Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1120 PM CST Mon Jan 12 2026
Valid 131200Z - 141200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected on Tuesday.
...Synopsis...
Dry and stable conditions will persist across most of the CONUS
today. However, some modest moisture return is forecast across far
southern FL as a lobe of low surface pressure extends southward
along the Atlantic Seaboard. Generally warm temperatures through the
midlevels will limit instability and result in poor lapse rates.
Nevertheless, increasing moisture and modest forcing along a
developing sea breeze during the afternoon/evening could support a
couple of lightning flashes near the immediate coast or just
offshore the southeast FL Peninsula and portions of the Keys. Severe
storms are not expected.
