URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 133

NWS Storm Prediction Center Norman OK

930 PM CDT Tue May 29 2018



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Parts of western, central, and northern Oklahoma



* Effective this Tuesday night and Wednesday morning from 930 PM

  until 400 AM CDT.



* Primary threats include...

  Scattered large hail likely with isolated very large hail events

    to 2 inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible



SUMMARY...Scattered severe storms are ongoing in clusters across

northwest and west central Oklahoma.  These storms will likely

persist and spread eastward through the overnight hours with an

attendant threat for large hail, especially with embedded

supercells.  There is still some potential for the storms in

northwest Oklahoma to grow into a somewhat larger cluster, which

would favor an increase in the threat for damaging winds.



The severe thunderstorm watch area is approximately along and 80

statute miles east and west of a line from 25 miles northwest of

Ponca City OK to 35 miles west southwest of Chickasha OK. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU3).



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.
