National Weather Service Doppler Radar indicated an arcing band of moderate to heavy snow to the northeast of the surface low from east-central Colorado east into northwest Kansas and southward into southwest Kansas. Another band of light to moderate snow extended eastward through southern Nebraska, with additional areas of light snow to the southwest into the Oklahoma and Texas Panhandles. In addition to the snow, very cold temperatures followed in the air mass to the north of the front across the Plains, Rockies, and into the Southwest.

Snow currently over the Central High Plains will begin to taper off through the evening and overnight hours Wednesday. The system will continue to produce rain, thunderstorms, a wintry mix, and snow across central and eastern portions of the country as it moves to the east. Warm, moist air will flow northward from the Gulf of Mexico ahead of the cold front. Severe weather and heavy rainfall, including some isolated to scattered instances of flash flooding, will be possible with the storms ahead of the front. The flow of moisture will also persist around to the north and west of the surface low over the colder air mass to the north, helping to continue a swath of moderate to heavy snow from the Central Plains northeastward through the Middle Missouri Valley, Upper Mississippi Valley, and into the Lower Great Lakes. Snowfall totals will generally range between 4-8 inches, with some locally higher amounts possible. Uncertainty in amounts increases further to the northeast over the Lower Great Lakes, though snow is still expected. Snowfall rates may approach a heavy 1-2" per hour at times. Gusty northerly winds will lead to some areas of blowing snow, including for locations where the snowfall has or will soon end. In addition, a wintry mix of rain, freezing rain, sleet, and snow is expected to the south of the snowfall axis, particularly from northern Missouri into northern Illinois. Bitterly cold wind chills will continue through Wednesday night for portions of southern Wyoming, where temperatures may feel as cold as 25 below for some locations. The next Storm Summary will be issued by the Weather Prediction Center at 900 AM CST. Please refer to your local National Weather Service office for additional information on this event. Putnam $$
