...MILD AND UNSETTLED OCTOBER...

AUTUMN WAS TRUE TO FORM THIS OCTOBER AS THE WARMTH OF LATE SUMMER
GAVE WAY TO THE FIRST CHILLS OF THE EARLY WINTER SEASON. OVERALL THE
TEMPERATURE FAIRED JUST ABOVE NORMAL...HOWEVER THE LACK OF ANY
EXTREME COLD THROUGH THE FIRST HALF OF THE MONTH DELAYED THE ONSET
OF FALL FOLIAGE AND KILLING WIDESPREAD FROST FOR AREA GARDENS.

THE TEMPERATURE THIS MONTH AVERAGED 51.0F DEGREES WHICH WAS 0.4F
ABOVE NORMAL. FOLLOWING A VERY WARM SEPTEMBER...MILD AIRMASSES
REMAINED ACROSS THE GREAT LAKES REGION THROUGH THE FIRST HALF OF THE
MONTH. IT WAS NOT UNTIL THE 15TH THAT THE AIR TEMPERATURE DIPPED
INTO THE 30S FOR THE FIRST TIME THIS SEASON...WHICH IS THE 3RD
LATEST RECORDING IN 145 YEARS WORTH OF RECORD. THE MAXIMUM
TEMPERATURE OF 45 DEGREES ON THE 17TH TIED FOR THE COOLEST MAXIMUM
TEMPERATURE FOR THE DATE.

PRECIPITATION FOR THE MONTH FINISHED AT 2.78 INCHES WHICH IS A SHADE
ABOVE NORMAL. ROUGHLY A THIRD OF THIS TOTAL FELL WITHIN ONE EVENT
WHEN THE REMNANTS OF HURRICANE PATRICIA PASSED ACROSS THE REGION. ON
OCTOBER 28TH TO 29TH EXACTLY 1.00 INCH OF RAIN FELL AT THE AIRPORT.
THERE WERE SEVERAL THUNDERSTORMS THIS MONTH...WITH 6 SUCH DAYS
RECORDING THUNDER...WHICH IS 5 MORE THAN NORMAL. THE FIRST
SNOWFLAKES OF THE SEASON WERE RECORDED THIS MONTH WITH A TRACE OF
SNOW FALLING ON BOTH THE 17TH AND 18TH OF THE MONTH.

OCTOBER STARTED COOL...BUT SUNNY WITH HIGH PRESSURE CENTERED OVER
THE REGION. HIGH PRESSURE THEN GENERALLY REMAINED OVER THE REGION
THROUGH MID MONTH...WITH BRIEF INTERRUPTIONS IN THE FAIR WEATHER BY
SEVERAL SHORTWAVES THAT PUSHED COLD FRONTS ACROSS THE REGION. THE
GREATEST RAINFALL WITH THESE FRONTS OCCURRED ON OCTOBER 8TH AND
9TH...WHEN NEARLY AN INCH OF RAIN FELL ACROSS THE ROCHESTER METRO
AREA. THE FIRST CRISP AIRMASS OF THE SEASON DROPPED ACROSS THE
EASTERN GREAT LAKES THE THIRD WEEKEND OF THE MONTH (16TH-18TH). THIS
AIRMASS BROUGHT LAKE EFFECT SNOW SOUTHEAST OF THE LAKES...WITH OVER
HALF A FOOT OF SNOW FALLING SOUTHEAST OF LAKE ONTARIO. WITH
TEMPERATURES DROPPING DOWN TOWARDS THE FREEZING MARK ON SUNDAY THE
18TH THE GROWING SEASON OFFICIALLY ENDED FOR ALL OF THE REGION.
SERENE AUTUMN WEATHER RETURNED WITH AIR TEMPERATURES QUICKLY
REBOUNDING BACK INTO THE UPPER 60S BY THE 20TH FOLLOWING THE FIRST
SNOW OF THE SEASON. THE REMNANTS OF HURRICANE PATRICIA REACHED
WESTERN NEW YORK IN THE EARLY MORNING HOURS OF THE 28TH. THIS SYSTEM
BROUGHT A SOAKING RAIN WEDNESDAY THE 28TH ALONG WITH GUSTY WIND
GUSTS ON BOTH THE 28TH AND THE 29TH. ON THE 29TH WINDS REACHED 43
MPH AT THE AIRPORT. THE MONTH ENDED COOLER AND QUIETER...WITH RAIN
SHOWERS HOLDING OFF UNTIL MOST OF HALLOWEEN FESTIVITIES WERE
COMPLETED.

WINDS AVERAGED ABOVE NORMAL THIS MONTH...WITH THE AVERAGE SPEED OF
9.4 MPH AN EVEN 1.0 MPH GREATER THAN NORMAL. THE STRONGEST WIND GUST
OCCURRED ON THE 15TH WHEN WESTERLY WIND GUSTS REACHED 53 MPH.

OVERALL A PLEASANT OCTOBER WITH BRIEF INTERRUPTIONS OF COLDER AND
WINDIER CONDITIONS.
