  1100 PM CDT.

* Primary threats include...
  A couple tornadoes possible
  Widespread large hail and scattered very large hail events to 3
    inches in diameter likely
  Scattered damaging winds likely with isolated significant gusts
    to 75 mph possible

SUMMARY...Discrete supercells developing along a remnant boundary
will pose a primary risk of very large hail through mid-evening. A
broader MCS will likely develop during the evening, increasing the
risk for damaging winds near to after sunset.

north and south of a line from 80 miles northwest of Abilene TX to
60 miles north northeast of Abilene TX. For a complete depiction of
the watch see the associated watch outline update (WOUS64 KWNS

Tornado Watch Number 182
NWS Storm Prediction Center Norman OK
300 PM CDT Mon May 17 2021

The NWS Storm Prediction Center has issued a

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

* Effective this Monday afternoon and evening from 300 PM until
  1100 PM CDT.

* Primary threats include...
  A few tornadoes possible
  Widespread large hail and scattered very large hail events to 4
    inches in diameter likely
  Scattered damaging winds and isolated significant gusts to 75
    mph possible

SUMMARY...Intense supercells are expected to develop by late
afternoon within an environment characterized by strong instability
and moderate-strength winds through a deep layer. This development
is initially expected along the New Mexico/Texas border, and
southward into the Trans Pecos/Rio Grande vicinity on a more
isolated basis. Very large hail should be the most common hazard,
but a couple of tornadoes are also possible, particularly near a
residual boundary that influences the New Mexico/Texas border
vicinity of the south Texas Plains. Damaging wind potential may also
increase by around mid-evening as storms congeal/organize.

The tornado watch area is approximately along and 75 statute miles
east and west of a line from 70 miles north northeast of Cannon Afb
NM to 60 miles east of Dryden TX. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU2).

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.

140 PM MDT Mon May 17 2021

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Southeast Colorado

  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...Severe thunderstorms will continue to increase initially
near/just east of the mountains across northeast New Mexico and
southeast Colorado, with other development possible later this
afternoon near a boundary extending into the Oklahoma/Texas
Panhandles. A combination of multicells and some supercells will be
capable of large hail and possibly a tornado. Damaging wind
potential may also increase by early evening, especially into the
Texas/Oklahoma Panhandles where the severe risk will persist much of
the evening.

The severe thunderstorm watch area is approximately along and 135
statute miles east and west of a line from 55 miles north of
Trinidad CO to 70 miles southwest of Dalhart 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.

weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.
