URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 306

NWS Storm Prediction Center Norman OK

110 PM MDT Fri Jun 26 2020



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Eastern Colorado



* Effective this Friday afternoon and evening from 110 PM until

  900 PM MDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 2

    inches in diameter likely

  Scattered damaging wind gusts to 70 mph possible

  A tornado or two possible



SUMMARY...Scattered thunderstorms are expected to form along the

Front Range this afternoon, and spread east-southeastward over the

eastern plains through this evening.  More discrete supercells are

expected initially, with the threat for large hail.  Upscale growth

into clusters later this afternoon/evening will support an increase

in the threat for damaging winds.  An isolated tornado cannot be

ruled out with the initial storms, especially near the Palmer

Divide.



The severe thunderstorm watch area is approximately along and 75

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

of Akron CO to 50 miles west southwest 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.
