After a pleasant weather day yesterday, more 60 degree weather is in the forecast today. We’ve been tracking scattered rain during the early morning in northern KELOLAND with around .40” reported in Mobridge. Showers should exit the northeast with a pause in the rain much of the day expected. Highs will be around 65-70 in most areas, with lower 70s in south-central KELOLAND.
Scattered rain should redevelop this evening in the Black Hills region, with more isolated activity overnight east of Sioux Falls. The rain chances tomorrow will increase for Rapid City and Pierre, with scattered rain possible for Aberdeen. Sioux Falls only has a 20% chance of t-storms, but temperatures will be much warmer around 75. In fact, Sioux City could close to 90 tomorrow…something to watch for our NW IA viewers.
Any scattered storms that develop Wednesday afternoon or evening in the southeastern half of KELOLAND could be severe. The ingredients for the storms will be in place, but the trigger for the storms remains more uncertain. Stay tuned as we get more information on this scenario.
Rain chances will continue into Thursday as most areas of KELOLAND will be in the wrap-around moisture behind the low. Soaking rains are possible for much of western KELOLAND with 1-2” expected in Rapid City. Snow is even possible late Wednesday into Thursday for the Black Hills…something we’ll need to watch. Rainfall will be more scattered around Sioux Falls, while Pierre and Aberdeen will likely be somewhere in the middle with moderate amounts of .50” to 1” looking likely.
The extended forecast remains active with additional chances of scattered rain most days ahead. The timing will be biggest challenge, but temperatures will remain warm enough to include a few thunderstorms from time to time. This looks like a very typical early May forecast.
