...SNOWY START TO WINTER...

AFTER A FINE FALL...THE MONTH OF NOVEMBER QUICKLY TURNED TO WINTER`S
CHILL...WIND AND SNOW. SEVERAL COLD AIRMASSES SURGED SOUTHWARD
ACROSS THE GREAT LAKES DURING THE MONTH WITH THE COLDEST AIRMASS
TRIGGERING A HISTORIC LAKE EFFECT SNOW EVENT. THIS HISTORIC SNOW
EVENT WAS ACTUALLY MADE UP OF TWO SEPARATE LAKE EFFECT SNOW STORMS
THAT COMBINED TO DROP MORE THAN 7 FEET OF SNOW JUST MERE MILES SOUTH
OF THE AIRPORT IN BUFFALO NEW YORK.

THE AVERAGE TEMPERATURE FOR THE MONTH OF NOVEMBER WAS 37.8F
DEGREES...WHICH IS ABOUT 3 DEGREES BELOW NORMAL. THE WARMEST DAY
THIS MONTH WAS 68 DEGREES ON THE 11TH. THERE WERE NO TEMPERATURE
RECORDS SET THIS MONTH. THERE WERE BRIEF WARM STRETCHES THIS MONTH
WITH EACH STRETCH REACHING INTO THE 60S. HOWEVER THESE WARM SPELLS
ONLY LASTED ABOUT THREE DAYS EACH AND ENDED WITH THE NEXT SURGE OF
ARCTIC AIR.

TOTAL PRECIPITATION FOR NOVEMBER WAS 2.58 INCHES...WHICH IS ABOUT AN
INCH AND A HALF BELOW NORMAL. THERE WAS NO SIGNIFICANT RAIN THIS
MONTH...AS ALL RAINFALL EVENTS WERE A QUARTER OF AN INCH OR LESS.
THE GREATEST DAILY PRECIPITATION AMOUNT WAS 0.51 INCHES...WHICH FELL
AS SNOW DURING A LAKE EFFECT EVENT.

MONTHLY SNOWFALL AT THE AIRPORT WAS 20.5 INCHES...WHICH MAKES
THIS THE 10TH SNOWIEST NOVEMBER ON RECORD. THIS MONTHLY AMOUNT MAY
BE A BIT DECEIVING ON A REGIONAL SCALE...AS JUST A FEW MILES AWAY 5
TO 7 FEET OF SNOW FELL ACROSS THE BUFFALO SOUTHTOWNS. THERE WAS ONE
NEW DAILY RECORD SNOWFALL SET...AS THE 7.6 INCHES THAT FELL ON THE
19TH BROKE THE OLD RECORD OF 5.8 INCHES SET BACK IN 2000. BETWEEN
THE 17TH AND 20TH WE HAD A 4-DAY STRETCH WHERE EACH DAY ACCUMULATED
AT LEAST ONE INCH OF SNOW...WHICH HAPPENED FOR JUST THE 5TH TIME IN
THE MONTH OF NOVEMBER.

THE HEMISPHERIC PATTERN THIS MONTH FEATURED A STRONG RIDGE OF HIGH
PRESSURE OVER ALASKA AND THE WESTERN UNITED STATES...WITH A TROUGH
OF LOW PRESSURE OVER THE EASTERN HALF OF THE UNITED STATES. THIS
AMPLIFIED PATTERN LED TO LATE FALLS WARMTH BEING REPLACED BY
INCREASING OUTBREAKS OF ARCTIC AIR FROM THE NORTH. THROUGH THE FIRST
TWO WEEKS OF NOVEMBER WE HAD TWO BRIEF WARM-UPS...THE 3RD-6TH AND
THE 10TH-12TH. AFTER THE FIRST WARM-UP A COLD FRONT BROUGHT OUR
FIRST SNOWFLAKES OF THE WINTER SEASON ON THE 7TH. AFTER THE SECOND
WARM-UP A COLD FRONT BROUGHT OUR FIRST MEASURABLE SNOWFALL ON THE
13TH OF THE MONTH.

TEMPERATURES REMAINED BELOW NORMAL THROUGH THE THIRD WEEKEND OF THE
MONTH...WHICH SET THE STAGE FOR AN EPIC LAKE EFFECT SNOW EVENT
DOWNWIND OF LAKE ERIE. A DEEP UPPER LEVEL LOW WAS SITUATED OVER THE
WESTERN GREAT LAKES WITH COLD SOUTHWEST WINDS RUSHING OVER THE WARM
LAKE WATERS OF LAKE ERIE. A BAND OF VERY HEAVY LAKE EFFECT SNOW
BROUGHT UPWARDS OF 4 FEET TO LOCALIZED AREAS FROM THE EVENING OF THE
17TH...THROUGH THE FIRST PART OF THE 19TH. THIS BAND REMAINED NEARLY
STATIONARY...WHILE PRODUCING SNOWFALL RATES UP TO 5 INCHES PER HOUR.
AFTER A BRIEF LULL IN THE ACTION...ANOTHER BAND OF VERY HEAVY LAKE
EFFECT SNOW FORMED OFF LAKE ERIE LATER ON THE 19TH AND PRODUCED
UPWARDS OF ANOTHER 4 FEET OF SNOW ACROSS SOME OF THE SAME AREAS BY
THE 21ST. THIS SECOND SNOW BAND WAS SIMILAR TO THE FIRST SNOW BAND
IN THAT IT AGAIN REMAINED NEARLY STATIONARY WITH VERY HIGH SNOWFALL
RATES. ONE DIFFERENCE WAS THAT THE SECOND EVENT`S AXIS OF HEAVIEST
SNOWFALL WAS JUST A FEW MILES SOUTH FROM THE AXIS OF HEAVIEST SNOW
WITH THE FIRST EVENT. IN TOTAL 5 TO 7 FEET OF SNOW SMOTHERED TOWNS
JUST TO THE SOUTH OF THE BUFFALO AIRPORT...WHILE JUST OVER A FOOT OF
SNOW WAS MEASURED ON THE AIRPORT GROUNDS. MANY TOWNS SOUTH OF THE
AIRPORT HAD TRAVEL BANS THAT LASTED DAYS...WITH ALL MAJOR ROADS IN
AND AROUND BUFFALO CLOSED FOR A PERIOD OF TIME. THERE WAS A VERY
SHARP GRADIENT TO THE SNOWFALL THAT FELL THROUGH THE WEEK...WITH
AREAS TO THE NORTH OF THE AIRPORT RECEIVING A FOOT OR LESS OF
SNOWFALL.

AFTER THIS EPIC EVENT...TEMPERATURES BY MONDAY THE 24TH CLIMBED INTO
THE 60S...WHICH QUICKLY MELTED A PORTION OF THE SNOW THAT FELL THE
PRIOR WEEK. THE ABLATION OF THE SNOWPACK BROUGHT MINOR FLOODING ON
LOCAL CREEKS AND RIVERS...BUT URBAN FLOODING WAS HELD IN CHECK AS A
STILL SIZABLE SNOWPACK REMAINED ACROSS THE BUFFALO SOUTHTOWNS.

SOUTHWEST WINDS DOMINATED THE MONTH...AND THESE WINDS WERE A BIT
GUSTY AS THE MONTHLY WINDS AVERAGED 12.2 MPH. HIGHEST WINDS WERE ON THE
24TH IN WHICH A GUST TO 52 MPH WAS REGISTERED AT THE AIRPORT. LAKE
ERIE FINISHED THE MONTH AT 40F...THOUGH IT DID DROP TO 39F FOR A DAY
AFTER THE EPIC LAKE EFFECT SNOW STORMS. THIS 39F READING IS THE
FIRST SUCH READING IN THE 30S IN NOVEMBER SINCE NOVEMBER OF 1976.

IN ALL...A COLD NOVEMBER...THAT WILL LONG BE REMEMBERED FOR THE
HISTORIC 7 FEET OF SNOW ACROSS THE SOUTHTOWNS.
