..DRY, SUNNY AND WARM MARCH
MARCH CAME IN AND OUT LIKE A LION, WITH A PROLONGED STRETCH OF QUIET
WEATHER IN BETWEEN. ABUNDANT SUNSHINE AND BUILDING WARMTH MADE FOR
PLEASANT MID MONTH CONDITIONS. THE MONTH WILL ALSO BE NOTED FOR THE
LACK OF PRECIPITATION, BOTH SNOW AND RAINFALL, AND WHAT RAIN THAT
DID FALL ALMOST ENTIRELY OCCURRED THE LAST WEEK OF THE MONTH.
THE TEMPERATURE AVERAGED 39.3F DEGREES THIS MONTH, FINISHING 19TH
WARMEST ON RECORD. THE 11 DAYS WITH TEMPERATURES REACHING 60F OR
GREATER WAS TIED FOR 3RD GREATEST ON RECORD...WITH JUST THE YEARS OF
2012 (18 DAYS) AND 1946 (12 DAYS) CONTAINING MORE. THOUGH A WARM
MONTH, THERE WERE 10 DAYS THAT AVERAGED BELOW NORMAL. THERE WERE TWO
STRETCHES OF COLD MARCH TEMPERATURES, FROM THE 4TH THROUGH THE 8TH
AS WELL AS THE 13TH THROUGH THE 16TH. BETWEEN THESE TWO STRETCHES
DAILY RECORD HIGH TEMPERATURES OF 68F ON THE 10TH AND 71F ON THE
11TH WERE ESTABLISHED. ADDITIONALLY ON THE 25TH A RECORD WARM
MINIMUM TEMPERATURE OF 50F WAS SET.
IT WAS A VERY DRY MONTH OF MARCH, WITH THE TOTAL OF 1.02 INCHES FOR
THE MONTH A BIT DECEIVING AS ALL BUT 0.18 INCHES FELL THE LAST WEEK
OF THE MONTH. THIS 1.02 INCHES OF PRECIPITATION RANKS AS THE 8TH
DRIEST ON RECORD FOR MARCH. BY THE THIRD WEEK OF THE MONTH, THE
ROCHESTER AIRPORT WAS OFF TO ITS 10TH DRIEST START TO THE CALENDAR
YEAR. THIS DRY START BEGAN TO CHANGE WITH SEVERAL QUARTER TO HALF
INCH RAIN EVENTS ON THE 24TH AND 26TH. SNOW WAS LACKING, WITH THE
1.4 INCHES FOR THE MONTH TIED FOR 6TH LEAST MARCH SNOW AMOUNT ON
RECORD.
THE NEW MONTH STARTED ON THE MILD SIDE, BUT THIS WARM AIRMASS WAS
SHORT LIVED AS A STRONG COLD FRONT DROPPED ACROSS WESTERN NEW YORK
IN THE MID TO LATE AFTERNOON. TEMPERATURES PLUNGED AND A BLUSTERY
WIND BROUGHT SNOW SQUALLS ACROSS THE AREA. THE COLD AIRMASS
CONTINUED INTO THE 2ND, BUT BY THE 3RD, TEMPERATURES ROSE ABOVE
FREEZING AND MELTED WHAT LITTLE SNOWPACK THAT STARTED THE MONTH.
COLD AIR, SCATTERED FLURRIES AND LIGHT SNOW SHOWERS REMAINED ACROSS
WESTERN NEW YORK THROUGH THE 7TH. FOLLOWING THE PASSAGE OF A SURFACE
HIGH PRESSURE, SOUTHERLY WINDS BROUGHT IN MILDER AIR WITH THE
AFTERNOON TEMPERATURE ON THE 8TH RISING INTO THE UPPER 40S. BY THE
10TH, EARLY SPRING ACTIVITIES WERE ENJOYED AS TEMPERATURES SOARED
INTO THE UPPER 60S WITH PLENTY OF SUNSHINE. A COLD FRONT PRODUCED A
LINE OF SHOWERS AND THUNDERSTORMS THAT PASSED THROUGH WESTERN NEW
YORK LATE ON THE 11TH, THOUGH RAINFALL WAS MINIMAL. FOLLOWING THIS
COLD FRONT ANOTHER CHILLY AIRMASS GRIPPED WESTERN NEW YORK, BUT
SUNSHINE THROUGH THIS PERIOD TOOK THE EDGE OFF THE CHILL DURING THE
DAYLIGHT HOURS.
ANOTHER MILDER AIRMASS PUSHED NORTHWARD BY SUNDAY THE 21ST WITH
TEMPERATURES REACHING INTO THE 60S AGAIN. SOUTHERLY WINDS SUPPORTED
DAY TO DAY WARMING THIS THIRD WEEK OF THE MONTH WITH THE TEMPERATURE
ON THE 25TH MARKING THE WARMEST MAXIMUM TEMPERATURE FOR THE MONTH. A
MORNING LINE OF STORMS AIDED IN BENEFICIAL RAIN FOR THE 26TH, WITH
AROUND A HALF AN INCH OF RAIN FALLING ACROSS THE ROCHESTER METRO
AREA. SYNOPTIC WINDS INCREASED THROUGH THE DAY ON THE 26TH, WITH A
PEAK OF 58 MPH SET MIDDAY. THE FINAL DAYS OF THE MONTH ENDED WITH
SNOW FLURRIES AND GUSTY WINDS...SENDING MARCH OUT LIKE IT
STARTED...LIKE A LION.
LAKE ONTARIO WATER TEMPERATURE ROSE TO 41F AT THE END OF THE MONTH.
OVERALL THE AVERAGE WIND SPEED OF 11.1 MPH FOR THE MONTH WAS ALMOST
A MILE PER HOUR GREATER THAN NORMAL.
IN ALL A WARM, SUNNY MONTH WITH A FEW BOUTS OF WIND.
