Accumulations of 3 to 6 inches (locally up to 8 inches) are possible along the path of this latest winter storm. Cities included are Omaha, NE, Kansas City, MO, Des Moines, IA, Moline, IL, St. Louis, MO, and Indianapolis, IN.

Behind the snow, strong winds gusting between 30 and 40 mph will develop through the Plains by tonight and spread eastward to the near the Mississippi River Thursday.

Farther east, highs will range from the 0s and 10s in the upper-Mississippi Valley to the 20s in the Great Lakes and Ohio Valley.
By Friday morning, lows from Kansas and western Missouri northward to the Dakotas and Minnesota will be below zero. The coldest readings, -20s and -30s, are expected in the Dakotas and northern Minnesota.
