Fire Weather Planning Forecast for Western Maine and New Hampshire
National Weather Service Gray ME
500 AM EDT Sun Aug 10 2025
.DISCUSSION...
High pressure remains in control, and for the foreseeable future
the weather should remain mostly dry as a result. Aside from some
isolated showers in the mountains today and Monday, which may
bring very localized wetting rains in the mountains, the rest of
the area should see continued drying. A cold front may bring
slightly better chances for precipitation Wednesday into
Thursday.
Daytime relative humidity values between 30 and 50 percent are
expected through early this week with a prolonged period of hot
temperatures starting today.
