URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 193

NWS Storm Prediction Center Norman OK

700 PM MDT Tue Jun 19 2018



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Southeast Colorado



* Effective this Tuesday night from 700 PM until Midnight MDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 2.5

    inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible

  A tornado or two possible



SUMMARY...This watch replaces earlier Tornado Watch 191. At least

isolated severe storms will continue to move generally eastward

across southeast Colorado this evening as a broader convective

system likely evolves from far eastern Colorado into western Kansas.

The tornado risk has largely diminished, but the potential for

isolated large hail and locally severe winds continues. 66 mph winds

were recently (0025Z) measured at La Junta, Colorado.



The severe thunderstorm watch area is approximately along and 60

statute miles east and west of a line from 30 miles southwest of

Springfield CO to 30 miles north northeast of La Junta 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.
