...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible today in parts of Florida
and in the Pacific Northwest. No severe threat is expected today or
tonight across the continental United States.
...DISCUSSION...
Several shortwave troughs will move across the continental United
States today. The first will move eastward into the western Great
Lakes. A second will move through the Gulf Coast region but will
become less defined with time. A third will move into the Pacific
Northwest. Ahead of this trough, strong large-scale ascent and
mid-level moisture may be sufficient for isolated thunderstorms. In
the southeastern U.S., a moist airmass will be located across the
central and southern Florida Peninsula. As destabilization occurs
today, isolated thunderstorm development may take place, mainly from
the east coast of Florida southward into the Florida Keys. Elsewhere
across the continental United States, thunderstorm development is
not expected today or tonight.
