URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 206

NWS Storm Prediction Center Norman OK

220 PM MDT Sat Jun 23 2018



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  East central and southeast Colorado

  Western Kansas

  Extreme northeast New Mexico

  The extreme western Oklahoma Panhandle



* Effective this Saturday afternoon and evening from 220 PM until

  900 PM MDT.



* 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...Ongoing thunderstorms from Limon to Goodland should expand

some in coverage and intensify the remainder of the afternoon, with

some potential for storms to coalesce into a cluster and move

southeastward this evening.  The initial threat will be large hail

with splitting supercells, while the threat for damaging winds

should increase this evening as a cluster forms.  Farther south,

more isolated storms could form east of the high terrain.  Any

sustained storms will likely be supercells capable of producing

large hail for a few hours this afternoon/evening.



The severe thunderstorm watch area is approximately along and 75

statute miles east and west of a line from 25 miles west northwest

of Burlington CO to 30 miles south of Springfield CO. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU6).



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.



&&



OTHER WATCH INFORMATION...CONTINUE...WW 205...



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

2 inches. Extreme turbulence and surface wind gusts to 60 knots. A

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

29025.
