...CHILLY MARCH FOLLOWING MILD WINTER...

AFTER A MILD WINTER ACROSS THE GREAT LAKES, ARCTIC AIR POURED OVER
THE REGION, PRODUCING A MARCH THAT FINISHED LESS THAN A DEGREE
WARMER THAN THE AVERAGE OF THE 2016-17 METEOROLOGICAL WINTER MONTHS
OF DECEMBER, JANUARY AND FEBRUARY. MARCH, COLDER THAN FEBRUARY FOR
JUST THE 11TH TIME IN RECORDED HISTORY, WAS ALSO THE FIRST BELOW
NORMAL TEMPERATURE MONTH SINCE APRIL 2016. THERE WERE THREE NOTABLE
WEATHER EVENTS THIS MONTH. THE FIRST WAS A HIGH WIND EVENT THAT
BROUGHT A CONSIDERABLE AMOUNT OF DAMAGE ACROSS WESTERN NEW YORK. THE
NEXT TWO WERE PRECIPITATION EVENTS, A NOR`EASTER THAT DROPPED OVER A
FOOT AND A HALF OF SNOW MID-MONTH, AND FINALLY A LONG DURATION RAIN
EVENT WITH OVER AN INCH OF RAIN TO CLOSE OUT MARCH.

THE AVERAGE TEMPERATURE IN MARCH WAS 33.0F, WHICH IS A FULL DEGREE
BELOW NORMAL. THERE WERE 16 DAYS BELOW NORMAL IN MARCH, WITH THE
BULK OF THESE DAYS CENTERED MID-MONTH. THREE DAYS THIS MONTH REACHED
INTO THE 60S, WHICH IS NORMAL. THERE WERE TWO BRIEF WARM SPELLS THIS
MONTH, THE FIRST FROM THE 6TH TO THE 8TH AND THE SECOND FROM THE
24TH TO 28TH. NO DAILY RECORD TEMPERATURES WERE SET THIS MONTH.

PRECIPITATION FOR THE MONTH TOTALED 4.36 INCHES, WHICH WAS THE 14TH
WETTEST MARCH ON RECORD. SNOWFALL TOTALED 26.8 INCHES WHICH IS GOOD
FOR THE 7TH SNOWIEST MARCH ON RECORD. THERE WERE 15 DAYS THAT HAD
MEASURABLE PRECIPITATION THIS MONTH...ABOUT AVERAGE. HOWEVER OF
THESE 15 DAYS, 11 HAD AT LEAST A TENTH OF AN INCH OF PRECIPITATION
WHICH IS JUST TWO DAYS LESS THAN THE RECORD OF 13. THERE WERE TWO
DAILY SNOWFALL RECORDS ESTABLISHED, THE FIRST ON THE 14TH (13.2
INCHES) AND A SECOND THE FOLLOWING DAY ON THE 15TH (4.9 INCHES).

MARCH CAME IN LIKE A LION, AS A STORM SYSTEM CUT BY WESTERN NEW YORK
TO THE NORTHWEST. THIS SYSTEM BROUGHT WIND GUSTS OVER 50 MPH TO THE
NIAGARA FRONTIER. WARM AIR AHEAD OF THE SURFACE LOW ALSO BROUGHT
TEMPERATURES INTO THE LOWER 60S ACROSS THE BUFFALO METRO AREA TO
START THE MONTH. HOWEVER THIS WARMTH FLEETED QUICKLY, WITH THE NEXT
FOUR DAYS REMAINING IN THE 20S AND 30S FOR HIGHS. ON THE MORNING OF
THE 5TH THE MERCURY DROPPED TO 7F DEGREES, THE COLDEST MORNING THIS
MONTH. AFTER A RETURN TO MILD TEMPERATURES THE 6TH THROUGH 8TH, A
SEVERE WIND EVENT OCCURRED ACROSS WESTERN NEW YORK ON WEDNESDAY THE
8TH. THIS WIND EVENT WAS NOT A CLASSIC EVENT AS THE SURFACE LOW
REMAINED FAR AWAY FROM THE EASTERN GREAT LAKES REGION. RATHER A VERY
STRONG LOW LEVEL JET FLOWED ACROSS THE REGION, WITH SUNSHINE
INCREASING THE MIXING LAYER, SUCH THAT THESE STRONG WINDS ALOFT WERE
TRANSPORTED TO THE SURFACE. THE NEARBY COOLER LAKE ERIE WATERS
ACTUALLY SHELTERED THE METRO BUFFALO AREA FROM THE BRUNT OF THIS
EVENT, WITH WIND GUSTS REACHING INTO THE UPPER 60 MPH RANGE AND
SCATTERED WIND DAMAGE. FARTHER INLAND, THE DAMAGE WAS MUCH MORE
SEVERE.

THE FOLLOWING TUESDAY AND WEDNESDAY, THE 14TH AND 15TH, A NOR`EASTER
DEVELOPED, DROPPING WIDESPREAD SNOW ACROSS THE REGION. THOUGH THE
INITIAL ROUND OF SNOW WAS MANAGEABLE, THE CONSTANT FLOW OF MOISTURE
ACROSS LAKE ONTARIO, AND FALLING TEMPERATURES BROUGHT CONTINUAL LAKE
ENHANCED SNOW, SUCH THAT BY TIME ALL WAS SAID AND DONE ON THE 15TH,
19.6 INCHES OF SNOW WAS MEASURED AT THE BUFFALO AIRPORT. THE
SNOWDEPTH DECREASED RAPIDLY, THANKS TO A STRONG MARCH SUN ANGLE AND
DAYTIME TEMPERATURES RISING ABOVE FREEZING. THIS SNOW ABLATED JUST A
WEEK LATER, BEFORE SEVERAL RAIN EVENTS IMPACTED WESTERN NEW YORK.
THIS FIRST EVENT BROUGHT NEARLY AN INCH OF RAINFALL TO WESTERN NEW
YORK ON THE 24TH AND 25TH. A SECOND EVENT, WITH GREATER RAINFALL,
REACHED THE REGION AT THE END OF THE MONTH WITH ONE TO ONE AND A
HALF INCHES OF RAIN FALLING ACROSS WESTERN NEW YORK.

LAKE ERIE, WHICH NEVER FROZE THIS YEAR FLUCTUATED BETWEEN 33 AND 36F
THROUGH THE MONTH. THE STRONGEST WIND GUST WAS 66 MPH ON THE
AFTERNOON OF THE 8TH, AND A GUSTY WIND THROUGH THE MONTH BROUGHT THE
AVERAGE WIND SPEED TO 11.6 MPH, WHICH IS ALMOST A HALF A MILE PER
HOUR ABOVE NORMAL.

IN ALL, AN ACTIVE AND COOL MONTH.
