   Areas affected...Portions of northern Mid-Atlantic into parts of
   northern New England

   Concerning...Tornado Watch 517...

   Valid 102053Z - 102230Z

   The severe weather threat for Tornado Watch 517 continues.

   SUMMARY...The tornado risk will continue in WW 517, particularly
   near the effective warm front. A new tornado watch is possible into
   New Hampshire and far western Maine.

   DISCUSSION...Discrete supercells continue to move through
   central/eastern New York and into Vermont. A few weaker, but
   rotating, cells have developed southwest of Burlington, VT,
   recently. Discrete storms, particularly those near the effective
   warm front, will pose the greatest risk of a tornado in addition to
   damaging winds. Regional VAD winds from central/eastern New York
   into Vermont show improved low-level shear over the last couple of
   hours. While destabilization has been a bit more modest into New
   Hampshire/western Maine, there is a possibility that severe storms
   will progress into these areas this evening. With continued
   mid-level ascent and a strengthening low-level jet, a tornado watch
   will need to be considered farther east from WW 517.
