After a day of scattered severe storms yesterday, more scattered storms are back in the forecast. We have a number possible trigger points for scattered t-storms today. There is a left-over boundary around I-29 and the Sioux Falls area, a warm front in northeast SD, and another area closer to the main upper-level energy in southcentral SD. Be aware of scattered storm chances this afternoon, with large hail possible in the strongest storms. Highs will range from the upper 50s in the far northwest to mid 80s in NW IA.
Areas of rain, some of it heavy, will be likely in KELOLAND tonight. The best chances of locally heavy downpours will track from northern Nebraska into southeast SD, SW MN, and NW IA. The rain chances will gradually end from northwest to southeast late tonight into the first half of Saturday. The air behind this system will be very cool, with highs in the upper 50s in Rapid City tomorrow and 60s likely East River.
The next chance of organized rain will move across KELOLAND Sunday afternoon into the evening. Highs will be warming behind this system Monday and Tuesday, and we are expecting 70s in most areas by the middle of next week.
Showers and t-storms will also be possible again by Wednesday and Thursday as the active weather pattern continues.
