   Areas affected...southern NH...much of MA

   Concerning...Severe potential...Watch possible 

   Valid 121950Z - 122045Z

   Probability of Watch Issuance...60 percent

   SUMMARY...A small severe thunderstorm watch is being considered for
   the areas east of an ongoing cluster near the VT/MA/NY border.  This
   activity is expected to move to the I-95 corridor.  Isolated strong
   to severe gusts are possible.

   DISCUSSION...Radar mosaic shows a cluster of storms near the
   VT/MA/NY border as of 345pm.  This activity is located to the east
   of an eastward-moving MCV currently located over central NY.  The
   Albany, NY ASOS recently observed a gust of 39 kt.  The airmass over
   southern New England has warmed into the lower 90s with dewpoints
   generally in the lower 70s.  It appears at least an isolated risk
   for strong to locally severe gusts will materialize east of severe
   thunderstorm watch 432.  The overall coverage of damaging gusts is
   still in question but some risk appears to be increasing through the
   early evening.
