...NORTHERN AND EASTERN MAINE MONTHLY AREA CLIMATE NARRATIVE...

JULY 2015 FEATURED BELOW NORMAL TEMPERATURES. TEMPERATURES RANGED
FROM 1 TO 2 DEGREES BELOW NORMAL. PRECIPITATION WAS HIGHLY VARIABLE
AND RANGED FROM WELL BELOW NORMAL ACROSS MOST OF DOWNEAST MAINE TO
ABOVE NORMAL ACROSS NORTHWEST MAINE.

AT CARIBOU...THE AVERAGE TEMPERATURE OF 64.5 DEGREES WAS 1.1 DEGREES
BELOW NORMAL.  IT WAS THE COOLEST JULY SINCE 2009 AND RANKED AS THE
25TH COOLEST JULY ON RECORD.  AT BANGOR...THE AVERAGE TEMPERATURE OF
67.0 DEGREES WAS 1.5 DEGREES BELOW NORMAL.  IT WAS ALSO THE COOLEST
JULY SINCE 2009 AND RANKED AS THE 19TH COOLEST JULY ON RECORD. SIX
OF THE FIRST 7 MONTHS OF 2015 HAVE FEATURED BELOW NORMAL
TEMPERATURES.  YEAR TO DATE IT HAS BEEN THE COLDEST YEAR ON RECORD
AT BANGOR AND THE 6TH COLDEST AT CARIBOU.

TEMPERATURES THIS PAST JULY AT CARIBOU RANGED FROM A LOW OF 45
DEGREES ON THE 17TH TO A HIGH OF 85 DEGREES ON THE 30TH.  AT
BANGOR...TEMPERATURE RANGED FROM A LOW OF 47 DEGREES ON THE 17TH TO
87 DEGREES ON THE 12TH AND 29TH.  THERE WAS AN UNUSUALLY COOL AIR
MASS TOWARD THE MIDDLE OF THE MONTH THAT SENT TEMPERATURES DOWN INTO
THE 30S IN MANY OF THE NORMALLY COLDER VALLEYS ACROSS NORTHERN MAINE
ON THE 16TH AND 17TH.  HOULTON HAD BACK TO BACK LOWS IN THE 30S.

PRECIPITATION WAS MORE VARIABLE IN NATURE...AND RANGED FROM ONLY 25
TO 50 PERCENT ACROSS MUCH OF DOWNEAST MAINE TO AS MUCH AS 200
PERCENT OF NORMAL ACROSS PARTS OF NORTHWEST MAINE.

THERE WAS A LACK OF SEVERE WEATHER THIS PAST JULY WITH NO SEVERE
THUNDERSTORM WARNINGS ISSUED UNTIL THE AFTERNOON OF THE 27TH WHEN
THUNDERSTORMS KNOCKED DOWN TREES IN ALLAGASH AND SAINT FRANCIS.  ON
THE 28TH PING PONG SIZED HAIL WAS OBSERVED IN ALTON IN PENOBSCOT
COUNTY.

AT BANGOR...ONLY 1.16 INCHES OF RAIN WAS OBSERVED...WHICH WAS 2.30
INCHES BELOW NORMAL.  IT RANKED AS THE 8TH DRIEST JULY ON RECORD.
AT CARIBOU...3.19 INCHES OF RAIN WAS OBSERVED...WHICH WAS 89
HUNDREDTHS (0.89") BELOW NORMAL.

THE OUTLOOK FROM THE CLIMATE PREDICTION CENTER FOR THE MONTH OF
AUGUST FOR OUR REGION CALLS FOR AN INCREASED LIKELIHOOD OF ABOVE
NORMAL TEMPERATURES.  THERE ARE NO STRONG CLIMATE SIGNALS THAT WOULD
POINT TOWARD AN UNUSUALLY WET OR DRY MONTH.

THE AVERAGE TEMPERATURES BEGIN TO SLOWLY DROP DURING THE MONTH OF
AUGUST.  AT CARIBOU (BANGOR)...THE AVERAGE HIGH FALLS FROM 76 (80)
TO 71 (75).  THE AVERAGE LOW TEMPERATURES AT CARIBOU (BANGOR) FALL
FROM 55 (58) TO 50 (53). ONE AND ONE HALF HOURS OF DAYLIGHT IS LOST
DURING THE MONTH OF AUGUST.
