Snow Accumulation for Friday

Potential for Snow from the Rockies into the Central Plains on Saturday
An area of low pressure is forecast to develop in the lee of the Rockies and track eastward across the Southern Plains on Saturday. As this occurs, warm moist air is forecast to move northward ahead of the cold front associated with the low. This will result in widespread freezing rain and snow. Snow accumulations will range 3-6 inches with locally higher amounts in excess of 10 inches. In addition, the low will be intensifying over the Southern Plains, resulting in gusty winds Saturday night into Sunday. This will result in the potential for blowing and drifting snow. Wind chills will be as low as -20°F in some places.

Major Cities in Region: Cheyenne, WY, North Platte, NE, Omaha, NE

Thunderstorms Saturday for the Arklatex Region
As an area of low pressure develops in the Southern Plains and quickly tracks eastward toward the Tennessee Valley Saturday afternoon and evening, southerly flow will bring moist air northward. In addition, wind shear will increase across the region during the late afternoon and early evening. With these conditions in place, thunderstorms are expected to develop, some of which may become strong to severe. Damaging winds and large hail will be the primary hazards with the strongest storms. 

Major Cities in Region: Texarkana, AR, El Dorado, AR, Little Rock, AR
