....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe storms are unlikely Wednesday.

....New England...
An upper low centered over the Great Lakes, with accompanying
cyclonic flow aloft, will remain the primary synoptic feature across
the eastern half of the CONUS Wednesday. Strong ascent and cool
mid-level temperatures east of a bent-back cold front over New
England will support scattered low-topped thunderstorms Wednesday
afternoon. The strongest of these storms are expected to remain
offshore, though some may approach coastal New England and Down East
ME midday. While isolated gusty winds are possible given strong
mid-level flow, severe storms appear unlikely with very limited
buoyancy and poor low-level lapse rates further inland.

....Southwest...
Other scattered thunderstorms will be possible within a plume of
mid-level moisture ahead of the western trough moving onshore over
CA and into the Southwest late Wednesday into early Thursday. Ascent
will overspread the modestly moist air mass from eastern CA and
southern NV into parts of the Four Corners. With only weak buoyancy
likely to develop ahead of the upper trough, organized severe storms
appear unlikely, though a stray strong gust is possible.

...Elsewhere...
Subsidence in the wake of the Northeast US system will strengthen
surface high pressure behind a cold front moving southeastward
across the US. Dry and stable conditions are expected within the
post-frontal air mass across the central US, with little threat for
thunderstorms. The exception being across far south FL, where
isolated storms are possible Wednesday afternoon along the coasts.
