High temperature forecast for Wednesday and Thursday, September 22-23, 2021

We’re looking at daytime highs in the mid 60s to around 70 in northeast Minnesota and northwest Wisconsin for Wednesday, and in the mid 60s to low 70s for Thursday, so not too bad at all for late September.

After a few weeks of a more active weather pattern in our area, the weather pattern will quite down significantly through this weekend, with our only chance for a few rain showers coming in the Friday-Saturday time frame due to a cold frontal passage and upper level low which digs SE toward the Great Lakes, but any rain we get should be on the light side and not widespread at all the way it looks now.
