Widespread precipitation will continue today through Wednesday morning. Rainfall amounts over an inch are possible across parts of northeast Wyoming into western South Dakota. Temperatures will be cold enough for snow across the Black Hills. Rain will also change over to snow today across northeastern Wyoming. Snow fall amounts will range from 8" to 15" for the higher elevations of the northern Black Hills and Bear Lodge Mountains and 2" to 6" for the plains of northeastern Wyoming. The higher terrain of southern Campbell County will see up to 9" of accumulation. The northern foothills (Spearfish/Whitewood areas) will see 1" to 4" with up to 7" in the higher elevations and the central Black Hills will see 3" to 7". It's important to remember that minor changes in temperatures and elevation will determine how much snow accumulates.
The plains of western South Dakota should stay warm enough for rain through the event. However, it will only take a slight drop in temperatures tonight across northwestern South Dakota and the Rapid City area to get minor snow accumulations.
