Fire Weather Planning Forecast for Western Maine and New Hampshire
National Weather Service Gray ME
144 AM EDT Thu Jul 17 2025

.DISCUSSION...
It will be one more day of hot and humid weather before a cold
front crosses the region and ushers in some drier air. Scattered
showers and thunderstorms will be possible with the front, but
widespread wetting rains do not appear very likely. The dry
conditions Friday will gradually give way to warmer and more humid
weather by the Sunday and Monday timeframe.
