THE REGION AS A WHOLE AVERAGED 6.5 TO 8.0 DEGREES ABOVE AVERAGE WITH
MILD OVERNIGHT LOWS BEING THE LARGEST CONTRIBUTOR TO THE DEPARTURES.
BANGOR...CARIBOU AND HOULTON HAD THEIR 4TH...5TH AND 8TH WARMEST

VALLEY. AT BANGOR...THE MONTHLY TOTAL OF 6.0 INCHES FINISHED AS THE
5TH LEAST SNOWIEST JANUARY. THIS DISTRIBUTION OF SNOWFALL IS TYPICAL

THE 7TH HIGHEST WHILE AT BANGOR...THE AVERAGE OF 3.1 INCHES WAS THE
15TH LOWEST.

THE CLIMATE PREDICTION CENTER OUTLOOK FOR FEBRUARY INDICATES THAT
THERE ARE NO STRONG CLIMATE SIGNALS THAT WOULD POINT TOWARD AN
UNUSUALLY COLD OR MILD FEBRUARY. THERE ARE ALSO NO STRONG CLIMATE
SIGNALS THAT WOULD FAVOR AN UNUSUALLY WET (SNOWY) OR DRY MONTH. ON
AVERAGE...SNOWFALL DURING THE MONTH OF FEBRUARY RANGES FROM AROUND 2
FEET ACROSS THE CROWN OF MAINE, WITH HIGHER AMOUNTS ACROSS THE
HIGHER TERRAIN, AND AROUND 1 FOOT ALONG THE DOWNEAST COAST.

AVERAGE TEMPERATURES BEGIN A SLOW UPWARD SWING DURING THE MONTH OF
FEBRUARY.  THE AVERAGE HIGHS RISE FROM AROUND 20 DEGREES AT THE
START OF THE MONTH ACROSS THE SAINT JOHN VALLEY TO UPPER 20S IN THE
GREATER BANGOR REGION.  BY THE END OF THE MONTH...AVERAGE HIGHS RISE
TO THE MID TO UPPER 20S IN THE SAINT JOHN VALLEY AND TO THE MID 30S
AT BANGOR.  AVERAGE LOWS DURING THE MONTH RISE FROM NEAR ZERO AT THE
START OF THE MONTH IN THE FAR NORTH TO 5 TO 10 ABOVE BY THE END OF
THE MONTH.  AT BANGOR...AVERAGE LOWS RISE FROM 7 DEGREES ON THE 1ST
TO 14 DEGREES BY THE END OF THE MONTH.  THERE IS A GAIN OF JUST OVER
AN HOUR OF AVAILABLE DAYLIGHT DURING THE MONTH OF FEBRUARY.

THE ALL-TIME LOWEST TEMPERATURE EVER OBSERVED AT CARIBOU OCCURRED ON
FEBRUARY 1, 1955...WITH A LOW OF 41 BELOW.  AT BANGOR...THE ALL-TIME
RECORD LOW OF 32 BELOW WAS OBSERVED ON FEBRUARY 10, 1948.
