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.
