Across western portions of South Dakota, snow accumulations of 2-5 inches with locally higher amounts in excess of 6 inches and wind gusts 50-65 mph will lead to blizzard conditions. Across central South Dakota, snow accumulations of 5-10 inches with locally higher amounts in excess of a foot are expected, in addition to ice accumulations less than 0.15 inch. Across eastern South Dakota, 3-7 inches of snow and ice accumulations up to 0.05 inch are forecast. 

In northern Nebraska, snowfall accumulations of 2-4 inches with locally higher amounts in excess of 6 inches are forecast, in addition to ice accumulations up to 0.10 inch. Winds 40-50 mph will allow for blowing snow and reduced visibilities.

Central and eastern Minnesota will get 6-10 inches of snow with locally higher amounts in excess of a foot are expected. Ice accumulations will be less than 0.15 inch. Across southern Minnesota, 4-8 inches with locally higher amounts in excess of 10 inches are expected in addition to ice accumulations up to a tenth of an inch. Winds gusting 30-40 mph will allow for blowing snow and reduced visibilities. In southern Minnesota and northern Iowa, snow accumulations will range 3-5 inches. Ice accumulations up to 0.10 inch are forecast. 

For western Wisconsin, 6-10 inches with locally higher amounts in excess of a foot are expected through Tuesday evening. Across Central and eastern Wisconsin, snowfall totals will range 4-8 inches.

Region 1

Thunderstorms Monday from East Texas into Mississippi
The cold front associated with an area of low pressure in the Upper Midwest will stretch to the south over southeast Texas, Louisiana, and Mississippi. Clouds may limit instability, but with moisture in place and the upper level environment, thunderstorms may develop during the afternoon. Gusty winds and large hail will be the primary hazards. Activity will diminish after sunset.

Region 2

Dense Fog along the Texas Coast through Tuesday Evening
Fog will continue along the Texas and Louisiana coasts through Tuesday evening. Visibilities will be less than a mile at times before a cold front moves through the region.

Winter Storm Potential for the Northeast Wednesday into Thursday Morning
Rain will begin to transition to snow across portions of the Northeast Wednesday morning as a strong area of low pressure develops off the coast. This area of low pressure is forecast to rapidly develop while moving northeastward, with the potential for moderate to heavy snow north and northwest of the center of the low. Snow accumulations will range 6-10 inches with locally higher amounts in excess of a foot from eastern New York eastward to Connecticut. Across southeastern Pennsylvania into northern New Jersey, snow accumulations of 3-5 inches with locally higher amounts in excess of 7 inches are expected.
