Areas affected...Central Plains

Concerning...Severe Thunderstorm Watch 320...

Valid 010226Z - 010430Z

The severe weather threat for Severe Thunderstorm Watch 320
continues.

SUMMARY...Convection should increase across much of ww320 over the
next few hours. Severe threat continues.

DISCUSSION...Negative-tilt short-wave trough is ejecting northeast
at roughly 25kt. Leading edge of stronger forcing should overtake
the frontal zone in the next few hours and this will likely lead to
an increase in thunderstorms along/just behind the cold front as
700mb temperatures (capping) cool. Current thunderstorms northwest
of GRI are slowly intensifying, and severe hail is likely observed
in several updrafts. Overall convective trends should be up over the
next few hours.
