   Severe Thunderstorm Watch Number 144
   NWS Storm Prediction Center Norman OK
   555 PM CDT Fri Apr 22 2022

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Exrtreme eastern Colorado
     Western Kansas
     Extreme southwestern Nebraska

   * Effective this Friday afternoon and Saturday morning from 555
     PM until 100 AM CDT.

   * Primary threats include...
     Scattered damaging winds and isolated significant gusts to 75
       mph likely
     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter likely
     A tornado or two possible

   SUMMARY...Thunderstorms will continue to develop north-northeastward
   into western Kansas this evening along a dryline, where the storm
   environment favors supercells with very large hail up to tennis ball
   size (2.5 inch diameter), and thunderstorm outflow gusts up to 75
   mph, and perhaps a tornado late this evening.  Toward about 11pm to
   1am CDT, the dryline will retreat to near or west of the
   Colorado/Kansas border, with additional thunderstorm development in
   a line expected.  Damaging winds and large hail will be the main
   threats with these storms, though an isolated tornado may occur with
   embedded circulations in the line.

   The severe thunderstorm watch area is approximately along and 55
   statute miles east and west of a line from 35 miles west northwest
   of Mccook NE to 30 miles west of Liberal KS. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU4).


   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



   AVIATION...A few severe thunderstorms with hail surface and aloft to
   2.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A
   few cumulonimbi with maximum tops to 500. Mean storm motion vector
