...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 51.4F DEGREES WHICH WAS 0.6F
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 LATE HOURS OF THE 16TH THAT THE AIR
TEMPERATURE DIPPED INTO THE 30S FOR THE FIRST TIME THIS
SEASON...WHICH IS THE 4TH LATEST RECORDING SINCE RECORDS MOVED TO
THE AIRPORT IN 1943. THERE WERE NO EXTREME TEMPERATURES OR RECORDS
ESTABLISHED THIS MONTH.

PRECIPITATION FOR THE MONTH FINISHED ABOVE NORMAL...WITH 3.81 INCHES
MEASURED. ROUGHLY HALF OF THIS TOTAL FELL WITHIN ONE EVENT WHEN THE
REMNANTS OF HURRICANE PATRICIA PASSED ACROSS THE REGION. ON OCTOBER
28TH TO 29TH 1.83 INCHES OF RAIN FELL AT THE AIRPORT...INCLUDING A
DAILY RECORD 1.64 INCHES ON THE 28TH. THERE WERE SEVERAL
THUNDERSTORMS THIS MONTH...WITH 5 SUCH DAYS RECORDING THUNDER. NOT
UNUSUAL WERE THAT 3 OF THESE DAYS WITH THUNDERSTORMS RECORDED THE
THUNDER TOWARDS THE LATE MIDNIGHT HOUR. THE FIRST SNOWFLAKES OF THE
SEASON WERE RECORDED THIS MONTH WITH A TRACE OF SNOW FALLING ON BOTH
THE 17TH AND 18TH.

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 A GENERAL INCH OF RAIN FELL ACROSS THE BUFFALO 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
SEVERAL INCHES OF SNOW FALLING ACROSS THE HILLS SOUTH OF
BUFFALO...AND A TRACE OF SNOW AT THE AIRPORT. 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 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 ON WEDNESDAY THE 28TH ALONG WITH DAMAGING WIND GUSTS ON
BOTH THE 28TH AND THE 29TH. ON THE 28TH SOUTHEAST WINDS GUSTED TO 46
MPH AT THE AIRPORT...WHILE STRONGER WINDS SWEPT DOWN THE CHAUTAUQUA
RIDGE WHERE A GUST TO 62 MPH WAS RECORDED AT THE DUNKIRK AIRPORT.
AS A COLD FRONT CROSSED THE REGION EARLY THURSDAY THE 29TH WINDS
SHIFTED TO SOUTHWEST AND INCREASED TO 61 MPH ALONG THE LAKE ERIE
SHORELINE. THE MONTH ENDED COOLER AND QUIETER...WITH RAIN SHOWERS
HOLDING OFF UNTIL MOST OF HALLOWEEN FESTIVITIES WERE COMPLETED.

WINDS AVERAGED 1.1 MPH ABOVE NORMAL THIS MONTH...WITH AN AVERAGE
SPEED OF 10.8 MPH. THE STRONGEST WIND GUST OCCURRED ON THE 29TH WHEN
SOUTHWEST WINDS REACHED 61 MPH AT THE AIRPORT JUST PAST SUNRISE.
THESE STRONG SOUTHWEST WINDS ALSO PRODUCED A SEICHE ON LAKE ERIE
WITH THE LAKE RISING TO 82 INCHES ABOVE LOW WATER DATUM THURSDAY
MORNING. THE LAKE TEMPERATURE ON LAKE ERIE DROPPED FROM 66 DEGREES
AT MONTHS START TO 53 DEGREES BY THE END OF THE MONTH.

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