Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0640 PM CST Tue Nov 28 2023
Valid 290100Z - 291200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
The risk of thunderstorms appears negligible across much of the U.S.
Some lightning was noted earlier today with convection beneath the
cold core of a weakening mid-level low, which is now a couple
hundred miles west-southwest of the northern California coast. The
remnant mid-level circulation may shift into coastal areas near
Eureka by late tonight, but the associated weakening, occluded
surface low and front are forecast to remain offshore of the
California coast. Stronger mid-level forcing for ascent and
cooling, within the exit region of a digging jet streak (to the west
of the mid-level trough axis), may approach coastal areas south of
San Francisco Bay overnight, possibly supporting a developing band
of frontal convection with some lightning.
