...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Scattered thunderstorms are possible across much of the Southwest,
mainly from late in the day into the overnight. Isolated
thunderstorms are also possible from the Texas Coast across the
Southeast States. Severe thunderstorm potential appears low.

...South TX/TX Coast across the Southeast and Mid-Atlantic...
Recent surface analysis places a low just off the northern
Mid-Atlantic coast. A cold front extends west-southwestward from
this low across central VA and middle TN to another low just east of
MEM. A cold front extends southwestward from this secondary low
across northern MS, central LA, and the TX Coastal Plain. This cold
front is forecast to push eastward/southeastward throughout the day,
and isolated thunderstorms are anticipated within this broad warm
sector that stretches from the TX coast through much of the
Southeast and Mid-Atlantic. Poor lapse rates and corresponding
limited buoyancy should keep updrafts weak and transient throughout
much of this region, limiting the severe potential. The only
exception is across south TX, where considerable low-level moisture
(i.e. dewpoints in the 70s) is in place, resulting in greater
buoyancy this afternoon. Even so, this region will be displaced well
south and west of the stronger mid-level flow, with weak shear
likely limiting updraft organization and persistence and tempering
the overall severe potential.

...Southwest...
Recent satellite imagery shows a well-defined upper low just off the
northern Baja California coast this morning. This low is forecast to
progress gradually eastward today, with strong mid-level flow
spreading from the base of this low eastward/northeastward across
the Southwest. Isolated to scattered thunderstorms are anticipated
ahead of this upper low, spreading from AZ this afternoon and
evening into NM overnight. In general, limited buoyancy should keep
overall thunderstorm strength low, despite strengthen deep-layer
vertical shear. The only exception is across southeast AZ, where
very strong vertical shear could overlap modest buoyancy for a few
hours this evening. Meridional orientation to the shear will favor
line segments and storm interactions, which should limit updraft
organization and the overall severe potential. That being said, a
few stronger storms with small, sub-severe hail and gusty winds are
possible. The overall severe potential is currently forecast to
remain too isolated to include any 5% probabilities.

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Scattered thunderstorms are possible across much of the Southwest,
mainly from late in the day into the overnight. Limited activity may
occur over North Carolina and southern Virginia. Severe thunderstorm
potential appears low.

...TX to SE States...
A zonal flow pattern is present today over the eastern half of the
CONUS, with a surface cold front moving across the TN Valley into
the Carolinas.  A few thunderstorms will be possible along/ahead of
the front from east TX into much of the southeast states today and
tonight, but the risk of severe activity is low.

...Southwest States...
A compact upper low will track eastward across Baja California this
afternoon, with an associated mid-level cold pocket affecting
northwest Mexico and the Four-Corners states.  Model guidance agrees
that scattered thunderstorms will affect these areas by late
afternoon and through the evening.  A few of the HREF members
indicate some risk of strong storms with small hail and gusty winds
over southeast AZ.  However, forecast soundings do not appear
sufficient to warrant severe probabilities at time.
