   Areas affected...southern New England

   Concerning...Severe Thunderstorm Watch 471...

   Valid 300148Z - 300345Z

   The severe weather threat for Severe Thunderstorm Watch 471
   continues.

   SUMMARY...While isolated strong wind gusts remain possible, the
   severe threat is expected to wane over the next 1-2 hours. As such,
   additional watches are unlikely.

   DISCUSSION...The segmented line of storms persists into southern New
   England, but a weakening trend has been observed. Objective analysis
   shows increasing MLCIN ahead of these storms, and this should help
   to limit the severe threat as the storms continue east. 

   The 00Z OKX and CHH soundings both show around -50 MLCIN, with
   stronger values over RI and Cape Cod. Given the veering winds aloft,
   marginal low-level convergence and time of day, these storms are not
   expected to require any additional downstream watches.
