...A COLD JANUARY WITH ACTIVE SNOWS...

JANUARY WAS A COLD WINTER MONTH ACROSS WESTERN NEW YORK AS COLD
WEATHER PATTERNS TOOK THE UPPER HAND OVER ANY ATTEMPTS OF A WINTER
RESPITE FROM THE FRIGID TEMPERATURES. LAKE EFFECT SNOW DOMINATED THE FIRST
HALF OF THE MONTH...BEFORE A SUBTLE SHIFT IN THE WINDS AND CHANGE IN
THE WEATHER PATTERN ALLOWED FOR NICKEL AND DIME SNOWS THROUGH THE
REMAINDER OF THE MONTH.

THE AVERAGE TEMPERATURE THIS MONTH WAS 20.4F DEGREES WHICH IS FOUR
AND A HALF DEGREES BELOW NORMAL. THIS MADE JANUARY THE 28TH COLDEST
IN 145 YEARS. THERE WERE 14 DAYS THAT DROPPED INTO THE SINGLE DIGITS
THIS MONTH...TWO FEWER THAN LAST JANUARY...BUT 6 MORE DAYS THAN
NORMAL. TEMPERATURE RECORDS THAT WERE PREVIOUSLY ESTABLISHED IN
JANUARY STOOD THROUGH THE MONTH.

PRECIPITATION FOR THE MONTH WAS ABOUT A HALF INCH BELOW
NORMAL...WITH SNOWFALL JUST THREE TENTHS OF AN INCH BELOW NORMAL.
THERE WAS ONE RAINSTORM THIS MONTH...ON THE 3RD-4TH...OTHERWISE MUCH
OF THE PRECIPITATION THAT FELL THIS MONTH WAS SNOW. WHILE THERE WERE
NO SNOWFALL RECORDS THIS MONTH...THE SNOWFALL ON THE 9TH DID CROSS
THE HALF FOOT MARK...COMING IN AT 6.5 INCHES. ALL BUT TWO DAYS HAD
AT LEAST A TRACE OF PRECIPITATION THIS MONTH. MEASURABLE SNOWFALL ON
20 DAYS THIS MONTH WAS 5 MORE THAN NORMAL.

THE NEW YEAR BEGAN WITH LAKE EFFECT SNOW DOWNWIND OF THE EASTERN
GREAT LAKES ON A GUSTY SOUTHWEST WIND. THIS WIND PROVED TOO STRONG
FOR A HEALTHY BAND OF LAKE SNOW TO DEVELOP...THOUGH SEVERAL INCHES
DID COAT WESTERN NEW YORK NEW YEARS DAY. THE NEXT THREE DAYS OF
JANUARY WERE ATYPICAL FOR THE MONTH AS A WHOLE...AS A SOUTHERLY FLOW
AND ABOVE NORMAL TEMPERATURES WERE COUPLED WITH A SOAKING RAINFALL.
OVER AN INCH OF RAIN FELL ACROSS WESTERN NEW YORK ON THE 3RD AND
4TH...WITH THE GREATEST RAINFALL AMOUNTS FOUND JUST TO THE NORTHEAST
OF LAKE ERIE. A SURGE OF VERY COLD AIR REACHED THE EASTERN GREAT
LAKES ON THE 5TH...AND REMAINED ACROSS THE REGION FOR THE BETTER
PART OF A WEEK. THIS COLD AIRMASS PRODUCED THREE MODERATE LAKE
EFFECT SNOW EVENTS EAST OF LAKE ERIE WITH EACH EVENT DROPPING
BETWEEN ONE AND TWO FEET OF SNOW.

BY MID MONTH THE ARCTIC AIRMASS RETREATED AND A WESTERLY FLOW
RETURNED ACROSS THE EASTERN GREAT LAKES REGION. THIS WESTERLY FLOW
CONCENTRATED THE ARCTIC COLD WELL TO OUR NORTH...ALLOWING WESTERN
NEW YORK TO CYCLE THROUGH TEMPERATURES NEAR NORMAL. WITHIN THIS
WESTERLY FLOW...THERE WERE SEVERAL SYNOPTIC CLIPPERS THAT CROSSED
THE REGION (12TH, 26-27TH AND 29TH-30TH) WITH TYPICAL LIGHT
SNOWFALLS.  ON THE 24TH WIDESPREAD LIGHT FREEZING RAIN AND DRIZZLE
GLAZED WESTERN NEW YORK WITH HUNDREDS OF CARS SLIDING OFF THE
ROADWAYS. AN  AREA OF HIGH PRESSURE BROUGHT CRYSTAL CLEAR BLUE SKIES
ON WEDNESDAY JANUARY 28TH. COLD AIR RETURNED FOR GOOD AT THE END OF
THE MONTH WITH 4 OF THE LAST 5 DAYS DIPPING INTO THE SINGLE DIGITS.

LAKE ERIE FROZE ON JANUARY 9TH THIS YEAR...ABOUT A WEEK AHEAD OF
NORMAL. GUSTY WINDS OVER 50 MPH SWEPT ACROSS WESTERN NEW YORK ON THE
1ST AND 4TH...OTHERWISE WINDS WERE LIGHT TO MODEST THE REMAINDER OF
THE MONTH.

IN ALL JANUARY WAS BITTERLY COLD WITH TYPICAL SNOWS THROUGH
THE MONTH.
