Friday’s storm wave looks likely to from in central Minnesota and could impact the Twin Cities late Friday afternoon into the evening.

Here’s a breakdown of storm coverage and timing through Friday.

A cold front in the Red River Valley will cut into the warm unstable air mass. That will trigger a line of storms in northwest Minnesota this evening.

Forecast models agree on a band of strong to severe storms blowing up from the Red River Valley into northwest Minnesota this evening. The (severe) storm line will likely blow through the central Minnesota lakes tonight and may fade as it approaches the Twin Cities after midnight, likely toward 2 a.m.
