   Areas affected...Parts of southern/eastern ME

   Concerning...Severe Thunderstorm Watch 292...

   Valid 231929Z - 232100Z

   The severe weather threat for Severe Thunderstorm Watch 292
   continues.

   SUMMARY...Some threat for hail and damaging wind will spread
   eastward through the afternoon.

   DISCUSSION...A line of strong to potentially severe thunderstorms is
   ongoing from southern into northeast Maine this afternoon. The
   immediate downstream environment remains somewhat favorable for
   organized convection, with MLCAPE approaching 1000 J/kg and modestly
   favorable deep-layer shear (as noted on the 17Z/18Z CAR/GYX modified
   soundings and regional VWPs), and some threat for hail and damaging
   wind will continue into late afternoon. 

   With cooler onshore flow noted over the Downeast Maine vicinity,
   some weakening will be possible with time as storms move into this
   region. However, sufficient elevated buoyancy may still support some
   threat for isolated marginal hail and/or a strong/damaging gust
   before storms move offshore. Isolated storm redevelopment also
   remains possible into southern ME behind the outflow, though at this
   time any severe threat with this redevelopment is currently expected
   to remain marginal and isolated.
