...RECORD WET SUMMER WEATHER FOR JUNEAU IN 2014...

THE YEAR 2014 BEGAN VERY MUCH WARMER AND WETTER THAN NORMAL WITH
SIGNIFICANTLY LESS THAN NORMAL SNOWFALL IN JUNEAU. AS IT TURNED OUT,
THESE TRENDS WOULD SET THE TONE FOR THE ENTIRE YEAR. 

NINE OF THE 12 MONTHS IN 2014 RECORDED MONTHLY AVERAGE TEMPERATURES THAT
WERE ABOVE NORMAL. UNFORTUNATELY FOR SNOW LOVERS, TWO OF THE THREE MONTHS
WITH THE GREATEST DEPARTURES ABOVE NORMAL WERE JANUARY AND THEN AGAIN IN
DECEMBER. THE JANUARY AVERAGE TEMPERATURE OF 36.3 DEGREES WAS A WHOPPING
8.3 DEGREES ABOVE NORMAL. ANOTHER NOTABLE WARMER-THAN-NORMAL MONTH WAS
MAY. WITH AN AVERAGE TEMPERATURE OF 52.2 DEGREES, MAY WAS 3.6 DEGREES
ABOVE NORMAL. IN MANY WAYS, SUMMER IN JUNEAU WAS THE MONTH OF MAY.
ALTHOUGH THE WARMEST DAY OF THE YEAR OCCURRED IN AUGUST WHEN THE
TEMPERATURE ROSE TO 77 DEGREES, MAY SPORTED SOME VERY FINE WARM WEATHER
WITH A WARMER AVERAGE HIGH TEMPERATURE THAN JUNE AND ONLY SLIGHTLY COOLER
THAN THE AVERAGE HIGHS FOR JULY AND AUGUST. THE DAILY HIGH OF 75 DEGREES
ON MAY 16TH TIED THE FIRST OF AUGUST FOR THE THIRD WARMEST DAY OF THE
YEAR. MAY IS ALREADY ONE OF THE DRIEST MONTHS OF THE YEAR AND, WITH A
PRECIPITATION DEFICIT OF 1.73 INCHES IN 2014, THE MONTH WAS ALL THE MORE
DRY AND SUMMER-LIKE. APART FROM MAY, WARMER THAN NORMAL CONDITIONS
GENERALLY OCCURRED DURING THE COLDER PORTIONS OF THE YEAR. JUNE TURNED
OUT TO BE 1.6 DEGREES BELOW NORMAL. JULY WAS NEAR NORMAL AND AUGUST WAS A
LITTLE LESS THAN ONE DEGREE ABOVE NORMAL. 

FOR AS ABNORMALLY WARM AS JANUARY WAS, FEBRUARY 2014 WAS EQUALLY EXTREME
AS A COLDER THAN NORMAL MONTH. ALTHOUGH NO RECORD COLD TEMPERATURES WERE
RECORDED, THE MONTHLY AVERAGE TEMPERATURE OF 23.9 DEGREES WAS 6.2 DEGREES
BELOW NORMAL. THE COLDEST NIGHT OF THE YEAR OCCURRED ON THE 12TH WHEN THE
MERCURY DIPPED DOWN TO ZERO, WHICH WAS 25 DEGREES BELOW THE NORMAL
OVERNIGHT VALUE FOR THAT TIME OF THE YEAR. DAILY HIGHS AND LOWS REMAINED
IN BELOW-NORMAL TERRITORY FOR ALL BUT 5 DAYS OF THE MONTH. A BRIEF BREAK
IN THE FRIGID CONDITIONS OCCURRED MID-MONTH BEGINNING ON THE 14TH.  IT
WAS DURING THIS TIME THAT JUNEAU RECEIVED MOST OF ITS FEBRUARY
PRECIPITATION AS WELL - NEARLY ALL OF IT AS SNOW AND NEARLY 2 FEET OVER
THE COURSE OF THOSE 5 DAYS. IN SPITE OF A PRECIPITATION DEFICIT OF LESS
THAN HALF THE NORMAL AMOUNT, FEBRUARY SNOWFALL OF 26.8 INCHES WAS 10
INCHES ABOVE NORMAL. THIS MID-MONTH SNOW WAS ONE OF ONLY TWO BRIGHT SPOTS
IN THE SNOW TOTALS FOR 2014. THE OTHER CAME IN THE LAST DAYS OF NOVEMBER.
AFTER VIRTUALLY NO SNOW AT ALL THROUGH NOVEMBER 28TH, THE SNOW SEASON IN
JUNEAU BEGAN WITH A MAJOR WINTER STORM THAT PRODUCED 9.8 INCHES. THE LATE
START TO THE SNOW SEASON WAS THE THIRD LATEST IN THE JUNEAU AREA SINCE
WORLD WAR II. UNFORTUNATELY, THERE WOULD BE VERY LITTLE ADDITIONAL SNOW
IN DECEMBER, WHICH WAS WARMER THAN NORMAL BY 3.5 DEGREES AND DRIER THAN
NORMAL BY 2.55 INCHES. THE RESULTING DECEMBER SNOWFALL OF 2.3 INCHES WAS
MORE THAN A FOOT BELOW NORMAL, AND THE ANNUAL SNOW TOTAL OF 51.1 INCHES
WAS ALMOST 3 FEET BELOW NORMAL. 

APART FROM SNOW TOTALS, ACCUMULATED PRECIPITATION TOTALS FOR THE YEAR
2014 STARTED OUT ABOVE NORMAL AND REMAINED AT OR ABOVE NORMAL ALL YEAR
LONG. THE RECORD FOR INDIVIDUAL MONTHS, HOWEVER, WAS NOT QUITE AS
DRAMATIC. IN FACT, 7 OF THE 12 MONTHS LAST YEAR ACTUALLY REPORTED BELOW
NORMAL MONTHLY PRECIPITATION VALUES. WHAT MADE THE DIFFERENCE WAS VERY
HEAVY PRECIPITATION IN JANUARY, AND THEN AGAIN DURING THE SUMMER MONTHS
OF JUNE, JULY, AND AUGUST. ACCUMULATED PRECIPITATION DURING THESE 3
MONTHS TOTALLED 24.27 INCHES AND REPRESENTED THE WETTEST SUMMER ON RECORD
FOR JUNEAU. OTHER NOTABLE WET SUMMERS INCLUDE 2006 IN THIRD PLACE WITH
21.38 INCHES, 2012 IN FIFTH PLACE WITH 19.65 INCHES, AND 2011 IN SIXTH
PLACE WITH 18.73 INCHES. AS A WHOLE, THE ANNUAL PRECIPITATION TOTAL OF
68.69 INCHES RANKS ONLY 12TH, BEHIND OTHER YEARS SUCH AS 2006 WITH 74.29
INCHES, 2013 WITH 73.74 INCHES, AND THE ALL-TIME WETTEST YEAR OF 1961
WITH 85.15 INCHES.
