...MILD AND WET OCTOBER...

OCTOBER WAS A TALE OF TWO SEASONS FOR ROCHESTER...WITH THE FIRST TWO
THIRDS OF THE MONTH ENJOYING LATE SUMMER`S WARMTH...WHILE THE LAST
THIRD OF THE MONTH TURNED COOL. MUCH OF OCTOBER WAS RAINY...AND SOME
GRAUPEL SHOWERS FELL SOUTH OF LAKE ONTARIO IN THE LATER COOL DAYS OF
THE MONTH.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 53.3F DEGREES WHICH IS
ABOUT TWO AND A HALF DEGREES ABOVE NORMAL. THE FIRST THREE WEEKS
WERE WARM WITH SEVEN DAYS TOPPING THE 70F MARK. FOLLOWING A WARM
FRONT THE 83F DEGREE READING ON THE 6TH WAS THE WARMEST DAY OF THE
MONTH. AS THE MONTH TURNED COOLER...EIGHT OF THE FINAL 10 DAYS
FINISHED BELOW NORMAL.

OCTOBER WAS A WET MONTH. PRECIPITATION WAS EVENLY SPREAD THROUGH THE
MONTH...AND ALTHOUGH THERE WERE NO DAILY RECORDS OR HEAVY DELUGES...
THE MONTHLY TOTAL ON 18 DAYS OF MEASURABLE RAINFALL FINISHED AT 3.32
INCHES. THIS MONTHLY TOTAL IS JUST OVER ONE HALF AN INCH ABOVE THE
NORM. THERE WERE ONLY TWO DAYS WITH THUNDER AND WHILE NO GRAUPEL
FELL AT THE AIRPORT...THERE WERE A FEW GRAUPEL SHOWERS AROUND THE
ROCHESTER METRO AREA.

OCTOBER`S TEMPERATURES PICKED UP WHERE SEPTEMBER FINISHED...WITH
WARM AFTERNOONS IN THE 70S. A STRONG COLD FRONT CROSSED THE REGION
ON MONDAY THE 7TH WITH RAIN...AND WITH THE ONSET OF COOLER AIR ALOFT
SOME LAKE EFFECT RAIN SHOWERS TO THE EAST OF ROCHESTER. HOWEVER THIS
COOL SHOT OF AIR WAS BRIEF AS WARMER AIR QUICKLY RETURNED. THIS
WARMER AIR MADE FOR A PLEASANT STRETCH DURING THE SECOND WEEK OF
OCTOBER WITH FIVE STRAIGHT DAYS OF SUNSHINE. A SERIES OF COLD FRONTS
BROUGHT MORE RAIN STARTING ON THE 13TH WITH SOME LAKE EFFECT RAIN ON
THE 17TH AND 18TH. A PATTERN CHANGED BROUGHT COOLER THAN NORMAL
CONDITIONS FOR THE FOURTH WEEK OF THE MONTH. CLEAR SKIES AND LIGHT
WINDS BROUGHT THE FIRST WIDESPREAD FREEZE TO WESTERN NEW YORK ON THE
MORNING OF THE 28TH...ABOUT A WEEK LATER THAN NORMAL. ON THE
31ST...A WARM FRONT LIFTED ACROSS THE REGION AND BROUGHT PERIODS OF
RAIN AND TEMPERATURES IN THE UPPER 60S.

THE TOTAL MONTHLY SUNSHINE FINISHED TWO PERCENT ABOVE NORMAL...WITH
ELEVEN DAYS SEEING MOSTLY SUNNY SKIES. WINDS WERE TAME THROUGH THE
MONTH AND THE STRONGEST WIND GUST ONLY TOPPED 41 MPH ON THE 22ND AND
26TH.

IN ALL A WET OCTOBER...THOUGH MANY MILD DAYS HELP TO BALANCE THE
UNSETTLED WEATHER.
