Showers in northwest Iowa and extreme southeast South Dakota will slowly wane as the afternoon goes on. Widespread showers and isolated thundershowers in western South Dakota will continue to move southeast through the evening. In general, the rain amounts will stay light with accumulation less than a tenth of an inch. The Hills of western South Dakota have a chance at a little more rain with any thundershowers that develop. A lot of the rain chances will run through this evening, then go away during the overnight. Lows will fall to the thirties and forties.
Friday will start with thick clouds in eastern and southeast KELOLAND. The clouds will leave by the afternoon to give way to mostly sunny skies. Temperatures will be near average with many locations in the sixties and low seventies.
Cold air will charge through KELOLAND Friday night into Saturday. The cold front will spark scattered light rain Friday night. Amounts will stay less than a tenth of an inch in many locations. Much of the rain will be done by Saturday morning, but breezy north winds will help push temperatures below average for the afternoon. The cold air will settle across KELOLAND on Saturday night with areas of frost possible Sunday morning. Eastern KELOLAND (along and east of the James River Valley) has the best chance for frost. After the cold start, skies will be sunny and temperatures will warm to near sixty in eastern KELOLAND to near seventy in the central and west.
Much warmer air will arrive early next week. Highs on Tuesday will be well into the eighties and low nineties.
