...NEAR-SNOWLESS NOVEMBER...

A CONSTANT FLOW OF PACIFIC AIR BOTTLED COLDER AIR WELL TO THE NORTH
THIS MONTH, WITH THE ONE TRUE, BRIEF SURGE OF ARCTIC AIR MID-MONTH
PRODUCING THE ONLY MEASURABLE SNOWFALL...AMOUNTING TO A TENTH OF AN
INCH AT THE BUFFALO AIRPORT. THERE WERE SEVERAL SOAKING RAINFALL
EVENTS THROUGH THE MONTH THAT BROUGHT NOVEMBER`S TOTAL PRECIPITATION
TO OVER AN INCH ABOVE NORMAL.

THE MONTHLY TEMPERATURE AVERAGED 39.8F WHICH IS ABOUT A DEGREE BELOW
NORMAL. THERE WAS ONE BRIEF ARCTIC BLAST THIS MONTH, THIS ON THE 10-
11TH. A RECORD LOW MAXIMUM TEMPERATURE OF 29F WAS SET ON THE 10TH
(BREAKING THE RECORD OF 30F/1877), AND A RECORD LOW TEMPERATURE OF
19F WAS TIED ON THE 11TH (TIED 19F/1957). THE FIRST 32F READING OF
THE COOL SEASON OCCURRED ON NOVEMBER 7TH. THIS MADE FOR 212
CONSECUTIVE DAYS ABOVE FREEZING...WHICH TIED FOR THE 5TH LONGEST
STREAK.

PRECIPITATION TOTALED 5.09 INCHES FOR THE MONTH. MUCH OF THIS
PRECIPITATION OCCURRED OVER THE 2ND THROUGH THE 6TH, INCLUDING A NEW
DAILY RECORD OF 2.01 INCHES ON THE 5TH. THE PRECIPITATION ON THE 6TH
WAS THE LAST DAY IN 10 CONSECUTIVE DAYS OF MEASURABLE PRECIPITATION
AT BUFFALO. THERE WERE 17 DAYS WITH MEASURABLE PRECIPITATION, 2 DAYS
GREATER THAN NORMAL. THERE WAS JUST ONE DAY WITH MEASURABLE SNOW,
THIS A 0.1 OF AN INCH ON THE 10TH. THIS IS THE THIRD NOVEMBER IN A
ROW WITH LESS THAN AN INCH OF SNOW.

THE MONTH OF NOVEMBER CONTINUED THE WET PATTERN FROM THE END OF
OCTOBER, WITH 6 CONSECUTIVE DAYS OF RAIN CREATING A SOGGY GROUND
ACROSS WESTERN NEW YORK. HIGH PRESSURE THEN BROUGHT COOLER, BUT MUCH
DRIER WEATHER FROM THE 7TH THROUGH THE MORNING OF THE 9TH. A SHARP
COLD FRONT CROSSED WESTERN NEW YORK LATER ON THE 9TH, AND USHERED IN
THE COLDEST AIR OF THE WINTER SEASON THUS FAR FOR THE 10TH AND 11TH.
THIS COLD AIRMASS ALSO PRODUCED THE FIRST MEASURABLE SNOWFALL FOR
BUFFALO, WITH 0.1 INCHES ACCUMULATING ON THE 10TH.

COOL AND UNSETTLED WEATHER REMAINED ACROSS WESTERN NEW YORK MID-
MONTH. THE FIRST LAKE EFFECT SNOW EVENT OCCURRED ON SUNDAY THE 19TH
THROUGH MONDAY THE 20TH. BEHIND A COLD FRONT, LAKE EFFECT SNOW BEGAN
THROUGH THE MORNING HOURS SUNDAY EAST OF LAKE ERIE, WHILE OFF LAKE
ONTARIO, THE LAKE EFFECT SNOW BECAME HEAVIEST MONDAY MORNING WITH UP
TO A FOOT OF SNOW FALLING OVER THE SOUTHERN TUG HILL REGION. THOUGH
6 OF THE LAST 7 DAYS OF THE MONTH FINISHED ABOVE TEMPERATURE
NORMALS, INCLUDING 65F ON THE 28TH WITH GUSTY SOUTHERLY WINDS,
TEMPERATURES FOR NOVEMBER FINISHED BELOW NORMAL.

LAKE ERIE DROPPED 10 DEGREES THIS MONTH, FROM 55F DOWN TO 45F. WINDS
AVERAGED JUST BELOW NORMAL THIS NOVEMBER AND THERE WERE NO MAJOR
WIND EVENTS. THE STRONGEST WIND GUST WAS ON THE 9TH WHEN GUSTS
REACHED 46 MPH ALONG AN ARCTIC FRONT.

IN ALL A COOL, UNSETTLED MONTH FEATURING A LACK OF SNOW.
