...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast on Tuesday.

On Tuesday, a large upper trough will extend from the upper Great
Lakes into the Southwest, and will progress eastward into the
Northeast. Meanwhile, another backside speed max will dive southward
across the Rockies, while a ridge remains along the West Coast.

At the surface, substantial high pressure will be in place from the
Great Basin to the East Coast, with dry offshore winds along the
Gulf Coast. This high will shift east through the period, but
another centroid is forecast over the Intermountain West. 

There is a low chance of weak elevated instability developing into
Wed morning over southern FL, in association with the aforementioned
initial upper trough. While some thunderstorms may affect parts of
the Gulf of Mexico, poor lapse rates aloft will likely limit even
weak thunderstorm potential over land.
