Heavy Rain in the Southeast; Wintry Mix from the Plains through the Ohio Valley

A storm system will bring a number impacts to the central and eastern US. Heavy rain and thunderstorms are expected in the Gulf Coast and Deep South. Further north, a wintry mix may produce a glaze of ice from the Ozarks/Mid-South east through the Ohio Valley. Accumulating snow is expected from the central Plains east into the Upper Ohio Valley/Lower Great Lakes. Read More >

A warm front will move through northeastern Wyoming and western South Dakota today leading to breezy west to northwest winds at times as well as milder temperatures. The milder temperatures will last until Tuesday, but then a cold front will move through late Tuesday bringing much colder temperatures for Wednesday.
As the cold front moves through late Tuesday, some light precipitation will occur on the plains. Light snow is mostly expected in the west, but east of the Black Hills light rain mix in Tuesday afternoon. The best chance for accumulating snow will be for the northern Black Hills where upslope-enhanced snowfall is expected.
In case you were wondering, meteorological winter officially starts today (December 1). Yeah, mother nature brought winter last week, but it is always a good idea to (re)review winter weather safety. Surf to weather.gov/winter for details.
