URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 204

NWS Storm Prediction Center Norman OK

405 PM CDT Tue May 25 2021



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Western Oklahoma

  West/Northwest Texas



* Effective this Tuesday afternoon and evening from 405 PM until

  1100 PM CDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 2.5

    inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible

  A tornado or two possible



SUMMARY...Multiple corridors of severe thunderstorm development are

expected, most probable near residual outflow and the dryline/front

across west/northwest Texas. While winds through a deep layer are

not overly strong, ample moisture/instability will support some

transient supercells aside from more prevalent multicells. Large

hail will be the primary risk initially. Storms should eventually

cluster and accelerate southeastward across the region this evening

with a large hail/severe wind risk continuing toward the Low Rolling

Plains and west/northwest Texas as well as western Oklahoma.



The severe thunderstorm watch area is approximately along and 80

statute miles east and west of a line from 80 miles northeast of

Borger TX to 45 miles west southwest of San Angelo 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.
