Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0636 PM CST Sat Dec 14 2024
Valid 150100Z - 151200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected through tonight.
...Discussion...
Overall thunderstorm coverage will remain very isolated tonight.
Convection near the cold core of a shortwave trough over central MO
has nocturnally weakened. Still, scant elevated buoyancy might yield
sporadic flashes as the trough continues east towards southern IN,
and within the broad but modest low-level warm conveyor arcing back
into the Ark-La-Miss. Greater buoyancy will remain confined to east
TX but weak large-scale ascent suggests thunderstorm probabilities
will be low. Sporadic thunderstorms may linger longest across parts
of the Pacific Northwest coast. Here, steep mid-level lapse rates
around 8 C/km per 00Z UIL/SLE soundings will eventually weaken as
mid-level temperatures warm from south to north in the early
morning.
