Fire Weather Planning Forecast for Western Maine and New Hampshire
National Weather Service Gray ME
501 PM EDT Wed Aug 27 2025
.DISCUSSION...
Scattered showers and a couple of storms are expected this
afternoon mostly across southern and coastal areas, with only
isolated wetting rains possible. Drier conditions are expected
Thursday with light southerly winds, but winds may gust to around
20 mph along the coast in the afternoon as the seabreeze moves
inland. Min RH is expected to fall to 30 to 40 percent for most
areas on Thursday. A low pressure and frontal boundary approach
the area on Friday with higher coverage of showers and better
chances for wetting rains over a larger area.
