...AUGUST 2019 NORTHERN AND EASTERN MAINE CLIMATE NARRATIVE...

AUGUST 2019 FINISHED WITH SLIGHTLY ABOVE AVERAGE TEMPERATURES
FOR THE REGION AS A WHOLE AND RAINFALL THAT RANGED FROM BELOW NORMAL
ACROSS THE NORTH TO MUCH ABOVE AVERAGE ACROSS DOWNEAST AREAS.

AVERAGE TEMPERATURES RANGED FROM -0.3 DEGREES BELOW AVERAGE AT
HOULTON TO +1.5 DEGREES AT CARIBOU WITH OTHER CLIMATE LOCATIONS
MOSTLY BETWEEN AVERAGE AND +1.0. UNUSUAL FOR AUGUST WERE NO 90 DEGREE
HIGH TEMPS NOT EVEN AT MILLINOCKET OR BANGOR. MOST LOCATIONS
EXPERIENCED MONTHLY HIGH TEMPS IN THE MID 80S AND A NEAR NORMAL
COMPLIMENT OF 80+ DEGREE HIGH TEMPS.

RAINFALL, HOWEVER, VARIED WIDELY FROM AS LITTLE AS 65 PERCENT OF
AVERAGE ACROSS THE NORTH TO AROUND 100 PERCENT OF AVERAGE OVER
CENTRAL AREAS RAMPING QUICKLY UPWARDS TO 250 PERCENT OF NORMAL OVER
SOME DOWNEAST LOCATIONS. AT BANGOR, THE MONTHLY TOTAL OF 7.54 INCHES
FINISHED 2ND TO THE 8.32 INCH TOTAL RECORDED IN 2011. THE LARGEST
DAILY CONTRIBUTION AT BANGOR OCCURRED ON THE 8TH WHEN A RECORD 3.11
INCHES OF RAINFALL FELL. THIS WAS THE 2ND GREATEST AUGUST DAILY
TOTAL AT BANGOR, WITH 3.67 INCHES ON AUGUST 19TH 1965 REMAINING THE
WETTEST AUGUST DAY OF RECORD AT BANGOR.

MONTHLY EVAPORATION AT CARIBOU WAS 4.67 INCHES, A LITTLE MORE THAN 2
INCHES HIGHER THAN NORTHERN MAINE MONTHLY RAINFALL TOTALS. THIS
RESULTED IN DRY SOIL CONDITIONS, SEMI BROWN GRASS LAWNS, AND LOW
RIVER AND STREAM LEVELS FOR NORTHERN AND SOMEWHAT FOR CENTRAL
PORTIONS OF THE REGION. THIS WAS NOT THE CASE, THOUGH, FOR DOWNEAST
AREAS WHERE RAINFALL EASILY EXCEEDED THIS PROXY EVAPORATION VALUE.
