Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0754 PM CDT Mon Mar 17 2025

Valid 180100Z - 181200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not forecast tonight.

....01z Update...

Upper trough is advancing inland along the Pacific Coast early this
evening. Isolated thunderstorms have developed beneath this trough
as cold mid-level temperatures have steepened lapse rates.  00z
sounding from OAK exhibited a few hundred J/kg SBCAPE, and this
seems to be representative across the interior valleys. Over the
next few hours nocturnal cooling should result in weaker updrafts
and less lightning. Overall trends should be down after 03z.
