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 12-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 RANKED 13TH WARMEST ON RECORD. MANY DAYS HAD LIGHT
PRECIPITATION, WITH THE RAINFALL SPREAD THROUGHOUT THE MONTH. 

THE TEMPERATURE AVERAGED 55.5°F THIS MONTH, RANKING 13TH WARMEST ON
RECORD. OF THE 14 DAYS AVERAGING ABOVE THE DAILY NORMAL, 8 DAYS WERE
BY AT LEAST 10 DEGREES. WHILE THE MAXIMUM TEMPERATURE WAS 2.5
DEGREES ABOVE NORMAL, THE MINIMUM TEMPERATURE WAS 4.0 DEGREES ABOVE
NORMAL. DAYS REMAINING 40°F OR GREATER TOTALED 26, TIED FOR 7TH
GREATEST ON RECORD. RECORD IS 28 DAYS SET IN 1938. THERE WAS ALSO
ONE RECORD WARM MINIMUM TEMPERATURE ESTABLISHED. THE 61F MINIMUM ON
THE 27TH BROKE THE FORMER RECORD OF 56F ESTABLISHED BACK IN 1920. 

PRECIPITATION TOTALED 1.83 INCHES WHICH IS MORE THAN AN INCH AND A
THIRD BELOW NORMAL. HOWEVER, THE NUMBER OF DAYS WITH MEASURABLE RAIN
TOTALED 17, TIED FOR 9TH GREATEST FOR OCTOBER. THE YEAR 1988 HAD THE
GREATEST NUMBER OF DAYS WITH MEASURABLE RAINFALL, THIS AT 21 DAYS.
THE DRIEST PERIOD WAS THE FIRST 5 DAYS OF THE MONTH WHICH FEATURED
NO RAINFALL. LATE ON THE 31ST THE FIRST MEASURABLE SNOW FELL AT THE
AIRPORT, WITH 0.2 INCHES MEASURED.  

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 EARLY ON THE 6TH DID RAIN SHOWERS ENTER THE GENESEE VALLEY. A
MUCH COLDER AIRMASS MAINTAINED SHOWERS ACROSS WESTERN NEW YORK WITH
LAKE EFFECT RAIN ON THE 9TH AND 10TH OCCASIONALLY WETTING THE GROUND
AT THE ROCHESTER AIRPORT.  COOL AIR CONTINUED THROUGH MID-MONTH.
CLEARING SKIES ON THE MORNING OF THE 13TH ALLOWED FOR PATCHES OF
FROST AROUND THE ROCHESTER METRO AREA. ANOTHER SURGE OF MUCH WARMER
AIR ENTERED 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
ROCHESTER 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 OF THE SEASON OCCURRED LATE ON
THE 31ST, THIS AFTER A DISMAL EARLY EVENING OF TRICK-OR-TREATING. 

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.
