THERE WAS LITTLE WEATHER OF NOTE THIS MONTH, ESPECIALLY THE FINAL HALF OF THE MONTH WHICH FEATURED MOST DAYS SUNNY AND MILD. MOST OF THE RAINFALL WAS CONVECTIVE AND AT NIGHT LEAVING MUCH OF THE MONTH ENJOYABLE. THE TEMPERATURE AVERAGED 65.3F THIS MONTH, WHICH IS 2 DEGREES ABOVE NORMAL. ASIDE FROM A COOL PERIOD FROM THE 13TH TO 20TH, MUCH OF THE MONTH FEATURED ABOVE NORMAL WARMTH. THERE WERE 25 DAYS THAT REACHED INTO THE 70S, TIED FOR 5TH GREATEST FOR SEPTEMBER. GREATEST NUMBER OF DAYS IN THE 70S OCCURRED IN THE YEAR 1881, WITH ALL BUT ONE DAY REACHING AT LEAST 70F. THERE WAS ONE RECORD WARM MINIMUM TEMPERATURE ESTABLISHED, THIS BEING THE LOW TEMPERATURE OF 73F ON THE 4TH TYING WITH 1985 FOR WARMEST MINIMUM TEMPERATURE FOR THE DATE. PRECIPITATION TOTALED 2.67 INCHES FOR THE MONTH, WHICH IS ALMOST AN INCH AND A HALF BELOW SEPTEMBER NORMAL. THE BULK OF THE PRECIPITATION FELL IN ONE EVENT, THIS LATE ON THE 6TH TO THE EARLY MORNING HOURS OF THE 7TH, AND IN TOTAL 1.81 INCHES OF RAIN FELL IN THIS EVENT. A QUICK AFTERNOON THUNDERSTORM ON THE 12TH DROPPED ANOTHER HALF INCH OF RAIN AT THE BUFFALO AIRPORT, AND AN AFTERNOON THUNDERSTORM ON THE 18TH DROPPED A QUARTER OF AN INCH OF RAIN. FOR THE MONTH, ANOMALOUS STRONG HIGH PRESSURE ANCHORED NEAR JAMES BAY PROVIDED PLENTY OF GORGEOUS DAYS, KEEPING HUMIDITY AT BAY, AND DELIVERING A WEALTH OF SUNSHINE TO THE EASTERN GREAT LAKES REGION. THERE WERE A FEW VERY WARM AND HUMID DAYS THE FIRST WEEK OF THE MONTH, WHICH MADE FOR SOME UNCOMFORTABLE SLEEPING CONDITIONS, BUT OTHERWISE DRY AUTUMN DAYS WERE PLENTY. THUNDERSTORMS WERE NON SEVERE AND GENERALLY WERE BRIEF, OR OCCURRING AT NIGHT. THE WATER TEMPERATURE ON LAKE ERIE FLUCTUATED BETWEEN 68 AND 73 DEGREES FOR THE MONTH. WITH THE SURFACE HIGH PRESSURE NEARBY, WINDS WERE GENTLE, AVERAGING JUST 7.5 MPH, WHICH IS JUST OVER A MILE PER HOUR BELOW NORMAL. THERE WERE NO STRONG WIND GUSTS, WITH THE STRONGEST GUST BEING JUST 35 MPH ON THE 12TH DURING A THUNDERSTORM. IN ALL, A SPLENDID MONTH. && THOMAS $$
