Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0644 AM CST Mon Nov 11 2024

Valid 111300Z - 121200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms appear unlikely through tonight.

...Synopsis/Discussion...
In mid/upper levels, troughing will cross the Great Lakes and West
Coast regions this period, with a substantial synoptic-scale ridge
in between, across the Great Plains.  The western trough will cross
most of the Pacific Coast between 18-00Z today, then progress to
near a line from GEG-BOI-ELY-PHX to Hermosillo, MX.  In the lengthy
zone of strong large-scale ascent/cooling aloft that precedes the
trough, isolated thunderstorms already have been noted offshore, and
over the southwestern OR Coast.  This potential will spread inland
today until the trough moves past at least marginally favorable
low/middle-level moisture to support deep convection.

Elsewhere, thunder potential will be minimal, except for part of the
central Gulf Coast from near the mouth of the Mississippi River to
around PNS.  Isolated to widely scattered, episodic thunderstorms
will be possible near an inverted trough and convergence zone in low
levels, extending northeastward from the weakening, post-tropical
remains of Rafael.  Though most of the convection will remain over
the Gulf, isolated thunderstorms are possible in the outlook area.
