Storm Center Update Tuesday PM - May 15

Overnight tonight will be a clear after these afternoon isolated thundershowers in central SD fade out with overnight lows in the low to mid-50s with a calm south wind.


Wednesday will be another sunny day in KELOLAND and it’s expected to be even warmer than today. Highs will be in the low 80s with a gentle south breeze. There is a slight chance of thunderstorms in western and central South Dakota Wednesday afternoon and evening; with a marginal risk some of those might become severe.


A broad area of low pressure will dominate the central US – including KELOLAND – on Thursday. That will bring widespread clouds, showers, and thunderstorms both Thursday and Friday. Afternoon temperatures will be in the 70s to mid -80s. At this time it appears we could see some two-day totals of an inch to two inches of rain. Southwest KELOLAND has a good shot at some of the forecasted thunderstorms to be strong to severe. 



The weekend looks like it will start cloudy and rainy and breezy on Saturday, with high temperatures dropping back below-normal to the low to mid-60s and Rapid City may not get out of the 50s on Saturday. There will be light to moderate amounts of rainfall in many areas on Saturday. On Sunday, there is a slight chance we could have some early morning showers, but skies should clear by Sunday afternoon. Highs will be only slightly cooler than normal, in the mid to upper 60s.

It looks like we will warm right back up on Monday, with sunny 70s. Next week looks like it will be warm all week right into the final weekend of May, with widespread 70s and a few 80s during that time period.
