   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 85
   NWS Storm Prediction Center Norman OK
   315 PM CDT Sun Mar 26 2017

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Southern Kansas

   * Effective this Sunday afternoon and evening from 315 PM until
     1100 PM CDT.

   * Primary threats include...
     Isolated very large hail events to 2 inches in diameter possible
     Isolated damaging wind gusts to 70 mph possible
     A tornado or two possible

   SUMMARY...Initially this afternoon, increasing elevated storms may
   pose some severe hail risk across south-central toward southeast
   Kansas. Additional near-surface-based storms are expected to develop
   by late afternoon and early evening farther west across southern
   Kansas in vicinity of a warm front. Severe hail and locally damaging
   winds are expected to be the main risks, although a tornado cannot
   be ruled out early this evening immediately near the Kansas/Oklahoma
   border vicinity as low-level moisture continues to increase.

   The severe thunderstorm watch area is approximately along and 25
   statute miles north and south of a line from 40 miles west of
   Medicine Lodge KS to 95 miles east of Wichita KS. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU5).

   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 450. Mean storm motion vector
   23025.
