URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 221

NWS Storm Prediction Center Norman OK

535 PM CDT Sun May 24 2020



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  North central into southwest Kansas

  Extreme south central Nebraska



* Effective this Sunday afternoon from 535 PM until Midnight CDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 2

    inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible



SUMMARY...Thunderstorm development is expected along a stalled front

from south central Nebraska into southwest Kansas, as well as along

a remnant dryline extending northward into southwest Kansas, and a

residual outflow boundary across central Kansas.  The storm

environment primarily favors a mix of multicell clusters and a

low-end supercell threat, with storms capable of producing large

hail and damaging winds.  Isolated supercells in southeast Colorado

could eventually move into far southwest Kansas later this evening.



The severe thunderstorm watch area is approximately along and 65

statute miles east and west of a line from 50 miles north northwest

of Concordia KS to 5 miles east southeast of Liberal KS. 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.
