KEY MESSAGES

- The probability for widespread hazardous weather is low through the weekend.

UPDATE

Issued at 615 AM CDT Sat Jun 20 2026

Clear skies prevail this morning across the region. Patchy ground fog is being observed near Langdon and occasionally near Fergus Falls. Overall, the forecast remains on track this morning, with temperatures in the upper 40s and calm winds.

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 /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 615 AM CDT Sat Jun 20 2026

VFR conditions prevail at all TAF sites through the period. There is a low chance for patchy ground fog near KDVL this morning; however, confidence is very low in coverage, thus will leave it out of the TAFs at this time. Overall, minimal impact potential through the period.
