MD 2146 CONCERNING SEVERE THUNDERSTORM WATCH 622... FOR PORTIONS OF SOUTHERN COASTAL CALIFORNIA
Mesoscale Discussion 2146
NWS Storm Prediction Center Norman OK
0742 AM CDT Tue Oct 14 2025
Areas affected...portions of southern Coastal California
Concerning...Severe Thunderstorm Watch 622...
Valid 141242Z - 141415Z
The severe weather threat for Severe Thunderstorm Watch 622
continues.
SUMMARY...A damaging gust may occur this morning.
DISCUSSION...A pronounced mid-level trough and an associated 80+ kt
mid-level jet streak is currently overspreading the LA Basin, with
60 F surface dewpoints impinging on the shoreline. Intense dynamic
forcing currently supports a strong vertical wind field and
accompanying shear profile over southern CA, where a low-topped
confluence band is currently progressing. Some of the stronger
showers in the region have supported damaging gusts over the past
couple of hours, including a measured severe gust and wind damage
report in Ventura/Los Angeles counties. The current thinking is that
the potential for an additional damaging or perhaps severe gust will
remain in place through the morning hours as the low-topped
convective band continues to take advantage of scant buoyancy in the
region.
