455 AM CDT Fri May 22 2020
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Central and eastern Oklahoma

* Primary threats include...
Scattered damaging winds likely with isolated significant gusts
to 80 mph possible
A tornado or two possible
SUMMARY...This watch adjoins the extended portion of watch 200. An
MCS, with a well-developed cold pool and theta-e/pressure
perturbation, will move east-southeastward on either side of an
instability gradient accompanying a warm-frontal zone. Multiple
Oklahoma Mesonet stations have measured severe winds with this
complex in the last 1-2 hours. Sporadic gusts above severe limits
remain possible as this complex forward-propagates into eastern
Oklahoma.
The severe thunderstorm watch area is approximately along and 70
statute miles either side of a line from 20 miles west northwest of
Chandler OK to 50 miles southeast of Muskogee 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 200...
AVIATION...A few severe thunderstorms with hail surface and aloft to
1 inch. Extreme turbulence and surface wind gusts to 70 knots. A few
cumulonimbi with maximum tops to 550. Mean storm motion vector
29045.
