...ACTIVE WEATHER PATTERN WITH COLD AND SNOW THEN RAIN AND
FLOODING...

THERE WAS A VERY ACTIVE WEATHER PATTERN THIS MONTH OF DECEMBER. IT
ALL STARTED WITH A BRIEF PERIOD OF WARM WEATHER THE FIRST WEEK OF
DECEMBER...WITH TEMPERATURES BRIEFLY TOUCHING THE LOW 60`S ON
DECEMBER 5TH. A COLD FRONT MOVED THROUGH THE REGION ON THE 6TH AND
SUCCESSIVE ROUNDS OF COLDER AIR PLUNGED SOUTHWARD FROM CANADA INTO
THE UNITED STATES INCLUDING ACROSS THE EASTERN GREAT LAKES REGION
THROUGH THE MIDDLE TO LATTER HALF OF DECEMBER. THIS IN TURN LED TO
OVERALL COLDER THAN AVERAGE TEMPERATURES. THIS COLD WAS ALSO
ACCOMPANIED BY SEVERAL SYNOPTIC AND LAKE EFFECT SNOW EVENTS.

THE COLDER AIR SPILLING ACROSS THE REGION FROM DECEMBER 10TH THROUGH
THE 11TH WOULD BE RESPONSIBLE FOR THE FIRST OF TWO NOTABLE LAKE
EFFECT SNOW EVENTS. THE FIRST EVENT DROPPED SEVERAL FEET OF SNOW
SOUTH OF BUFFALO AND BATAVIA. A SECOND EVENT ON THE 12TH AND 13TH
CAME ON THE HEELS OF OUR FIRST MAJOR LAKE EFFECT SNOW EVENT. HOWEVER
THIS TIME SNOW WAS NOT AS GREAT...AND THE BAND WAS A LITTLE FARTHER
TO THE NORTH WITH A HALF FOOT OF SNOW FALLING ACROSS METRO BUFFALO.
FOLLOWING THIS PERIOD OF COLD AND SNOWY WEATHER...A BRIEF WARM-UP
OCCURRED ALONG WITH COPIOUS AMOUNTS OF PRECIPITATION. THE
COMBINATION OF RAIN ON TOP OF THE RECENT SNOWFALL CAUSED AREA CREEKS
AND RIVERS TO SPILL OVER THEIR BANKS...WHILE MANY OF THEIR
TRIBUTARIES ALSO PRODUCED FIELD FLOODING...FLOODED BASEMENTS AND
CLOSED ROADWAYS. HOWEVER...THE WARM AND WET WEATHER WAS SHORT LIVED
AND ON THE 24TH OF DECEMBER A COLD FRONT WOULD BRING BUFFALO BACK
INTO A WINTER WONDER LAND. AS A RESULT FOR THE SECOND YEAR IN A ROW
BUFFALO SAW A WHITE CHRISTMAS.

DECEMBER`S AVERAGE TEMPERATURE WAS 28.0F DEGREES...WHICH WAS 2.1
DEGREES BELOW NORMAL AND WAS THE 2ND STRAIGHT MONTH OF BELOW AVERAGE
TEMPERATURES. ALTHOUGH...EVEN WITH ALL THE COLD NO RECORDS WERE SET
THIS MONTH. THE COLDEST DAYTIME HIGH THIS MONTH WAS ON DECEMBER 14TH WITH
A HIGH OF ONLY 17F DEGREES. ON THE FLIP SIDE OF THE COIN...A LOW OF
2F DEGREES WAS REACHED ON DECEMBER 25TH. THE WARMEST DAY OF THIS
MONTH OCCURRED ON DECEMBER 5TH WHEN THE MERCURY REACHED 61F AT
BUFFALO.

THERE WAS 4.93 INCHES OF PRECIPITATION THIS MONTH WHICH IS ABOUT AN
INCH MORE THAN NORMAL. THERE WERE TWO RECORD PRECIPITATION
EVENTS...ON 21ST AND 22ND. THESE NEW RECORDS (1.12 INCHES ON THE
21ST AND 1.38 INCHES ON THE 22ND) ACCOUNTED FOR ALMOST HALF OF THE
MONTHLY PRECIPITATION.

SNOW FOR THE MONTH OF DECEMBER CAME IN AT 28.5 INCHES...JUST A TAD
BIT(1.1 INCHES)ABOVE NORMAL. ROUGHLY HALF (14 DAYS) OF THE MONTH HAD
A SNOW COVER OF AN INCH OR GREATER.

WIND SPEED THIS MONTH AVERAGED 11.0 MPH...A FEW CLICKS (1.9
MPH)BELOW NORMAL. THE SUN DID NOT MAKE MUCH OF AN APPEARANCE THIS
MONTH...WHICH IS TYPICAL IN DECEMBER...WITH ONLY 21 PERCENT OF
POSSIBLE SUNSHINE WHICH IS 6 PERCENT BELOW NORMAL. THERE WERE 28
DAYS THIS MONTH MOSTLY TO COMPLETELY CLOUDY. LAKE ERIE REMAINED ICE
FREE WITH LAKE TEMPERATURES DROPPING FROM 41F DOWN TO 33F.

OVERALL THE MONTH OF DECEMBER WILL BE REMEMBER FOR ITS IMPRESSIVE
LAKE EFFECT SNOWS AND THE FLOODING OF AREA CREEKS AND RIVERS.
