Issued at 117 AM CDT Mon Aug 24 2026 As of 1 AM CDT, storms are staying in western SD and out of our forecast area. Temperatures are in the 60s with winds out of the east to southeast at around 10 mph. A warm front followed by a cold front will move across the region throughout the day and into the evening hours. This warm front will help temperatures be a little warmer today with highs in the 80s to low 90s, warmest across central SD. The cold front will help pop off some thunderstorms this evening across central SD that will move southeast and across the area. There could be a second wave that moves down out of North Dakota closer to midnight Tuesday morning. There is a Slight risk (level 2 out of 5) for portions of south central SD and portions of northeastern SD and a Marginal risk (level 1 out of 5) for severe storms across the remainder of the forecast area. The main hazards for these storms will be golf ball size hail and 60-75 mph wind gusts. PWAT values are around 1.25" which is in the 97th NAEFS percentile so some brief heavy downpours are possible as well, although as a secondary threat. Overall chance of storms is 30-40% with the first round along the Missouri River and east to the James River. With the second round after midnight, chances across far northeastern SD increase to 40-60%. Our next widespread chance for storms will be Thursday evening into Friday as a low coming off the Rockies pushes out high pressure. Saturday and Sunday evenings could be stormy as well as we return to a more active pattern, but confidence on severe weather is low at this time. Temperatures after today return to right about normal, with a slight increase towards the end of the period. Winds Tuesday behind the cold front could gust up to 35 mph in northern SD. That cold front also looks to bring another round of elevated smoke to the area for Tuesday. There could be a band of higher concentrations over northeast SD, but little to no smoke is expected at the surface. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
