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. && REYNOLDS $$
