Areas affected...The Permian Basin and Trans-Pecos
Concerning...Tornado Watch 354...
Valid 302338Z - 310115Z
The severe weather threat for Tornado Watch 354 continues.
SUMMARY...A tornado, very large hail, and severe damaging wind
threat continues across the tornado watch.
DISCUSSION...Two confirmed tornadoes were recently reported very
close to MAF and briefly Denver City, in addition to very large
hail. The supercell near MAF continues to interact with the same
outflow boundary, and remains in a favorable environment for
additional tornadogensis cycles. The KMAF VAD indicated 0-1 km SRH
around 250-350 m2/s2 when the tornado occurred, and recent
mesoanalysis suggests a broad area within southeasterly surface flow
just behind the modified outflow boundary of 150-200 m2/s2 0-1 km
SRH. In addition, steep mid-level lapse rates are contributing large
CAPE within the hail growth zone as depicted in local RAP soundings.
Increasing low-level shear and moisture advection will continue
through the evening hours as a LLJ slowly intensifies. A discrete
storm mode is expected to continue (deep layer effective shear 55-60
kt normal to forcing) before mergers occur late this evening.
