DRY, COOL END TO SUMMER
AREAS OF HIGH PRESSURE, ESPECIALLY THE SECOND HALF OF THE MONTH,
MAINTAIN QUIET WEATHER THROUGH AUGUST WHICH PROLONGED THE EXPANDING
AREA OF MODERATE DROUGHT CONDITIONS ACROSS WESTERN NEW YORK. A COOL
SECOND HALF OF AUGUST BROUGHT THE MONTHLY TEMPERATURE TO BELOW
NORMAL FOR THE MONTH. EXCEPT FOR A BRIEF PERIOD OF HEAT THE SECOND
WEEK OF THE MONTH, THE LOW HUMIDITY COMBINED WITH THE EXTENDED
PERIODS OF DRY WEATHER MADE FOR EXCELLENT OUTDOOR WEATHER FOR EVENTS
THROUGHOUT THE MONTH.
THE TEMPERATURE AVERAGED 68.7F THIS MONTH WHICH IS TWO DEGREES
BELOW NORMAL. THERE WERE THREE CONSECUTIVE DAYS IN THE 90S, THIS
OCCURRING ON THE 10TH THROUGH THE 12TH, WITH ALL THREE DAYS REACHING
92F. BEHIND A STRONG COLD FRONT THE TEMPERATURE DROPPED TO 43F THE
MORNING OF THE 30TH, AND THIS IS THE COLDEST AUGUST TEMPERATURE
SINCE 1986. DAYS WITH AN AVERAGE TEMPERATURE BELOW NORMAL TOTALED 17
FOR THE MONTH, COMPARED TO 12 DAYS FEATURING ABOVE NORMAL AVERAGE
TEMPERATURE.
PRECIPITATION FOR THE MONTH TOTALED 1.65 INCHES WHICH IS ABOUT AN
INCH AND THREE QUARTERS BELOW NORMAL. THERE WERE 11 DAYS WITH
MEASURABLE PRECIPITATION, WHICH IS ONE DAY GREATER THAN NORMAL, BUT
ALL EVENTS FEATURED LIGHT RAINFALL, WITH THE WETTEST DAY OCCURRING
ON THE 28TH WITH 0.35 INCHES OF PRECIPITATION. THE 6 DAYS WITH
THUNDERSTORMS IS EXACTLY NORMAL FOR THE MONTH OF AUGUST.
OVERALL AUGUST WAS A QUIET MONTH FOR WESTERN NEW YORK, FEATURING FEW
DAYS OF SHOWERS AND THUNDERSTORMS, WITH ONLY 1 DAY FEATURING STORMS
STRONG ENOUGH TO BE CONSIDERED SEVERE IN THE REGION. ON THE 6TH
SCATTERED SHOWERS AND THUNDERSTORMS FORMED THROUGH THE AFTERNOON AND
EARLY EVENING HOURS. ON THE 13TH A WEAKENING CONVECTIVE COMPLEX OF
THUNDERSTORMS PUSHED ACROSS WESTERN NEW YORK DURING THE MORNING
HOURS. AN AREA OF LOW PRESSURE BROUGHT A FEW ADDITIONAL SHOWERS ON
THE 19TH AND INTO THE 20TH WHICH WITH PREVIOUS RAIN ON THE 13TH
HELPED THE REGION TO RETURN SOME SHADE OF GREEN TO THE VEGETATION
FROM THE PREVIOUS BROWN TINT. ALONG A COLD FRONT ON THE 24TH SEVERAL
WATERSPOUTS FORMED OVER LAKE ERIE. INLAND, A FEW THUNDERSTORMS
INCREASED IN STRENGTH TO SEVERE LEVELS WITH A FEW TREES DOWN ACROSS
THE SOUTHERN TIER, AND HAIL UP TO AN INCH AND A HALF ACROSS THE
NORTHERN FINGER LAKES. AN ADDITIONAL WATERSPOUT FORMED ON LAKE
ONTARIO NORTH OF HILTON ON THE 26TH. A MUCH STRONGER COLD FRONT WITH
SHOWERS AND THUNDERSTORMS CROSSED WESTERN NEW YORK ON THURSDAY THE
28TH OF AUGUST. A VERY COLD AIRMASS BEHIND THE FRONT SENT THE
TEMPERATURE ON THE MORNING OF THE 30TH DOWN INTO THE LOWER 40S
ACROSS WESTERN NEW YORK, WITH SHELTERED AREAS OF THE HIGHER TERRAIN
SOUTH OF ROCHESTER REPORTING UPPER 30S.
WINDS FOR THIS RELATIVELY QUIET MONTH AVERAGED A THIRD OF A MILE PER
HOUR BELOW NORMAL. THE STRONGEST GUSTS WERE BEHIND A COLD FRONT ON
THE 25TH AND AGAIN ON THE 28TH, WITH A WEST GUST OF JUST 33 MPH
OCCURING BOTH DAYS. THE WATER TEMPERATURE ON LAKE ONTARIO PEAKED AT
77F NORTH OF ROCHESTER ON THE 14TH OF THE MONTH.
IN ALL A QUIET MONTH WITH MANY STRETCHES OF FINE OUTDOOR WEATHER.
