...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS NORTHERN
KANSAS AND SOUTHERN NEBRASKA...

...SUMMARY...
Severe thunderstorms capable of producing large hail,
severe/damaging winds (some 75+ mph), and a couple tornadoes remain
possible tonight, especially across southern Nebraska and northern
Kansas.

...01z Update - Central Plains/Missouri Valley...
Primary scenario this evening will be an upscale-growing/organizing
cluster of storms across northern Kansas and southern Nebraska. A
bit more spatial room has been given (southward adjusted) across
northern Kansas (mostly north of I-70) for what may still be a
post-01z increasing damaging wind potential, including
significant-caliber wind gusts across northern Kansas and far
southern Nebraska, aside from a lingering broad regional potential
for some large hail as well. Measured 85 mph gusts have recently
been reported near Colby, Kansas.
