   Concerning...Severe Thunderstorm Watch 85...

   Valid 012040Z - 012245Z

   The severe weather threat for Severe Thunderstorm Watch 85
   continues.

   SUMMARY...Convection should continue along the stationary boundary
   and near outflow from earlier storms. Isolated large hail and wind
   damage are the main hazards with this activity.

   DISCUSSION...A majority of the activity within WW 85 remains near
   and south of a stationary front north of the Ohio River. An
   additional cluster persists in southern West Virginia. Thus far,
   storms have maintained a primarily cellular mode and produce
   isolated large hail. The expectation for the remainder of the
   afternoon is for additional storms to move into the watch from the
   west as well as other storms potentially developing along outflow
   from storms in West Virginia. The cluster in southern West Virginia
   is likely to weaken as it moves into the terrain as temperatures
   there are slightly cooler and convection has influenced the airmass
   farther east. Regional VAD data shows 40-50 kts of 0-6 km shear
   which should continue to support organized storms capable of
   primarily isolated large hail and wind damage.
