Expect above-normal temperatures through the weekend with 60s and 70s for afternoon highs. Isolated showers with minor disturbances move across Minnesota into Sunday.

Ian’s omega block keeping Minnesota warm

Ironically enough, Hurricane Ian, which has caused devastation in the southeast, is helping to keep Minnesota mild. Ian, combined with a Pacific northwest upper-level low is creating what we call an ‘“omega block” since it looks like the Greek letter, similar to a W.

The two, very slow-moving upper level lows are pools of cool, wet weather forcing warmer air upward in between. High temperatures will be back into the low to middle 70s across southern Minnesota Friday with 60s north.
