Day 1 Convective Outlook

...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible across southeast Florida
today, but severe thunderstorms are not expected.
...Synopsis and Discussion...
Surface high pressure will remain dominant today across much of the
Plains into the MS/OH Valleys amid persistent upper troughing over
the central/eastern CONUS. As such, overall thunderstorm potential
should remain generally low, with perhaps a couple exceptions.
Isolated thunderstorms appear possible across parts of
coastal/southeast FL along/near a weak inverted surface trough amid
greater low-level moisture and modest buoyancy.
An upper low over the eastern Pacific should develop
south-southeastward through the period off the coast of southern
CA/northern Baja. Cool temperatures aloft may support weak MUCAPE
and very isolated lightning flashes with convection that should
remain mostly offshore this afternoon. Overall coverage of
thunderstorms appears less than 10% across coastal southern CA.

...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible across southeast Florida
today, but severe thunderstorms are not expected.
...SE FL...
A weak surface boundary lies just offshore along the southeast FL
coast. Scattered showers and a few thunderstorms will persist along
this boundary through early evening as an upper trough progresses
across the region. This threat should weaken after dark. No severe
storms are expected.
