...PERSISTENTLY COLD MARCH...

FOR A SECOND YEAR IN A ROW MARCH 2018 FINISHED COOLER THAN THE
PREVIOUS FEBRUARY AS A PERSISTENT TRACK OF STORMS WENT MAINLY TO OUR
SOUTH AND EAST. SNOW FELL PRIMARILY THE FIRST HALF OF THE MONTH...A
MONTH THAT FEATURED MOST OF ITS DAYS WITH HIGHS IN THE 30S.

THE AVERAGE TEMPERATURE WAS 32.2F THIS MONTH, WHICH IS JUST 2.1
DEGREES BELOW NORMAL. THOUGH HIGH TEMPERATURES REMAINED IN THE 30S
FOR MUCH OF THE MONTH, CLOUDY SKIES LIMITED THE COOLING
OVERNIGHT...WITH THE AVERAGE MINIMUM TEMPERATURE FINISHING A HALF A
DEGREE ABOVE NORMAL. THERE WERE JUST 9 DAYS THAT REACHED THE 40F
MARK...WELL BELOW THE NORMAL OF 16.

PRECIPITATION TOTALED 3.02 INCHES, WHICH IS ABOUT A HALF AN INCH
ABOVE NORMAL. SNOWFALL TOTALED 29.4 INCHES AND FELL MAINLY IN THE
FIRST HALF OF THE MONTH AND WAS OVER A FOOT ABOVE THE NORMAL OF 16.3
INCHES.

THE FIRST NOR`EASTER OF THE MONTH BROUGHT THE GREATEST IMPACT TO
WESTERN NEW YORK ON THE 1ST AND 2ND OF THE MONTH. THE 11.5 INCHES OF
SNOW ON THE 2ND WAS THE GREATEST CALENDAR SNOWFALL THIS WINTER
SEASON. IN TOTAL, THERE WERE 4 NOR`EASTERS THAT EFFECTED THE
NORTHEAST THIS MONTH. THEREAFTER, STORMS TRACKED TO THE SOUTH AND
EAST OF THE REGION...LEAVING WESTERN NEW YORK IN A PERSISTENT COOL
PATTERN. THOUGH THERE WERE MANY SUNNY DAYS, THE SNOWPACK ONLY
GRADUALLY ABLATED OWING TO TEMPERATURES JUST ABOVE FREEZING AND DRY
AIRMASSES. THE 23 DAYS WITH A SNOW DEPTH OF 3 INCHES OR MORE WAS 4TH
GREATEST, AND MOST SINCE 1993. A FEW SNOW SHOWERS PASSED THROUGH MID-
MONTH...THE BULK OF WHICH CAME WITH ANOTHER NOR`EASTER ON THE 13TH-
15TH THAT DROPPED NEAR A FOOT OF SNOW ACROSS THE ROCHESTER METRO
AREA. A WARM FRONT LIFTED THROUGH THE REGION ON THE 26TH, BRINGING
TEMPERATURES INTO THE UPPER 40S. THIS BOUNDARY STALLED ACROSS THE
REGION THROUGH THE REMAINDER OF THE MONTH...SERVING AS A FOCUS FOR
LIGHT RAIN TO FALL EACH DAY.

STRONGEST WINDS CAME AT THE VERY BEGINNING AND END OF THE MONTH,
WITH GUSTS ON THE 1ST, 2ND AND 31ST ALL TOPPING THE 40 MPH MARK. THE
STRONGEST GUST WAS 48 MPH ON THE 2ND.

IN ALL, A CHILLY MONTH WITH A DREARY FINISH.
