Early evening water-vapor imagery shows a potent large-scale trough
over the East. A strong belt of subtropical upper-level flow
extends from Mexico across the Gulf of Mexico and the FL Peninsula.
A cold front over the FL Peninsula will continue to move south this
evening into the overnight hours and reach the FL Straits late. A
couple of lingering thunderstorms this evening over the central and
southern portion of the FL Peninsula will continue to wane in
coverage and intensity. Farther west, a stationary mid to
upper-level low and steep lapse rates will promote isolated to
widely scattered showers and thunderstorms this evening, before
diminishing late tonight. Elsewhere, surface high pressure centered
over the south-central U.S. will lead to tranquil conditions.
