July 2022 Climate Summary for Northern and Eastern Maine

...JULY 2022 NORTHERN AND EASTERN MAINE CLIMATE NARRATIVE...

JULY 2022 FINISHED A LITTLE WARMER THAN AVERAGE. IT WAS WETTER THAN

NORMAL ACROSS MUCH OF THE REGION. THE EXCEPTIONS WERE IN BANGOR AND

AREAS SOUTH TO THE COAST, NORTHERN SOMERSET COUNTY, WESTERN

PISCATAQUIS COUNTY, AND PARTS OF FAR EASTERN WASHINGTON COUNTY WHERE

PRECIPITATION WAS BELOW AVERAGE.

TEMPERATURES GENERALLY RANGED FROM 1 TO 2 DEGREES ABOVE AVERAGE

ACROSS THE REGION. THERE WERE NO 90 DEGREE DAYS IN CARIBOU OR

HOULTON. THERE WERE TWO 90 DEGREE DAYS IN MILLINOCKET, AND THREE IN

BANGOR WHERE THERE WERE CONSECUTIVE 90 DEGREE DAYS ON JULY 22-24.

RAINFALL WAS ABOVE AVERAGE AT HOULTON AND MILLINOCKET, AND JUST

SLIGHTLY BELOW THE 30-YEAR AVERAGE IN CARIBOU. RAINFALL WAS BELOW

AVERAGE IN BANGOR. RAINFALL RANGED FROM 90 TO 150 PERCENT OF NORMAL

ACROSS MUCH OF THE AREA FROM CENTRAL PENOBSCOT COUNTY NORTH, EXCEPT

ACROSS NORTHERN SOMERSET AND WESTERN PISCATAQUIS COUNTY WHERE

RAINFALL WAS 25 TO 70 PERCENT OF NORMAL. IN SOUTHERN PENOBSCOT AND

COASTAL AND CENTRAL SECTIONS OF HANCOCK COUNTY AS WELL AS SOUTHEAST

WASHINGTON COUNTY RAINFALL RANGED FROM 70 TO 90 PERCENT OF NORMAL.

THE LARGEST RAINFALL DEPARTURE WAS OBSERVED IN HOULTON WHERE 6.02

INCHES OF RAIN WAS OBSERVED WHICH WAS 2.39 INCHES ABOVE NORMAL, AND

RANKED AS THE 8TH WETTEST JULY ON RECORD.

TOTAL EVAPORATION AT CARIBOU FOR THE MONTH WAS 5.02 INCHES, BUT THIS

LIKELY WAS AN UNDERESTIMATE FOR DOWNEAST AREAS WHICH HAD WARMER

TEMPERATURES AND DRIER SOILS. IN ANY EVENT, THERE WERE RAINFALL

SURPLUSES ACROSS MUCH OF THE NORTH AND DEFICITS ACROSS INTERIOR

DOWNEAST AREAS.

THE CLIMATE PREDICTION CENTER`S FORECAST FOR THE MONTH OF AUGUST FOR

OUR REGION IS CALLING FOR SLIGHTLY INCREASED ODDS OF ABOVE NORMAL

TEMPERATURES AND INCREASED ODDS OF BELOW NORMAL RAINFALL. SEVEN OF

THE TOP 10 WARMEST AUGUSTS HAVE OCCURRED IN CARIBOU SINCE 2010.

AVERAGE TEMPERATURES RANGE FROM LOWS AND HIGHS OF MID 50S AND MID TO

UPPER 70S OVER FAR NORTHERN AREAS TO UPPER 50S AND AROUND 80 DEGREES

FOR INTERIOR DOWNEAST AREAS. THE AVERAGE TEMPERATURES BEGIN TO

SLOWLY FALL DURING THE MONTH, MOST SO DURING THE SECOND HALF OF THE

MONTH. AVERAGE AUGUST RAINFALL RANGES FROM NEAR 3 INCHES OVER

DOWNEAST AREAS UPWARDS TO 3.6 INCHES ACROSS THE EXTREME NORTH.

AUGUST RANKS AS THE 3RD MOST ACTIVE MONTH AS FAR AS SEVERE

THUNDERSTORMS ACROSS THE REGION, BUT THE FREQUENCY OF SEVERE WEATHER

BEGINS TO DROP DURING THE 2ND HALF OF THE MONTH. NEARLY 1.5 HOURS OF

DAYLIGHT IS LOST DURING THE MONTH OF AUGUST.
