URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 153

NWS Storm Prediction Center Norman OK

1250 PM MDT Sun Jun 3 2018



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of

  New Mexico

  Far west Texas



* Effective this Sunday afternoon and evening from 1250 PM until

  900 PM MDT.



* Primary threats include...

  Scattered large hail likely with isolated very large hail events

    to 2 inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible

  A tornado or two possible



SUMMARY...A northeastward-moving upper-level system will provide

ample shear and forcing for ascent, while relatively high moisture

content exists across the region. This scenario will support an

increasing coverage and intensity of storms this afternoon,

including some supercells. Large hail is likely to be the common

hazard, although severe-caliber winds may occur and even a tornado

or two cannot be ruled out given the relatively moist environment.

Storms may eventually form into a complex and spread eastward toward

west Texas this evening.



The severe thunderstorm watch area is approximately along and 100

statute miles east and west of a line from 55 miles north of Cuba NM

to 80 miles south of Guadalupe Pass TX. 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.



&&



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 500. Mean storm motion vector

25020.
