The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
southeast New Mexico
southwest Texas
* effective this Thursday afternoon and evening from 205 PM until
1000 PM CDT.
* Primary threats include...
several damaging wind gusts likely with a few significant gusts
to 80 mph possible
several large hail events with a few very large hail events to 2
inches in diameter possible
The Severe Thunderstorm Watch area is approximately along and 125
statute miles east and west of a line from 15 miles northwest of
Big Spring Texas to 85 miles southwest of Dryden Texas. For a
complete depiction of the watch see the associated watch outline
update (wous64 kwns wou4).
Precautionary/preparedness actions...
Remember... a Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings. Severe thunderstorms can and occasionally
do produce tornadoes.
Other watch information... continue... ww 213...
Discussion... rapid storm development is now underway... across the
mountains of southwest Texas into southeast New Mexico. In the
presence of thermodynamic profiles characterized by very steep
mid-level lapse rates and large cape... vertical shear may be
marginally sufficient for at least short-lived updraft rotation in
strongest storms. Light westerly deep layer mean flow may aid
propagation into parts of the Rio Grande Valley and Edwards
Plateau... as surface cold pools consolidate later this afternoon.
In addition to the risk for large hail... a few strong wind gusts are
probable... both with downbursts and along the outflow gust front.
Aviation... a few severe thunderstorms with hail surface and aloft
to 2 inches. Extreme turbulence and surface wind gusts to 70
knots. A few cumulonimbi with maximum tops to 550. Mean storm
motion vector 27010.
