...Unseasonably cold along the Southeast Coast and Florida today;
Central U.S. warms up...

...Snow expected to continue across Lower Great Lakes and interior
Northeast/New England...

...Atmospheric river to bring heavy rainfall and mountain snow to
the West Coast late Wednesday...


Upper troughing over the Eastern U.S. will continue to direct cold
continental polar air down into the Southeast today. High
temperatures in the 40s, 50s and 60s from the Florida Peninsula up
along the Southeast Coast will represent 20-30 degree temperatures
anomalies. These well below average high temperatures may threaten
many existing records today. Temperatures will begin to moderate
across the East on Wednesday when the upper low lifts out of the
region and into into eastern Canada. In the meantime, Lake effect
snow is expected to continue impacting downwind areas of Lakes
Erie and Ontario as well as parts of the Northern Appalachians.
Between 4-8 inches are likely over the aforementioned areas by
Thursday morning. Winter weather advisories and Lake effect snow
warnings are in effect.

In the West, a deep upper-level trough will bring substantial
moisture to the West Coast beginning on Wednesday night. Moderate
to heavy rain is expected along the California Coast between
Wednesday and Thursday, while the heaviest snow is anticipated to
occur over the Sierra on Thursday. Winter Storm Watches are in
effect for the Sierra beginning late Wednesday night and
continuing through early Friday morning. There`s a marginal risk
(at least 5% chance) of excessive rainfall leading to flash
flooding over portions of northern California on Wednesday night.
