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. && THOMAS $$
