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. && THOMAS $$
