...WARMEST OR NEAR WARMEST YEAR ON RECORD FOR SOUTHEAST ALASKA...

AS WAS THE CASE FOR OTHER PARTS OF THE STATE OF ALASKA, THE YEAR
2016 WAS SIGNIFICANTLY WARMER THAN NORMAL AND WAS THE WARMEST ON
RECORD FOR SOME LOCATIONS. THE ANNUAL AVERAGE TEMPERATURE IN JUNEAU
WAS 51.1 DEGREES, A MERE 0.3 DEGREES BELOW THE RECORD YEAR OF 1941.
AT 50.8 DEGREES, YAKUTAT RECORDED ITS WARMEST YEAR EVER. SITKA SAW
ITS SECOND WARMEST YEAR WITH AN AVERAGE TEMPERATURE OF 53.3 DEGREES.
LIKEWISE FOR ANNETTE ISLAND AT 55.1 DEGREES ANNUAL AVERAGE
TEMPERATURE. A REVIEW OF DAILY TEMPERATURES FOR ALL FOUR CLIMATE
SITES REVEALS SEVERAL RECORD HIGHS SET THROUGHOUT THE YEAR WITH NO
RECORD LOW TEMPERATURES NOTED. IN FACT, DAILY LOWS SELDOM DROPPED
BELOW CLIMATOLOGICAL LOWS. EXCEPTIONS INCLUDED A BRIEF TIME IN EARLY
JANUARY, A LARGE PORTION OF OCTOBER FOR NORTHERN LOCATIONS, AND THE
FIRST HALF OF DECEMBER. UNUSUALLY WARM WEATHER PUNCTUATED THE RECORD
MUCH OF MARCH, DURING THE FIRST HALF OF MAY, AND AGAIN AT THE END OF
AUGUST GOING INTO SEPTEMBER.

ACCUMULATED PRECIPITATION TRENDED FROM SLIGHTLY ABOVE NORMAL FOR
JUNEAU TO BELOW NORMAL BY MORE THAN 35 INCHES FOR YAKUTAT. GENERAL
PRECIPITATION TRENDS FOR THE YEAR WERE FOR NEAR NORMAL TO ABOVE
NORMAL PRECIPITATION UP TO OCTOBER. AT THAT POINT, PRECIPITATION
DRIED UP SIGNIFICANTLY ACROSS SOUTHEAST ALASKA AND SOME OF THE
FINEST AUTUMN WEATHER THAT MANY CAN REMEMBER ENSUED.

SNOWFALL FOR THE YEAR WAS WELL BELOW NORMAL ACROSS THE PANHANDLE.
FOR THE THREE STATIONS THAT STILL REPORT SNOWFALL, LITTLE TO NO SNOW
FELL IN THE FIRST PART OF 2016. MEASURABLE SNOW FEW FOR THE FIRST
TIME THIS SNOW SEASON EARLY IN JUNEAU, WITH 5.1 INCHES RECORDED AT
THE AIRPORT ON THE 16TH OF THE MONTH, MAKING THIS PAST OCTOBER THE
THIRD SNOWIEST ON RECORD FOR THE CAPITAL CITY. APART FROM THIS EARLY
SNOW, THE YEAR 2016 RECORDED THE LOWEST OR NEARLY LOWEST ANNUAL
SNOWFALL FOR ALL THREE SNOW CLIMATE SITES.
