URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 94

NWS Storm Prediction Center Norman OK

150 PM CDT Tue Mar 28 2017



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  West-central and southwest Texas



* Effective this Tuesday afternoon and evening from 150 PM until

  1000 PM CDT.



* Primary threats include...

  Scattered large hail likely with isolated very large hail events

    to 3.5 inches in diameter possible



SUMMARY...As the air mass continues to strongly destabilize this

afternoon, strong shear will support increasing potential for

supercells near and just east of the dryline across

west-central/southwest Texas. Very large hail is the main risk. The

number of storms should increase across the region later this

evening with a more widespread severe hail and wind threat evolving,

even beyond the currently scheduled Watch expiration time.



The severe thunderstorm watch area is approximately along and 60

statute miles east and west of a line from 60 miles northwest of

Abilene TX to 55 miles east southeast of Dryden TX. 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.
