..no severe thunderstorm areas forecast...
a few thunderstorms may occur over the Florida vicinity Sunday.
A western-ridge/eastern-trough configuration will persist across the
U.S. Sunday, though some amplification of the overall flow field is
expected -- owing to a northeastern Pacific trough expected to begin
encroaching on the western noam coast during the period.
At the surface, a cold front is forecast to move quickly offshore
into the western Atlantic, while sagging slowly southward across
Florida through the period. In the wake of the front, cold high
pressure and a Continental polar airmass will continue to spread
across much of the country.
As the cold front advances southward across Florida, showers and a
few embedded thunderstorms are expected. With weak instability
however, severe weather is not expected.
