FABULOUS START, THEN WET AND MURKY OCTOBER

GLORIOUS WEATHER OF SEPTEMBER CONTINUED INTO THE EARLY DAYS OF
OCTOBER WITH PLEASANT WEATHER CONDITIONS. COLDER AIR IMPINGED UPON
WESTERN NEW YORK BY THE END OF THE FIRST WEEK, WITH SHOWERS AND
EVENTUALLY LAKE EFFECT RAIN BANDS. THIS 10-DAY COLD SPELL WAS
OUTWEIGHED BY A MILD START AND END TO THE MONTH TO ALLOW FOR THE
AVERAGE TEMPERATURE FOR OCTOBER TO BE SEVERAL DEGREES ABOVE NORMAL
AND TIED FOR 18TH WARMEST ON RECORD. MANY DAYS HAD LIGHT
PRECIPITATION, WITH THE RAINFALL SPREAD THROUGHOUT THE MONTH. THE
WETTEST DAY THE 10TH FEATURED BANDS OF LAKE EFFECT RAIN.  

THE TEMPERATURE AVERAGED 54.9°F THIS MONTH, RANKING T-18TH WARMEST
ON RECORD. OF THE 14 DAYS AVERAGING ABOVE THE DAILY NORMAL, 9 DAYS
WERE BY AT LEAST 10 DEGREES. WHILE THE MAXIMUM TEMPERATURE WAS JUST
1.6F DEGREES ABOVE NORMAL, THE MINIMUM TEMPERATURE WAS 4.7 DEGREES
ABOVE NORMAL. DAYS REMAINING 40°F OR GREATER TOTALED 27, TIED FOR
9TH GREATEST ON RECORD. THERE WAS ALSO ONE RECORD WARM MINIMUM
TEMPERATURE ESTABLISHED. THE 63F MINIMUM ON THE 27TH BROKE THE
FORMER RECORD OF 58F ESTABLISHED BACK IN 1984. 

PRECIPITATION TOTALED 3.74 INCHES WHICH IS ABOUT A QUARTER OF AN
INCH BELOW NORMAL. HOWEVER, THE NUMBER OF DAYS WITH MEASURABLE RAIN
TOTALED 21, TIED WITH 2012 FOR SECOND GREATEST ON RECORD. ONLY THE
YEAR 1890 HAD MORE, AND THIS WAS 25 DAYS. THE DRIEST PERIOD WAS THE
FIRST 4 DAYS OF THE MONTH WHICH FEATURED NO RAINFALL. LATE ON THE
31ST THE FIRST MEASURABLE SNOW FELL AT THE AIRPORT, WITH LARGE
FLAKES ADDING UP TO 0.4 INCHES.  

ON THE HEELS OF A GLORIOUS SEPTEMBER, THE FIRST 5 DAYS OF OCTOBER
DID NOT DISAPPOINT WITH AUTUMN`S FINEST WEATHER ON DISPLAY. NOT
UNTIL VERY LATE ON THE 5TH AND INTO THE 6TH DID RAIN SHOWERS ENTER
WESTERN NEW YORK. A MUCH COLDER AIRMASS MAINTAINED SHOWERS ACROSS
WESTERN NEW YORK WITH LAKE EFFECT RAIN ON THE 9TH AND 10TH SOAKING
METRO BUFFALO WITH OVER AN INCH OF RAINFALL. COOL AIR CONTINUED
THROUGH MID-MONTH. CLEARING SKIES ON THE MORNING OF THE 13TH ALLOWED
FOR PATCHES OF FROST AROUND THE METRO AREA. ANOTHER SURGE OF MUCH
WARMER AIR SURGED INTO WESTERN NEW YORK FOR THE 24TH THROUGH THE
28TH. DAYS IN THE 70S WERE COUPLED WITH A FEW RAIN SHOWERS THAT
GENERALLY FELL LATE EVENING AND OVERNIGHT. A COLD FRONT SWEPT
THROUGH BUFFALO ON THE 29TH WITH COLD AIR AGAIN RETURNING TO THE
REGION. RAIN SHOWERS, AND EVENTUALLY LAKE EFFECT RAIN FELL THE FINAL
DAYS OF THE MONTH. THE FIRST MEASURABLE SNOW OCCURRED LATE ON THE
31ST, THIS AFTER A DISMAL EARLY EVENING OF TRICK-OR-TREATING. 

LAKE ERIE STARTED THE MONTH WITH RECORD WARM WATERS, REACHING 71F
FOR THE FIRST TIME IN OCTOBER ON THE 4TH THROUGH THE 6TH. COOLER AIR
MID-MONTH ALLOWED FOR THE WATER TEMPERATURE  TO COOL QUICKLY BACK
DOWN INTO THE LOWER 60S, FINISHING THE MONTH AT 57F ON THE 31ST.
WINDS WERE SLIGHTLY BELOW NORMAL, BY ABOUT A HALF A MILE PER HOUR.
THERE WERE SEVERAL DAYS THAT HAD WIND GUSTS OVER 40 MPH, THESE ON
THE 8TH AND 9TH OF THE MONTH.  

IN ALL, A CLOUDY AND WET MONTH.
