Areas affected...southeastern New Mexico and adjacent portions of
the Texas South Plains area

Concerning...Severe potential...Watch unlikely 

Valid 050526Z - 050730Z

Probability of Watch Issuance...20 percent

SUMMARY...Storms moving southward along the eastern New Mexico/Texas
border will continue to pose a risk for locally strong/damaging
winds for at least the next hour or two.  A WW is not anticipated at
this time, due to small spatial extent of this risk.

DISCUSSION...Latest radar loop shows a well-defined,
west-to-east-oriented band of storms moving southward across eastern
New Mexico and adjacent portions of Texas, with 80 kt inbound
velocity indicated by radar -- indicative of a well-organized band. 
With a 20 to 25 kt southeasterly low-level jet feeding this
convection, per recent WSR-88D VWP data, expect this southward
propagation to continue.

While a leading band of convection ahead of this main/stronger band
has led to some airmass stabilization (reducing temperatures into
the mid 70s and dewpoints to near 60), low-level theta-e advection
ongoing in conjunction with the low-level jet may continue to
sustain this rather well-organized band of storms for at least
another couple of hours.  During this time, strong/damaging winds
will be possible locally.  However, given small spatial extent of
this risk, and questions as to duration, preclude immediate
consideration for ww issuance.  If storms persist for another hour
or two, and it appears they may encroach on the more moist/unstable
airmass over the southeastern New Mexico vicinity, the need for a
new WW may be reconsidered.
