...SUMMER 2016 NORTHERN AND EASTERN MAINE SEASONAL CLIMATE
NARRATIVE...

OVERALL...NORTHERN AND EASTERN MAINE FOR SUMMER (JUNE 1ST -AUGUST
31ST) 2016 EXPERIENCED ABOVE NORMAL TEMPERATURES...WITH DECIDELY
ABOVE NORMAL RAINFALL ACROSS THE NORTH AND SIGNIFICANTLY BELOW
AVERAGE RAINFALL OVER DOWNEAST PORTIONS OF THE REGION.

MOST LOCATIONS AVERAGED 1 TO 2 DEGREES F ABOVE NORMAL...WITH
CONSISTENCY OF WARMTH RATHER THAN EPISODES OF EXTREME HEAT BEING
THE RULE THIS SUMMER. AT CARIBOU...35 DAYS OF 80+ DEGREE HIGH
TEMPERATURES WERE RECORDED DURING THIS PERIOD...WITH 3 BEING
RECORDED IN MAY AND AN ADDITIONAL 3 DAYS CURRENTLY IN SEPTEMBER
GIVING A CURRENT WARM SEASON TOTAL OF 41...WELL ABOVE THE WARM
SEASON AVERAGE OF 26. THERE WERE NO 90 DEGREE DAYS THIS WARM SEASON
AT CARIBOU. BANGOR`S WARM SEASON TOTAL OF 59 DAYS OF 80+ DEGREES SO
FOR FOR THE ENTIRE WARM SEASON IS ALSO WELL ABOVE AVERAGE. THERE
WERE 2 90 DEGREE DAYS AT BANGOR THIS WARM SEASON... WHICH WAS 2
BELOW THE LONG TERM AVERAGE OF 4.

THE ONLY NOTABLE COOL SPELLS THIS SUMMER OCCURRED BETWEEN
JUNE 1ST AND 19TH AND JULY 7TH AND 10TH...BOTH OF WHICH ACTED TO
KEEP OVERALL SUMMER POSITIVE DEPARTURES FROM BEING SIGNIFICANTLY
WARMER.

IT WAS THE TALE OF TWO RAINFALL REGIMES FOR THE REGION THIS
SUMMER...WITH THE DIVIDING LINE ROUGHLY RUNNING THROUGH CENTRAL
PORTIONS OF THE REGION. ACROSS THE NORTH...RAINFALL WAS MUCH MORE
PLENTIFUL...WITH MORE FREQUENT SHOWER/THUNDERSTORM DAYS DUE TO MORE
FREQUENT COLD FRONTAL PASSAGES. FURTHER SOUTH...IT WAS MUCH DRIER
WITH DOWNEAST AREAS FORMING THE NORTHERN EDGE OF A SIGNIFICANT
DROUGHT REGIME THAT AFFECTED MUCH OF THE REST OF NEW ENGLAND.
OVERALL...RAINFALL DEPARTURES RANGE FROM AS LOW AS 65 PERCENT OF
NORMAL FOR PORTIONS OF THE LOWER PENOBSCOT VALLEY TO AS HIGH AS 135
PERCENT OF NORMAL FOR SOME LOCATIONS ACROSS FAR NORTHERN MAINE. THE
SEASONAL RAINFALL TOTAL OF 15.18 INCHES FOR CARIBOU WAS ACTUALLY THE
11TH WETTEST JUNE THROUGH AUGUST PERIOD OF RECORD SINCE RECORDS
BEGAN IN 1939. MEANWHILE...THE RELATIVELY MEAGER TOTAL OF 7.78
INCHES FOR THE SEASON AT BANGOR WAS THE 21ST LOWEST SINCE RECORDS
BEGAN THERE IN 1925.
