Areas affected...Northwest TX

Concerning...Severe Thunderstorm Watch 282...

Valid 290230Z - 290330Z

The severe weather threat for Severe Thunderstorm Watch 282
continues.

SUMMARY...Severe threat is waning across the southern High Plains.

DISCUSSION...Dryline convection has struggled to move appreciably
east before weakening, this despite ample 850mb inflow and higher boundary-layer moisture immediately downstream. One lingering
robust updraft continues west of Munday, likely due to more
south-southwesterly flow where surface temperatures remain in the
90s. However, boundary-layer cooling should lead to weakening of
this storm over the next 1-2 hours and aside from locally gusty
winds overall severe threat should be waning.

Areas affected...Portions of central/southern Texas

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

Valid 081715Z - 081815Z

Probability of Watch Issuance...80 percent

SUMMARY...The threat for large hail and damaging winds will increase
through the afternoon across portions of central Texas and spread
southeastward toward the coast by evening. A severe thunderstorm
watch is likely.

DISCUSSION...Surface-based convection is beginning to develop ahead
of a remnant MCV left behind from yesterday's convection. With
clear skies downstream and dewpoints in the upper 60s/low 70s,
destabilization is occurring rapidly with over 1500 J/kg of MLCAPE
estimated by the latest mesoanalysis. The deep-layer shear is also
maximized across this area with around 40 knots estimated by local
VWPs. Given sufficient shear and instability, supercells capable of
producing large hail will be possible. Rising heights/temperatures
aloft may limit overall storm coverage, but convective trends will
be monitored for the possibility of a severe thunderstorm watch.
