Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0746 PM CDT Sun Sep 11 2022
Valid 120100Z - 121200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorm potential should remain low through tonight.
...01z Update...
Upper low is settling southeast into northern IL early this evening
as large-scale trough now extends across the MS Valley. Within the
base of this trough, a low-amplitude short-wave trough is beginning
to shift east across the central Gulf Coast. Seasonally high PW
values continue from the eastern Gulf Basin into the Middle Atlantic
where values are in excess of 2 inches, and profiles are moist and
adequately buoyant for a continued threat of at least isolated
convection tonight.
Farther west, with upper low off the northern Baja Peninsula, deep
southerly flow persists across northwestern Mexico into the lower CO
River Valley. This flow regime is maintaining an anomalously high
moisture plume into CA/southern NV where isolated lightning persists
with scattered convection over this region. Some thunder threat will
continue across much of the southwestern US tonight.
