Summer 2014 Climate Summary for northern and eastern Maine

...Northern and eastern Maine narrative for summer (June through August) 2014...

Overall, the summer of 2014 was warmer than normal and temperatures
averaged 1 to 2.5 degrees above normal. The most significant
departures from average were across far northeast Maine.
Precipitation as is usually the case was much more variable
geographically across the region, but generally it was a wetter
summer across Down East maine where precipitation was up to 150
percent of normal. Areas across northern Maine and in particular in
the Saint John Valley precipitation was around 75 percent of normal.

There was a stretch of very warm weather at the tail end of June
into the first few days of July preceding Hurricane Arthur that
produced 7 consecutive days with highs in the 80s across most of the
region. The high temperature this past summer at Caribou was 91F on
July 2nd. The low temperature on the 2nd of 71F tied for the
all-time warmest low temperature on record at Caribou.  The high
temperature this past summer at Bangor was 89F.  It was the first
summer since 1986 when the high temperature at Bangor failed to
reach 90 degrees. The week long stretch of warm weather was followed
by an unusually cool day on the 5th when temperatures in parts of
northern Maine fell into the 40s during the afternoon, and snow
levels fell to around 1500 feet.

The most significant weather event of the summer was Hurricane
Arthur which affected the region on July 4th weekend.  The hurricane
transitioned into a strong extra-tropical storm as it tracked up the
Bay of Fundy.  The greatest rainfall totals of 5 to 7 inches were
observed in southern and eastern Washington County. Wind gusts in
Excess of 50 mph were common across eastern Maine. Washington County
was hard hit with many trees knocked down and power outages.

Severe weather was below normal with only 18 severe weather warnings
issued between June 1st and August 31st, which is well below normal.
The first thunderstorm of the season was not observed at the
National weather service office in Caribou until July 23rd, which was several
weeks later than average.
