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

FEBRUARY 2017 FINISHED WITH ABOVE NORMAL TEMPERATURES, NEAR NORMAL
PRECIPITATION, AND VARIABLE SNOWFALL ACROSS THE REGION AS A WHOLE.

THIS MONTH WAS REALLY THE TALE OF TWO FEBRUARY`S WITHIN ONE MONTH;
THE COLD AND SNOWY FIRST HALF AND THE MUCH MILDER AND RAINY SECOND
HALF OF THE MONTH. OVERALL, MONTHLY AVERAGE TEMPERATURES FOR
LOCATIONS ACROSS THE REGION WERE FAIRLY TIGHTLY CLUSTERED BETWEEN
1.5 TO 3.0 DEGREES ABOVE NORMAL, WITH THE FIRST HALF OF THE MONTH
AVERAGING ABOUT 8 DEGREES BELOW NORMAL AND THE SECOND HALF 12 TO 13
DEGREES ABOVE NORMAL. THIS RESULTED IN WIDE DIFFERENCES BETWEEN
MONTHLY MINIMUM TEMPERATURES OF -10S AND -20S RECORDED ON THE 11TH
AND 12TH ACROSS THE NORTH AND MAXIMUM TEMPERATURES OF 50S TO EVEN
NEAR 60 DEGREES RECORDED OVER EASTERN AND ESPECIALLY DOWNEAST
PORTIONS OF THE REGION ON THE 23RD AND 24TH.

PRECIPITATION RANGED FROM AS LITTLE AS 75 PERCENT OF NORMAL AT A FEW
LOCATIONS ACROSS THE NORTH UPWARDS TO 130 PERCENT ALONG THE DOWNEAST
COAST. DURING THE COLD FIRST HALF OF THE MONTH, A MORE SOUTHERN
STORM TRACK FEATURED HEAVY SNOWSTORMS ON THE 8-10TH AND AGAIN ON THE
12TH AND 13TH OVER CENTRAL AND ESPECIALLY DOWNEAST PORTIONS OF THE
REGION, WHERE COMPARATIVELY LITTLE FELL IN PREVIOUS WINTER MONTHS
THIS SEASON. DURING THE SECOND HALF OF THE MONTH, A DRAMATIC CHANGE
IN THE STORM TRACK TO WELL NORTH AND WEST OF MAINE RESULTED IN
MOSTLY RAIN EVENTS EVEN AS FAR NORTH AS THE SAINT JOHN VALLEY.
SUBSEQUENTLY, ONLY 60 TO 75 PERCENT OF AVERAGE SNOWFALL OCCURRED
ACROSS THE FAR NORTH WHILE UPWARDS TO 250 TO 300 PERCENT OF AVERAGE
SNOWFALL OCCURRED OVER DOWNEAST AREAS. AT BANGOR, THE 37.4 INCH
TOTAL FOR THE MONTH WAS THE 5TH SNOWIEST FEBRUARY OF RECORD, BUT
STILL WELL SHORT OF THE ALL TIME RECORD SNOWIEST FEBRUARY OF 58.0
INCHES RECORDED IN FEBRUARY 1969.

SNOW DEPTH GENERALLY WAS ABOVE AVERAGE ACROSS THE ENTIRE REGION THIS
MONTH, REACHING A PEAK THROUGH MID MONTH THEN DECLINING IN THE LAST
THIRD WITH THAWING TEMPERATURES AND RAINFALL. IT`S INTERESTING TO
NOTE THAT EVEN THOUGH THE MAXIMUM SNOW DEPTH AT BOTH CARIBOU AND
BANGOR REACHED 31 INCHES AT MID MONTH, THERE WAS A MUCH GREATER
VARIATION OF SNOW PACK OVER DOWNEAST AREAS AS EVIDENT BY THE INITIAL
SNOW DEPTH MEASUREMENT OF A TRACE ON THE 1ST AND 1 INCH ON THE 28TH
AT BANGOR COMPARED TO THE TOTAL RANGE ONLY FROM 23 O 31 INCHES OF
SNOW DEPTH AT CARIBOU. THE SOLID AND MORE DENSE SNOW PACK ACROSS
CENTRAL AND ESPECIALLY NORTHERN PORTIONS OF THE REGION CONTINUED TO
PROVIDE EXCELLENT SKIING AND SNOW MOBILING CONDITIONS ESPECIALLY
DURING THE FIRST TWO THIRDS OF THE MONTH.

THE OFFICIAL CLIMATE PREDICTION CENTER OUTLOOK FOR MARCH 2017 ACROSS
NORTHERN AND EASTERN MAINE IS NOT SLATED IN ANY PARTICULAR DIRECTION
FOR TEMPERATURE OR TOTAL PRECIPITATION. TEMPERATURES TYPICALLY RANGE
FROM LOWS OF LOWER TEENS TO HIGHS LOWER 30S ACROSS THE FAR NORTH TO
LOWS OF AROUND 20 AND HIGH AROUND 40 OVER DOWNEAST AREAS. TOTAL
PRECIPITATION AVERAGES FROM 2.50 INCHES ACROSS THE FAR NORTH TO 3.00
INCHES OVER DOWNEAST AREAS. SNOWFALL AVERAGES FROM AROUND 10 INCHES
OVER DOWNEAST AREAS TO AROUND 20 INCHES ACROSS THE FAR NORTH.
