Later this week into the weekend, a large and possibly deep trough could move over the upper Midwest and western Great Lakes. At first, the Northland will be on the warmer side, east of the trough, with some rain possible Friday and Friday night. By Saturday, much colder air is expected to move in as the trough shifts east. It’s uncertain how much moisture will linger in that cold air, but there’s at least some chance for snow in parts of the Northland from Saturday into early Sunday. Some recent computer model runs have hinted at a significant winter storm for the area, but the models have been inconsistent, so the likelihood of a major storm this weekend seems low.
Over the next few days, highs in the Northland will be in the 50s and 60s, with 70s possible by Thursday and maybe sticking around into Friday.
Temperatures will be much cooler, in the 30s and 40s, near Lake Superior over the next few days due to persistent easterly winds. Some fog is also likely at times along the lake this week.
…Severe Thunderstorms tonight…

This afternoon, storms in southern Minnesota and stretching into southwest and central Wisconsin have mainly brought large, damaging hail, with reports of stones measuring 2 to 3 inches across—ranging from the size of a hen’s egg to even bigger than a baseball.
