North Dakota Storms Gear Up for Supercell Hail and Gust Assault Tonight — SevereWX

A deepening cumulus field near a subtle meso-low triple point in north-central North Dakota is priming the pump for storms this evening. SPC's Mesoscale Discussion 1635 highlights increasing odds of initiation around 7 PM CDT as heating erodes remaining convective inhibition, especially around Bottineau and McHenry Counties. A few storms could also pop farther south along a surface trough near Bismarck.

The environment screams supercell potential: MLCAPE up to 3500 J/kg meets 30-40 kt effective shear and veering winds. Initial storms may organize as right-moving supercells before evolving into a cold-pool-driven system, packing 1.00-1.75 inch hail and 55-70 mph gusts. Tornado risk stays low due to limited time over an existing outflow boundary.

Storm coverage is the wildcard—no big forcing for ascent means isolated development is most likely. But if multiple severe storms fire, expect a severe thunderstorm watch soon (40% probability).

Residents in north-central and northeast North Dakota should monitor radar closely this evening. Have a weather app handy and know your safe spot indoors.

Stay prepared: Review your severe weather plan, charge devices, and heed local warnings to stay safe tonight.
