...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms are possible across portions of the Florida
Peninsula and Keys. No severe storms are anticipated.

...Synopsis...
A pair of phased shortwave troughs will move east-southeastward
during the period with the northernmost shortwave moving across the
northern Plains and the southernmost shortwave moving across the
northern Great Basin and central Rockies. An associated cold front
will track quickly southeastward across the Plains and upper/middle
MS Valley. However, in spite of these features and their related
forcing for ascent, dry conditions will result in an environment
hostile to deep convection. Farther south, shortwave trough
currently moving through the base of the longwave trough covering
the eastern CONUS will continue eastward through the FL Peninsula
early in the period. A few isolated thunderstorms are possible
across the Peninsula through the early afternoon, primarily along
the west-central coast. Isolated thunderstorms will remain possible
across southern FL and the Keys during the afternoon and evening.
Limited instability will temper updraft strength, keeping the severe
threat very low.
