September weather can be all over the map. And Minnesota's Monday weather map shows a chance of flooding in the northwest, while central and southern counties swelter.
A heat advisory issued by the National Weather Service covers 32 counties, where the heat index could reach triple digits during a one-day blast of warmth.
Meanwhile to the northwest, a slow-moving storm front means early-morning rains could sit over the Red River Valley well into the day. The Weather Service has issued a flood watch from Wadena north and west into North Dakota. More than two inches of rain could fall on the valley.
KARE-11 reported Sunday that some parched central Minnesota counties had received an inch or more of needed rain. As for the heat wave, it'll be short-lived. The forecast shows Twin Cities highs may not reach 70 by Friday.
