...AN ACTIVE DECEMBER WITH SNOW AND COLD...

DECEMBER FEATURED PLENTY OF IMPACTFUL WINTER WEATHER EVENTS FOR
WESTERN NEW YORK WITH ACTIVE LAKE EFFECT SNOWS AND MULTIPLE SURGE`S
OF ARCTIC AIRMASSES. AFTER A SLOW START TO THE WINTER SEASON,
WINTERS FURY RAPIDLY INCREASED WITH MANY LAKE EFFECT SNOW
EVENTS...LEADING TO AN ABOVE NORMAL SNOWFALL MONTH. TWO ARCTIC
SURGES BROUGHT THE TEMPERATURE FOR THE MONTH TO BELOW NORMAL.

THE TEMPERATURE AVERAGED 25.4F THIS MONTH WHICH IS OVER FOUR AND A
HALF DEGREES BELOW NORMAL. IT WAS THE COLDEST DECEMBER SINCE THE
YEAR 2000. THE MONTH CAN BE BROKEN DOWN INTO FOUR DISTINCT PATTERNS.
THE FIRST 6 DAYS AVERAGED ABOVE NORMAL...INCLUDING TWO DAYS IN THE
LOWER 50S ON THE 4TH AND 5TH. THE FIRST ARCTIC SURGE OF THE MONTH
THEN LASTED THROUGH MID-MONTH, DROPPING OVERNIGHT TEMPERATURES BELOW
FREEZING EACH NIGHT. A BRIEF THAWING SPELL OCCURRED FROM THE 18TH
THROUGH THE 23RD...INCLUDING TWO DAYS IN THE LOWER 40S ON THE 18TH
AND 19TH. THEREAFTER ARCTIC AIR POURED OVER THE GREAT LAKES REGION,
PROGRESSIVELY LOWERING DAYTIME HIGHS FROM THE LOWER 30S TO THE
SINGLE DIGITS BY MONTH`S CLOSURE. THERE WERE 14 DAYS THAT REACHED
THE FREEZING MARK, 7 LESS THAN NORMAL, AND VIRTUALLY ALL DURING THE
FIRST HALF OF THE MONTH. THE HIGH TEMPERATURE OF 9F ON THE LAST DAY
OF THE MONTH WAS THE FIRST SINGLE DIGIT HIGH TEMPERATURE IN DECEMBER
SINCE 1989.

PRECIPITATION TOTALED 2.93 INCHES FOR THE MONTH, WHICH IS ABOUT AN
INCH BELOW NORMAL. MOST OF THE EVENTS WERE SNOW, WITH JUST ONE RAIN
EVENT ON THE 5TH-6TH, AND ONE FREEZING RAIN EVENT ON THE 23RD. SNOW
TOTALED ABOVE NORMAL FOR THE MONTH, WITH 33.7 INCHES OF SNOW
RECORDED. THIS IS THE GREATEST SNOW AMOUNT IN DECEMBER SINCE
DECEMBER OF 2008. THERE WERE 18 DAYS WITH MEASURABLE SNOW, AND 14
DAYS WITH AT LEAST AN INCH OF SNOW. THESE 14 DAYS TIES A DECEMBER
RECORD WITH THE DECEMBERS OF 2000 AND 1977. THOUGH THERE WERE NO
MAJOR SNOW EVENTS AT THE BUFFALO AIRPORT AS WIND FLOW TENDED TO BE
AN UNFAVORABLE NORTHWEST DIRECTION, THERE WERE 6 LAKE EFFECT SNOW
EVENTS OVER THE COURSE OF A BUSY MONTH. THIS BROUGHT GREATER THAN
NORMAL SNOW TOTALS ACROSS SKI COUNTRY AND THE WESTERN SOUTHERN TIER.
THE FREEZING RAIN EVENT ON THE 22ND-23RD BROUGHT A GLAZE TO A TENTH
OF AN INCH OF ICE TO ELEVATED SURFACES. PERSISTENT SNOWS FROM THE
23RD TO 25TH LED TO A WHITE CHRISTMAS WITH 7 INCHES OF SNOW ON THE
GROUND.

LAKE ERIE FELL TO 33F BY THE END OF THE MONTH, WITH ICE FORMING
ALONG THE SHORELINE AND IN THE BUFFALO HARBOR. THE STRONGEST WIND
GUST WAS 55 MPH ON THE 19TH.

IN ALL A WESTERN NEW YORK WINTER MONTH WITH COLD AND SNOW.
