...QUIET AUGUST ENDS A NEAR NORMAL SUMMER...


CONSISTENCY HAS BEEN THE THEME THROUGH THE SUMMER, WITH NO MAJOR
EXTREMES IN TEMPERATURE AND PRECIPITATION...AND THAT CONTINUED
THROUGH THE MONTH OF AUGUST. PLEASANT AFTERNOONS WERE OCCASIONALLY
INTERRUPTED BY SUMMER`S WARMTH AND HIGH HUMIDITY.

THE AVERAGE TEMPERATURE THIS MONTH WAS 68.6F, WHICH IS 0.7F DEGREES
BELOW NORMAL. THE WARMEST DAY WAS THE 2ND, WHEN TEMPERATURES TOPPED
OUT AT 87F. FOR THE MONTH THERE WERE 14 DAYS THAT REACHED THE 80S, 1
LESS THAN NORMAL, AND 15 DAYS FEWER THAN LAST AUGUST, WHICH WAS THE
WARMEST AUGUST ON RECORD. TEMPERATURES AVERAGED NEAR NORMAL THE
FIRST THREE WEEKS OF THE MONTH, THEN COOLER AIR SETTLED ACROSS THE
REGION TO CLOSE OUT THE MONTH WITH THE LAST 9 DAYS AVERAGING ABOUT 5
DEGREES BELOW NORMAL.

PRECIPITATION TOTALED 3.20 INCHES FOR THE MONTH, WHICH IS ABOUT A
QUARTER OF AN INCH BELOW NORMAL. THE WETTEST DAY WAS THE 22ND, WHEN
SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS BROUGHT 0.78 INCHES OF
RAIN TO THE ROCHESTER AIRPORT. THERE WERE 10 DAYS WITH MEASURABLE
RAINFALL THIS MONTH, WHICH IS NORMAL.

THERE WERE TWO DAYS WITH A SIGNIFICANT AMOUNT OF DAMAGE FROM SEVERE
THUNDERSTORMS ACROSS WESTERN NEW YORK. THE FIRST DAY WAS FRIDAY
AUGUST 4TH WHEN SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS PASSED
ACROSS THE REGION, WITH DAMAGING WIND GUSTS. THE SECOND EVENT
OCCURRED ON THE 22ND, WITH AGAIN SEVERAL ROUNDS OF SHOWERS AND
THUNDERSTORMS CROSSING WESTERN NEW YORK, PRODUCING DAMAGING WINDS
BEFORE THE MAIN COLD FRONT PASSED THROUGH IN THE EARLY MORNING HOURS
OF THE 23RD. OUTSIDE OF THESE TWO EVENTS, QUIET WEATHER REMAINED
WITH JUST A FEW INSTANCES OF MAINLY GARDEN VARIETY SHOWERS AND
THUNDERSTORMS.

WINDS AVERAGED ABOUT NORMAL THIS MONTH, WITH AN AVERAGE SPEED OF 7.3
MPH THREE TENTHS OF A MILE PER HOUR GREATER THAN NORMAL. THE
GREATEST GUST CAME ON THE 4TH, WHEN THUNDERSTORMS PRODUCED A GUST OF
50 MPH AT THE AIRPORT.

IN ALL, A STEADY CLOSE TO SUMMER.
