FIRE WEATHER PLANNING FORECAST FOR WESTERN MAINE AND NEW HAMPSHIRE
NATIONAL WEATHER SERVICE GRAY ME
320 AM EDT TUE APR 21 2026
DISCUSSION
REMAINING COOL TODAY. DEWPOINTS WILL MIX INTO THE SINGLE DIGITS
ACROSS THE INTERIOR AND RESULT IN MINIMUM RELATIVE HUMIDITY
VALUES BETWEEN 20 TO 25 PERCENT OVER A LARGE PORTION OF THE
INTERIOR. THANKFULLY WINDS WILL BE RATHER LIGHT. THE EXCEPTION
WILL BE BEHIND THE SEA BREEZE FRONT, BUT IT WILL ALSO COME WITH
RELATIVE HUMIDITY RISING TO MODERATE LEVELS. AFTER A CHANCE OF
LIGHT PRECIPITATION WEDNESDAY AND THURSDAY, FRIDAY LOOKS TO BE
BOTH BREEZIER AND DRIER.
