We have a very active forecast today in KELOLAND as showers and thunderstorms will be likely in many areas. Heavy rain has fallen in western SD with widespread 2+” in the central and southern Black Hills. A flood watch is still in effect for far western KELOLAND.
Severe weather is possible this afternoon in parts of eastern KELOLAND. The highest chance of storms will be along a Mobridge-Huron-Mitchell-Yankton line. Strong winds are possible with a chance of an isolated tornado. Highs should reach into the lower to middle 70s in these areas.
Thunderstorms should exit most of KELOLAND this evening. Temperatures will fall into the lower to middle 50s. A mild day is forecast tomorrow with a lingering 20-30% chance of showers in the afternoon.
Slightly cooler weather is forecast on Thursday, but a stronger push of colder winds should arrive later in the day into Friday. In fact, NW winds on Friday could gust over 40mph with steady or falling temperatures during the day. Scattered frost is also possible Saturday morning.
Temperatures should rebound early next week, but there remains some uncertainty on just how warm. We have a lot of building cold just to our north that will bear watching early next week.
