Day 1 Convective Outlook

0638 PM CST Wed Nov 26 2025
Valid 270100Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
The risk for thunderstorms appears negligible across much of the
nation tonight.
...01Z Update...
...Southern Florida/Keys...
Convection in a small cluster initially centered over interior
southern Florida, generally to the northwest of Greater Miami, has
undergone recent weakening. While occasional lightning persists in
stronger cores, guidance suggests that potential for this continuing
inland and near coastal areas will become increasingly negligible
through 02-03Z.
Otherwise, although more uncertain due to model spread, potential
for scattered convection capable of producing lightning might
increase late tonight near the lower Keys, if an increase in
large-scale ascent is able to overcome inhibition associated with
relatively warm layers aloft.
