The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of 
  Eastern Arkansas
  Northeastern Louisiana
  The Missouri Bootheel
  Central and northern Mississippi
  Western Tennessee

* Effective this Friday afternoon and evening from 340 PM until
  1100 PM CDT.

* Primary threats include...
  Scattered damaging winds likely with isolated significant gusts
    to 75 mph possible
  Scattered large hail likely with isolated very large hail events
    to 2 inches in diameter possible

SUMMARY...Several convective scenarios are expected in the watch
area, beginning with the continued growth/intensification of a storm
cluster (now crossing southern Arkansas) which will continue
eastward into northwestern Mississippi later this afternoon/evening.
 Additional scattered severe storm development may occur farther
north into northeastern Arkansas and western Tennessee, as well
closer to central Mississippi along an outflow boundary moving
northwestward.  Damaging winds will be the primary severe threat,
especially with the Arkansas storm cluster, though large hail and
damaging gusts will be possible through this evening across the
watch area.

The severe thunderstorm watch area is approximately along and 85
statute miles east and west of a line from 15 miles north of
Dyersburg TN to 90 miles west southwest of Meridian MS. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU0).

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
