A PLEASANT AND WARM SEPTEMBER WAS ONLY INTERRUPTED BY A WEEK OF
CHILLY TEMPERATURES MID MONTH. A STRONG RIDGE OF HIGH PRESSURE ENDED
THE LAST WEEK OF THE MONTH WITH SUMMER LIKE WARMTH AND ABUNDANT
SUNSHINE.

THE AVERAGE TEMPERATURE OF 63.2F WAS A DEGREE ABOVE THE MONTHLY
NORMAL. SEPTEMBER WAS ONLY THE THIRD ABOVE NORMAL MONTH THIS YEAR
WITH MAY AND JUNE ALSO ABOVE NORMAL. THERE WERE 20 DAYS THAT REACHED
70F OR GREATER WHICH IS 3 DAYS MORE THAN NORMAL. THERE WAS ONE
RECORD TEMPERATURE SET...THE 55F DEGREE READING ON SEPTEMBER 12TH
WAS THE LOWEST MAXIMUM TEMPERATURE FOR THAT DATE...AND COLDEST
MAXIMUM IN SEPTEMBER SINCE 2009.

SEPTEMBER WAS A BIT BELOW NORMAL FOR RAINFALL AS ONLY 3.13 INCHES OF
RAIN FELL. THIS IS ABOUT THREE QUARTERS OF AN INCH BELOW
NORMAL...THOUGH DAYS OF MEASURABLE RAINFALL WERE EXACTLY NORMAL...AT
11 DAYS. A THIRD OF THIS RAINFALL FELL THE FIRST WEEKEND OF THE
MONTH WHEN A STRONG COLD FRONT BROUGHT 1.45 INCHES OF RAIN TO THE
BUFFALO AIRPORT LATE FRIDAY NIGHT AND SATURDAY MORNING. THERE WERE
THREE DAYS OF THUNDER.

SEPTEMBER BEGAN WITH SUMMERS WARMTH AND TEMPERATURES IN THE UPPER
70S AND LOWER 80S. A COLD FRONT SWEPT ACROSS THE REGION WITH SHOWERS
AND THUNDERSTORMS ON THE 2ND. AHEAD OF THIS COLD FRONT A LINE
SEGMENT OF THUNDERSTORMS BROUGHT DOWN TREES WELL TO THE SOUTH OF
BUFFALO ACROSS CATTARAUGUS COUNTY. THERE WAS LITTLE COLD AIR BEHIND
THIS FRONT AND IN FACT TEMPERATURES ON THE 3RD WERE WARMER. THE
WARMEST AIRMASS OF THE MONTH THEN PASSED ACROSS WESTERN NEW YORK ON
THE 4TH AND 5TH WITH TEMPERATURES REACHING INTO THE MID 80S. THIS
WARMTH WAS ERASED BY A COLD FRONT ON FRIDAY THE 5TH. WHILE IT
REMAINED DRY THROUGH THE DAY HEAVY SHOWERS AND THUNDERSTORMS REACHED
BUFFALO BY LATE EVENING WITH DOWNPOURS DROPPING MORE THAN AN INCH OF
RAINFALL ACROSS MUCH OF WESTERN NEW YORK. THE RAINFALL ENDED DURING
THE MORNING HOURS OF THE 6TH WITH DRY AND COMFORTABLE WEATHER
RETURNING THAT AFTERNOON. AFTERNOONS IN THE 70S REMAINED ACROSS THE
REGION UNTIL THE 12TH...WHEN FOLLOWING A STRONG COLD FRONT HIGHS
ONLY REACHED THE MID 50S. THIS GAVE THE FIRST FALLISH FEEL TO
THE AIR AND MADE THE 12TH THE COOLEST DAY THIS MONTH. FOR THE NEXT
WEEK AUTUMN WAS THE TONE AS AFTERNOON HIGHS REACHED ONLY INTO THE
60S. ANOTHER UPPER LEVEL DISTURBANCE BROUGHT A RAINY DAY TO THE
REGION ON THE 15TH.

TEMPERATURES REBOUNDED BACK INTO THE 70S BY THE 20TH THOUGH ANOTHER
COLD FRONT BROUGHT SOME SHOWERS TO THE AREA ON THE 21ST AND MADE FOR
A CHILLY DAY ON THE 22ND. BY WEDNESDAY THE 24TH A DOMINATING AREA OF
HIGH PRESSURE SETTLED ACROSS THE GREAT LAKES REGION. THIS FEATURE
BROUGHT MOSTLY SUNNY SKIES AND TEMPERATURES WARMING BACK TOWARDS 80F
BY MONTHS END. ONLY THE FINAL DAY OF THE MONTH FEATURED CLOUDY SKIES
WITH SCATTERED RAIN SHOWERS.

LAKE ERIE SLOWLY COOLED THROUGH THE MONTH DROPPING FROM 73F EARLY IN
THE MONTH DOWN TO 66F BY MONTHS END. WINDS AVERAGED 8 MPH THROUGH
THE MONTH.

IN ALL A NICE START TO THE AUTUMN SEASON ACROSS WESTERN NEW YORK.
