A hot and humid Wednesday

Storms will be mostly isolated and bring limited precipitation amounts

The heat and humidity Minnesota has seen so much of June returns Wednesday and includes a chance for severe weather, but not much rain along with it.

Wednesday’s forecast

Winds out of the south became more prevalent across Minnesota overnight, and because of the warmer flow, temperatures are already noticeably higher Wednesday versus the past two mornings. Most of the state started the day in the 50s, with even a few 60s, and now temperatures will heat up fast. Highs will be in at least the 80s for most of the state with 90s south and west.

The southerly winds increase and turn gustier Wednesday, with wind gusts over 20 mph for much of the state by the afternoon. This pulls in not only the heat, but also more humidity.

This pattern change is ahead of a storm system that pushes isolated showers and storms into northern Minnesota by the evening, and south through the state overnight. Even ahead of that more organized area of showers and storms, there will be a few light showers in northern Minnesota during the day.

The storms also bring an isolated (marginal) severe weather risk to northern and central Minnesota Wednesday evening and overnight, with large hail and damaging winds as the primary threat. 

Unfortunately, rain is expected to be limited with this system, with most places seeing under a quarter-inch, and much of western Minnesota missing the precipitation altogether.

The severe risk shifts to southern Minnesota Thursday, and weekend temperatures are expected to be more seasonable.

That extended forecast will be updated around 9 a.m.
