2-Inch Hail, 80 MPH Gusts Charge Off Rockies into SE Wyoming, Eastern Colorado — SevereWX

Storms Brewing Off the Rockies

Visible satellite imagery shows deepening cumulus and early thunderstorms firing from the Laramie Mountains across to the Sangre de Cristo Range, plus along a boundary in east-central Colorado toward northwest Kansas. Steep lapse rates, dewpoints in the 50s to low 60s, and intense daytime heating are fueling MLCAPE to 1500-2000 J/kg this afternoon.

SPC's Mesoscale Discussion 2139 flags an initial isolated severe threat, mainly large hail up to 2 inches from potential supercells supported by 30-35 kt deep-layer shear. Storms should gradually spill off the high terrain eastward.

By evening, model trends hint at clustering, ramping up damaging wind potential to 65-80 mph gusts. A watch looks possible around 9-10 PM CDT (21-22Z) covering southeast Wyoming, far southwest Nebraska Panhandle, and eastern Colorado.

Peak Threats

Uncertainty lingers on exact evolution in east-central CO, but the setup screams severe hail early, winds later. Tune into WFOs CYS, BOU, PUB, and GLD for updates.

Stay Prepared: Have helmets or thick hats ready for hail, secure outdoor items against gusts, and monitor radar apps. Know your safe spot indoors away from windows. Severe weather can shift fast—stay alert!
