North Dakota Triple Point Fuels Supercell Surge for Large Hail, Gusts — SevereWX

A subtle meso-low triple point is deepening the cumulus field across Bottineau and McHenry Counties in north-central North Dakota, setting the stage for storm initiation by 7 PM CDT.

SPC's Mesoscale Discussion 1635 highlights increasing odds for isolated severe storms, fueled by eroding convective inhibition, continued daytime heating, and low-level convergence. An extra storm or two could pop farther south near a surface trough below Bismarck.

The environment screams supercell potential: MLCAPE up to 3000-3500 J/kg pairs with 30-40 kt effective bulk shear and veering winds. Early storms may organize as right-moving supercells before transitioning to a cold-pool-driven system. Primary threats include 1.00-1.75 inch hail and 55-70 mph wind gusts. Limited residence time along an outflow boundary keeps tornado risk low.

Storm coverage remains the wildcard—no strong large-scale lift means isolated development is most likely. But if multiple severe storms materialize, a severe thunderstorm watch could drop.

Stay prepared: Review your severe weather safety plan, keep devices charged for alerts, and monitor radar via local NWS offices (FGF, BIS). Have helmets or padding ready for hail protection if outdoors.
