FIRE WEATHER PLANNING FORECAST FOR WESTERN MAINE AND NEW HAMPSHIRE
NATIONAL WEATHER SERVICE GRAY ME
239 PM EDT WED APR 22 2026
DISCUSSION
SHOWERY WEATHER PERSISTS THROUGH TONIGHT, BUT WETTING RAINS ARE
UNLIKELY. DRY WEATHER RETURNS TO PARTS OF THE AREA THURSDAY, WITH
MINIMUM RELATIVE HUMIDITY FALLING TO NEAR 30 PERCENT ACROSS
SOUTHERN ZONES. IT WILL ALSO BE BREEZY, WITH NORTHWEST WINDS
GUSTING 20 TO 30 MPH. CLOUDS MAY PERSIST MUCH OF THE DAY ACROSS
THE KENNEBEC RIVER VALLEY AND KEEP TEMPERATURES COOLER AND
RELATIVE HUMIDITY HIGHER.
A STRETCH OF MOSTLY DRY WEATHER IS THEN FORECAST THROUGH THE
WEEKEND INTO EARLY NEXT WEEK. WHILE DRY, SURFACE WINDS AND MIXING
APPEAR TO REMAIN LIGHT. THE BETTER CHANCE FOR THE NEXT WIDESPREAD
RAINFALL IS TOWARD THE MIDDLE OF NEXT WEEK.
