Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0610 AM CST Tue Jan 04 2022
Valid 041300Z - 051200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible today across western
Washington.
...Synopsis...
Cold midlevel temperatures and associated steep low-midlevel lapse
rates will persist near the WA coast today, with an associated
threat for isolated lightning flashes mainly this morning into early
afternoon. Thereafter, warming profiles aloft with rising heights,
and resultant lowering of equilibrium levels, will reduce the
potential for convection deep enough to produce lightning.
Otherwise, a cold and/or dry continental air mass will preclude
thunderstorms across the majority of the CONUS. The only potential
exceptions will be across the FL Straits and just off the Carolinas,
but any deep convection/lightning flashes should remain sparse and
confined to offshore waters.
