...SEPTEMBER 2013 SAW A WIDE RANGE IN TEMPERATURES AND NEAR NORMAL
PRECIPITATION...

SEPTEMBER 2013 WILL GO DOWN IN THE RECORD BOOKS AS A MONTH WITH
FREQUENT SWINGS IN TEMPERATURES...FEATURING A COUPLE OF DAYS WITH
MID SUMMER-LIKE HEAT AND HUMIDITY FOLLOWED BY A CHANGE TO MORE
FALL-LIKE CONDITIONS WHEN TEMPERATURES GOT COLD ENOUGH FOR FROST
ACROSS MANY INLAND LOCATIONS. THUS...WHILE THE MONTHLY AVERAGE
TEMPERATURE OF 61.4 DEGREES WAS JUST 0.8 DEGREES BELOW THE
CLIMATOLOGICAL AVERAGE...THE DAILY TEMPERATURES SHOWED A LOT OF
VARIABILITY.

THE MONTHLY RAINFALL WAS 3.53 INCHES WHICH IS 0.37 INCH BELOW
AVERAGE. MEASURABLE PRECIPITATION THAT FELL ON TEN DAYS WAS MAINLY
LIGHT...WITH MOST DAYS SEEING LESS THAN ONE QUARTER INCH OF RAIN.
THE EXCEPTION TO THIS TREND OCCURRED ON THE 21ST WHEN A SLOW MOVING
COLD FRONT BROUGHT RECORD SETTING RAINFALL TO BUFFALO AND PARTS OF
THE SOUTHERN TIER CLOSE TO LAKE ERIE.

THE RELATIVELY DRY CONDITIONS THAT PREVAILED FOR MUCH OF THE MONTH
RESULTED IN A FAIR AMOUNT OF SUNSHINE WHICH ENDED UP AT 68 PERCENT
OF THE TOTAL POSSIBLE.

THE LAKE ERIE WATER TEMPERATURE STARTED OUT AT 74 DEGREES AND COOLED
TO 66 DEGREES BY THE END OF THE MONTH. THIS IS SLIGHTLY WARMER THAN
THE AVERAGE TEMPERATURE TREND FOR SEPTEMBER.

OVERALL...SEPTEMBER WAS A PLEASANT START TO FALL.
