A steamy Monday, with a t-storm chance; heat advisory for the Twin Cities metro

It was a steamy Sunday across central and southern Minnesota and parts of western Wisconsin. Portions of central and northern Minnesota saw some strong to severe thunderstorms Sunday afternoon and Sunday evening, and a few strong thunderstorms clipped the northeast part of the Twin Cities metro area in the evening. Some spots in Minnesota also had heavy rainfall.

Thunderstorm winds caused large waves on Mille Lacs Lake for awhile on Sunday:

How hot was it?

The Sunday high temp at Minneapolis-St. Paul International Airport was 92 degrees. It was only our second day with a high of 90 or warmer at MSP airport this year.  By July 14 of 2018, we had tallied 13 days with highs of 90 or greater.  The Minnesota State Climatology Office states that we average 12.9 days per year with highs of 90 or warmer in the Twin Cities.  Our Twin Cities record was 44 days of 90 or warmer, in 1988.
