June 2021 Heat Wave
"It's not the heat, it's the longevity! A heat wave of historic duration and intensity for so early in the season has gotten summer 2021 off to a toasty start in Minnesota. Warm air arrived on Thursday June 3rd, with temperatures ratcheting up substantially Friday and Saturday. Intense heat remained in place over most of the state Sunday, and over the southern 2/3 to 3/4 of the state during the week. The heat originated from southerly flow that developed between an area of low pressure over the Rockies, and a large are of high pressure in the southeastern US. With neither weather system moving much, the southerly winds maintained a steady feed of hot, and eventually humid air into the region. Things got started on Thursday June 3rd, with temperatures rising well into the 80s across the state, with 90s in central, southern, and especially western Minnesota. Though this day produced the highest temperatures to date at many stations, it was a mere appetizer to the heat-feast that would follow."
Simulated Radar From 7AM Thursday to 7AM Friday
Here's the simulated radar from 7AM Thursday to 7AM Friday, which shows fairly quiet conditions on Thursday across much of the state with the exception of a few isolated PM storms. The best chance of storms arrives on Friday, especially late in the day when scattered storms develop late in the day from the Twin Cities north. Some of the storms could be a little bit on the more vigorous side with locally heavy rainfall.
