..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.
