Wednesday: Much of the Northland could be facing a significant weather day. The first round of strong to severe thunderstorms is moving in from the west this morning. The strongest storms with potential for damaging winds and hail will extend near Grand Rapids to International Falls, then the morning storms should weaken moving east of there.
We will likely see scattered thunderstorms return in the afternoon and evening for the Arrowhead and into Northwest Wisconsin as a warm front approaches. The atmosphere is primed with moisture, so these storms will be capable of heavy rain and flash flooding. Large hail and damaging winds will also be possible, and even an isolated tornado can't be ruled out.
Wednesday night: Severe thunderstorms. Low 63. S wind 5-10 mph.
Thursday: Mostly cloudy with a chance for thunderstorms. High 83. Southwest wind 5-10 mph.
Friday: Mostly sunny. High 82.
