Kansas Convergence Line Fires Up Supercells for 2.5-Inch Hail, 80 MPH Winds — SevereWX

A potent setup is brewing across west-central and north-central Kansas this evening, where a line of low-level convergence tied to a 1007 mb surface low in the western Oklahoma Panhandle is poised to spark supercell thunderstorms.

Surface dewpoints in the mid-60s to mid-70s F are fueling extreme instability, with RAP model estimates showing MLCAPE surging to 3000-4500 J/kg. A mid-level shortwave trough and vorticity maximum are ejecting eastward across the central High Plains, providing the lift for storm initiation along and near this instability axis.

Dodge City radar profiles reveal 0-6 km shear around 40 knots, including directional shear in the 1-4 km layer—ideal for supercell structures. These storms will likely produce isolated large hail (1.50-2.50 inches) and severe wind gusts (65-80 mph), with potential for intense short-line segments to add to the wind threat.

SPC's Mesoscale Discussion 1480 flags a 60% chance of a watch issuance within the next couple hours. Storms should develop soon after 7 PM CDT and persist into the late evening.

Stay prepared: Monitor radar updates, secure outdoor items, and have a severe weather plan ready. Know your safe room and heed local warnings as this threat unfolds.
