The National Weather Force has placed large portions of Minnesota under a Tornado Watch, in effect until 12:00 a.m. on Sunday, July 27, 2025.
Areas Affected:
-
Northern Plains Sector
-
Minnesota Regions: Western, Central, Northeastern, and Eastern parts of the state
Issued: July 27, 2025, at 3:25 p.m. CDT
Forecast Overview:
An upper-level disturbance moving west to east across the region this evening is expected to trigger rapid and intense thunderstorm development. These storms are projected to quickly become severe.
Due to favorable atmospheric conditions—specifically unidirectional winds aloft and strong low-level shear—there is a high potential for discrete supercells to form. The combination of surface instability and wind dynamics significantly raises the likelihood of tornado formation, including the possibility of strong and potentially long-track tornadoes.

According to National Weather Force’s advanced tornado risk modeling, storms developing under these conditions could spawn tornadoes reaching EF3 intensity or higher.
What This Means:
A Tornado Watch signals that conditions are favorable for tornado formation. National Weather Force classifies these into two levels: a standard Tornado Watch and an Enhanced Tornado Watch, the latter indicating a higher risk of widespread and intense tornado activity. Additional severe weather threats—such as large hail, damaging wind gusts, and flash flooding—are also likely across the affected areas.
Residents in the impacted zones are urged to remain weather-aware throughout the evening and overnight hours. Have a safety plan ready and stay tuned to trusted sources for updates and potential warnings.
