Winter will not give up, warns the Weather Service. Record cold temperatures are possible from the Upper Mississippi Valley into portions of the Plains…the mid section of the nation.

Temperatures will be 10 to 30 degrees below average across much of the central and eastern United States.

Meanwhile, heavy snow is likely over parts of the Northern/Central Rockies…

Heavy snow to blanket the region

As this system exits into the eastern Atlantic tonight showers and wet snowflakes will overspread the central/southern Appalachians, as well as the Mid-Atlantic states. Across the northern and central Rockies, winter will not give up as cold temperatures and heavy snow blanket the region.

A cold front is forecast to enter from Canada tonight and swing through the western U.S. Wednesday and Thursday. 1 to 2 feet of snow is possible across the higher elevations of Montana, Wyoming and Colorado.

Upwards of 6 inches of snow (15 cm) is forecast across the High Plains of Wyoming and northern Colorado. Snow showers are also possible across the Central Plains and Lower Great Lakes along the front.

Will feel more like March instead of mid-April

Temperatures across much of the central and eastern U.S. will feel more like March instead of mid-April. Thus, widespread Freeze Warnings and Frost Advisories stretch from the Southern Plains to the Ohio Valley. The core of the cold air will be found across the Midwest and Northern Plains through Thursday. High temperatures will struggle to get out of the 30s and 40s in this region, with lows in the teens and 20s.

Temperature records could fall

A few daily temperature records could fall here. Meanwhile, the West Coast and southern Florida will enjoy above average temperatures. Forecast lows in the 70s across southern Florida would break a plethora of daily high minimum temperature records.
