Supercells Charge Along ND-MN Boundary with Baseball Hail, EF2 Twisters — SevereWX

Storms are firing up along a key outflow boundary stretching from northern North Dakota into northwest Minnesota, and the SPC's latest Mesoscale Discussion signals a 60% chance of a watch soon.

A mid-level jet streak is diving in with 45-50 knot winds aloft, bringing ascent that will erode any remaining cap on rich surface moisture. Temps in the mid-80s and dewpoints in the 70s are fueling strong instability, setting the stage for surface-based supercells through late afternoon and evening.

All severe hazards are in play: very large hail (most probable 2-3.5 inches) thanks to steep lapse rates and strong upper-level support; damaging winds to 70 mph; and tornadoes peaking at 85-110 mph (EF2 strength), especially near the boundary in northeast ND and northern MN where dewpoints hit the 70s F.

This setup echoes recent Plains patterns but zeroes in on the Dakotas-Minnesota border—scattered but potent storms could pack a punch.

Stay prepared: Monitor radar closely, secure outdoor items, and know your safe spot if storms approach. Check local NWS updates for watches.
