...TYPICAL NOVEMBER WINTER...

AFTER A MILD OCTOBER FOR ROCHESTER...NOVEMBER BROUGHT WINTER
CHILLS...WINDS AND SNOW. SEVERAL COLD AIR MASSES MOVED ACROSS OUR
REGION THROUGHOUT THE MONTH...WHICH LED TO NOVEMBER FINISHING COOLER
THAN NORMAL. THESE COLD AIRMASSES ALSO BROUGHT BOTH LAKE SNOWS AND
SYNOPTICALLY DRIVEN SNOWS TO THE REGION. IN ADDITION...THERE WERE
TWO NOTABLE WIND EVENTS THIS MONTH AS WELL.

THE AVERAGE TEMPERATURE FOR THE MONTH OF NOVEMBER WAS 37.5F
DEGREES...WHICH FINISHED 3.0 DEGREES BELOW NORMAL. WE HAVE NOT HAD A
MONTH FINISH THIS MUCH BELOW NORMAL SINCE DECEMBER OF 2010. THE
WARMEST DAY THIS MONTH WAS 67 DEGREES ON THE 6TH. THERE WERE TWO
RECORDS THIS MONTH...A NEW RECORD LOW WAS SET ON THE 13TH WITH THE
TEMPERATURE DIPPING DOWN TO 17F. A RECORD LOW MAXIMUM WAS TIED ON
THE 24TH...WITH THE 24F TYING THE MARK SET ALSO IN 1917. THE 7
NIGHTS OF TEMPERATURES DIPPING DOWN INTO THE TEENS WAS 5 MORE THAN
NOVEMBER`S NORMAL...AND MOST SINCE 1936 WHICH ALSO HAD 7 DAYS.

PRECIPITATION FOR NOVEMBER WAS 2.81 INCHES...WHICH IS JUST SHY OF
NORMAL. PRECIPITATION EVENTS WERE LIGHT WITH NO DAY RECEIVING MORE
THAN A HALF INCH OF EITHER RAINFALL...OR SNOW LIQUID EQUIVALENT. TWO
THIRDS OF THE MONTHS DAYS RECORDED MEASURABLE PRECIPITATION WHICH IS
5 MORE THAN NORMAL.

SNOWFALL FINISHED ABOVE NORMAL FOR THE MONTH. THERE WAS 13.5 INCHES
OF SNOW RECORDED FOR NOVEMBER...WHICH IS JUST OVER 7 INCHES
MORE THAN NORMAL. THERE WERE 7 CONSECUTIVE DAYS OF MEASURABLE SNOW
FROM THE 23RD TO THE 29TH. THIS IS ONE SHY OF THE NOVEMBER RECORD OF
8 SET BACK IN 1873. THE FIRST MEASURABLE SNOW OF THE WINTER SEASON
OCCURRED ON THE 8TH WITH 0.2 INCHES OF SNOW RECORDED. IN ALL THERE
WERE 10 DAYS OF SNOWFALL...WHICH EXCEEDS THE NORMAL VALUE OF 6. THE
ROCHESTER 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. 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 ROCHESTER ITS FIRST INCH OF SNOW...WITH 1.2 INCHES
RECORDED. SEVERAL AREAS OF LOW PRESSURE PASSED BY THE REGION IN THE
10TH TO 14TH TIME PERIOD MAINTAINING A BREEZE ACROSS THE
AREA...WITH A WIND GUST TO 44 MPH ON THE 10TH...THE GUSTIEST OF THE
5 DAYS. ON SUNDAY EVENING THE 17TH A SQUALL LINE PASSED ACROSS
WESTERN NEW YORK...THOUGH DAMAGE WAS MINIMAL. 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. A 63 MPH WIND GUST WAS RECORDED AT THE ROCHESTER AIRPORT.
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 ALONG
THE SOUTHERN LAKE ONTARIO SHORELINE AND TO AREAS EAST OF ROCHESTER. A
SYNOPTIC LOW BROUGHT WIDESPREAD SNOW LATE ON THE 26TH AND THROUGH
THE MORNING HOURS OF WEDNESDAY THE 27TH. THIS STORM BROUGHT A HALF A
FOOT OF SNOW TO THE METRO ROCHESTER AREA. THE COLD FINISH TO THE
MONTH ALSO BROUGHT THE FORMATION OF ICE ON LOCAL BACKYARD PONDS AND
STREAMS.

THE AVERAGE WIND SPEED THIS MONTH WAS 10.5 MPH...JUST A FEW TICKS
BELOW NORMAL. THE TWO SIGNIFICANT WIND EVENTS BROUGHT A GUST TO 58
MPH ON THE 1ST AND A GUST TO 63 MPH ON THE 18TH. LAKE ONTARIO DROPPED
FROM 54 DEGREES DOWN TO 41 DEGREES BY MONTHS END.

IN ALL NOVEMBER WAS A CHILLY MONTH...WITH SNOWY CONDITIONS TOWARDS
THE END.
