Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0651 PM CST Mon Dec 23 2024
Valid 240100Z - 241200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast through tonight across the
contiguous United States.
...Discussion...
Little lightning activity is ongoing this evening across the CONUS,
with a few flashes noted just off the northern CA Coast earlier.
Weak levels of elevated instability ahead of the primary upper
trough may support sporadic flashes through tonight, mainly over
northern CA.
A greater chance of thunderstorms will occur over parts of OK and
northern TX, as low-level moisture spreads north beneath gradual
midlevel cooling overnight. The 00Z FWD sounding shows a deepening
moist boundary layer, though capped. This capping inversion will
cool/moisten with time, with a few hundred J/kg MUCAPE developing.
The strongest lift will be north of the surface warm front, from
central into eastern OK into western AR. Light showers were already
evident as of this writing along and north of I-40, and sporadic
lightning may occur after about 03Z.
