Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0120 PM CST Wed Jan 12 2022
Valid 122000Z - 131200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Scattered thunderstorms may develop near southeastern Florida
coastal areas, mainly after midnight EST.
...20Z Outlook Update...
Mid/upper-level trough amplification is underway near/east of the
Mississippi Valley into the Atlantic Seaboard. Within this regime,
one short wave trough is beginning to dig southeast of the Louisiana
Gulf coast, and forecast to gradually turn eastward through the base
of the larger-scale troughing, across the Florida Peninsula, toward
09-12Z. In advance of this feature, surface winds are forecast to
back from easterly to northerly across the Florida Peninsula, to the
northwest of a developing surface frontal wave. In response to
strengthening mid-level support and low-level convergence, models
generally indicate increasing lift after 06Z, focused near
southeastern coastal areas. Given the continuing presence of at
least weak conditional instability, scattered thunderstorm
development appears possible. Although this seems most probable
near/offshore of coastal areas, both Rapid Refresh and NAM forecast
soundings suggest that initiation over interior areas around the
Lake Okeechobee vicinity might not be entirely out of the question.

.PREV DISCUSSION... /ISSUED 1018 AM CST Wed Jan 12 2022/
Very similar to yesterday, showers and a few thunderstorms will be
possible this afternoon and tonight along the coast of southeast FL
and the Keys - mainly offshore. Weak shear will continue to
minimize the risk of severe storms.
Otherwise, dry and stable conditions will preclude thunderstorm
activity during this period.
