URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 213

NWS Storm Prediction Center Norman OK

255 PM MDT Sun Jun 24 2018



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Parts of east central and southeast Colorado



* Effective this Sunday afternoon and evening from 255 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...A gradual increase in thunderstorm coverage and intensity

is expected through the afternoon/evening across east central and

southeast Colorado as a midlevel trough approaches from the west and

the low levels recover from the effects of prior convection.  The

storm environment will support supercells capable of producing large

hail with the initial storms, and there will be some potential for

upscale growth into a more linear cluster with some damaging wind

threat by this evening.



The severe thunderstorm watch area is approximately along and 70

statute miles east and west of a line from 60 miles north of La

Junta CO to 40 miles west southwest of Springfield CO. For a

complete depiction of the watch see the associated watch outline

update (WOUS64 KWNS WOU3).



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.
