KEY MESSAGES

- Showers will continue to diminish through the evening.

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 /00Z TAFS THROUGH 00Z SATURDAY/

Issued at 614 PM CDT Fri Jun 19 2026

Showers and thunderstorms will continue to diminish through the evening hours, giving way to VFR conditions through the end of the TAF period. Winds will remain northwesterly through at least early tomorrow afternoon, however given the relatively low magnitudes, variable directions due to terrain impacts may arise. Regardless, expect magnitudes to remain below 10 knots and generally a northwesterly direction. No other aviation impacts are expected.
