Clear to mostly clear skies are in the forecast to start the night but an incoming cold front will bring rain shower chances to the western half of KELOLAND mainly after Midnight. Eastern KELOLAND will continue to have clear to mostly clear skies until the front arrives tomorrow. Overnight temps will fall to the 40s.
Clouds will increase tomorrow as the front passes through the area and there is a decent chance we’ll see see showers and thundershowers swing through. Saturday’s high will top out in the upper 50s to mid-60s. Western SD will have strong winds, upwards of 20 to 40 mph.
Rain amounts will be heaviest in places where the thundershowers are found. These thundershowers may produce local amounts of .25-.75″. Winds will be gusty from the south ahead of the cold front.
Sunday (Mother’s Day) is still looking good, with mostly to partly 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 upper 60s to lower 70s East River, and mostly sunny skies and the mid 70s West River.
Tuesday will continue the warmer weather. 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 the potential for afternoon and evening thunderstorms due to the heating of the day and an approaching area of low pressure.
Sunshine returns on Wednesday with scattered rain Thursday and Friday. We’ll continue to see the warm highs in the 70s to near 80 through Friday.
