URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 335

NWS Storm Prediction Center Norman OK

510 PM CDT Thu Jun 15 2017



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  West/southwest Texas



* Effective this Thursday afternoon from 510 PM until Midnight

  CDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 3

    inches in diameter possible

  Isolated damaging wind gusts to 70 mph possible



SUMMARY...As at least isolated stronger storms develop across the

region through early evening, modest deep-layer winds in conjunction

with strong heating and moderate buoyancy will support some

high-based severe thunderstorms including a few supercells. Large

hail should be the main risk, although a hot/deeply mixed

environment could support severe-caliber downdrafts.



The severe thunderstorm watch area is approximately along and 65

statute miles east and west of a line from 60 miles north northeast

of Big Spring TX to 25 miles south southeast of Fort Stockton TX.

For a complete depiction of the watch see the associated watch

outline update (WOUS64 KWNS WOU5).



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.
