Mostly cloudy skies overnight. A light east to southeast breeze will help keep overnight lows in the 50s and lower 60s.

Clouds will stick around on Thursday, keeping temperatures a little cooler than normal. Highs will mainly be in the 70s, with a few spots reaching the low 80s. Winds will be light, but some gusts could reach 20 to 25 mph. Another weather system will bring more showers, mainly along and south of Interstate 90. Areas from Chamberlain and Beresford, South Dakota, to Storm Lake, Iowa, could pick up a quarter to a half inch of rain. Lighter amounts are expected farther north. A rumble of thunder is possible, but severe weather is not expected. Rain could continue into Thursday night before ending Friday morning.

Warmer weather returns Friday as sunshine increases. Highs will climb back into the upper 70s, 80s, and lower 90s. The warming trend continues through the weekend, with many places reaching the 90s and a few spots near 100 degrees. The hottest weather is expected along and west of Interstate 90. Humidity will also stay high, making it feel even hotter, so heat advisories may be needed if the forecast stays on track.

The heat begins to ease a little on Monday, with temperatures mostly in the 90s. Slightly cooler weather is expected by the middle of next week. There is a small chance for showers and storms to return at times, but confidence is low right now. Overall, the pattern looks hot and humid heading into next week.
