...Persistent rain and higher elevation snow chances for the Pacific
Northwest and Rockies...

...Storm system to bring rain, thunderstorms, and a wintry mix to the
eastern half of the country....

...Seasonably warm weather forecast for the East and South, with elevated
fire weather conditions for portions of the Southern Plains Wednesday...

Rain and higher elevation snow showers will continue for the Central and
Northern Rockies as a storm system continues through the region.
Accumulations should generally remain light overall. However, some of the
mountains in southwestern Montana, northwestern Wyoming, and north-central
Colorado will see a few inches of snow through Wednesday morning.
Meanwhile, another series of storm systems will begin to impact the
Pacific Northwest Wednesday into Thursday bringing additional heavy rain
and mountain snow as an atmospheric river helps usher in increased
moisture across the region. A Marginal Risk of Excessive Rainfall is in
effect Thursday for the chance of 1-3 + inches of rain and rain rates
potentially exceeding 0.5 inches per hour.

A few lingering showers may continue along a frontal boundary from the
Northeast southwest through the Southern Plains overnight Tuesday into
Wednesday. However, precipitation will increase significantly as the storm
system currently moving through the Rockies continues into the Plains
Wednesday and intensifies as it moves east across the country. Widespread
rain and thunderstorms are likely ahead of a cold front moving into the
Midwest and Southern Plains Wednesday and sweeping eastward into the Great
Lakes, Ohio Valley, and Southeast on Thursday. A warm front moving up the
East Coast will also help increase rain and thunderstorm chances for the
Carolinas and Mid-Atlantic on Thursday. Colder air surging southward on
the back side of the system will lead to a wintry mix of rain and snow for
the Northern Plains and Midwest Wednesday night into Thursday.

Ahead of the cold front, seasonably warm high temperatures are forecast
for the East and South. Highs on Wednesday and Thursday will generally be
in the 50s and 60s in the Northeast and Midwest, the 70s in the Southeast,
and into the 80s for Texas, all around 5-10 degrees above normal. The warm
weather will continue ahead of the front for the East on Thursday as
temperatures behind the front drop into the 40s in the Upper Midwest, 50s
in the Central Plains, and 60s in the Southern Plains. In addition to the
seasonably warm temperatures, dry and breezy conditions ahead of the cold
front across southeastern New Mexico and southwest Texas have prompted an
Elevated Risk of fire weather from the Storm Prediction Center for
Wednesday.
