   430 PM EDT Sat Mar 17 2018

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Central and Eastern Kentucky
     Far Western North Carolina
     Northern and Eastern Tennessee
     Far Western Virginia
     Far Southern West Virginia

   * Effective this Saturday afternoon from 430 PM until Midnight
     EDT.

   * Primary threats include...
     Scattered large hail likely with isolated very large hail events
       to 2 inches in diameter possible

   SUMMARY...Clusters of storms including supercells will continue to
   increase through late afternoon especially across central/eastern
   Kentucky, with somewhat more isolated development expected southward
   into Tennessee. Bouts of severe hail will be common with the most
   intense storms, while damaging winds can also be expected,
   especially if a semi-organized linear system evolves by early
   evening toward the spine of the Appalachian Mountains.

   The severe thunderstorm watch area is approximately along and 65
   statute miles north and south of a line from 75 miles west of London
   KY to 35 miles east northeast of Bristol TN. For a complete
   depiction of the watch see the associated watch outline update
   (WOUS64 KWNS WOU0).

   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.
