KEY MESSAGES

- The probability for widespread hazardous weather is low through Saturday.

UPDATE

Issued at 614 PM CDT Fri Jun 19 2026

The overall severe weather threat has ended across the region as instability continues to wane and widespread subsidence starts to take hold. This will give way to lingering showers through the evening with the occasional lightning threat.

..Isolated severe storms this afternoon

Shallow but stout shortwave trough and attendant surface trough/cold front is traversing the region allowing showers and storms this afternoon. While dew points only into the 50s and temperatures remaining relatively cool into the 60s and low 70s, there is unseasonably cold air aloft contributing to sufficient instability to feed thunderstorms. Increasing wind speed with height will also help organize convection. This keeps main hazard of hail to size of quarters as the main threat. Couldn't rule out gusty winds to 60 mph either. This potential exists mainly in west-central MN through 6 PM, but also into southern Red River Valley.

Additionally, there is enough spin in the atmosphere (especially along wind shift lines supplying ambient vertical vorticity for updrafts to latch on to and tighten) to keep potential for brief weak tornadoes to develop, particularly toward central MN before 5 PM.

AVIATION /06Z TAFS THROUGH 06Z SUNDAY/

Issued at 1108 PM CDT Fri Jun 19 2026

Very limited aviation impacts are expected for the TAF period. Winds will remain light through tomorrow. While primarily from the northwest through tomorrow, given the light winds there is the potential for variable directions. Regardless, speeds will begin to diminish even more through tomorrow afternoon as a surface high approaches. VFR conditions will prevail. Skies should remain mostly clear, although some afternoon cumulus may develop. If this does occur, cloud decks should remain above 5000 feet. This activity would diminish in the evening timeframe.
