Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0147 PM CST Sat Dec 07 2024

Valid 072000Z - 081200Z

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

....SUMMARY...
Severe thunderstorms are not expected through tonight.

....20z Update...
No changes. Weak mid-level warm advection will continue to support
isolated thunderstorms through this afternoon across parts of
central and eastern TX. Recent Hi-res guidance also suggests storms
will gradually decrease in coverage with lightning becoming more
sporadic through tonight.

Isolated thunderstorms are possible over parts of the Pacific
Northwest with weak buoyancy and steepening mid-level lapse rates
ahead of the advancing Pacific Trough. Severe storms are not
expected, see the prior discussion.

..PREV DISCUSSION... /ISSUED 1029 AM CST Sat Dec 07 2024/

....TX...
Broad southwest flow aloft will maintain mid-level warm/moist
advection and persistent showers and isolated thunderstorms through
the forecast period.  It appears the highest probability of
lightning will be this afternoon, with decreasing coverage after
dark.  No severe storms are expected.

....Northwest WA...
A few thunderstorms are possible this evening and tonight over
northwest WA as a progressive upper trough and associated cold
pocket aloft moves into the area.
