...TYPICAL WINTER THIS NOVEMBER...

AFTER A MILD OCTOBER FOR BUFFALO...NOVEMBER BROUGHT WINTER
CHILLS...WINDS AND SNOW. SEVERAL COLD AIR MASSES MOVED ACROSS OUR
REGION THROUGHOUT THE MONTH...WHICH LED TO NOVEMBER FINISHING COOLER

SYNOPTICALLY DRIVEN SNOWS TO THE REGION. IN ADDITION...THERE WERE
TWO NOTABLE WIND EVENTS THIS MONTH AS WELL.

WERE 8 DAYS OF SNOWFALL...WHICH EXCEEDS THE NORMAL VALUE OF 5. THE
BUFFALO REGION FINISHED THE MONTH WITH SNOW COVERED LAWNS THAT
LASTED RIGHT THROUGH THE THANKSGIVING HOLIDAY WEEKEND.

STRONG WINDS MARKED THE START OF THE MONTH AS AN AREA OF LOW
PRESSURE MOVING THROUGH THE GREAT LAKES IN THE EARLY HOURS OF
NOVEMBER RAPIDLY DEEPENED...SWINGING A COLD FRONT ACROSS THE REGION
ON THE 1ST. THE CLASSIC TRACK OF A DEEPENING LOW TO WESTERN NEW
YORKS NORTH AND WEST BROUGHT STRONG WINDS TO THE REGION FELLING
TREES...AND BRINGING DOWN POWER LINES. THE HIGHEST WIND GUST FOR THE
MONTH OF 61 MPH WAS RECORDED AT THE AIRPORT ON NOV 1ST. MUCH
CHILLIER AIR BEHIND THE COLD FRONT DROPPED HIGH TEMPERATURES DOWN
INTO THE 30S BY SUNDAY THE 3RD. AN AMPLIFIED AND PROGRESSIVE PATTERN
FOLLOWED...WITH DAYS ABOVE AND BELOW NORMAL THROUGH THE FIRST HALF
OF THE MONTH. BEHIND ANOTHER COLD FRONT ON THE 11TH RAIN CHANGED TO
SNOW ON THAT MONDAY EVENING AND BROUGHT BUFFALO ITS FIRST MEASURABLE
SNOW OF THE SEASON. SEVERAL AREAS OF LOW PRESSURE PASSED BY THE
REGION IN THE 10TH TO 14TH TIME PERIOD MAINTAINING GUSTY WINDS
ACROSS THE AREA...WITH A WIND GUST TO 48 MPH ON THE 14TH...THE
GUSTIEST OF THE 5 DAYS. ON SUNDAY EVENING THE 17TH A SQUALL LINE
PASSED ACROSS WESTERN NEW YORK...THOUGH DAMAGE WAS MINIMAL WITH JUST
A FEW TREES REPORTED DOWN SOUTH OF BUFFALO. WINDS BECAME STRONGER
ONCE AGAIN BEHIND A COLD FRONT ON THE 18TH WITH A DEEPENING AREA OF
LOW PRESSURE MOVING TO THE NORTHWEST OF WESTERN NEW YORK. WIND GUSTS
AGAIN PRODUCED DAMAGE ACROSS THE REGION WITH DOWNED TREES AND POWER
LINES. BEHIND THIS STRONG COLD FRONT A PATTERN CHANGE OCCURRED WITH
A DEEP AND BROAD POOL OF COLD CANADIAN AIR PASSING OVER THE GREAT
LAKES REGION. THIS BROUGHT MAINLY BELOW NORMAL TEMPERATURES AND SOME
LAKE EFFECT SNOWS. CONDITIONS WERE NOT PRIMED FOR ANY BIG LAKE
EFFECT SNOWS...WITH MAINLY MANAGEABLE EVENTS OCCURRING...AND LARGELY

HOURS OF WEDNESDAY THE 27TH. THIS STORM BROUGHT SEVERAL INCHES OF
SNOW...WITH UPWARDS OF A HALF A FOOT FOUND ACROSS THE FAR EASTERN
SUBURBS OF BUFFALO...AND NEAR A FOOT ACROSS THE HILLS WELL SOUTH OF
BUFFALO. THE COLD FINISH TO THE MONTH ALSO BROUGHT THE FORMATION OF
ICE ON LOCAL BACKYARD PONDS AND STREAMS.
