After the rains ended early this morning, skies have been partly to mostly cloudy. The central part of South Dakota has seen the most sunshine. The cloud cover has combined with a brisk northerly wind to keep temperatures below-normal, in the upper 40s to mid 50s.
There is a Frost Advisory in effect for Sioux Falls and SE KELOLAND tonight. Overnight we’ll have clear skies and light winds, a combination that will allow temperature to drop into the low to mid 30s.
Tomorrow we will see a return of abundant sunshine. Afternoon highs will be in the low to mid 60s, just a little cooler than normal for this time of year. Winds will be from the west, changing to the southwest. A few clouds will pass through the northern part of South Dakota.
We’ll see partly to mostly cloudy skies on Saturday, and there is a decent chance we’ll see some light showers, but they will be light and only amount to – perhaps – a few tenths of an inch. We’ll have a gentle westerly breeze, although Rapid City and western South Dakota will be windier.
Sunday (Mother’s Day) is still looking good, with mostly sunny skies. Highs will reach the lower 60s, still a few degrees below normal.
Strong warming will begin on Monday, with sunny skies and highs in the low 70s East River, and mostly sunny skies and the mid 70s West River.
Tuesday looks like the warmest day of next week. With partly cloudy skies we’ll see highs in the mid 70s. Pierre and the central South Dakota look to be even warmer, closer to 80s degrees. We will also be keeping an eye on Sioux Falls and SE South Dakota due to the potential for evening thunderstorms due to the heating of the day and an approaching area of low pressure.
We’ll keep rain showers in the forecast behind the front on Wednesday, as temperatures drop to the upper 60s East River and the low 70s West River. At this point we expect Thursday will be about the same temperature-wise, with sunny skies as an area of drier air moves in.
Extended range forecast guidance suggests we’ll remain near-normal, in the mid to upper 60s for the end of next week into the following weekend.
