...MODERATE SWINGS IN FEBRUARY...

A TYPICAL FEBRUARY PREVAILED TO CLOSE THE METEOROLOGICAL WINTER WITH
NO EXTREMES IN TEMPERATURE. LAKE EFFECT SNOW WAS COMMON TO BEGIN THE
MONTH...AND A SLOW MOVING SYNOPTIC SYSTEM BROUGHT RAIN AND THEN SNOW
TOWARDS THE END OF THE MONTH. IN ALL TEMPERATURES FINISHED NEAR
NORMAL WHILE PRECIPITATION FINISHED JUST ABOVE NORMAL.

THERE WERE NO MAJOR TEMPERATURE SWINGS THIS MONTH AND NO RECORD
EXTREMES. THE AVERAGE TEMPERATURE OF 26.8F WAS JUST A FRACTION ABOVE
THE NORMAL OF 26.4F. THE WARMEST DAY THIS MONTH WAS ON THE 11TH WHEN
THE MERCURY REACHED 51F. THE COOLEST DAY OCCURRED ONE DAY EARLIER
WITH 3F FOR THE MINIMUM TEMPERATURE.

THERE WERE NO DAYS THIS MONTH PRECIPITATION FREE...AND THE 19 DAYS
OF MEASURABLE PRECIPITATION IS ABOUT 3 MORE THAN NORMAL. THERE WAS
ONE DAILY SNOWFALL RECORD WHEN 10.1 INCHES OF SNOW FELL ON THE 8TH.
MUCH OF THE SNOW FELL PRIMARILY THE FIRST 10 DAYS OF THE MONTH
LEADING TO A MONTHLY TOTAL OF 28.8 INCHES WHICH IS ABOUT 7 INCHES
ABOVE NORMAL.

A COLD WAVE TO START THE MONTH BROUGHT LIGHT SNOWS OF UNDER 2 INCHES
THROUGH THE FIRST WEEK. AN UPPER LEVEL SYNOPTIC LOW BROUGHT
WIDESPREAD SNOW ACROSS WESTERN NEW YORK ON THE 8TH WITH AROUND A
FOOT OF SNOW FALLING ACROSS THE ROCHESTER METRO AREA. AHEAD OF A
COLD FRONT TEMPERATURES SOARED INTO THE LOW 50S ON MONDAY THE
11TH...FOLLOWED BY GUSTY WINDS NEAR 50 MPH THROUGH THE EVENING AND
OVERNIGHT HOURS. ANOTHER THAW AND GUSTY WIND EVENT CAME A WEEK LATER
ON THE 19TH THOUGH NOT AS DRAMATIC. THE LAST WEEK OF THE MONTH A
SLOW MOVING SYNOPTIC LOW BROUGHT HEAVY RAIN INTO THE ROCHESTER METRO
AREA ON THE EVENING OF THE 26TH...THAT CHANGED TO A MIX OF LIGHT
RAIN AND SNOW TO CLOSE THE MONTH.

SUNSHINE FOR THE MONTH FINISHED 9 PERCENT BELOW THE NORMAL OF 38
PERCENT. THERE WERE 3 MOSTLY SUNNY DAYS...OTHERWISE THE REMAINDER OF
THE MONTH WAS CLOUDY OR PARTLY SUNNY.

IN ALL THIS WAS A TYPICAL FEBRUARY WITH NEAR NORMAL TEMPERATURES AND
PRECIPITATION THAT FINISHED JUST ABOVE NORMAL AND WAS BOTH THE LAKE
EFFECT AND SYNOPTIC VARIETY.


...WINTER (DEC-FEB) 2012-13

AFTER THE EXTREME WINTER OF LAST YEAR THIS WINTER FOR WESTERN NEW
YORK WILL COMPARE CLOSER TO NORMAL...THOUGH TEMPERATURES WERE STILL
ABOVE NORMAL...AND SNOWFALL WELL BELOW NORMAL. TEMPERATURES AVERAGED
MORE THAN 5 DEGREES ABOVE NORMAL FOR THE MONTHS OF DECEMBER AND
JANUARY...VERY SIMILAR TO THE PREVIOUS WINTER. HOWEVER FEBRUARY
RETURNED CLOSER TO A TRUE WINTER WITH TEMPERATURES THAT AVERAGE NEAR
NORMAL AND SNOWFALL AVERAGING JUST ABOVE MONTHLY NORMAL. THE BULK OF
THE SEASONS SNOWFALL CAME DURING THE LAST 10 DAYS OF DECEMBER AND
THE FIRST 10 DAYS OF FEBRUARY.

THERE WERE TWO NOTABLE SYNOPTIC SNOW EVENTS THIS WINTER. THE FIRST
CAME THE DAY AFTER CHRISTMAS WITH CLOSE TO A FOOT OF SNOW FALLING
ACROSS WESTERN NEW YORK. THE MONTH OF JANUARY FINISHED WITH VERY
LITTLE SNOWFALL...AFTER WHICH ANOTHER SYNOPTIC EVENT BROUGHT JUST
OVER HALF A FOOT OF SNOW TO THE ROCHESTER AREA ON FEBRUARY 8TH.
SEVERAL MODERATE LAKE EFFECT EVENTS WITH AN UPSTREAM CONNECTION
OCCURRED THROUGH THE WINTER SEASON.

HERE ARE SOME STATISTICS FOR THE 3 MONTH WINTER PERIOD FOR ROCHESTER...
(NORMALS)

TEMPERATURE.... 31.0 (27.0) **13TH WARMEST**
PRECIPITATION.. 7.90 (6.99)
SNOWFALL....... 63.1 (71.5)
