...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Wednesday.

...Synopsis...
A relatively dry and/or stable pattern will exist across most of the
CONUS today, with high pressure centered over the Great Basin and
lower MO/mid MS Valleys. Strong west to northwest flow aloft will
exist across the northern tier of states, around the southern
periphery of a large upper-level cyclone over central Canada.

The greatest chance for general thunderstorms will be relegated to
the FL Peninsula, where a stalled boundary will exist. Here, mid 70s
F dewpoints and daytime heating will yield around 2000 J/kg MLCAPE,
and midlevel lapse rates will be poor. Shear will be weak, but
outflow will likely be produced as storm coverage increases during
the afternoon over the interior.
