URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 290

NWS Storm Prediction Center Norman OK

200 PM CDT Sun Jun 21 2020



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Western and Central Kansas



* Effective this Sunday afternoon and evening from 200 PM until

  1000 PM CDT.



* Primary threats include...

  Widespread large hail and isolated very large hail events to 3.5

    inches in diameter likely

  Widespread damaging winds likely with isolated significant gusts

    to 80 mph possible

  A tornado or two possible



SUMMARY...Severe thunderstorms are expected to rapidly develop and

increase in coverage initially across west-central/north-central

Kansas, and by late afternoon across southwest Kansas. Intense

supercells capable of very large hail can be expected. Low-level

winds will remain weak, but a tornado cannot be entirely ruled out.

The potential for widespread damaging winds/wind-driven damaging

hail will steadily increase by early evening as storms accelerate

southeastward across southwest/south-central Kansas.



The severe thunderstorm watch area is approximately along and 85

statute miles north and south of a line from 30 miles northeast of

Hutchinson KS to 50 miles west northwest of Garden City KS. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU0).



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.



&&



AVIATION...A few severe thunderstorms with hail surface and aloft to

3.5 inches. Extreme turbulence and surface wind gusts to 70 knots. A

few cumulonimbi with maximum tops to 550. Mean storm motion vector

30025.
