Mesoscale Discussion 0976

Areas affected...Portions of the Trans Pecos

Concerning...Severe potential...Watch unlikely=20

Valid 112137Z - 112300Z

Probability of Watch Issuance...20 percent

SUMMARY...Large to very large hail and severe wind gusts possible
through the evening across the Trans Pecos.

DISCUSSION...A cluster of updrafts have developed south of Fort
Stockton along a sharp dryline. Updrafts have yet to consolidate,
but are expected to eventually consolidate and organize into a
strong supercell given a downstream environment of 2500+ J/kg MLCAPE
and 40-50 knots of effective shear. This will support robust
updrafts capable of some very large (2+") hail. Long/straight
hodographs could favor some splitting supercells, especially early
in the life cycle. Most guidance suggests storm coverage should
remain isolated in this region. However, current radar/satellite
trends suggest storm coverage may be higher than initially thought.
At this time, the expectation for an isolated severe threat
precludes the need for a watch, but if more scattered storm
development appears imminent, a watch may need to be considered.
