...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are not expected on Monday.

... Synopsis ...

A midlevel trough will progress from the Northeast off the New
England coast on Monday, while the trailing cold front continues
southward into the Caribbean Sea. In the wake of this system, high
pressure and a relatively dry airmass will limit thunderstorm
potential across much of the CONUS.

... South Florida ...

North of the aforementioned front, diurnal heating of a moist
post-frontal airmass characterized by dewpoints in the mid-60s
should support isolated to widely scattered thunderstorms. Weak
buoyancy and a lack of significant large-scale ascent should
preclude any severe threat.

... Southwest into Texas ...

Farther west, a subtle, low-amplitude midlevel wave moving into
South Texas, combined with weak low-level warm advection and modest
moisture return will support a few rounds of isolated thunderstorms
across Southwest Texas into Central Texas. 

Additionally, isolated diurnal thunderstorms are possible across the
Southwest as midlevel moisture impinges on the region. This activity
is expected to remain focused over the higher terrain, and given the
weak instability and modest forcing, severe weather is not expected.
