Fire Weather Planning Forecast for Western Maine and New Hampshire
National Weather Service Gray ME
225 PM EDT Mon Sep 7 2026

.DISCUSSION...
No wetting rain expected over most of the area through at least
Wednesday. A weak cold front will drop into the northern parts of
the area tonight and bring a chance of showers. For the areas that
are lucky enough to see rain, it will most likely remain less than
0.10 inches. A better chance will be late Wednesday with the next
cold front, but even that may be more hit and miss. It will dry
out Thursday with gusty northwest winds.
