We’re seeing an explosion of strong to severe thunderstorms late this afternoon across western, central and southern Minnesota as a potent low pressure system heads NE out of the Dakotas.

Forcing associated with the upper level trough and area of low pressure has spread far enough east into the warm, humid and unstable air to cause numerous strong to severe storms late this afternoon.

Expect showers and thunderstorms to move from southwest to northeast across northeast Minnesota and northwest Wisconsin through late this evening.
