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 62.9F WAS JUST OVER 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 21 DAYS THAT
REACHED 70F OR GREATER WHICH IS 3 DAYS MORE THAN NORMAL. THERE WAS
ALSO ONE 90 DEGREE DAY...WHICH OCCURRED ON THE 5TH. THIS WAS ONLY
THE 3RD SUCH DAY THIS SUMMER SEASON WHICH IS 6 DAYS BELOW NORMAL.
THE COOLEST DAY THIS MONTH WAS ON THE 22ND WHEN THE HIGH REACHED
ONLY 57 DEGREES.

SEPTEMBER WAS A DRY MONTH WITH ONLY 1.33 INCHES OF RAINFALL. THIS
WAS THE DRIEST MONTH SINCE 1964. THOUGH THERE WERE EXACTLY NORMAL
AMOUNT OF DAYS WITH MEASURABLE RAINFALL...ALL EVENTS WERE A THIRD OF
AN INCH OR LESS. THE LAST SEPTEMBER THAT THIS OCCURRED WAS ALSO BACK
IN 1964. THERE WERE THREE DAYS OF THUNDER.

SEPTEMBER BEGAN WITH SUMMERS WARMTH AND TEMPERATURES IN THE 80S. A
COLD FRONT SWEPT ACROSS THE REGION WITH SHOWERS AND THUNDERSTORMS ON
THE 2ND. THERE WAS LITTLE COLD AIR BEHIND THIS FRONT AND
TEMPERATURES ON THE 3RD STILL MANAGED TO CLIMB INTO THE LOWER 80S.
THE WARMEST AIRMASS OF THE MONTH THEN PASSED ACROSS WESTERN NEW YORK
ON THE 4TH AND 5TH WITH TEMPERATURES REACHING INTO THE MID 80S TO
LOWER 90S. THIS WARMTH WAS ERASED BY A COLD FRONT ON FRIDAY THE 5TH.
WHILE IT REMAINED DRY A FEW SHOWERS FELL OVERNIGHT AND EARLY
SATURDAY MORNING THE 6TH. AFTERNOONS IN THE 70S REMAINED ACROSS THE
REGION UNTIL THE 12TH...WHEN FOLLOWING A STRONG COLD FRONT HIGHS
ONLY REACHED 60F. THIS GAVE THE FIRST FALLISH FEEL TO THE AIR. FOR
THE NEXT WEEK AUTUMN WAS THE TONE AS AFTERNOON HIGHS REACHED ONLY
INTO THE 60S. ANOTHER UPPER LEVEL DISTURBANCE BROUGHT A COUPLE OF
RAINY DAYS TO THE REGION ON THE 15TH AND 16TH.

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.

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