Fire Weather Planning Forecast for Western Maine and New Hampshire
National Weather Service Gray ME
314 AM EDT Thu Aug 21 2025

.DISCUSSION...
Dry today and Friday with full sun expected. Easterly breeze
today keep RH values from dropping much lower than 40-50 percent.
Lower RH values and greater winds arrive Friday with 30-40 percent
on a NNE wind gusting 15-20 mph at times. These gusts are most
likely along the coast and interior, not as strong towards the
mountains and foothills.

Tightening pressure gradient into the weekend will bring the
chance for greater gusts into Sunday. Gusts up to 30 mph will be
possible along the coast and interior. This will be ahead of
incoming rain showers with a slow moving cold front. This will be
the next chance of wetting rain for the forecast area as it
passes Sunday night into Monday.
