URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 212

NWS Storm Prediction Center Norman OK

240 PM CDT Sun Jun 24 2018



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  South central and southeast Oklahoma



* Effective this Sunday afternoon and evening from 240 PM until

  800 PM CDT.



* Primary threats include...

  Scattered damaging wind gusts to 70 mph possible

  Isolated large hail events to 1.5 inches in diameter possible



SUMMARY...A long-lived thunderstorm cluster now crossing central

Oklahoma will likely persist through the afternoon as the low levels

destabilize across southern and southeastern Oklahoma in advance of

the storms.  Given recent mesonet observations of 58-74 mph gusts,

the threat for damaging winds should continue for several more

hours.  The strongest storms could also produce isolated large hail.



The severe thunderstorm watch area is approximately along and 35

statute miles north and south of a line from 60 miles west of

Ardmore OK to 50 miles east southeast of Mcalester OK. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU2).



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.



&&



AVIATION...A few severe thunderstorms with hail surface and aloft to

1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A

few cumulonimbi with maximum tops to 550. Mean storm motion vector

29035.
