SPC Flags Enhanced Severe Storm Risk for Kansas, Nebraska With 75 mph Winds on June 20
3 articles · Updated · The Watchers · Jun 19
Summary
Saturday’s outlook puts parts of Kansas and Nebraska under an Enhanced Risk, with large to very large hail, tornadoes and wind gusts above 75 mph possible from afternoon into evening.
A deepening lee cyclone over eastern Colorado, a front near southern Nebraska and a dryline into the southern Plains are expected to pull richer moisture north and sharply increase instability and wind shear.
Storms should first form by mid-afternoon from eastern Wyoming to the Nebraska Panhandle, then expand along eastern Colorado, western Kansas and central to southern Nebraska as supercells capable of very large hail.
By evening, those supercells may merge into one or more mesoscale convective systems tracking into central and eastern Kansas, shifting the main threat toward widespread damaging winds and embedded tornadoes.
