FIRE WEATHER PLANNING FORECAST FOR WESTERN MAINE AND NEW HAMPSHIRE
NATIONAL WEATHER SERVICE GRAY ME
244 PM EDT TUE APR 21 2026
DISCUSSION
VERY DRY AFTERNOON WILL GIVE WAY TO STRONG RELATIVE HUMIDITY
RECOVERY OVERNIGHT. WEDNESDAY WILL BRING A CHANCE FOR RAIN OR SNOW
SHOWERS BACK TO THE FORECAST. WHILE I DO NOT EXPECT A WETTING RAIN
FOR THE MAJORITY OF THE AREA, IT DOES LOOK LIKE A PRETTY RAW AND
POSSIBLY DAMP SPRING DAY. DRY WEATHER RETURNS TO PARTS OF THE AREA
THURSDAY, WITH MINIMUM RELATIVE HUMIDITY FALLING TO NEAR 30 PERCENT
ACROSS SOUTHERN ZONES. CLOUDS MAY PERSIST MUCH OF THE DAY ACROSS THE
KENNEBEC RIVER VALLEY AND KEEP TEMPERATURES COOLER AND RELATIVE
HUMIDITY HIGHER.
