...CONTINUED SUMMER`S WARMTH INTO SEPTEMBER...

AFTER A WARM AND DRY SUMMER, THERE WAS JUST A LITTLE REPRIEVE FROM
THE ABNORMAL WARMTH AND DRYNESS THROUGH THE MONTH OF SEPTEMBER.
THOUGH THERE WAS AN INCREASE IN RAINFALL, AND VEGETATION REGAINED
ITS LUSHNESS, PRECIPITATION REMAINED BELOW NORMAL THIS MONTH, AND
GROUND WATER REMAINED LOW.

THE AVERAGE TEMPERATURE THIS MONTH WAS 67.0F, WHICH PLACES THIS
SEPTEMBER AS 6TH WARMEST ON RECORD. THERE WERE 6 DAYS THAT PLACED
BELOW NORMAL THIS MONTH, INCLUDING THREE STRAIGHT DAYS TO START THE
MONTH. THE HIGH TEMPERATURE ON SEPTEMBER 24TH WAS ONLY 65F, ENDING A
STRING OF 102 STRAIGHT DAYS THAT REACHED 70F OR GREATER. THERE WERE
11 DAYS THIS MONTH THAT REACHED 80F OR GREATER, WHICH IS TIED FOR
FOURTH GREATEST FOR SEPTEMBER AND BROUGHT THE YEARLY TOTAL UP TO 83
DAYS...TIED AT MONTHS END WITH THE YEAR 1949 FOR GREATEST AMOUNT OF
DAYS IN A YEAR REACHING 80F OR GREATER. THERE WAS ONE RECORD WARM
MINIMUM TEMPERATURE SET, THIS OF 75F DEGREES ON THE 8TH.

PRECIPITATION THIS MONTH TOTALED 3.53 INCHES WHICH IS ABOUT A THIRD
OF AN INCH BELOW NORMAL. IT WAS A FAIRLY DRY MONTH, WITH HEAVY
RAINFALL COMING IN A FEW SHORT BURSTS. HALF OF SEPTEMBERS RAINFALL
FELL ON THE 17TH WHEN SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS
CROSSED WESTERN NEW YORK. THOUGH THIS 1.76 INCHES ON THE 17TH DID
NOT SET A DAILY RECORD IT WAS THE GREATEST RAINFALL ON A CALENDAR
DAY IN JUST OVER A YEAR. FOR THE WATER YEAR ENDING SEPTEMBER 30TH, 9
OF THE 12 MONTHS FINISHED WITH BELOW NORMAL PRECIPITATION.

THE MONTH STARTED ON THE COOL SIDE WITH COMFORTABLE AFTERNOONS IN
THE 70S, AND OVERNIGHT LOWS DROPPING DOWN INTO THE 50S. BY LABOR
DAY, THE 5TH, TEMPERATURES WERE BACK INTO THE 80S, WITH FULL
SUNSHINE. VERY WARM DAYS AND AT TIMES STICKY DEWPOINTS REMAINED OVER
THE AREA THROUGH THE 10TH. ON THE 10TH, AND ALONG A WARM FRONT AND
THEN A COLD FRONT, A SOLID HALF TO ONE INCH OF RAIN FELL ACROSS THE
WESTERN COUNTIES OF WESTERN NEW YORK. THIS COLD FRONT THEN BROUGHT
COOLER AND DRIER AIR TO THE REGION FOR MID MONTH. A WEEK LATER,
ANOTHER STORM SYSTEM BROUGHT COPIOUS AMOUNTS OF RAINFALL TO WESTERN
NEW YORK ON THE 17TH. FAIR WEATHER RETURNED AFTER THIS DELUGE OF
RAIN, WITH TEMPERATURES NEAR NORMAL THE THIRD WEEK OF THE MONTH. TO
CLOSE THE MONTH AN UPPER LEVEL LOW BROUGHT MUCH COOLER AIR, CREATING
LAKE EFFECT RAIN ON THE 26TH, AND THEN PERIODS OF LIGHT RAIN SHOWERS
THROUGH THE END OF THE MONTH.

LAKE ERIE MAINTAINED ITS RECORD WARMTH THROUGH MUCH OF THE MONTH. IN
ADDITION TO A RECORD 77F DEGREES TO START THE MONTH, A STREAK FROM
THE 9TH TO THE END OF THE MONTH SET NEW DAILY LAKE WATER WARM
TEMPERATURES. THE LAKE COOLED TO JUST 69F BY MONTHS END.

IN ALL ANOTHER AMAZING MONTH, WARM WITH JUST A FEW UNSETTLED DAYS.
