…Heavy snow over Upstate New York, Northern New England, the Sierra
Nevada Mountains, and Central Appalachians on Thursday…

…Moderate to heavy snow over the Northern Intermountain Region on
Friday…

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

A deep storm over the Great Lakes and the Northeast will slowly move off
the Northeast Coast by Saturday. The system will produce heavy, wet snow
over north-central New England and northeast New York and later spread
north through Maine on Thursday. Snowfall rates then decrease, but snow
continues over Northern New England into Friday. Snowfall accumulations of
1-2 feet are 60 to 70 % likelihood for much of Northern New England and
the northeast part of the Adirondacks. Furthermore, heavy snow will
develop over parts of the Central Appalachians.

The system will create significant impacts from heavy snow and wind. The
combination of heavy snow rates and gusty winds will lead to dangerous
travel conditions, with whiteout conditions and snow-covered roads. The
combination of wet snow, high snow load, and strong wind gusts could also
result in tree damage and power outages.

Moreover, prolonged onshore winds will continue through Thursday,
resulting in moderate coastal flooding for portions of the northern
Mid-Atlantic and Southern New England Coast. Impacts include widespread
roadway flooding, coastal and bayside flooding, impassable roads, and some
damage to vulnerable structures. Snow will linger over the Central
Appalachians through late Friday night, while the snow will linger over
parts of the Northeast from Friday into Saturday morning. The temperatures
will be 10 to 20 degrees below average over parts of the Ohio Valley.
Also, showers and thunderstorms could occur over parts of the Eastern Ohio
Valley through northern Mid-Atlantic on Thursday.

Meanwhile, a front over the Northern High Plains, Great Basin, and
Southern California will move eastward to the Northern/Central/Southern
High Plains by Saturday. The system will create coastal rain and
higher-elevation snow over parts of the Pacific Northwest/Northern
Intermountain Region and Northern California on Thursday morning,
expanding into Central/Southern California Thursday evening into Friday.
Heavy snow will develop over the Sierra Nevada Mountains on Thursday. The
snow will continue over the Northwest through Saturday. Moderate to heavy
snow will develop over the Northern Intermountain Region on Friday. The
snow will linger over the Sierra Nevada Mountains through Saturday, while
the snow moves into the Great Basin, Southwest, and Central/Southern
Rockies Friday evening into Saturday.

…Heavy snow over the Upper Great Lakes, Upstate New York, and Northern
New England on Wednesday; Heavy snow over the Sierra Nevada Mountains and
Central Appalachians on Thursday…

…There is a Slight Risk of excessive rainfall over parts of the
Mid-Atlantic and Southern New England on Wednesday…

…There is a Sight Risk of severe thunderstorms over parts of the
Mid-Atlantic Coast to the Southeast Coast and Florida peninsula on
Wednesday…

A deep storm over the Great Lakes will move southeastward to the
Mid-Atlantic Coast by Thursday evening and northeastward to the Gulf of
Maine by Friday. The system will produce a late-season winter storm across
portions of the Great Lakes and the Northeast from Wednesday into Friday.
The western portion of the Upper Peninsula of Michigan is forecast to
receive heavy snow through Wednesday evening. Snowfall accumulations of as
much as 1 to 2 feet are expected in parts of northern Wisconsin and the
western portion of the Upper Peninsula of Michigan.

The same storm will produce Northeast snow and wind Wednesday through
Friday. Heavy, wet snow and some sleet will spread into the Northeast on
Wednesday and continue into Friday. Portions of northern New York and
Northern New England will likely see significant snow accumulations of
over 12 inches.

The system will create significant impacts from heavy snow and wind, and
the combination of heavy snow rates and gusty winds will lead to dangerous
travel conditions, with whiteout conditions and snow-covered roads. The
combination of wet snow, high snow load, and strong wind gusts could also
result in tree damage and power outages. On Thursday, heavy snow will
develop over parts of the Central Appalachians.

Furthermore, prolonged onshore winds late Wednesday and continuing through
Thursday will result in moderate coastal flooding for portions of the
Northeast Coast. Impacts include widespread roadway flooding, coastal and
bayside flooding, impassable roads, and some damage to vulnerable
structures.

Moreover, along the associated front extending from the Lower Great Lakes
to the Central Appalachians southward to the Central Gulf Coast will move
off most of the East Coast overnight Wednesday. The boundary will aid in
producing showers, and severe thunderstorms will develop over parts of the
Mid-Atlantic and Southeast Coast. Therefore, the SPC has issued a Slight
Risk (level 2/5) of severe thunderstorms over parts of the Mid-Atlantic
Coast to the Southeast Coast and Florida peninsula through Thursday
morning. The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, hail, and a few tornadoes.

Showers and thunderstorms will produce heavy rain over parts of the
Mid-Atlantic and Northeast. Therefore, the WPC has issued a Slight Risk
(level 2/4) of severe thunderstorms over parts of the Mid-Atlantic and
Southern New England through Thursday morning. The associated heavy rain
will create mainly localized areas of flash flooding, with urban areas,
roads, and small streams the most vulnerable. The threat of severe
thunderstorms and excessive rainfall ends on Thursday.

Meanwhile, a front moving inland over the Pacific Northwest into Northern
California will move eastward to the Northern Rockies to the Great Basin
and Southwest by Friday. On Wednesday, the system will create coastal rain
and higher-elevation snow over parts of the Pacific Northwest/ Northern
Intermountain Region, moving inland to the Northern Intermountain Region,
Great Basin, and Northern California overnight. The snow levels will lower
after the front passes by over the Northwest. The coast/lower elevation
rain and higher elevation snow will continue over the Pacific
Northwest/Northern Intermountain Region through Friday.

On Thursday, rain and higher-elevation snow will move into Central
California and expand into the Great Basin. Overnight Thursday, rain will
move into Southern California. Heavy snow will develop over the Sierra
Nevada Mountains on Thursday into Friday.

…Heavy snow over the Upper Great Lakes/Upper Mississippi Valley on
Tuesday and Wednesday; Heavy snow over Upstate New York and Northern New
England on Wednesday…

…There is a Moderate Risk of severe thunderstorms over parts of the Ohio
Valleys on Tuesday and two areas of Slight Risk over parts of the
Mid-Atlantic and Florida peninsula on Wednesday…

…There is a Sight Risk of excessive rainfall over parts of the Lower
Great Lakes, Ohio/Tennessee Valleys, and Central Appalachians on Tuesday…

A deep storm over the Middle Mississippi and Ohio Valleys will move to
Southern New England by Thursday. The system will produce a large,
long-duration winter storm, producing gusty winds and late-season heavy
snow across portions of the Great Lakes and the Northeast from Tuesday
into Friday. The Upper Great Lakes are forecast to receive heavy snow.
Heavy snow will have a 60 to 70 percent likelihood of developing over
Wisconsin by Tuesday evening and expanding into the Upper Peninsula of
Michigan overnight Tuesday. Snow will continue over much of the region
through Wednesday, with additional heavy snow across the Upper Peninsula
of Michigan, before ending on Thursday.

The same storm will produce Northeast snow and wind Wednesday-Friday.
Secondary low-pressure development along the Mid-Atlantic coast will have
a 60 to 70 percent likelihood of bringing heavy, wet snow and some sleet
to the Northeast Wednesday afternoon through Friday. Significant snow
accumulations are likely over Upstate New York and Northern New England.
The system will create significant impacts from heavy snow and wind, and
the combination of heavy snow rates and gusty winds will create a 60 to 70
percent likelihood of hazardous travel due to low visibility and
snow-covered roads. The wet snow and high snow load may also damage trees
and impact infrastructure.

Moreover, along the associated front extending from the Mid-Atlantic to
the Ohio/Middle Mississippi Valleys, showers and severe thunderstorms will
develop over parts of the Ohio/Tennessee Valleys. Therefore, the SPC has
issued a Moderate Risk (level 4/5) of severe thunderstorms over parts of
the Ohio Valley through Wednesday morning. The hazards associated with
these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a few tornadoes. In addition, there is an increased
threat of EF2 � EF5 tornados over parts of the Ohio/Tennessee/Lower
Mississippi Valleys. Additionally, there is an increased threat of severe
thunderstorm wind gusts of 65 knots or greater over parts of the Ohio
Valley and a small portion of the Tennessee Valley. Further, there is an
increased threat of two-inch or greater hail over parts of the Ohio Valley.

The storms will also produce heavy rain. Therefore, the WPC has issued a
Slight Risk (level 2/4) of excessive rainfall over parts of the Lower
Great Lakes, Ohio/Tennessee Valleys, and Central Appalachians through
Wednesday morning. The associated heavy rain will create mainly localized
areas of flash flooding, with urban areas, roads, and small streams the
most vulnerable.

Showers and severe thunderstorms will develop over two areas as the front
moves across the Mid-Atlantic and parts of the Southeast. Therefore, the
SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over
parts of the Mid-Atlantic and a second area over the Florida peninsula
from Wednesday into Thursday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes.

However, the threat of excessive rainfall will be limited to a Marginal
Risk over parts of northern Mid-Atlantic and Southern New England from
Wednesday through Thursday morning.

Meanwhile, a front over the Eastern Pacific will move onshore over the
Pacific Northwest by late Tuesday afternoon and move eastward to the
Northern Rockies to the Great Basin and Southern California by Thursday.
The system will create coastal rain and higher-elevation snow moving
inland to the Northern Intermountain Region, Great Basin, and Northern
California overnight Wednesday into Thursday.

…Heavy snow over parts of the higher elevations of Wyoming, Nevada,
Colorado, Utah, and Arizona…

…There is a Sight Risk of excessive rainfall over parts of over parts of
the Middle Mississippi and Ohio Valleys on Monday…

…There is a Slight Risk of severe thunderstorms over parts of the Middle
Mississippi and Ohio Valleys on Sunday; there is an Enhanced Risk of
severe thunderstorms over parts of the Southern Plains, Middle
Mississippi, and Ohio Valleys on Monday…

A front extending from the Mid-Atlantic to the Central Plains will be
quasi-stationary through Monday morning. Moisture from the Western Gulf of
Mexico will pool along the boundary, creating showers and severe
thunderstorms over parts of the Middle Mississippi and Ohio Valleys.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Middle Mississippi and Ohio Valleys
through Monday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes. Farther east along the boundary, showers and thunderstorms will
develop over parts of the Central Appalachians and Mid-Atlantic on Sunday.

On Monday, the threat of severe thunderstorms increases over parts of the
Southern Plains, Middle Mississippi, and Ohio Valleys. Therefore, the SPC
has issued an Enhanced Risk (level 3/5) of severe thunderstorms over the
parts of the Southern Plains, Middle Mississippi, and Ohio Valleys from
Monday into Tuesday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes. Moreover, there is an increased threat of EF2
to EF5 tornados over parts of the Middle Mississippi Valley into the
Western Ohio Valley. In addition, there is an increased threat of hail two
inches or greater in size over parts of the Southern Plains/Middle
Mississippi Valley.

Furthermore, the showers and thunderstorms will produce heavy rain over
parts of the Middle Mississippi and Ohio Valleys. Therefore, the WPC has
issued a Slight Risk (level 2/4) of excessive rainfall over parts of the
Middle Mississippi and Ohio Valleys from Monday to Tuesday morning. The
associated heavy rain will create mainly localized areas of flash
flooding, with urban areas, roads, and small streams the most vulnerable.
Likewise, showers and thunderstorms will extend into the Central
Appalachian and Mid-Atlantic on Monday.

Meanwhile, the threat of excessive rainfall is a Marginal Risk over parts
of Southern California and Arizona on Sunday. The associated heavy rain
will create localized areas of flash flooding, affecting areas that
experience rapid runoff and burn scars. In addition, the moisture streamed
inland due to the upper-level low off the Southern California Coast will
aid in creating heavy snow over the higher elevations of Wyoming, Nevada,
Colorado, Utah, and Arizona through Monday. Moderate to heavy snow will
linger over parts of Utah, Arizona, Colorado, and New Mexico from Monday
evening into Tuesday. Rain will develop over lower elevations of the
Southwest and Southern Rockies, ending on Tuesday. Additionally, light to
moderate snow will develop over parts of the Northern/Central Plains on
Sunday. The snow will linger over the area on Monday and end overnight on
Monday.

…Heavy snow over parts of the Sierra Nevada Mountains and the higher
elevations of Wyoming, Nevada, Colorado, Utah, and Arizona…

…Snow over parts of the Upper Great Lakes…

…There is a Sight Risk of excessive rainfall over parts of Southern
California on Saturday…

An upper-level low will develop off the Central California Coast on
Saturday, moving inland to the Southwest by Monday. The circulation around
the low will stream moisture inland over parts of Southern California and
other parts of the West. Rain and higher-elevation snow will spread over
parts of California. The flow of moisture will create heavy rain over
parts of Southern California. Therefore, the WPC has issued a Slight Risk
(level 2/4) of excessive rainfall over parts of Southern California
through Sunday morning. The associated heavy rain will create mainly
localized areas of flash flooding, with urban areas, roads, small streams,
and burn scars the most vulnerable.

In addition, the moisture will aid in creating heavy snow over the Sierra
Nevada Mountains and the higher elevations of Wyoming, Nevada, Colorado,
Utah, and Arizona through Monday.

On Sunday, the threat of excessive rainfall decreases slightly to a
Moderate Risk over parts of Southern California and Arizona through Monday
morning. The associated heavy rain will create localized areas of flash
flooding, affecting areas that experience rapid runoff and burn scars.
Further, rain will continue over parts of Southeastern California and
Arizona through Monday.

Furthermore, low pressure over parts of the Middle Mississippi and Ohio
Valleys will move eastward off the northern Mid-Atlantic Coast by Sunday
morning. The energy will produce snow over the Upper Great Lakes through
Sunday morning. Additionally, showers and thunderstorms will develop over
the Middle Mississippi and Ohio Valleys through Monday. The SPC has issued
a Marginal Risk (level 1/5) of severe thunderstorms over parts of the
Middle Mississippi and Ohio Valleys through Monday morning. The hazards
associated with these thunderstorms are frequent lightning, strong to
severe thunderstorm wind gusts, hail, and a few tornadoes.

Elsewhere, low pressure over Eastern Canada will slowly move northeastward
farther into Canada by Saturday evening. Light snow will linger over parts
of Northern Maine through Saturday afternoon.

…Heavy snow over parts of the Sierra Nevada Mountains and the higher
elevations of Wyoming, Colorado, Utah, and Northern Maine…

…Light to moderate snow over parts of the Upper Midwest…

…There is a Sight Risk of excessive rainfall over parts of Southern
California on Friday and Saturday and Northern Maine on Friday…

An upper-level low will develop off the Northwest Coast and move southward
to off Southern California by Sunday. The circulation around the low will
stream moisture inland over parts of Southern California and other parts
of the West. Coastal rain will develop over parts of the Pacific
Northwest, and rain/higher-elevation snow will spread over parts of
California. By Friday afternoon, the flow of moisture will create heavy
rain over parts of Southern California. Therefore, the WPC has issued a
Slight Risk (level 2/4) of excessive rainfall over parts of Southern
California through Saturday morning. The associated heavy rain will create
mainly localized areas of flash flooding, with urban areas, roads, small
streams, and burn scars the most vulnerable.

In addition, the moisture will aid in creating heavy snow over the Sierra
Nevada Mountains and the higher elevations of Wyoming, Colorado, and Utah
through Sunday. Moreover, the heavy rain will continue over Southern
California on Saturday. Therefore, the WPC has issued a Slight Risk (level
2/4) of excessive rainfall over parts of Southern California on Saturday
through Sunday morning. The associated heavy rain will create mainly
localized areas of flash flooding, with urban areas, roads, small streams,
and burn scars the most vulnerable.

Furthermore, upper-level energy over the Northern Tier States will move
eastward across the Great Lakes into the Northeast by Sunday. The energy
will produce light to moderate snow over the Northern Tier States into the
Great Lakes through Sunday. Additionally, showers and thunderstorms will
develop over the Upper/Middle Mississippi Valley and Great Lakes/Ohio
Valley by Friday evening into Sunday. Along the rain/snow line, a few
pockets of light rain/freezing rain will develop over parts of the Upper
Mississippi Valley and Upper Great Lakes late Friday night into Saturday.

Meanwhile, low pressure off the Northeast Coast will move northward into
Eastern Canada by Saturday evening. Moisture will stream along the
Northeast Coast, creating heavy rain along the Maine Coast. Therefore, the
WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts
of the Maine Coast through Saturday morning. The associated heavy rain
will create mainly localized areas of flash flooding, with urban areas,
roads, and small streams the most vulnerable.

Further, the energy associated with the low will help produce heavy snow
over parts of Northern Maine through Saturday morning. Snow will linger
over Northern Maine through Sunday.

…Rainy, stormy weather continues along the East Coast through today,
lingering in New England Friday…

…Unsettled weather for the West, with a late season Atmospheric River
impacting California Friday…

…Warming trend begins over Central U.S. today…

Two slow moving frontal boundaries will continue to push towards the East
Coast today, with the leading front pushing into the Atlantic by early
afternoon and the second front slowing approaching the coast while
weakening through this evening. Chances for showers and thunderstorms will
continue through today along the East Coast but taper off from south to
north as the leading front exits. Locally heavy rainfall will be possible
over portions of the eastern Mid-Atlantic and coastal New England, which
may cause isolated to scattered instances of flash flooding. The highest
risk for flash flooding will be over eastern North Carolina and far
southeastern Virginia as a wave of low pressure moves along the frontal
boundary today, and there is a Slight Risk of Excessive Rainfall (level
2/4) for this area. Precipitation chances will likely linger through
Friday for portions of New England as low pressure strengthens just east
of the region. Colder air moving in from the north will allow rain to
switch to wintry mixed precipitation and snow overnight into Friday for
inland areas. Winds will also become gusty in the Northeast on Friday and
Saturday as the low strengthens and the pressure gradient tightens.

Meanwhile, a frontal system will push southeast across much of the West
with unsettled weather today into Friday. Mountain snow and low elevation
rain will impact the region, and locally heavy snow will be possible for
regional mountain ranges from the Pacific Northwest southward into
northern/central California, as well as for the eastern Great Basin into
the northern/central Rockies. Low pressure associated with the
southeastward moving frontal system will push into the northern and
central Plains on Friday and reach the Great Lakes region by Saturday
morning. This will bring chances for wintry precipitation to the Upper
Midwest and northern Great Lakes and chances for showers and thunderstorms
to portions of the Midwest and Ohio Valley.

On Friday afternoon, a Pacific low pressure system will approach the
California coast. This system will aim a plume of moisture (an atmospheric
river) at central and southern California Friday night into Saturday,
which will result in heavy rainfall and potentially flash flooding. There
is a Slight Risk of Excessive Rainfall (level 2/4) for portions of coastal
southern California on Friday and Saturday where upslope flow along
terrain will likely enhance rainfall totals and could lead to scattered
instances flooding.

Temperature-wise, lows this morning will be chilly, dropping into the low
to mid-30s across portions of the Mid-South into the Tennessee Valley
following a cold front passage, and Frost/Freeze-related advisories and
warnings are in place for newly greening sensitive vegetation. Increasing
upper-level ridging over will bring warmer, above average temperatures to
portions of the Central U.S. today, to the Plains, Mississippi Valley, and
Midwest on Friday, and to the Southeast and Mid-Atlantic on Saturday.
Below average high temperatures are forecast for much of the West through
the weekend due to expected cloud cover and precipitation and for the
northern high Plains Friday through the weekend as colder air moves in
behind a cold front.

…Rainy, stormy weather across the Southeast Coast through Thursday…

…Unsettled weather arrives over Northwest today…

…Warming trend begins over Central U.S. on Thursday…

A stalled out surface front along the Southeast Coast will be the focus
for heavy rain and thunderstorms through Thursday afternoon. There are
Slight Risks (at least 15%) of Excessive Rainfall leading to Flash
Flooding over parts of eastern North Carolina and southeast
Georgia/northern Florida today, where areas of surface low pressure along
the stationary front may enhance rainfall rates/totals. The Storm
Prediction Center has only a Marginal Risk (level 1/5) of Severe
Thunderstorms along the Southeast Coast today. Rain showers should develop
along the Mid-Atlantic and Northeast Coasts today along and ahead of a
northern stream cold front. There’s a Slight Risk of Excessive Rainfall
for portions of southeastern Virginia into northeastern North Carolina on
Thursday morning, right before the low pressure system and associated
precipitation push off into the Atlantic. Showers continue along the
Northeast Coast on Thursday with some potential snow showers developing
over interior portions of New England. Coastal low development along the
New England coast could also support some enhanced rain totals for
southern New England, in particular, by Friday morning.

Out West, a period of rainy/snowy weather will ensue across the Northwest
today. Precipitation will spread across the Pacific Northwest this morning
then into northern California and the interior Northwest this
afternoon/evening. Moderate to heavy snow is possible over parts of the
Cascades, Sierra Nevada and Northern Rockies; where between 1-2 feet of
snow may accumulate by Friday morning. Elsewhere, troughing along the lee
of the Rockies will promote southerly flow into the Great Plains beginning
Thursday. This pattern will support above average temperatures from the
Central/Southern Plains into the Midwest through the weekend.

…Winter Storm comes to an end over the Northern/Central Plains and Upper
Midwest; well below average temperatures over Great Plains…

…Severe Weather potential over parts of the Midwest and central Gulf
Coast today…

…Heavy to Excessive Rainfall possible over portions of the Southeast and
Mid-Atlantic…

…Unsettled weather returns to the Northwest on Wednesday…

Heavy snow and blizzard conditions associated with a deep mid-latitude
cyclone impacting the Northern/Central Plains and Upper Midwest will come
to an end today. Additional snowfall accumulations of 2-4 inches are
expected across eastern Minnesota by Wednesday morning, when the system is
forecast to move into Ontario/southern Canada. A frigid airmass will
continue to spread across the Great Plains today and Wednesday behind a
cold front. Highs will be 15-25 degrees below average for much of the
Plains today. Temperatures will moderate later this week.

Rain showers and scattered to isolated thunderstorm activity are likely
east of the Mississippi River today. Storms will organize along a pair of
cold fronts associated with two separate low pressure systems; the Upper
Midwest system and the Gulf Coast system. The Storm Prediction Center
issued a Slight Risk of Severe Thunderstorms (level 2/5) for parts of the
southern Great Lakes and for portions of the Gulf Coast today. Damaging
wind gusts will be the main threat for both areas, but a brief tornado
can’t be ruled out over the Gulf Coast. The Gulf system is forecasted to
stall out over the Southeast/Florida panhandle this afternoon/evening
leading to potentially heavy rainfall occurring particularly over the
Florida panhandle. Significant moisture return from the Gulf will interact
with the slow moving cold front, which will produce an axis of 2-4 inches
of rain from northern Florida through the Southeast coast on Wednesday. A
Slight Risk (at least 15%) of Excessive Rainfall leading to Flash Flooding
is in effect for parts of north-central Florida into southern Georgia.

A deep low pressure system will bring another round of unsettled weather
to the Northwest beginning on Wednesday. Low elevation rain and mountain
snow are expected from this system. Accumulating snow should remain
confined to the higher elevations of the Cascades, Sierra Nevada and
Northern Rockies. Some 1-2 inch 24 hour rainfall totals pose a Marginal
Risk (at least 5%) of Excessive Rainfall leading to Flash Flooding over
parts of the northern California into southern Oregon coastline.
