KEY MESSAGES
- High pressure and quiet weather remain in place through Thursday.
- 45-65% chances for precipitation return Friday. There is a 25-45 percent chance that eastern SD will receive at least a quarter of an inch of precipitation between 7 PM CDT Friday and 7 PM CDT Saturday. There is a marginal risk (1 out of 5) for severe thunderstorms on Friday.
UPDATE
Issued at 921 AM CDT Wed Aug 26 2026
Previous forecast remains on track, so no updates have been made this morning. High pressure continues to have influence over the region today, leading to dry conditions and mainly clear skies today (with the possible exception of some fair weather cumulus this afternoon). Winds out of the northwest will gust up to 20 to 25 miles per hour this afternoon, with the highest speeds coming over northeastern South Dakota and western Minnesota. Winds calm overnight, becoming light and variable, and can't quite rule out some pockets of fog developing early Thursday morning.
DISCUSSION
Issued at 111 AM CDT Wed Aug 26 2026
As of 1 AM CDT, temperatures across the region are in the upper 50s to low 60s with winds out of the west to northwest around 10 mph. High pressure and quiet weather remain in place today through Thursday.
Friday morning brings the return of storm chances with an incoming low pressure system. These storm chances are expected to last through the day and into early Saturday morning. MLCAPE Friday afternoon from the EC model is around 1500-2000 J/kg, falling to between 1200-1500 J/kg Friday evening. Lapse rates are around 7.5 C/km. SPC may put out an outlook for portions of the forecast area. Some 20-30% precipitation chances return Saturday evening. Limited precipitation chances exist through the rest of the weekend into the middle of next work week with increasing chances Tuesday. These storm chances are too far out to nail down severe potential.
Temperatures will hover right around to slightly above average through the 7-day forecast. Smoke is pretty limited for the next few days. Winds look to stay relatively light through the period.
