...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected on Monday.
...Synopsis...
An amplified upper pattern, characterized by upper ridging over the
western CONUS and upper troughing across the central and eastern
CONUS, is forecast to be in place early Monday. This overall pattern
is expected to progress eastward throughout the day, with the upper
trough deepening as it moves toward the Eastern Seaboard and the
upper ridge dampening as it moves into the Plains.
At the surface, a cold front will likely stretch from eastern NY
southwestward through the Mid-Atlantic and off the central Gulf
Coast early Monday morning. Stable conditions will persist in the
wake of this front across much of the central and eastern CONUS. The
only exception is across southern FL, where a few afternoon
thunderstorms are possible ahead of the front. Stable conditions are
also expected west of the Rockies.
