...NORTHERN AND EASTERN MAINE SPRING 2025 CLIMATE NARRATIVE...

METEOROLOGICAL SPRING (MARCH THROUGH MAY) FINISHED WITH TEMPERATURES
RANGING FROM 1.0 TO 2.5 DEGREES (F) ABOVE THE 1991-2020 AVERAGES
ACROSS NORTHERN AND EASTERN MAINE. MARCH FEATURED WELL ABOVE NORMAL
TEMPERATURES. APRIL AND MAY SAW TEMPERATURES NEAR TO SOMEWHAT ABOVE
NORMAL. NO MAJOR CLIMATE SITE FINISHED IN THE TOP 10 WARMEST SPRINGS
ON RECORD OR FOR ANY INDIVIDUAL MONTH FROM MARCH TO MAY.

PRECIPITATION (RAIN AND MELTED SNOWFALL) RANGED FROM 130 TO 170
PERCENT OF NORMAL. CARIBOU SAW 12.97 INCHES OF PRECIPITATION DURING
METEOROLOGICAL SPRING, THE 3RD MOST ON RECORD. THE WETTEST SPRING ON
RECORD IN CARIBOU OCCURRED IN 2005 (14.29 INCHES). RECORDS IN

ALSO THE 3RD MOST ON RECORD. THE WETTEST SPRING ON RECORD IN BANGOR
OCCURRED IN 1983 (24.07 INCHES). RECORDS IN BANGOR BEGIN IN 1925. IN

OF ABOVE NORMAL TEMPERATURES FOR NORTHERN AND EASTERN MAINE. THE CPC
OUTLOOK IS TILTED TOWARDS ABOVE NORMAL RAINFALL FOR THE BANGOR
