CHAPPELL - Heavy snow is possible across portions of western and north-central Nebraska this week, according to the National Weather Service office in North Platte. 

There is still uncertainty in the track of this system which could impact where the heaviest snowfall occurs, but the weather service says four to eight inches could be possible in Sidney, Kimball, Bridgeport, Chappell, Big Springs, Ogallala, and Pine Bluffs. Five to 10 inches of snow is forecast for Sterling and Julesburg.

A winter storm watch is in effect from Tuesday evening through Wednesday evening for Cheyenne, Kimball, Banner, Morrill, Garden, Deuel, Keith, Perkins, Chase, Logan, Sedgwick, Phillips, and eastern Laramie Counties. The watch extends into central and southwest Nebraska.

The NWS says travel could become very difficult, especially morning and evening commutes on Wednesday. Northeast winds becoming northerly could gust up to 30 mph and cause some blowing and drifting snow.
