Service.

Please contact our office at (207) 688-3224, if you have questions
or concerns with this forecast.

Showers will continue to be light through noon, with little chance
of enough for a wetting rain. Forecast trends continue to be
lighter, with greatest rainfall amounts north of the Whites.
Otherwise, light winds with RH values 60 to 70 percent in the
morning. Additional shower chances remain during the early
afternoon, but less widespread. A cold front drops out of Quebec
after noon, causing a W to NW wind shift around 2 or 3pm. Winds
increase, as well as gust frequency. Gusts may exceed 30 mph at
times, with RH falling into lower 50 percent. Much cooler tonight,
with surface inversion much higher than last night. This should
promote breeze to continue tonight, but not as gusty as this
afternoon. A much drier day Thursday, but winds remain light. RH
values fall into the 20s, but could also see areas of teens by
afternoon time.
