Large Hail Threat Builds in Central, Eastern Nebraska Overnight — SevereWX

Scattered thunderstorms are poised to fire across central and eastern Nebraska in the next few hours, carrying a serious risk of large hail.

A mid-level shortwave trough digging into the central Plains is lifting a plume of rich low-level moisture northward, fueling instability values of 3000-4000 J/kg. This setup, combined with 45-knot effective shear and steep mid-level lapse rates, favors elevated supercells despite a low-level cap.

The SPC highlights a primary threat of large hail, with 1.50-2.50 inch stones most probable. If one supercell dominates, hail exceeding 2 inches becomes likely, posing risks to vehicles, property, and anyone caught outside.

The discussion covers areas from near Lincoln northeastward through Omaha and into parts of southern South Dakota, valid through around 6 AM CDT. Watch issuance odds sit at 40%, so stay tuned to local NWS updates.

This early morning activity follows recent overnight storms in southern Nebraska, but focuses farther northeast with a similar hail emphasis.

Prepare now: Park cars in garages, secure outdoor items, and monitor radar closely if in the risk area. Have a severe weather plan ready for sudden intensification.
