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

JUNE 2017 FINISHED WITH MOSTLY SLIGHTLY ABOVE AVERAGE TEMPERATURES
AND ABOVE AVERAGE PRECIPITATION FOR NORTHERN AND EASTERN MAINE.

AVERAGE TEMPERATURES ACROSS THE REGION RANGED FROM 0.5 DEGREES BELOW
AVERAGE TO 1.5 DEGREES ABOVE AVERAGE. THE MONTH BEGAN ON THE COOL
SIDE THE FIRST WEEK BUT THEN WARMED SIGNIFICANTLY DURING THE SECOND
WEEK WITH A FEW DAYS WITH HIGH TEMPS IN THE 80S AND EVEN A 90+
DEGREE HIGH TEMP FOR SOME LOCATIONS ON THE 11TH...WHICH INCLUDED
RECORD HIGH TEMPS FOR CARIBOU...HOULTON...MILLINOCKET AND BANGOR.
AFTER ANOTHER BRIEF COOL DOWN IN THE BEGINNING OF WEEK THREE...
TEMPERATURES SETTLED TO NEAR NORMAL FOR THE REMAINDER OF THE MONTH.

THE TEMPERATURE DROPPED BELOW FREEZING ON THE MORNING OF THE 27TH AT
ESTCOURT STATION IN FAR NORTHWEST MAINE WITH A LOW OF 31F.  THERE WERE
SEVERAL VALLEY LOCATIONS IN NORTHERN MAINE WITH LOWS IN THE MID TO UPPER
30S THAT MORNING.

TYPICAL OF MANY SUMMER MONTHS...MONTHLY TOTAL RAINFALL VARIED FROM
PLACE TO PLACE WITH LITTLE IN THE WAY OF ANY COHERENT PATTERN DUE TO
THE RANDOMNESS OF DAY TO DAY SHOWER AND THUNDERSTORM LOCATION
OCCURRENCE. HOULTON WITH ONLY A 2.92 INCH TOTAL RECEIVED ABOUT 80
PERCENT OF AVERAGE JUNE RAINFALL WHILE FRENCHVILLE AND MILLINOCKET
WITH 5.84 AND 6.16 INCHES RECEIVED ABOUT 140 TO 150 PERCENT OF
AVERAGE JUNE RAINFALL. MANY OF THE REMAINDER CLIMATE SITES SUCH AS
CARIBOU AND BANGOR RECEIVED ABOUT A 110 TO 120 PERCENT OF AVERAGE
JUNE RAINFALL. THE RAINFALL CHARACTER OF THE MONTH BEGAN QUITE DRY
OVER THE FIRST TWO WEEKS, THEN BECAME MUCH RAINIER THROUGH THE
REMAINDER OF THE MONTH.

THE OFFICIAL OUTLOOK FOR JULY 2017 FROM THE CLIMATE PREDICTION
CENTER INDICATES AN INCREASED LIKELIHOOD OF ABOVE AVERAGE
TEMPERATURES. THERE ARE NO STRONG CLIMATE SIGNALS THAT WOULD TILT
THE ODDS TOWARD AN UNUSUALLY WET OR DRY JULY.

THE AVERAGE HIGH TEMPERATURE AT CARIBOU PEAKS AT 76 DEGREES FROM THE
11TH THROUGH THE END OF THE MONTH.  THE AVERAGE LOW PEAKS OUT AT 55
DEGREES FROM THE 10TH THROUGH THE END OF THE MONTH.  JULY IS ON

RAIN.  AT BANGOR, THE AVERAGE HIGH TEMPERATURE PEAKS OUT AT 80
DEGREES FROM THE 13TH THROUGH THE END OF THE MONTH.  THE AVERAGE LOW

JULY.  CLOSE TO AN HOUR OF AVAILABLE DAYLIGHT IS LOST DURING THE
MONTH OF JULY. THE SEVERE WEATHER SEASON PEAKS DURING JULY WITH MORE
REPORTS OF DAMAGING WIND AND LARGE HAIL DURING THE MONTH OF JULY
THAN DURING ANY OTHER MONTH OF THE YEAR.
