Supercells Fire Up Over NE Colorado into SE Wyoming with Large Hail Threat — SevereWX

Storms are bubbling up along convergence boundaries in the High Plains this afternoon, fueled by a jet streak over the central Rockies. The SPC's Mesoscale Discussion 1334 highlights a 80% chance of a watch as thunderstorms develop supercellular structure in portions of northeastern Colorado, southeastern Wyoming, and far western Nebraska.

Lengthened hodographs from enhanced flow should support a few supercells, primed for large hail thanks to straight hodographs and low freezing levels. Expect peak hail sizes of 1.50-2.50 inches, with severe gusts up to 55-70 mph possible as storms cluster amid a dry boundary layer.

Residual inhibition may slow initiation, but strong heating should erode it, allowing threats to materialize through late afternoon (valid until around 5 PM Moderate).

This setup echoes recent High Plains action but focuses on discrete development turning severe. Stay alert if you're in the area—monitor radar and local NWS updates.

Preparedness Tip: Have a severe weather plan ready. Identify your safe room, charge devices, and know how to receive warnings via NOAA radio, apps, or alerts. When thunder roars, go indoors.
