Valid 291200Z - 301200Z



...NO THUNDERSTORM AREAS FORECAST...



...SUMMARY...

Thunderstorms are unlikely Wednesday.



...Synopsis...

A deep upper low over the central US will continue to intensify

before merging with a broader trough over the eastern US Wednesday

and Wednesday night. A surface low over the Mid South will deepen

and move toward the Atlantic Coast as a strong cold front continues

to push offshore through the Gulf and Southeast. High pressure will

develop within the post-frontal air mass supporting widespread

offshore flow and drier conditions across much of the CONUS.



The only exception will be across far south FL and the immediate Mid

Atlantic coast where remaining southerly winds will support modest

surface moisture for part of the day. However, the relatively

shallow nature of the moisture and mid-level drying/subsidence

southeast of the jet max will overspread the area ahead of the

advancing front. This should limit thunderstorm potential before the

cold front scours the remaining moisture offshore. Thus,

thunderstorm chances currently appear to be below 10% over the

CONUS.
