   Concerning...Severe Thunderstorm Watch 97...

   Valid 211856Z - 212030Z

   The severe weather threat for Severe Thunderstorm Watch 97
   continues.

   SUMMARY...Threat for damaging wind gusts continues over southern New
   England.

   DISCUSSION...Low-topped convective line continues to move
   eastward/northeastward at 40-45 kt into southern New England. Gusts
   around 40-45 kt have been reported with this line thus far.
   Downstream areas of western/central MA and CT are characterized by
   temperatures in the mid 60s and steep low-level lapse rates (i.e. 7
   to 8 deg C per km from 0-3 km). As such, the expectation is for
   gusts of similar strength (i.e. 40 to 50 kt) to continue as the line
   moves across western/central MA and CT over the next hour or so.

   Some potential exists for the deep convection along the front to
   reach into far southern New Hampshire, with an attendant threat for
   a few damaging wind gusts.
