After last night’s thunderstorms and this morning’s fog both left, we’ve had a pleasant Monday. Broken cumulus clouds are spread across KELOLAND, and temperatures have been below normal, in the 70s, with a light northerly breeze. A few places west of the Missouri River have reached the low 80s. 

More active weather is expected in this area over the next 48 hours. Tonight eastern KELOLAND, including Sioux Falls, will see clouds increasing overnight. Our lows will be in the upper 50s to low 60s. At the same time, an area of low pressure will be parked over the southwest corner of South Dakota, and we could see some thunderstorms in western and central parts of the state. Some of those thunderstorms could even be on the strong side. 

Tomorrow we’ll see a low pressure system and the accompanying fronts slide through southern KELOLAND. High temperatures will remain a bit below normal, in the upper 70s to low 80s, with a SE breeze. Thunderstorms will become more numerous, especially during the evening hours. We expect storms to continue through the nighttime hours. 

Rains should come to an end Wednesday morning. Some places could get a real soaking, including Sioux Falls and SE KELOLAND. In fact, the Weather Prediction Center says much of KELOLAND has a marginal risk for heavy rain causing flash flooding. 



After the rains end, Wednesday afternoon will be cools with a northerly breeze, with highs only in the mid 70s East River, while it should recover to the low 80s West River.


Thursday should be mostly sunny behind the departing storm systems. We’ll warm up, into the low 80s East River and the mid 80s West River.

We’ll carry some widely scattered rain showers – or possibly a thundershower – on Friday, with highs remaining in the low to mid 80s.

The weekend is looking warmer and pleasant. Right now we’re going with temperatures near-normal for this part of August, in the low to mid 80s East River, while Rapid City and the west have a shot at 90. We’re going mostly sunny, with a lack of significant weather features except for the warm front that will cross the area.

After that, it looks like we’re going to see thunderstorms on Monday. That will be on the leading edge of what appears to be a significant period of above-normal temperatures that should carry through much of next week.
