...NORTHERN/EASTERN MAINE 2023 SPRING CLIMATE NARRATIVE...

SPRING (MARCH THROUGH MAY) FINISHED WITH ABOVE AVERAGE TEMPERATURES,
BELOW AVERAGE PRECIPITATION, AND SLIGHTLY ABOVE AVERAGE SNOWFALL.

TEMPERATURES FOR THE 3-MONTH PERIOD AVERAGED FROM 1.5 TO JUST OVER 2
DEGREES ABOVE THE 30-YEAR AVERAGE.  MARCH AND APRIL BOTH FEATURED
ABOVE AVERAGE TEMPERATURES AND MAY FINISHED WITH NEAR AVERAGE TO
SLIGHTLY BELOW AVERAGE TEMPERATURES.  IN CARIBOU IT TIED WITH 1977
FOR THE 9TH WARMEST SPRING ON RECORD.  IN HOULTON IT TIED WITH 1973
AND 2021 FOR THE 10TH WARMEST SPRING.  IN MILLINOCKET, IT TIED WITH
1979 AS THE 11TH WARMEST SPRING ON RECORD, AND FINALLY IN BANGOR IT
TIED WITH 2006 AND PREVIOUS YEARS AS THE 15TH WARMEST SPRING ON
RECORD.

PRECIPITATION WAS BELOW AVERAGE WITH PRECIPITATION (RAIN AND MELTED
SNOW) DEFICITS OF 2.5 TO 3.5 INCHES ACROSS THE REGION.  SNOWFALL WAS
CLOSER TO AVERAGE, AND THAT WAS MAINLY DUE TO ABOVE AVERAGE SNOWFALL
IN MARCH. SNOWFALL WAS BELOW AVERAGE ACROSS THE REGION IN APRIL.

MARCH HAD ABOVE AVERAGE TEMPERATURES AS WELL AS ABOVE AVERAGE
SNOWFALL ACROSS THE REGION. THERE WAS A LACK ON ARCTIC AIR WITH ONLY
ONE NIGHT THE ENTIRE MONTH WITH A LOW BELOW ZERO IN CARIBOU. THE LOW
FOR THE ENTIRE MONTH WAS +10F IN BANGOR.  ALTHOUGH NOT A RECORD,
TYPICALLY BANGOR WILL HAVE ONE OR TWO NIGHTS WITH A LOW BELOW ZERO.

APRIL HAD ABOVE AVERAGE TEMPERATURES AND BELOW AVERAGE PRECIPITATION
AND SNOWFALL. THE FIRST REAL MILD DAY OF THE SPRING OCCURRED ON THE
10TH WITH HIGHS IN MOST AREAS AWAY FROM THE COAST IN THE 60S. ALL
LONG TERM CLIMATE SITES HAD BOTH BELOW AVERAGE PRECIPITATION AND
SNOWFALL. WHAT LITTLE SNOW THAT DID FALL WAS MOSTLY OBSERVED DURING
THE FIRST WEEK OF THE MONTH.

MAY WAS THE ONLY MONTH DURING THE SPRING OF 2023 WITH NEAR TO
SLIGHTLY BELOW AVERAGE TEMPERATURES.  THE WARMEST WEATHER OF THE
MONTH OCCURRED ON THE VERY LAST DAY OF MAY WHEN MANY INLAND AREAS
TOPPED 90 DEGREES.  THE LAST SNOW SHOWERS AND FLURRIES OF THE SEASON
WERE OBSERVED ACROSS NORTHERN AREAS ON THE 17TH WHEN IT WAS
UNSEASONABLY COOL AND BLUSTERY.
