...MAY 2023 CLIMATE NARRATIVE FOR NORTHERN/EASTERN MAINE...

MAY 2023 FOR THE REGION FINISHED WITH NEAR TO SLIGHTLY BELOW AVERAGE
TEMPERATURES AND A LITTLE BELOW AVERAGE FOR TOTAL PRECIPITATION.

AVERAGE TEMPS FOR THE MONTH RANGED FROM NEAR AVERAGE FOR DOWNEAST
AND CENTRAL PORTIONS OF THE REGION TO ONE DEGREE BELOW AVERAGE
ACROSS THE NORTH. TYPICAL FOR MAY, DAY TO DAY TEMPERATURE DEPARTURES
RAN UP AND DOWN DURING THE COURSE OF THE MONTH, WITH ESPECIALLY COOL
SPELLS NOTED DURING THE 16TH THROUGH 18TH AND AGAIN DURING THE 24TH
TO 26TH WHERE DAILY TEMPERATURE DEPARTURES RAN UPWARDS TO 10 TO 15
DEGREES BELOW AVERAGE. MOST LOCATIONS EXPERIENCED THERE LOWEST TEMPS
OF THE MONTH AROUND THE FREEZING POINT ON THE 18TH OR 23RD. ON THE
OTHER SIDE OF THE SCALE, WARMEST TEMPERATURES OF THE MONTH WERE
EXPERIENCED ON THE 31ST WHERE MANY NON-HIGH TERRAIN LOCATIONS INLAND
FROM THE DOWNEAST COAST EXPERIENCED AFTERNOON HIGHS OF UPPER 80S TO
LOWER 90S WITH DAILY DEPARTURES UPWARDS TO 15 TO 20 DEGREES ABOVE
AVERAGE.

AVERAGE TOTAL PRECIPITATION FOR THE MONTH ACROSS THE ENTIRE REGION
RANGED FROM 80 TO 95 PERCENT WITH SIGNIFICANT DAILY AMOUNTS RECORDED
ACROSS ALL OR PARTS OF THE REGION ON THE 1ST, 12TH, 21ST AND 24TH-
25TH. THE LAST SNOW FLURRIES OF PREVIOUS COLD SEASON FELL ACROSS THE
NORTH DURING THE COLD BLUSTERY CONDITIONS EXPERIENCED ON THE 17TH.

TOTAL EVAPORATION AS MEASURED AT CARIBOU FOR MAY WAS APPROXIMATELY
5.40 INCHES. TOTAL RAINFALL A CARIBOU FOR THIS SAME PERIOD WAS 2.79
INCHES, OR ABOUT 52 PERCENT OF THE TOTAL EVAPORATION. AT BANGOR, THE
TOTAL JUNE RAINFALL WAS 2.95 INCHES, OR ONLY 55 PERCENT OF THE PROXY
CARIBOU EVAPORATION, MEANING THAT MUCH, IF NOT ALL OF OUR REGION
EXPERIENCED SIGNIFICANT DRYING FROM TYPICAL WET CONDITIONS FROM MUD
SEASON (SNOW AND FROST MELT) LAST MONTH.

THE CLIMATE PREDICTION CENTER`S OUTLOOK FOR THE MONTH OF JUNE 2023
IS CALLING FOR SLIGHTLY INCREASED ODDS OF ABOVE AVERAGE TEMPERATURE
AND EQUAL ODDS OF BELOW, NEAR, OR ABOVE AVERAGE PRECIPITATION FOR
OUR REGION. NORMAL JUNE TEMPS FOR THE 1991-2020 PERIOD FOR NORTHERN
(DOWNEAST) MAINE ARE LOWS OF AROUND 50 (LOWER 50S) AND HIGHS OF
LOWER 70S (MID TO UPPER 70S, EXCEPT AROUND 70 ALONG THE COAST).
NORMAL JUNE PRECIPITATION FOR THE ENTIRE ENTIRE REGION IS 3.50 TO
4.00 INCHES.
