URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 361
NWS Storm Prediction Center Norman OK
1240 AM CDT Sun Jul 12 2020
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
South central Oklahoma
* Effective this Sunday morning from 1240 AM until 400 AM CDT.
* Primary threats include...
Scattered damaging winds and isolated significant gusts to 75
mph likely
Scattered large hail and isolated very large hail events to 2
inches in diameter possible
SUMMARY...Clusters of severe storms with a history of 65-80 mph
measured wind gusts will continue to surge east-southeastward across
south central and parts of southeast Oklahoma, along an outflow
boundary trailing northwestward from a separate cluster of storms in
far southeast Oklahoma. Given the strong instability still
remaining over southern Oklahoma, the threat for additional severe
gusts should persist for another few hours before the storms weaken
near the Red River.
The severe thunderstorm watch area is approximately along and 40
statute miles north and south of a line from Fort Sill OK to 35
miles south of Mcalester OK. For a complete depiction of the watch
see the associated watch outline update (WOUS64 KWNS WOU1).
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.
&&
OTHER WATCH INFORMATION...CONTINUE...WW 360...
AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 65 knots. A
few cumulonimbi with maximum tops to 600. Mean storm motion vector
30035.
