Fire Weather Planning Forecast for Western Maine and New Hampshire
National Weather Service Gray ME
500 AM EDT Fri Apr 18 2025

.DISCUSSION...
Winds will remain breezy out of the south, but not as gusty as
Thursday. Mixing will again bring a dry late morning and
afternoon
with RH values across much of the interior falling to 20to
25 percent
with immediate coastal areas not falling as much due to moist
onshore
flow. Shower chances increase this evening through Saturday, but
confidence in location of wetting rains is low. Showers or
periods
of rain may fall across southern ME and central NH tonight.
Greater confidence in wetting rainfall remains in the mountains.
Dry weather returns Sunday and Monday, before another chance for
rainfall Monday night into Tuesday.
