...A QUIET END TO SUMMER ACROSS WESTERN NEW YORK...

A SEEMINGLY COOL MONTH OF AUGUST HAS FINISHED NEAR NORMAL AS A LATE
MONTH SURGE OF SUMMERS WARMTH AND HUMIDITY DURING THE LAST WEEK OF
THE MONTH BROUGHT TEMPERATURES BACK CLOSER TO NORMAL. THERE WERE NO
90 DEGREE DAYS THIS MONTH. AN ABUNDANCE OF SUNSHINE IN AUGUST MADE
FOR A FINE END TO THE SUMMER.

THE AVERAGE TEMPERATURE OF 68.2F WAS JUST OVER A DEGREE BELOW
NORMAL. THE COOLEST DAY THIS MONTH WAS A MERE 67F DEGREES...WHICH WAS
THE COOLEST MAXIMUM TEMPERATURE FOR AUGUST SINCE 2009 WHEN THERE WAS
ALSO A 67F DEGREE READING. THE WARMEST TEMPERATURE OCCURRED DURING
THE LAST WEEK OF THE MONTH WHEN ON BOTH THE 26TH AND 30TH THE
AFTERNOON TEMPERATURE ROSE TO 87F DEGREES. THERE WERE NO TEMPERATURE
RECORDS THIS MONTH.

PRECIPITATION THIS MONTH WAS ABOUT AN INCH AND A QUARTER BELOW
NORMAL...WHICH WAS WELCOMED AFTER A VERY WET JULY. MUCH OF THE RAIN
CAME IN THUNDERSTORM DELUGES. A STORM ON THE 12TH BROUGHT NEARLY AN
INCH OF RAINFALL. THERE WERE 10 DAYS WITH MEASURABLE RAINFALL WHICH
IS AVERAGE.

THE FIRST WEEK OF THE MONTH OF AUGUST STARTED WET AND COOL. FLASH
FLOODING OCCURRED ON THE 2ND JUST TO THE SOUTH OF THE METRO AREA
WHERE THUNDERSTORMS PRODUCED A TORRID OF RAINFALL. A WARM FRONT
LIFTED NORTHWARD ACROSS WESTERN NEW YORK THE SECOND WEEK OF THE
MONTH AND BROUGHT A BRIEF STRETCH OF SUMMER LIKE WEATHER WITH
TEMPERATURES IN THE 80S AND A TOUCH OF HUMIDITY. THIS WARMTH WAS
SHORT LIVED AS A COLD FRONT EASED ACROSS WESTERN NEW YORK ON THE
13TH...FOLLOWED BY A VERY COOL DAY ON THE 14TH. THIS COOL AIRMASS
BROUGHT LAKE EFFECT RAIN OFF LAKE ERIE AND ACROSS PORTIONS OF
WESTERN NEW YORK ON THE 14TH AND 15TH. THE LONGEST STRETCH OF DRY
WEATHER THIS SUMMER STARTED ON SUNDAY THE 17TH. HIGH PRESSURE AND
DRY FRONTAL PASSAGES ALLOWED THE REGION TO REMAIN DRY THROUGH
SATURDAY THE 30TH. ONLY A FEW HUNDREDTHS FROM A PASSING SHOWER ON THE
27TH INTERRUPTED THIS STREAK. SUMMERS WARMTH RETURNED THE LAST WEEK
OF THE MONTH. A FEW THUNDERSTORMS ON THE 30TH AND 31ST BROUGHT AN
END TO THE DRY STRETCH...ONE THAT GAVE A BROWN TINT TO LOCAL LAWNS.

WINDS FOR THE MONTH WERE GENERALLY LIGHT AND WITH THE LIGHT SYNOPTIC
FLOW THIS MONTH STRONG WIND GUSTS WERE LACKING FROM THUNDERSTORMS.

IN ALL A FINE END TO SUMMER ACROSS WESTERN NEW YORK.


METEOROLOGICAL SUMMER (JUNE...JULY...AUGUST) RECAP...


THE ROCHESTER METRO AREA ENJOYED A FINE...ALBEIT SLIGHTLY WETTER THAN
NORMAL SUMMER. THE SUMMER AVERAGE TEMPERATURE OF 68.8F DEGREES WAS
EXACTLY NORMAL. ALL THREE MONTHS AVERAGE TEMPERATURES WERE SIMILAR
WITH ABOUT A DEGREE SEPARATING THE WARMEST MONTH (JULY) FROM THE
COOLEST MONTH (AUGUST). THERE WERE ONLY TWO 90F+ DEGREE READINGS
THIS SUMMER WHICH IS 6 DAYS LESS THAN NORMAL AND FEWEST SINCE 2009.

THE OVERALL SYNOPTIC FLOW WAS LIGHT THIS SUMMER WITH PASSAGES OF
COOL UPPER LEVEL TROUGHS. SEVERE THUNDERSTORMS WERE LESS THAN
AVERAGE THIS SUMMER...WHILE THE OCCURRENCES OF FLASH FLOODING FROM
SLOW MOVING STORMS WAS ABOVE NORMAL. MANY AREAS ACROSS WESTERN NEW
YORK RECEIVED SUMMER`S DELUGE OF RAINFALL THAT BROUGHT FLASH
FLOODING AND WASHED OUT LOCAL ROADS AND BRIDGES. FOR THE ROCHESTER
AIRPORT THE TOTAL SUMMER RAINFALL WAS 12.03 INCHES WHICH IS ALMOST
TWO INCHES ABOVE NORMAL. THERE WERE 6 DAYS WITH A HALF INCH OR
GREATER RAINFALL...WHICH IS NORMAL FOR THE SUMMER. THIS RAINFALL
MAINTAINED GREEN LAWNS THROUGH MUCH OF THE SUMMER...THOUGH SOME
VEGETATION IN GARDENS SUFFERED FROM TOO MUCH RAINFALL AND DAMPNESS.

STATS...


               AVERAGE  (NORMAL)


TEMPERATURE......68.8F   (0.0)

RAINFALL.........12.41" (+2.26")
