Another southward-diving push of Canadian air will nose its way through the Northern Tier as a potent winter storm spins across the southern Plains. This will bring heavy snow to the central Plains while showers and thunderstorms cover much of the lower Mississippi Valley.
WeatherBug Meteorologist Todd Nelson has the latest in this exclusive WeatherBug National Outlook.
The cold air will help keep all of the northward moving moisture in the form of snow for the central Plains and eastern Rockies. Some locations in Nebraska and Kansas and will see more than a foot of snow by Thursday night. For more on this winter storm, click on this story
Along the southern fringes of the storm, an icy mess will fall from northern Oklahoma to St. Louis and especially in north-central Arkansas. Farther south, rain will occur across the southern Plains and Lower Mississippi Valley. This system will be dynamic enough to bring the chance for severe thunderstorms with damaging winds and even tornadoes to parts of the Gulf Coast.
High temperatures across the region will range from the teens and 20s in the Upper Midwest, 30s and 40s in the central Plains and central Mississippi Valley, to the milder 50s and 60s in the Lower Mississippi Valley. It will be breezy as well along the southern Front Range and into the Panhandles of Texas and Oklahoma.
Heading East, some snow and snow showers will fall in the eastern Great Lakes, the central Appalachians, and in northern New England. It will be a rather cool day, with highs in the 20s and 30s across most of the Northeast. The Mid-Atlantic will warm into the 30s and 40s, while the Southeast hits the 50s and 60s. Along the Gulf Coast and into Florida, high will range from the 60s to the lower 80s, with mostly sunny skies expected.
In the West, coastal showers and inland snow will once again fall in the Pacific Northwest. Sunshine will be the rule in California and the Southwest. Highs will mainly hit the middle 40s in the coastal Northwest, with 20s and 30s in the higher elevations of the Great Basin. Temperatures will warm to the mid-to-upper 50s in northern California, with highs in the rather-cool upper 50s and lower 60s in Los Angeles and Phoenix.
