...Unseasonably cold airmass threatens temperature records across the Deep
South, Lower Mid-Atlantic, and Florida Peninsula through tomorrow...

...Snow still expected across the Great Lakes, interior New England, and
west slopes of the Appalachians...

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

A highly amplified upper-trough centered near the Ohio Valley will
maintain an influx of unseasonably cold continental polar air, which is
forecast to threaten many temperature records over the Deep South, Lower
Mid-Atlantic, and Florida Peninsula through tomorrow. Accordingly, a swath
of Freeze Warnings and Cold Weather Advisories extend across these areas
where temperatures should be on average 20-30 degrees below normal.
Meanwhile, fire weather concerns across the Southeast and Northern Gulf
Coast should wane this evening with the approach of the surface high
pressure center, before shifting into the Southern Plains tomorrow amid
dry downsloping winds.

The northwesterly flow supplying cold air across the Midwest and interior
Northeast will also generate snowfall for portions of the Great Lakes and
Appalachians today, where an additional 4-8" are expected with isolated
higher amounts possible by Wednesday morning. Lake Effect Snow Warnings
remain in effect downwind of Lake Erie, while Winter Storm Warnings and
Winter Weather Advisories dot downwind areas of the Great Lakes, northern
Maine and the Central/Southern Appalachians. In the West, a low pressure
system is still on track to usher in an atmospheric river centered over
Southern Oregon and Northern/Central California late Wednesday, although
much of the precipitation looks to fall beyond the forecast period. While
forecast specifics will become more apparent in the coming day, users are
encouraged to stay tuned as isolated flooding and heavy elevation snowfall
are possible with this upcoming system.
