URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 194
NWS Storm Prediction Center Norman OK
1240 PM MDT Sat May 22 2021

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of 
  Eastern New Mexico
  Far West Texas

* Effective this Saturday afternoon and evening from 1240 PM
  until 900 PM MDT.

* Primary threats include...
  A couple tornadoes possible
  Scattered large hail likely with isolated very large hail events
    to 3 inches in diameter possible
  Isolated damaging wind gusts to 70 mph possible

SUMMARY...Severe thunderstorms are expected to develop initially
across a broad portion of eastern New Mexico including the Raton
Mesa vicinity southward toward the Sacramento Mountains. A very
moist environment exists across the region in conjunction with
supercell-favorable wind profiles. Large hail should be the most
common risk, but a couple of tornadoes could also occur given the
moist environment and easterly component of near-surface winds.
Isolated severe-caliber winds may also occur.

The tornado watch area is approximately along and 70 statute miles
east and west of a line from 20 miles northeast of Raton NM to 80
miles south of Guadalupe Pass TX. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU4).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and 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.

&&

OTHER WATCH INFORMATION...CONTINUE...WW 193...

AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 3 inches. Extreme turbulence and surface wind
gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean
storm motion vector 22025.
