   Severe Thunderstorm Watch Number 181
   NWS Storm Prediction Center Norman OK
   140 PM MDT Mon May 17 2021

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Southeast Colorado
     Northeast New Mexico
     Oklahoma Panhandle
     Texas Panhandle

   * Effective this Monday afternoon and evening from 140 PM until
     1000 PM MDT.

   * Primary threats include...
     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.
   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
   2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
   24015.

Please visit the National Weather Service Interactive Weather Information Network (IWIN) for more information on the warnings.

For each watch, probabilities for particular events inside the watch (listed above in each table) are determined by the issuing forecaster. The "Low" category contains probability values ranging from less than 2% to 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities), "Moderate" from 30% to 60%, and "High" from 70% to greater than 95%. High values are bolded and lighter in color to provide awareness of an increased threat for a particular event.
