Moisture To Return Across The Region

Areas of snow are expected to develop across parts of western and north central Nebraska tonight.  Areas of rain this afternoon will change over to snow this evening.  Accumulating snow is likely over the Nebraska Panhandle, as well as the northern and western Nebraska Sandhills, and far southwestern Nebraska.  The best chances for any accumulating snow will be along or west of a line from Valentine, through Ogallala and Grant. For Ainsworth, Broken Bow, North Platte and O'Neill - rain or a mixture of rain and snow are anticipated with little if any snowfall accumulation.

Later today upper level energy and southwest winds aloft will allow warmer air in the mid atmosphere to overrun a shallow dome of cold air near the surface.  Upslope conditions are expected east of the Continental Divide.  Widespread areas of 4 to 8 inches of snow will be possible across much of central Wyoming, into the Black Hills and North Central Colorado, as the upper disturbance moves into the Colorado Rockies. By Tuesday night, precipitation is expected to change over to snow across the high plains of western Nebraska, eastern Wyoming and northeastern Colorado.  As the upper level trough of low pressure swings across the north central Plains by Wednesday morning, a brief period of snow is possible, with light accumulations to the north and west of the track of the low pressure aloft.  This could bring some very light snow into western and central Nebraska, into early Wednesday.
