Fire Weather Planning Forecast for Western Maine and New Hampshire

.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 or storms this afternoon and again Sunday, which
will bring very localized wetting rains in the mountains, the
rest of the area should see continued drying. Daytime relative
humidity values between 30 and 50 percent will gradually creep up
as we move into early next week and moisture increases. A
prolonged period of hot temperatures around 90 will begin Sunday.
