URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 180

NWS Storm Prediction Center Norman OK

325 PM CDT Wed May 13 2020



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Parts of west central and southwest Texas



* Effective this Wednesday afternoon and evening from 325 PM

  until 1000 PM CDT.



* Primary threats include...

  Scattered large hail likely with isolated very large hail events

    to 2.5 inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible



SUMMARY...Thunderstorms are beginning to develop just east of the

higher terrain in Pecos County, and other storms will likely form

this afternoon farther north along a dryline.  The storm environment

will favor supercells across the southern part of the watch area,

and multicell clusters across the northern part of the watch.  Large

hail will be most probable with any supercells, while damaging winds

will be the main concern with the storm clusters as they spread

eastward through late evening.



The severe thunderstorm watch area is approximately along and 70

statute miles east and west of a line from 90 miles north northeast

of Big Spring TX to 25 miles south southeast of Dryden TX. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU0).



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.
