   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Far Southeast Indiana
     Far Northern Kentucky
     Central and Southern Ohio
     Southwest Pennsylvania
     West Virginia

   * Effective this Tuesday afternoon and evening from 110 PM until

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph likely
     Scattered large hail events to 1.5 inches in diameter possible
     A tornado or two possible

   SUMMARY...Thunderstorm coverage is expected to increase this
   afternoon as a pre-frontal trough and associated cold front moves
   through the region. Overall environmental conditions favor strong to
   severe thunderstorms, with a linear convective mode favoring
   damaging gusts as the primary risk. Low-level shear is also strong
   enough to support a low-probability risk for a few brief,
   line-embedded tornadoes as well.

   The severe thunderstorm watch area is approximately along and 80
   statute miles north and south of a line from 75 miles north
   northeast of White Sulphur Springs WV to 50 miles west northwest of
   Cincinnati OH. For a complete depiction of the watch see the
   associated watch outline update (WOUS64 KWNS WOU6).

   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.
