We have one more mild day in the forecast before things take a bit of a turn just ahead of the weekend. Today will be cloudy but still mild. High temperatures will range from the low 50s in Sioux Falls to the 40s across central and northern South Dakota.
Our next system will arrive later today and tonight. In Sioux Falls, rain will develop late this afternoon or this evening and continue through much of the night. By 2 or 3 am, rain will mix with and then eventually change to light snow with areas of light snow hanging on through daybreak tomorrow. Rainfall amounts of up to a quarter inch will be possible with lighter amounts north and west of Sioux Falls. Heavier rain is likely south and east of the Sioux Falls area. Locations along Highway 60 from Windom to Worthington to Sioux City could get between a quarter and a half inch of rain. Overall snow accumulation will depend on when rain changes to snow, but generally amounts will be light.
The system will impact central and northern South Dakota a bit earlier, but precipitation amounts will be lighter. Areas of light rain or drizzle are likely from Aberdeen to Pierre by mid to late afternoon today. As temperatures fall this evening, freezing drizzle and light snow will develop. Precipitation amounts will be light - generally a few hundredths of an inch. Areas of light snow and freezing drizzle will likely make roads and surfaces slippery across central and northern South Dakota this evening through tomorrow morning.
This system will be followed by a blast of cold air that will stick around for at least a couple of days. While clouds will break and the sun will come out rather quickly tomorrow morning, it will be cold and blustery. Thursday temps will be stuck in the low 30s with a gusty northwest wind. The wind will make it feel like it's in the teens for most of the day Thursday.
The good news is that we will bounce back to a pretty nice weekend. Saturday and Sunday will be mostly sunny with highs in the low 40 Saturday, climbing to the mid to upper 40s on Sunday.
