THE METEOROLOGICAL WINTER OF 2012/13 WAS PRETTY MUCH AS NORMAL AS
ONE COULD EXPECT. THE DECEMBER THROUGH FEBRUARY 90 DAY AVERAGE
TEMPERATURE OF 12.7 DEGREES WAS 0.1 DEGREE ABOVE NORMAL.
STATISTICALLY THAT IS RIGHT IN THE MIDDLE OF THE SEASONAL PACK. THIS
IS QUITE A DIFFERENCE FROM A YEAR AGO WHEN THE AVERAGE TEMPERATURES
WAS ALMOST 10 DEGREES WARMER.

SNOWFALL WAS PRETTY CLOSE TO THE 1981 - 2010 MEDIAN VALUE AS
WELL.THE 28.7 INCHES THAT FELL IN THE PAST 3 MONTHS IS 0.7 INCHES
BELOW AVERAGE. THE AVERAGE SNOW DEPTH OF 5 INCHES IS A TAD BEHIND
THE 7 INCH AVERAGE ONE MIGHT EXPECT...AGAIN PRETTY MUCH NORMAL.

TOTAL LIQUID PRECIPITATION FOR THE LAST 90 DAYS WAS 2.56 INCHES OR
ONLY 0.42 INCHES ABOVE THE 30 YEAR AVERAGE.

MORE THAN HALF THE DAYS SAW LIGHT SNOWFALL IN THE F/M AREA WHICH IS
A BIT MORE FREQUENT THAN NORMAL. HOWEVER MOST DAYS THE ACCUMULATIONS
WERE PRETTY LIGHT.

THE AVERAGE WIND SPEED WAS 10.5 MPH AND THE STRONGEST GUST WAS 49
MPH FROM THE NORTHWEST ON THE 18TH OF FEBRUARY.

REMEMBER...THIS DATA IS PROVISIONAL AND SUBJECT TO CHANGE. THE FINAL
AND OFFICIAL RECORDS WILL BE AVAILABLE FROM THE NATIONAL CLIMATIC
DATA CENTER.
