We’ve had a mostly sunny and warm day across the KELOLAND region. Temperatures have been above-normal, in the 40s in northern KELOLAND and the 50s in the south. Winds have turned to an easterly direction, so clouds have started to thicken overhead.
Tonight skies will be partly to mostly cloudy. East winds will increase in speed to 15-25 mph. Rain showers will start to move into western and central South Dakota. Lows will be mild – near or above freezing.
Tomorrow will be a cloudy and very rainy day. Rainfall totals could be in the range of ¼” to ¾”, so it could be a soaker. High temperatures will be in the upper 30s to low 40s East River, but the 50s to low 60s in the west. There will be a brisk easterly wind 15-25+ mph.
There is the potential for hazardous weather tomorrow in NE South Dakota across to western and southwestern Minnesota. A Winter Storm Warning is posted for that area. Lesser amounts of snow are likely in Aberdeen and Watertown, which are under a Winter Weather Advisory. The potential is there for both accumulating snow, and freezing rain that could coat trees, powerlines, and surfaces. The warning and advisory are in effect from tomorrow morning to Saturday morning.
We’ll continue with the rainfall chances in eastern KELOLAND through the morning hours on Saturday, ending during the afternoon. We will still have considerable cloud cover, and temperatures will remain cool, in the upper 30s to low 40s East River. West River will be a little warmer, in the 40s and 50s.
There will be another chance at rain or snow showers on Sunday, but they look like they will be light. Highs will be in the low to mid 40s in central and eastern KELOALND, and the low 50s in Rapid City.
It looks like weather will continue to be unsettled into early next week, with another wintry mix on Monday into early on Tuesday. Highs will be in the 40s both days. We will feel a surge of warmer weather, in the upper 40s to low 50s on Wednesday as sunshine returns. Wednesday looks like the warmest day of the week, because temperatures will cool back to normal or a little below normal for the rest of the week.
Extended range forecast models keep temperatures want to bring us colder than normal weather for Easter Sunday, currently projecting highs in the 30s.
