...Snow for the Northern Cascades and Northern Intermountain
Region/Northern Rockies...

...Temperatures will be 10 to 25 degrees below average over the Western
/Central Gulf Coast...

...Rain/freezing rain over parts of Washington State on Tuesday...

Upper-level impulses will produce lingering light snow over parts of
Northern New England and the Upper Great Lakes through Wednesday.
Meanwhile, a front over the Northern Pacific will move onshore over the
Northwest on Tuesday, moving to the Northern Plains by Wednesday evening.
The system will produce light rain and higher-elevation snow over the
Pacific Northwest on Tuesday morning, becoming more scattered by Tuesday
evening. The combination of snow and ice may cause hazardous road
conditions through tonight in this region. As the warm air moves inland
over Washington State, rain/freezing rain will develop over parts of
Central Washington State. Overnight Tuesday, snow moves into the Northern
Intermountain Region/Northern Rockies into Wednesday. Moreover, the Air
Stagnation Advisories will end on Monday afternoon as the approaching
system stirs the air.

Elsewhere, the upper-level energy over the Southern Plains will move
eastward off the Southeast Coast by late Tuesday evening. As a result, the
energy will produce light rain over parts of the Southern Plains/Western
Gulf Coast through Wednesday. In addition, weak upper-level impulses and
onshore flow will produce light rain and embedded thunderstorms over parts
of Florida from Tuesday into Wednesday. Furthermore, cold high pressure
and upper-level energy will aid in keeping temperatures 10 to 20 degrees
below average over the Southern Plains into the Western/Central Gulf Coast
through Wednesday.
