URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 229

NWS Storm Prediction Center Norman OK

1010 PM CDT Tue May 16 2017



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Southern Kansas

  Western and central Oklahoma

  North Texas



* Effective this Tuesday night and Wednesday morning from 1010 PM

  until 500 AM CDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 2

    inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible

SUMMARY...Semi-discrete severe storms will continue to occur on a

relatively isolated basis, ahead of an increasing band of mostly

linearly organized storms currently increasing across west/northwest

Texas. Bouts of severe hail will remain possible, and a relatively

widespread damaging wind risk may also evolve. A tornado or two

could also occur, mainly with line-embedded circulations that

eventually evolve.



The severe thunderstorm watch area is approximately along and 75

statute miles east and west of a line from 45 miles northwest of

Ponca City OK to 40 miles east southeast of Abilene TX. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU9).



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.
