[html]MD 1983 CONCERNING SEVERE THUNDERSTORM WATCH 645... FOR WESTERN MONTANA
Mesoscale Discussion 1983
NWS Storm Prediction Center Norman OK
0604 PM CDT Fri Aug 23 2024
Areas affected...Western Montana
Concerning...Severe Thunderstorm Watch 645...
Valid 232304Z - 240100Z
The severe weather threat for Severe Thunderstorm Watch 645
continues.
SUMMARY...Severe wind gust potential continues with convection this
evening.
DISCUSSION...Satellite imagery depicts a well-defined short-wave
trough, extending from northeast OR-ID-extreme western WY, lifting
north across the northern Rockies. Large-scale height falls are
noted ahead of this feature as 500mb flow on the order of 50kt
translates across the Bitter Roots into western MT. An arcing
corridor of scattered robust convection has developed ahead of the
short wave, and while this activity is developing within a
weak-instability airmass, severe gusts have been co*mon. Over the
next few hours it appears the primary area of concern will extend
across northern portions of ww645 where instability has yet to be
overturned.
