The NWS Storm Prediction Center has issued a

  Maine
  New Hampshire

* Effective this Thursday morning and evening from 1040 AM until
  600 PM EDT.

* Primary threats include...

  Scattered large hail and isolated very large hail events to 2
    inches in diameter possible

SUMMARY...Thunderstorm coverage is expected to increase across the
region over the next few hours, with multiple rounds of storms
possible. Environmental conditions support supercells capable of
large hail with the initial more discrete development. With time, a
trend towards a more linear mode is anticipated. As this occurs, the
primary hazard will transition from large hail to damaging gusts.

The severe thunderstorm watch area is approximately along and 80
statute miles east and west of a line from 45 miles north of Houlton
ME to 35 miles southwest of Portsmouth NH. For a complete depiction
of the watch see the associated watch outline update (WOUS64 KWNS
