...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS PARTS OF THE
DESERT SOUTHWEST...THE SOUTHERN GREAT PLAINS...AND THE MID-SOUTH...

...SUMMARY...
Isolated severe thunderstorms are possible across a portion of the
Desert Southwest, the southern Great Plains, and the Mid-Mississippi
and Lower Ohio River Valleys, mainly during the late afternoon and
early evening.

...Interior Southern CA to northwest AZ...
A rich moisture plume emanating from the Gulf of CA exists across
southeast CA and southwest AZ where surface dew points are co*monly
in the low 70s. The northern extent of this moisture plume will be
the focus for isolated late afternoon thunderstorm development from
northwest AZ into interior southern CA, with more suppressed
development eastward along the Mogollon Rim. While the stronger
mid-level easterlies should be confined closer to the international
border, adequate flow will foster convection spreading west off
higher terrain. Within a deeply mixed thermodynamic profile, strong
to isolated severe downbursts are possible.

...Northern/west-central OK to far southern KS...
Strengthening low-level convergence in the early evening along a
southward-sagging cold front from southeast KS to northern OK may be
adequate for isolated high-based thunderstorms. A well-mixed
thermodynamic environment to its south and 15-20 kt mid-level
northerlies might be sufficient for a short-duration period of
isolated severe wind gusts until convection weakens after dusk. 

...Mid-MS/Lower OH River Valleys...
A minor mid-level low over southeast MO should minimally drift east
through the period. Persistent, slow-moving convection near its core
should diminish for a time this morning before redeveloping towards
peak heating this afternoon. Rich boundary-layer moisture will
co*pensate for the weak mid-level lapse rate environment to support
moderate buoyancy. A confined corridor of slightly enhanced
mid-level southwesterlies ahead of the disturbance might support a
few weakly organized updrafts within slow-moving clusters. Locally
damaging winds from strong gusts and perhaps small hail should be
the main threats.
