URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 317

NWS Storm Prediction Center Norman OK

500 PM CDT Fri Jul 27 2018



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Western Kansas



* Effective this Friday afternoon and Saturday morning from 500

  PM until 200 AM CDT.



* Primary threats include...

  Widespread damaging winds likely with isolated significant gusts

    to 80 mph possible

  Scattered large hail likely with isolated very large hail events

    to 2.5 inches in diameter possible

  A tornado or two possible



SUMMARY...Isolated severe thunderstorms including a few supercells

are initially expected this evening across west-central and

north-central Kansas with large hail possible and possibly even a

tornado. Storms should continue to develop/increase and eventually

cluster later this evening with the possible evolution of a

south/southeastward-accelerating linear convective system. If this

occurs, a considerable risk for damaging thunderstorm winds would

exist across a broad part of southwest Kansas.



The severe thunderstorm watch area is approximately along and 70

statute miles north and south of a line from 65 miles west of Garden

City KS to 55 miles south southeast of Russell 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.
