Omaha Vicinity Supercells Load Up for Baseball Hail, 80 MPH Winds

The Storm Prediction Center has flagged a rapidly intensifying severe weather setup in portions of southeast Nebraska, southwest Iowa, and far northeast Kansas. Strong destabilization fueled by outflow from earlier storms is setting the stage for isolated supercells to fire up as early as 5-6 PM CDT (22-23Z).

An 18Z sounding from Omaha revealed nearly 4000 J/kg MUCAPE with steep lapse rates and favorable wind profiles for rotating storms. Midlevel cumulus is already congealing overhead, signaling weakening inhibition and imminent initiation. Once capping breaks, expect quick development of supercells capable of very large hail near 2.5 inches (baseball size) as the primary threat, alongside damaging gusts to 80 mph.

Evening upscale growth could amplify wind risks through storm clustering. SPC pegs watch issuance odds at 80% within the next 1-2 hours. Most probable peaks: hail 1.50-2.50 inches, winds 65-80 mph, tornado intensity up to 90 mph.

This MD (1471) underscores a high-confidence severe window late afternoon into evening. Track updates via SPC and local NWS offices (OAX, DMX, EAX).

Stay Prepared: Monitor radar closely, secure outdoor items, and have a severe weather plan ready—seek shelter if storms approach. #SevereWX #NebraskaSevere
