... ABSOLUTELY GORGEOUS SEPTEMBER ...

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 64.7F THIS MONTH, WHICH IS AROUND A DEGREE
ABOVE NORMAL. ASIDE FROM A COOL PERIOD FROM THE 13TH TO 20TH, MUCH
OF THE MONTH FEATURED ABOVE NORMAL WARMTH. THE 22 DAYS REACHING AT
LEAST 70F IS 4 DAYS MORE THAN THE SEPTEMBER NORMAL. THE TWO DAYS
THAT REACHED INTO THE 90S (5TH AND 6TH) WERE THE FIRST SEPTEMBER 90F
DEGREE DAYS SINCE 2018, WHICH FEATURED THREE SUCH DAYS. 

PRECIPITATION TOTALED 1.37 INCHES FOR THE MONTH, WHICH IS ALMOST TWO
INCHES BELOW THE SEPTEMBER NORMAL. THE BULK OF THE PRECIPITATION
FELL IN TWO EVENTS. THE FIRST EVENT WAS LATE ON THE 6TH TO THE
MORNING HOURS OF THE 7TH, AND IN TOTAL 0.44 INCHES OF RAIN. THE
SECOND EVENT OCCURRED ON THE 18TH IN LATE MORNING THROUGH EVENING
THUNDERSTORMS AND TOTALED 0.70 INCHES 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 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. 

WITH THE SURFACE HIGH PRESSURE NEARBY, WINDS WERE GENTLE, AVERAGING
JUST 6.1 MPH, WHICH IS OVER ONE MILE PER HOUR BELOW NORMAL. THERE
WERE NO STRONG WIND GUSTS, WITH THE STRONGEST GUST BEING JUST 31 MPH
ON THE 18TH AND AGAIN THE 19TH IN WEST-NORTHWEST FLOW. 

IN ALL, A SPLENDID MONTH.
