URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 247
NWS Storm Prediction Center Norman OK
555 PM CDT Wed May 15 2024
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
South-Central Kansas
Western and Northern Oklahoma
* Effective this Wednesday afternoon and Thursday morning from
555 PM until 100 AM CDT.
* Primary threats include...
Scattered damaging winds and isolated significant gusts to 80
mph likely
Scattered large hail and isolated very large hail events to 2.5
inches in diameter likely
A tornado or two possible
SUMMARY...Several clusters of strong to severe thunderstorms are
forecast to develop this evening across western into northern
Oklahoma and into south-central Kansas. The environment will
support a mix of supercells and organized linear clusters. A threat
for large to very large hail will seemingly be greatest through the
mid evening with any supercells. A non-zero risk for a tornado this
evening may focus over far northern Oklahoma and southern Kansas.
By mid to late evening, the risk for severe gusts will likely become
the primary severe hazard.
The severe thunderstorm watch area is approximately along and 90
statute miles north and south of a line from 55 miles northwest of
Clinton OK to 40 miles south southeast of Emporia KS. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU7).
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 245...WW 246...
AVIATION...A few severe thunderstorms with hail surface and aloft to
2.5 inches. Extreme turbulence and surface wind gusts to 70 knots. A
few cumulonimbi with maximum tops to 500. Mean storm motion vector
24035.
