SUNDAY WEATHER SYSTEM TO BRING RAIN AND SNOW
Things start to turn through the day Sunday. Snow will begin to fall over far northern and northwestern Nebraska overnight Saturday in to Sunday. The band of snow will spread south/southeast throughout the day. Once the precipitation reaches I-80, areas south of the interstate should start out as rain before changing over to snow later in the day/evening.
There remains some question as to how quickly the precipitation reaches the ground south of I-80. High resolution computer models suggest there could be a shallow layer of dry air (below 3,000ft). That means as precipitation falls in to the layer, it will evaporate. Once this air mass becomes saturated the precipitation can reach the ground. It could take a few hours for this to happen.
The snow forecast is being worked on. It does appear areas north of I-80 will see higher amounts compared to areas south of the interstate. Places like Valentine and O’Neill have the potential of receiving 6″-8″ of snow through Monday morning. Whereas places like Lincoln may be on the order of 2″-4″.
