URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 495

NWS Storm Prediction Center Norman OK

1240 PM MDT Sat Jul 6 2019



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Northeast Colorado

  The western Nebraska Panhandle

  Southeast Wyoming



* Effective this Saturday afternoon and evening from 1240 PM

  until 900 PM MDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 2.5

    inches in diameter likely

  Scattered damaging wind gusts to 70 mph possible

  A tornado or two possible



SUMMARY...Scattered thunderstorm development appears to be underway

along the Front Range from northeast Colorado into southeast

Wyoming.  The environment east of the mountains will favor splitting

supercells capable of producing isolated very large hail, and

perhaps a tornado with the more dominant right-moving storms.

Otherwise, some clustering of storms will be possible later this

evening farther east toward the Nebraska Panhandle, with an

attendant threat for a few severe gusts.



The severe thunderstorm watch area is approximately along and 75

statute miles east and west of a line from 40 miles east northeast

of Douglas WY to 25 miles west of Limon CO. For a complete depiction

of the watch see the associated watch outline update (WOUS64 KWNS

WOU5).



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.
