Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0632 PM CST Sun Dec 14 2025
Valid 150100Z - 151200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected tonight.
...01z Update...
Northwesterly flow is deepening across the southern FL Peninsula as
the primary synoptic front surges toward the FL Straits. Isolated
showers are lingering across this region, with even a few flashes of
lightning near West Palm Beach. However, this activity should
continue to wane then focus well offshore over the next few hours.
00z sounding from UIL is quite stable this evening with poor lapse
rates noted through 6km. Late tonight elevated buoyancy may increase
near the WA coast such that weak convection is able to develop ahead
of approaching short-wave trough. If lightning is noted with this
activity it will remain quite sparse.
