FIRE WEATHER PLANNING FORECAST FOR WESTERN MAINE AND NEW HAMPSHIRE
NATIONAL WEATHER SERVICE GRAY ME
746 PM EDT TUE APR 28 2026
DISCUSSION
DRIER AIR ALOFT WILL MIX TO THE SURFACE ALONG A SEA BREEZE FRONT
THAT PUSHES INLAND TO THE MOUNTAINS THIS AFTERNOON. EXPECT A
SHARP DROP IN RH AS THIS HAPPENS WITH MIN RH DROPPING TO AROUND 25
PERCENT. THEREFORE, WE COULD SEE SOME ELEVATED FIRE WEATHER
CONCERNS INTO THIS EVENING. THERE WILL BE GOOD HUMIDITY RECOVERY
TONIGHT, WITH MOISTURE CONTINUING TO INCREASE THROUGH WEDNESDAY.
THIS MAY ALLOW FOR SOME AREAS OF DRIZZLE TO DEVELOP, MAINLY ALONG
THE COASTAL PLAIN, BEFORE WIDESPREAD WETTING RAINS MOVE IN LATE
WEDNESDAY NIGHT THROUGH THURSDAY.
