Areas affected...Parts of southwest Texas

Concerning...Severe potential...Severe Thunderstorm Watch likely=20

Valid 051756Z - 052000Z

Probability of Watch Issuance...95 percent

SUMMARY...The risk of supercells capable of producing large to giant
hail and locally severe gusts will increase through the afternoon. A
watch is likely for parts of the area within the hour.

DISCUSSION...Boundary-layer cumulus is deepening along the Davis
Mountains in the TX Trans-Pecos, with additional agitated cumulus
(albeit more shallow) evident into far southeast NM. Continued
diurnal heating amid deep/rich boundary-layer moisture (middle/upper
60s dewpoints) will yield strong surface-based instability. As
inhibition continues to erode, thunderstorms should develop over the
terrain features, before spreading eastward through the afternoon.
The strong buoyancy and a long/straight hodograph (characterized by
around 50 kt of effective shear) will favor discrete/splitting
supercells -- given weak large-ascent. Large to giant hail (3+
inches) will be the main concern with this activity, though severe
gusts and perhaps a tornado or two will also be possible. A watch
will likely be issued within the hour.
