0622 PM CDT Sun Jul 01 2018
Areas affected...Portions of West/North Texas and far Southeast New
Mexico
Concerning...Severe potential...Watch unlikely
Valid 012322Z - 020115Z
Probability of Watch Issuance...5 percent
SUMMARY...Storms are forming near a surface front as convective
temperatures are being reached. Damaging winds are possible.
DISCUSSION...Storms continue to develop near a surface front and
along outflow boundaries across portions of West/North Texas as
areas reach their convective temperatures. There are very weak
flow/shear and higher heights/temperatures aloft along the western
extent of the Bermuda High. A well-mixed boundary layer, steep
low-level lapse rates (9+ C/km), high LCLs (~3 km AGL), and DCAPE of
1000-1500 J/kg per RAP soundings/mesoanalysis indicate the potential
for downbursts and strong wind gusts with hail also possible. Most
updrafts will struggle to sustain themselves and organize given the
weak shear/buoyancy (effective bulk shear < 20 knots; MLCAPE of
400-800 J/kg) and dry-air at low and mid-levels. Convection should
diminish after sunset, and the severe risk should remain isolated
with a watch issuance unnecessary.
