URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 391

NWS Storm Prediction Center Norman OK

145 PM MDT Mon Jun 17 2019



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  Central and eastern New Mexico

  Western Oklahoma Panhandle

  West Texas



* Effective this Monday afternoon and evening from 145 PM until

  900 PM MDT.



* Primary threats include...

  Scattered large hail likely with isolated very large hail events

    to 2 inches in diameter possible

  Isolated damaging wind gusts to 70 mph possible



SUMMARY...Isolated strong to severe thunderstorms will continue to

increase, initially from interior central New Mexico to the eastern

New Mexico plains, as well as across far southwest Texas. These

storms will eventually drift into other parts of west Texas and the

Oklahoma Panhandle by early evening. A very moist/unstable

environment and modest deep-layer shear will support

supercells/sustained multicells capable of large hail along with

severe-caliber wind gusts.



The severe thunderstorm watch area is approximately along and 110

statute miles east and west of a line from 20 miles north northeast

of Raton NM to 35 miles south southwest of Marfa TX. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU1).



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.



&&



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

29020.
