Morning fog gives way to excessive heat

Widespread areas of fog Thursday morning will be replaced with sunshine and hot weather.  Humidity also remains high, prompting a heat advisory for the Twin Cities metro area.

Thursday’s forecast

Because of the very high humidity combined with light winds, fog developed across much of Minnesota overnight. It will lift quickly as temperatures rise Thursday morning, but as of 7 a.m. there are still a few reduced visibilities, especially in portions of the Arrowhead and central Minnesota. 

The state is starting Thursday in the 60s, with a couple 50s in northern Minnesota and a few 70s south. High temperatures will be right around 90 for most of the state, but high humidity will make it feel warmer, especially in southern Minnesota. Here is what temperatures are expected to feel like Thursday afternoon with the heat index factored in: 

Because of heat index values expected to be 95 degrees or higher, the Twin Cities area is under a heat advisory from 1 p.m. to 8 p.m. 

Skies Wednesday stay mostly sunny, and winds remain fairly light.

Heat continues through next week. That extended forecast will be updated around 9:30 a.m.
