URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 200
NWS Storm Prediction Center Norman OK
950 PM CDT Thu May 21 2020
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Southwest and south central Kansas
Northwest and north central Oklahoma and the eastern Oklahoma
Panhandle

Scattered large hail and isolated very large hail events to 2
inches in diameter possible
A tornado or two possible
SUMMARY...Supercell cluster over southwest Kansas is growing upscale
through storm mergers into a larger convective system. The initial
supercell interactions could pose a threat for large hail and
perhaps a tornado through about 04z. Damaging winds will become
more of a threat as the cold pool becomes more established and
storms develop east-southeastward toward northwest Oklahoma
overnight.
The severe thunderstorm watch area is approximately along and 75
statute miles north and south of a line from 30 miles north of
Liberal KS to 40 miles north northeast of Enid OK. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU0).

REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
