Central High Plains Upslope Storms Prime for Large Hail, 70 MPH Winds — SevereWX

Scattered thunderstorms are firing up along the Colorado Front Range and Raton Mesa this afternoon, fueled by intense heating and upslope flow. Dewpoints near 60°F are boosting instability to 1500-2000 J/kg MLCAPE, while 25-35+ kt effective shear supports organized updrafts, including a couple of supercells.

Steep mid-level lapse rates over 7-7.5°C/km set the stage for large hail (most probable 1.00-1.75 inches), with damaging wind gusts to 55-70 mph also in play. Farther south into southeast Colorado and nearby areas, storms may evolve into outflow-driven clusters, ramping up the wind threat as shear eases to 20-25 kts.

SPC's Mesoscale Discussion 1998 flags a 60% chance of a Severe Thunderstorm Watch for parts of the central High Plains through 4:30 PM CDT. Lightning is already flashing in deeper updrafts.

Impacts: Golf ball-sized hail could dent vehicles and damage property; 70 mph gusts threaten power lines, trees, and outdoor items.

Keep an eye on radar for development near the Front Range and Raton Mesa. Have your severe weather plan ready—seek shelter indoors away from windows if storms approach. Monitor local NWS offices (BOU, PUB, AMA, GLD) and apps for updates.
