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 69.5F THIS MONTH WHICH IS ALMOST A DEGREE
BELOW NORMAL. THERE WERE THREE CONSECUTIVE DAYS IN THE 90S, THIS
OCCURRING ON THE 10TH THROUGH THE 12TH, WITH ALL THREE DAYS REACHING
91F. 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 16
FOR THE MONTH, COMPARED TO 13 DAYS FEATURING ABOVE NORMAL AVERAGE
TEMPERATURE.
PRECIPITATION FOR THE MONTH TOTALED 2.35 INCHES WHICH IS A LITTLE
LESS THAN AN INCH BELOW NORMAL. FOR THE PREVIOUS 15 MONTHS, ALL BUT
ONE HAS FINISHED WITH BELOW NORMAL PRECIPITATION. THE 6 DAYS WITH
MEASURABLE PRECIPITATION TIES FOR 10TH FEWEST ON RECORD. THE
WETTEST DAY WAS AUGUST 17TH WHEN MULTIPLE ROUNDS OF SHOWERS AND
THUNDERSTORMS BROUGHT 0.95 INCHES OF PRECIPITATION TO THE BUFFALO
AIRPORT. STILL THROUGH THE END OF THE MONTH 427 CONSECUTIVE DAYS
HAVE FEATURED LESS THAN AN INCH OF PRECIPITATION, 4TH LONGEST STREAK
IN BUFFALO`S 155 YEARS OF RECORD.
OVERALL AUGUST WAS A QUIET MONTH FOR WESTERN NEW YORK, FEATURING FEW
DAYS OF SHOWERS AND THUNDERSTORMS, AND ONLY 2 DAYS FEATURING STORMS
STRONG ENOUGH TO BE CONSIDERED SEVERE IN THE REGION. ON THE 6TH
SCATTERED SHOWERS AND THUNDERSTORMS FORMED, MAINLY TO THE NORTH AND
EAST OF THE BUFFALO AIRPORT, WITH BRIEF, POOR DRAINAGE FLOODING
ACROSS THE NORTHTOWNS. ON THE 13TH A WEAKENING CONVECTIVE COMPLEX OF
THUNDERSTORMS PUSHED ACROSS WESTERN NEW YORK DURING THE MORNING
HOURS, WHILE A LAKE BREEZE CONVERGENT BOUNDARY BROUGHT A THIN LINE
OF SHOWERS ACROSS NORTHERN ERIE COUNTY DURING THE AFTERNOON. ON THE
17TH A CLUSTER OF SHOWERS AND THUNDERSTORMS IN THE MORNING, FOLLOWED
BY SCATTERED SHOWERS DURING THE AFTERNOON BROUGHT NEARLY AN INCH OF
RAIN TO THE BUFFALO AIRPORT. THIS RAIN, COMBINED WITH RAIN ON THE
13TH HELPED TO RETURN THE BROWN VEGETATION BACK TO A SHADE OF GREEN.
THE CONVECTION ON THE 17TH ALSO BROUGHT DOWN A FEW TREES IN WESTERN
CHAUTAUQUA COUNTY. AN AREA OF LOW PRESSURE BROUGHT A FEW ADDITIONAL
SHOWERS ON THE 19TH AND INTO THE 20TH. 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. 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 BUFFALO REPORTING UPPER 30S.
WINDS FOR THIS RELATIVELY QUIET MONTH AVERAGED A MILE PER HOUR BELOW
NORMAL. THE STRONGEST GUSTS WERE ASSOCIATED WITH THE COLD FRONT ON
THE 24TH AND 28TH, WITH A SOUTHWEST GUST OF JUST 37 MPH BOTH DAYS.
LAKE ERIE`S WATER TEMPERATURE DROPPED FROM 77F AT THE BEGINNING OF
THE MONTH DOWN TO 70F FOR THE FINAL DAYS OF AUGUST. THIS 70F DEGREE
READING ON THE MONTH`S FINAL DAY IS 1 DEGREE LOWER THAN NORMAL.
IN ALL A QUIET MONTH WITH MANY STRETCHES OF FINE OUTDOOR WEATHER.
