Fire Weather Planning Forecast for Western Maine and New Hampshire
National Weather Service Gray ME
500 PM EDT Thu Aug 21 2025
.DISCUSSION...
Dry conditions continue through Friday with full sun expected.
Lower RH values and greater winds arrive Friday with 30 to 40
percent over most of the interior 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.
