Areas affected...The High Plains of Colorado and the Nebraska
Panhandle
Concerning...Severe Thunderstorm Watch 350...
Valid 292255Z - 300100Z
The severe weather threat for Severe Thunderstorm Watch 350
continues.
SUMMARY...Scattered strong to severe thunderstorms will continue to
pose a threat of severe damaging wind gusts, marginally severe hail,
and possibly a land spout or two.
DISCUSSION...A few clusters of robust updrafts continue to slowly
progress eastward off the higher terrain of the NE Panhandle and
eastern CO plains. These thunderstorms developed within a lee
surface trough/dryline, within an environment characterized by very
steep mid and low-level lapse rates, relatively weak deep layer
shear, and enhanced surface vorticity. The latter, and localized
pockets of enhanced stretching, will continue to support non-zero
probabilities for landspouts. In addition, as the evening
progresses, continued cell mergers combined with inverted V
soundings/large downdraft CAPE could promote severe wind gusts via
wet downbursts. Before then, isolated hail stones up to 1-1.75" in
diameter will remain possible.
