KEY MESSAGES

- Sunday morning, a line of thunderstorms will move west to east across Minnesota. The line of storms may produce large hail and strong to severe winds as it progresses east. - Long duration period of heat and humidity begins Sunday, persisting through the week. The Extreme Heat Watch has been upgraded to Extreme Heat Warning for Monday. Heat impacts to be felt all week with little overnight relief and therefore a building heat stress.

- Chances for thunderstorms through next week. Storms will be capable of severe weather & torrential rain, if they are able to form.

REMAINDER OF THE WORK WEEK

The hot and humid conditions will continue through the work week with daily high temps around 90 degrees. What makes this long duration period of heat so impactful, is the lack of recovery in overnight temperatures. Overnight temperatures through the week will be in the upper 60s and low 70s across the area. This will further build the heat stress that could potentially last into the holiday weekend.

The threat for daily afternoon and evening showers and thunderstorms will continue through the week. Anywhere convection occurs, it will be rather robust with the continued hot and humid conditions in place. However, given that each day will likely feature some sort of capping, confidence is low with regard to timing and location. Continued monitoring our web page and social medias for updated information in the week to come.

AVIATION /12Z TAFS THROUGH 18Z MONDAY/

Issued at 702 AM CDT Sun Jun 28 2026

Main concern is a decaying line thunderstorms this morning, and potential for gusty east winds to persist for a few hours after the storms exit.

After the winds end, expect VFR conditions with southeast winds to continue this afternoon and evening. Could have some MVFR clouds at times as well.

KMSP...Showers and thunderstorms will move in this morning. The winds with these storms are not very strong, only around 20 kts. Once the storms move through, easterly winds could increase and last for a few hours. This is already ongoing across western Minnesota, and we anticiapte this to shift to KMSP later this morning, so did add a tempo for gusty winds.

/OUTLOOK FOR KMSP/ MON...VFR. Chc PM TSRA. Wind S 15-20G30 kts. TUE...VFR. Wind SW 10-15G25 kts. WED...VFR. Chc TSRA. Wind S 5-10 kts.
