...A WARM AND RAINY JANUARY FOR JUNEAU...

JANUARY 2016 WILL BE REMEMBERED FOR ABNORMALLY WARM TEMPERATURES AND FOR RECORD
LOW SNOWFALL.  THE MONTH BEGAN ON A WARM NOTE WITH HIGH TEMPERATURES ON THE 1ST
AND 2ND ABOVE 40 DEGREES.  THE 4TH THROUGH THE 9TH MARKED THE ONLY STRETCH OF
BELOW NORMAL TEMPERATURES FOR JANUARY WITH DAY TIME HIGHS BELOW THE FREEZING
MARK AND MORNING LOWS AS LOW AS 16 DEGREES.  FROM THE 10TH THROUGH THE END OF
THE MONTH...A SERIES OF WARM STORM SYSTEMS MOVED ACROSS SOUTHEAST ALASKA FROM
THE SOUTHWEST.  TEMPERATURES REMAINED WELL ABOVE NORMAL...PEAKING AS HIGH AS 47
DEGREES ON THE 27TH WHICH WAS A DAILY RECORD HIGH TEMPERATURE FOR THE JUNEAU
AIRPORT.  IN SPITE OF THE STRING OF COOLER THAN NORMAL DAYS NEAR THE BEGINING
OF THE MONTH...THE AVERAGE TEMPERATURE FOR THE JUNEAU AIRPORT WAS 6.6 DEGREES
ABOVE NORMAL FOR THE MONTH OF JANUARY.

JANUARY BEGAN WITH A RAINY STORM SYSTEM...A STARK CONTRAST FROM A COLD AND
SNOWY DECEMBER. THE MONTH THEN REMAINED DRIER THAN NORMAL FROM THE 4TH THROUGH
THE 9TH AS A RIDGE OF HIGH PRESSURE BROUGHT THE COOL TEMPERATURES AND CLEARING
SKIES TO THE JUNEAU AREA.  THE MONTH ENDED WITH A SERIES OF FRONTAL SYSTEMS
FROM THE CENTRAL PACIFIC BRINGING HIGH AMOUNTS OF MOISTURE INTO THE PANHANDLE.
THE PRECIPITATION PEAKED ON THE 27TH AND 28TH AS THE AIRPORT RECORDED TWO
CONSECUTIVE DAYS WITH GREATER THAN 0.75 INCHES OF RAIN.  OVERALL THE 6.53
INCHES OF PRECIPITATION RECORDED DURING THE MONTH OF JANUARY BOOSTED THE
AIRPORT TO 1.18 INCHES ABOVE NORMAL TO START THE YEAR.  BECAUSE OF THE WARM AIR
PULLED INTO THE PANHANDLE WITH THE CONSECUTIVE STORM SYSTEMS...THE JUNEAU
AIRPORT ONLY RECORDED A TRACE OF SNOWFALL DURING JANUARY.  THIS TIES THE RECORD
FOR THE LEAST AMOUNT OF SNOW EVER RECORDED FOR THE JUNEAU AIRPORT...A RECORD
THAT DATES BACK TO 1942.

ALONG WITH THE RAIN...THE JUNEAU AREA ALSO EXPERIENCED HIGH WINDS ON THE
MORNING OF THE 26TH AS A STRONG LOW PRESSURE SYSTEM TRACKED ACROSS THE AREA.
THE AIRPORT RECORDED A PEAK GUST OF 59 MPH DURING THIS STORM WHILE MANY AREAS
AROUND JUNEAU RECORDED WIND GUSTS OF 60 TO 70 MPH.

OVERALL THE MONTH OF JANUARY...WITH ITS WARM TEMPERATURES...RAIN AND WIND WAS
MORE REMENISCENT OF A WEATHER PATTERN DURING THE AUTUMN SEASON THAN THE HEART
OF WINTER.
