…Heavy snow for the Upper Peninsula of Michigan and the northern Lower
Peninsula on Wednesday…

…Heavy lake-enhanced snow downwind from Lakes Erie and Ontario on
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.

A slow-moving front across Florida will aid in creating showers and
thunderstorms over parts of the Central Gulf Coast to Florida on Friday.
After the boundary moves south of Florida, scattered light rain will
develop along the east coast of the Florida peninsula on Saturday. An area
of high pressure over Central Canada will usher cold air over parts of the
Northern Plains, bringing temperatures of 10 to 25 degrees below average.
The cold air has prompted Cold Weather Advisories over parts of North
Dakota on Friday morning.

In addition, upper-level troughing over the Great Lakes into the Northeast
and cold air streaming over the Great Lakes will produce heavy lake-effect
snow over the Upper Peninsula of Michigan through Sunday. Lighter snowfall
will develop over most of the west coast of the Lower Peninsula of
Michigan during the time period. However, heavy lake-effect snow will
develop over the parts of the northern Lower Peninsula of Michigan.
Moreover, heavy lake-effect snow will develop downwind of Lakes Erie and
Ontario through Sunday.

A quasi-stationary front extending from the Middle Mississippi Valley to
the Northern Rockies/Northern High Plains will be the focus for light snow
over parts of the Northern High Plains on Friday and over parts of the
Northern Plains on Saturday.

Furthermore, a wave of low pressure will develop on the boundary over
parts of the Central Plains and move eastward to the Central Appalachians
by Sunday. The system will produce light to moderate snow over parts of
the Middle Mississippi Valley eastward to the Central Appalachians on
Saturday into Sunday morning.

…Thanksgiving Day storm to push into the Northeast today spreading
rainfall and New England snowfall in its vicinity…

…Increasingly below average temperatures spill out into the Great Plains
and Mississippi Valley through the end of the week…

…Lake Effect snows continue and will expand and intensify with time…

A dynamic mid-latitude cyclone tracks near the New England coast today.
Scattered showers and thunderstorms spread into the East Coast today. A
swath of moderate to heavy snowfall is likely to develop across portions
of the interior Northeast — winter storm watches and warnings are in
effect for portions of central New England related to the heavy snow
threat.

Elsewhere, Lake Effect snow showers across the Upper Great Lakes may yield
anywhere from 4-8 inches over the northern coastline of the Upper
Peninsula of Michigan as well as northern parts of the Lower Peninsula
today. A disturbance aloft will allow for the development of a new cold
front late today which moves east and south ahead of a strong and cold
surface high. In the wake of this front, as temperatures cool further,
lake effect snows should expand and intensify as they interact with record
warm Great Lakes temperatures for late November. Several additional inches
of snow are forecast on Friday bringing 2 day snowfall totals over a foot
with isolated higher amounts possible across downwind areas of the Great
Lakes by Saturday morning. Florida will remain mild to warm.

…Heavy snow over parts of the Sierra Nevada Mountains, Great Lakes and
Central Rockies…

…Below average temperatures in the Plains…

A moderate level atmospheric river event will accompany a surface low
pressure system as it moves into the West today. This AR will spread
anomalous moisture over southern/central California, the Great Basin and
Central Rockies. Heavy coastal and mountain rain may lead to instances of
flash flooding, particularly over the windward foothills of the southern
Sierra Nevada below 8000 feet, where excessive rainfall may cause
land/rock/mudslides. Heavy snow accumulating between 1-3 feet are possible
over the higher elevations of the southern Sierra, as well as much of the
Intermountain West and Central Rockies today. Snow diminishes over the
Sierra on Wednesday while snow showers persist over the Colorado Rockies.
Snow showers continue across the Great Lakes this week with parts of the
Upper Peninsula of Michigan and downwind areas of Lake Ontario picking up
between 4-8 inches of snow by Thursday morning.

Troughing across the northern tier states will continue to promote below
average temperatures over the next several days. High temperatures in the
teens and 20s will represent a 15-25 degree departure from normal for much
of the far Northern Plains today and Wednesday. A pair of mid-level
disturbances are expected to phase over the Central U.S. and facilitate an
arctic outbreak across the region Wednesday night into Thanksgiving
Thursday.

…Heavy snow over parts of the Sierra Nevada Mountains, Upper Great Lakes
and Central Rockies…

…Below average temperatures in the Northern Plains; above average temps
in the Southern Plains/Lower Mississippi Valley today...

An upper-level trough will swoop into the West Coast from the northeast
Pacific early this week. This trough will direct a very anomalous
subtropical moisture plume along its base at central and southern
California today and Tuesday. A surface low pressure system will help
focus the anomalous moisture over coastal areas as well as the Sierra
Nevada. Parts of the southern Sierra below about 8000 feet may experience
instances of Flash Flooding today. Rock/mud slides and general debris flow
are some of the possible impacts from excessive rainfall in mountainous
areas. Heavy snow is probable at the higher elevations of the southern
Sierra, where 3-4 feet are forecast to accumulate with isolated higher
amounts possible by Wednesday morning. The anomalous moisture feed is also
expected to penetrate into the interior of the West. Parts of the Great
Basin will experience snow showers while heavy snow blankets the
Intermountain West and Colorado Rockies with 1-2′ (isolated 3′) likely
over the next couple of days.

Elsewhere, a pair of low pressure systems moving through the Upper
Midwest/Great Lakes will generate several inches of snow over the Upper
Peninsula of Michigan, while snow showers occur across the greater Upper
Midwest and Lower Great Lakes. Temperatures will remain above average for
one last day from the Southern Plains into the Midwest before a strong
cold front pushes through on Tuesday. Some record high temperatures (in
the mid to upper 80s) might be set over south Texas today. Highs topping
out in the teens and 20s will represent a negative 20-30 degree departure
from normal for parts of the Northern Plains today. Mild conditions
continue over much of the East Coast through Tuesday.

…Heavy Snowfall for parts of the Sierra Nevada…

…Above average temperatures spread from the central U.S. into the East
while cold airmass descends into the Great Plains…

A weak low pressure system will continue directing a plume of moisture at
the West Coast over the next few days. This will likely result in coastal
and low elevation rain, while moderate to heavy snow proliferates across
the coastal ranges of Washington, Oregon and California. The heaviest
snowfall is likely to occur over portions of the Sierra Nevada, with the
southern Sierra poised to accumulate 2-3 feet with isolated higher
amounts. Snow showers will also impact the Colorado Rockies over the next
few days. Heavy rain and snow chances increase on Tuesday as another
atmospheric river event arrives across parts of central California.

Relatively zonal flow across the southern tier of the country will support
another day of above average temperatures for the Central/Southern U.S.
today. An upper trough will pickup steam over the northern tier and send a
strong cold front diving south through the Great Plains over the next 48
hours. Highs in the teens will represent 20-30 degree departures from
normal over the Northern High Plains through Monday. Temperatures will
drop precipitously, from highs in 60s and 70s today to 40s and 50s on
Monday over parts of the Southern Plains as the cold front propagates
through. The associated warm front will spread mild air across the Eastern
U.S. on Monday before the cold front arrives and drops temperatures for
the rest of the week.

…Very strong Atmospheric River to produce heavy snow across the Sierra
Nevada before winding down over north/central California today…

…Above average temperatures expand across the Central U.S. this
weekend…

Moisture associated with a highly impactful and dangerous atmospheric
river event will diminish as it sags south and east through central
California today. Heavy snow is likely over much of the Sierra Nevada this
morning where anywhere between 1-2 feet are expected to accumulate when
all said and done. Upslope portions of the Sierra below 7000 feet may
experience isolated instances of flash flooding this morning before snow
levels drop on the backside of the cold front pushing through the West
this afternoon. Snow showers spread into Northern/Central Rockies this
afternoon and the Intermountain West on Sunday. Snowfall totals of 6-12
inches are probable for the aforementioned areas by the end of the weekend.

Surface high pressure extending from central Canada down to the Gulf Coast
will support below average temperatures for those regions through tonight.
Parts of the Southeast will experience low temperatures in the mid to
upper 30s which may lead to some frost/freezes. A deepening upper trough
over the north-central U.S.and Ridge over Mexico will promote above
average temperatures across the Great Plains today and Sunday before
expanding into the East by Monday. Elsewhere, mixed precipitation can be
expected to continue across portions of upstate New York and New England
today.
