Areas affected...NE Panhandle
Concerning...Severe Thunderstorm Watch 614...
Valid 232332Z - 240030Z
The severe weather threat for Severe Thunderstorm Watch 614
continues.
SUMMARY...The potential for severe gusts (60-70mph) is increasing as
storms grow upscale into a squall line near the WY/NE border and
move east into the NE Panhandle this evening.
DISCUSSION...Radar mosaic shows an intensifying band of storms over
far southeastern WY. RAP forecast soundings show 700-500mb lapse
rates approaching 9 degrees C/km atop a moisture-rich boundary layer
with low-middle 60s surface dewpoints in the NE Panhandle. Despite
the relatively weak flow in the troposphere, strong veering of the
wind profile is at least resulting in deep-layer shear supportive
for multicell organization in the form of a squall line. The
primary hazard will be severe gusts in the 60-70mph range.
