...CONTINUED COLD AND SNOWY...

THE MONTH OF MARCH CONTINUED THIS WINTERS THEME OF SNOW AND ABUNDANT
COLD DAYS ACROSS WESTERN AND NORTH CENTRAL NEW YORK. THE OVERALL
PATTERN ALOFT OF A RIDGE IN THE WESTERN US AND TROUGH OVER THE EAST
PROMOTED A MONTH WHOSE MEAN TEMPERATURE WAS WELL BELOW NORMAL.
SEVERAL SYNOPTIC SNOW STORMS...WHICH WHEN COMBINED WITH MINOR LAKE
EFFECT SNOW EVENTS...BROUGHT WELL ABOVE NORMAL MARCH SNOW.

THE AVERAGE TEMPERATURE THIS MONTH WAS 27.7F WHICH IS TIED FOR THE
14TH COLDEST MONTH OF MARCH ON RECORD. THERE WERE 21 DAYS THIS MONTH
THAT AVERAGED BELOW NORMAL...AND ONE NEW RECORD LOW TEMPERATURE SET.
ON THE MORNING OF MARCH 6TH THE TEMPERATURE DROPPED TO
-9F...BREAKING THE OLD RECORD BY 6 DEGREES FROM 1948. THIS -9F
READING IS ALSO THE COLDEST TEMPERATURE EVER RECORDED IN ROCHESTER
IN THE MONTH OF MARCH. THE PREVIOUS RECORD WAS -7F SET BACK IN MARCH
OF 1872. THERE WERE 6 DAYS THAT RECORDED SINGLE DIGIT OR COLDER LOWS
WHICH IS 4 MORE THAN THE NORMAL FOR MARCH. BROADENING TO THE ENTIRE
WINTER SEASON THERE WERE 39 DAYS WITH SINGLE DIGIT OR COLDER LOWS
WHICH IS THE GREATEST NUMBER OF DAYS WITH SUCH MEASUREMENT SINCE
RECORDS MOVED TO THE AIRPORT IN 1939...AND 5TH GREATEST ALL-TIME.
THERE WERE TWO DAYS THIS MONTH THAT DROPPED BELOW ZERO...A FEAT THAT
HAS ONLY OCCURRED 6 TIMES IN MARCH SINCE 1871.

PRECIPITATION FOR THE MONTH OF MARCH AVERAGED JUST BELOW NORMAL WITH
2.36 INCHES RECORDED. THERE WERE 15 DAYS OF MEASURABLE PRECIPITATION
WHICH IS ABOUT NORMAL. MUCH OF THE PRECIPITATION RECORDED THIS MONTH
FELL AS SNOW WITH THE GREATEST PRECIPITATION AMOUNT OCCURRING ON THE
12TH.

SNOWFALL THIS MONTH WAS NEARLY TWICE THAT OF NORMAL...WITH 29.3
INCHES MEASURED. THIS MAKES MARCH 2014 AS 15TH SNOWIEST MARCH ON
RECORD. ON THE 12TH 14.9 INCHES OF SNOW FELL...MAKING FOR THE FIRST
TIME SINCE 1999 THAT OVER A FOOT OF SNOW WAS MEASURED IN THE MONTH
OF MARCH. THIS TOTAL WAS ALSO THE GREATEST CALENDAR DAY SNOW OF THIS
WINTER SEASON.

A COLD FRONT CROSSED WESTERN NEW YORK LATE ON THE 1ST AND SENT THE
REGION BACK INTO GRIP OF WINTER...WITH LIGHT SNOW AND FRIGID
TEMPERATURES. HIGHS ON THE 2ND THROUGH 5TH AVERAGED ONLY BETWEEN 13
AND 21 DEGREES...WHICH IS ABOUT 20 DEGREES BELOW NORMAL.
TEMPERATURES WOULD REMAIN BELOW THE FIRST WEEK OF THE MONTH. OUR
FIRST EARLY TASTE OF SPRING OCCURRED ON THE 10TH AND 11TH. A STALLING
AND WEAKENING COLD FRONT...COMBINED WITH THE INCREASING EFFECTS OF
DAYTIME HEATING BROUGHT HIGHS INTO THE LOW 50S BY TUESDAY THE 11TH.
ON TUESDAY NIGHT AND WEDNESDAY A STRONG LATE WINTER SNOWSTORM
DEVELOPED...ONE THAT BROUGHT BLIZZARD CONDITIONS ACROSS WESTERN NEW
YORK. THIS SYSTEM DUMPED A FOOT TO FOOT AND A HALF OF SNOW ACROSS
WESTERN NEW YORK AND STRONG WINDS BROUGHT FREQUENT WHITEOUT
CONDITIONS. BEHIND THIS SYSTEM A TYPICAL ROLLER COASTER OF
TEMPERATURES OCCURRED THROUGH THE END OF THE MONTH...THOUGH THE
NUMBER OF BELOW NORMAL DAYS OUTWEIGHED THE ABOVE NORMAL DAYS ABOUT 3
TO 1. A STORM SYSTEM ON THE EVENING OF THE 29TH TO THE MORNING OF
THE 30TH BROUGHT A HEAVY WET SNOW ACROSS WESTERN NEW YORK.
TOTALS...SOMEWHAT HIGHER ACROSS HIGHER TERRAIN AVERAGED 6 TO 10
INCHES ACROSS THE GENESEE VALLEY.

SUNSHINE THIS MONTH AVERAGED 54 PERCENT...WHICH IS 8 PERCENT MORE
THAN NORMAL. THERE WERE 15 MOSTLY SUNNY DAYS CONTRIBUTING TO THE
ABOVE NORMAL SUNSHINE. WINDS WERE GENERALLY TAME THIS MONTH
AVERAGING ABOUT ONE MPH LESS THAN NORMAL. TYPICAL ICE ON THE EASTERN
PORTION OF LAKE ONTARIO EXPANDED WESTWARD...WITH ICE NOT ONLY ALONG
THE SHORELINE BUT ALSO ACROSS PORTIONS OF CENTRAL LAKE ONTARIO NORTH
OF ROCHESTER IN EARLY MARCH.

IN ALL ANOTHER COLD MONTH WITH FREQUENT SNOWS.
