YEAR WAS ABOUT 4 WEEKS LATER THAN NORMAL, AND SIGNIFIED ONE OF THE
LATER WINTER THAWS ON RECORD.
PRECIPITATION TOTALED 2.29 INCHES FOR THE MONTH WHICH IS ABOUT TWO-
TENTHS OF AN INCH ABOVE NORMAL. PRECIPITATION THROUGH THE FIRST
THREE WEEKS WAS GENERALLY SNOW OR LIGHT FREEZING RAIN, BUT BY THE
LAST WEEK MILDER AIRMASSES BEGAN TO REINTRODUCE PLAIN RAIN TO
WESTERN NEW YORK. THROUGH THE FIRST 15 DAYS OF THE MONTH, 5 DAYS

WESTERN NEW YORK ON THE 5TH BECAME ALL SNOW LATE ON THE 5TH AND 6TH
AS A STRONG COLD FRONT WITH GUSTS IN THE 50 MPH RANGE SWEPT ACROSS
THE STATE. FEBRUARY 15TH AND 16TH BROUGHT A WINTRY MIX TO WESTERN
NEW YORK WITH SNOW CHANGING TO FREEZING RAIN AND PLAIN RAIN. A TENTH
OR TWO OF AN INCH OF ICE DEVELOPED ON SUNDAY THE 16TH ACROSS METRO
ROCHESTER. BEHIND THIS SYSTEM A BITTER COLD AIRMASS DROPPED ACROSS
THE EASTERN GREAT LAKES REGION, SENDING TEMPERATURES DOWN INTO THE
SINGLE DIGITS WHICH ALONG WITH BRISK WINDS SENT WIND CHILLS BELOW

WEEK FEATURED A WARMING TREND WHICH ERODED THE DEEP SNOWPACK THAT
WAS BUILDING THROUGH THE MONTH. A PEAK OF 9-INCH SNOW DEPTH ON THE
22ND BECAME A DEPTH OF JUST 2 INCHES BY THE MORNING OF THE 26TH.
WARM GUSTY WINDS ON THE 24TH DID MUCH OF THE SNOWPACK ABLATION.
LIGHT RAIN SHOWERS THE FINAL 4 DAYS OF THE MONTH RIPENED THE
SNOWPACK ACROSS WESTERN NEW YORK. MINOR ICE JAMS OCCURRED THE FINAL
TWO DAYS OF THE MONTH, BUT WITH LITTLE IMPACT AS CREEKS AND RIVERS
REMAINED WITH LOW FLOW.
SHORELINE ICE REMAINED ALONG THE SOUTHERN SHORE OF LAKE ONTARIO THIS
MONTH. THE WINDS AVERAGED ABOVE NORMAL THIS MONTH WITH THE STRONGEST
GUST OCCURRING EARLY ON THE 7TH AT 53 MPH BEHIND A COLD FRONT
PASSAGE.
IN ALL A MONTH OF NUMEROUS LIGHT TO MODERATE PRECIPITATION EVENTS.
