Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1104 PM CST Fri Jan 19 2024

Valid 201200Z - 211200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the CONUS today.

...Western US...

Large-scale upper trough will shift inland across the western US
today as midlevel flow begins to increase at lower latitudes across
the eastern Pacific into northern Mexico. While southward-evolving
jet should result in weak buoyancy across portions of CA into the
Great Basin, any convection that develops in association with this
trough should remain too weak/shallow to warrant any meaningful risk
of lightning.
