Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0635 PM CST Sun Jan 21 2024

Valid 220100Z - 221200Z

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

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

....01z Update...

Changes are not warranted to the 20z outlook.

Isolated thunderstorm threat continues tonight across portions of
TX, southeast AZ, and along the CA Coast. The greatest risk for
lightning is within a strong low-level warm advection regime over
the southern Plains, primarily along the I35 corridor in TX. LLJ
will increase across the southern Plains this evening, and
increasing PW values atop cool/stable boundary layer will aid
buoyancy for elevated convection across this region.

Steep lapse rates across southeast AZ may yet allow a few updrafts
to generate lightning across this region, but lightning has proven
very sparse with this activity.

Isolated flashes of lightning may also develop along the CA Coast
later tonight in response to a short-wave trough that will approach
this region after midnight.
