The severe weather threat for Severe Thunderstorm Watch 570

SUMMARY…Strong/locally severe thunderstorms continue across WW

DISCUSSION…Latest radar loop shows widespread thunderstorms —
including a few well-organized, rotating updrafts — occurring over
the central high Plains region. The storms are evolving near
multiple/complex boundary interactions across the area. With
low-level east-southeast flow advecting moist low-level air (60s
dewpoints) into the high Plains fueling the convection, expect
storms to continue for several hours.

A couple of brief tornadoes have been reported over the past couple
of hours, and large hail is also indicated with a couple of the most
intense updrafts. These risks — along with potential for locally
damaging wind gusts — are ongoing. With time, storms should grow
upscale, and spread eastward into/across southwestern Nebraska and
northwestern Kansas — where Tornado Watch 572 is currently in
