FNUS51 KGYX 180625 FWFGYX Fire Weather Planning Forecast for Western Maine and New Hampshire National Weather Service Gray ME 225 AM EDT Mon May 18 2026 .DISCUSSION... A few showers are possible across central and northern NH and into the western ME mountains this morning and early afternoon, but dry conditions are expected elsewhere. NH is expected to reach the 70s and 80s while onshore flow keeps western Maine in the 60s and 70s. Tuesday and Wednesday will be hot and breezy with temperatures well into the 80s, possibly low 90s in southern NH on Tuesday, but increasing dewpoints ahead of a front should keep RH more in the 35 to 50 percent range. The front will also bring a chance of storms on both Tuesday and Wednesday afternoons with localized wetting rains possible. Cooler and drier conditions will follow the front for Thursday and Friday.
