Front
Range of the Rockies, with a mix of rain and snow showers for lower
elevations and snow into the mountains. Any accumulations at the lower
elevations should remain minimal.

Forecast high temperatures remain rather warm to even hot across southern
portions of the country Thursday, with highs in the mid-80s to near 90
from Texas eastward through the Southeast, and even as far north as
portions of the Middle Mississippi and Lower Ohio Valleys. Areas of west
Texas and along the Rio Grande Valley will see mid- to upper 90s.
Conditions will be similarly hot in the Desert Southwest. The southerly
progression of the cold front will bring much cooler temperatures Friday
across northern Texas and into the Mid-South and Tennessee Valley as highs
drop into the 60s and 70s. Conditions will remain hot south of the frontal
boundary. Further north, highs will range in the 50s and 60s across the
central Plains northeastward into the Great Lakes region, with 60s and 70s
from the Ohio Valley into the southern Mid-Atlantic. The northern
Mid-Atlantic into New England will be a bit chilly Thursday with highs in
the 40s and 50s, with temperatures expected to recover a bit Friday. Cold
temperatures will also expand in coverage across the northern
Rockies/Plains and Upper Midwest as high pressure settles in over the
region, with highs in the 30s and 40s. In the West, highs will range from
the 60s and 70s from the Pacific Northwest southward through coastal
California and inland across the Great Basin, with 80s for the central
California valleys.

…Lake effect snow continues across the Great Lakes before a developing
low pressure system spreads snowfall east into northern New England on
Wednesday…

…Light to moderate snow enters the northern Plains midweek and pushes
into the Upper Midwest on Thursday…

…Shower and thunderstorm chances return to the southern Plains and
western Gulf Coast…

Cold northwest flow crossing over relatively warm lake waters will lead to
additional lake effect snow showers today, which will be further enhanced
as a low pressure system crosses from southern Ontario, Canada towards
Maine by early Thursday. Greatest probabilities for at least 4 inches of
snow exist across the eastern U.P. of Michigan and the Tug Hill Plateau of
western New York. As the low pressure system deepens over eastern Maine on
Thursday, additional snowfall is expected to develop just to its northwest
throughout northern Vermont, New Hampshire, and Maine. Medium
probabilities (40-70%) for at least 6 inches of snow is currently depicted
across this region. Gusty winds and below average temperatures are
forecast in the system’s wake, with highs only expected to reach into the
30s and 40s throughout the Great Lakes, Ohio Valley, and Northeast.

Snow potential also returns to the northern Plains and northern Rockies on
Wednesday due to the combination of a nearby stationary front and
favorable jet stream dynamics. Far northwest Montana and the Yellowstone
region currently have the best chances for accumulating snow to add up to
over 4 inches. By Thursday, a developing low pressure system along the
aforementioned stationary front is anticipated to progress eastward across
the northern Plains and towards the Upper Midwest. This will spread light
to moderate snow from parts of the Dakotas to central/southern Minnesota,
far northern Iowa, and Wisconsin. Uncertainty remains on exactly where the
heaviest snowbands may set up, but residents should remain weather aware
and prepare for potentially difficult travel across the Upper Midwest
between Thursday night and Friday morning.

For the southern Plains, rain and thunderstorm chances return on Wednesday
as an upper low lingering over the Southwest finally ejects eastward. A
few isolated thunderstorms could turn severe over western Oklahoma and the
Texas Panhandle, as well as south-central Texas. By Thursday, heavy rain
may develop along the Texas and Louisiana Gulf Coast, which could lead to
isolated flooding concerns.

As far as the temperature highlights for the short term time period, a
frost/freeze threat remains this morning from the Lower Mississippi Valley
to the Southeast as lows dip into the 20s and 30s. This cold snap is
forecast to be short-lived as temperatures warm to near average by
Thursday across the South. Meanwhile, above average temperatures are
expected today across the central Plains and Northwest. Afternoon highs
could break daily temperature records throughout the northern Great Basin
as thermometer readings soar into the 70s.

…Locally heavy rains are expected to sweep across coastal New England
early today with gusty winds…

…Heavy wet snow and strong winds are expected across northern New
England through today followed by lake-effect snows across the lower Great
Lakes into Monday morning…

…Unsettled weather is expected to persist across the Pacific Northwest
and into the northern Rockies with multiple rounds of lower-elevation rain
and higher elevation snow…

An intensifying low pressure system that brought another round of moderate
to heavy rain across the northern Mid-Atlantic to New England Saturday
night into Sunday morning will continue to track northeast through coastal
New England. Colder air wrapping around the expanding storm will support
heavy wet snow today across northern New England, especially over the
higher elevations of upstate New York, Vermont, New Hampshire and Maine
where winter storm warnings are in effect. As much as 6 to 12 inches of
heavy wet snow can be expected in these areas along with increasingly
strong and gusty winds. Meanwhile, much of the East Coast will be drying
out today after yesterday’s rainfall but blustery winds from the northwest
will usher in chilly air. The cold air passing over the relatively warm
waters of the Great Lakes will promote lake-effect snow showers and
localized snow squalls downwind from the lower Great Lakes toward the
central Appalachians today. The snow showers are expected to linger into
Monday but they will gradually taper off as the huge storm will take some
time to move farther away into the Canadian Maritimes.

In the wake of the huge storm circulation, a large high pressure system
will take over and provide a few days of tranquil and dry weather from the
Four Corners eastward through the Great Plains and for the entire eastern
U.S. Cool and dry weather will prevail across the South and the Southeast
including Florida. A warming trend will set in across the northern Plains
today as southerly winds and downslope flow help expanding the warmth
eastward into the upper Midwest by Tuesday when some daily record high
temperatures are possible.

Meanwhile across the Pacific Northwest, multiple low pressure systems
arriving from the Pacific will bring frequent rounds of precipitation
onshore and then farther inland through the next couple of days. Moderate
to locally heavy rain is expected for the coastal ranges with heavy snow
over the higher elevations of the Cascades, northern Sierra Nevada, and
the Sawtooth and Bitterroot range of the northern Rockies. The heaviest
snows should be over the Washington Cascades going through Monday where 1
to 2 feet of new snow can be expected.

…Heavy snow over parts of the Cascades, the Northern Intermountain
Region, Northern Rockies, Northern California, and Sierra Nevada
Mountains…

…Heavy lake-effect snow southeast of Lake Ontario and over the Upper
Great Lakes…

…Rain from the Gulf Coast to parts of northern Mid-Atlantic and shower
and thunderstorms along the Central Gulf Coast and Southeast…

A second winter storm will impact the West Coast on Thursday and Friday.
The storm will create heavy mountain snow that will affect many passes.
Multiple feet of snow are likely (over 80% chance) for higher elevations,
especially above 5000 feet, including many Cascade and Sierra Nevada
Mountain passes. Extremely heavy snow rates surpassing 3 inches per hour
are likely.

Furthermore, the storm will produce blizzard conditions in the Sierra
Nevada Mountains. In detail, strong winds will cause significant
blowing/drifting snow and whiteout conditions, making travel impossible in
the Sierra Nevada Mountains. There is a high chance (over 70%) of
substantial, long-lasting disruptions to daily life in the higher
elevations of the Sierra Nevada Mountains Friday-Saturday, where blizzard
conditions and 5+ feet of snow are expected.

Moreover, in addition to the snow, coastal rain will develop over parts of
the Pacific Northwest Thursday into Saturday. Coastal rain will develop
over parts of California Thursday morning, continuing into Saturday.

In addition, the widespread damaging wind will develop over the Western
U.S. Wind gusts of 55+ mph are forecasted across much of the West,
particularly across higher elevations and the Intermountain West, where
75+ mph gusts are possible. These winds would likely down trees and power
lines, resulting in power outages across affected areas.

Further, cold air will lower snow levels Friday into Saturday. As the
storm moves south, snow levels will lower into some Northern California
and Sierra Nevada Mountain foothill communities. Much colder air is
forecast for Saturday, with temperatures 10-20 degrees below normal.

Meanwhile, upper-level energy moving across the Great Lakes into the
Northeast will create lake-effect snow over the northeast portion of the
U.P. of Michigan, with the heaviest lake-effect snow southeast of Lake
Ontario on Thursday.

Additionally, upper-level energy moving over the Southern Rockies will
move eastward to the Mid-Atlantic by Saturday, producing rain and
higher-elevation snow over the Southern Rockies Thursday. Overnight
Thursday, showers and thunderstorms will develop over parts of the
Southern Plains, moving into the Lower Mississippi, Tennessee, and
Southern Ohio Valleys and parts of the Southeast by Friday. The showers
and thunderstorms will continue over parts of the Southeast through
Saturday. On Friday, rain will move into parts of the Mid-Atlantic and
Ohio Valley, moving into parts of the Northeast by Saturday. Also, on
Friday, scattered pockets of rain/freezing rain will develop over the
highest elevations of parts of the Central/Southern Appalachians.
