... A MORE TYPICAL MONTH FOR A CHANGE ...
A LONG DURATION OF INCREDIBLE WARMTH THAT STARTED LATE IN 2023
FINALLY BUCKLED THIS MONTH, WITH AIR TEMPERATURES FINISHING LESS
THAN A DEGREE FROM NORMAL. THIS IS THE FIRST MONTH WITHIN A DEGREE
OF NORMAL, OR BELOW NORMAL TEMPERATURE SINCE NOVEMBER OF 2023. THE
NOTABLE WEATHER MAKER THIS MONTH WAS THE REMNANTS OF HURRICANE
DEBBY, WHICH BROUGHT HEAVY RAIN ALONG AND EAST OF THE GENESEE VALLEY
ON AUGUST 9TH.
THE TEMPERATURE AVERAGED 70.9F THIS MONTH WHICH IS LESS THAN A
DEGREE ABOVE NORMAL. THE 13 DAYS WITH BELOW NORMAL TEMPERATURE THIS
MONTH IS THE GREATEST FOR ANY MONTH SINCE NOVEMBER OF LAST YEAR.
BEHIND A STRONG COLD FRONT THE AIR TEMPERATURE AVERAGED 10 DEGREES
BELOW NORMAL ON THE 20TH AND 21ST, THE FIRST TIME WITH A DOUBLE
DIGIT NEGATIVE DEPARTURE FROM NORMAL SINCE JUNE 10TH OF THIS YEAR.
THE WARMEST TEMPERATURE FOR THE MONTH OCCURRED ON THE 1ST, AT 91F
DEGREES. THIS IS THE EIGHTH 90 READING THIS SUMMER.
PRECIPITATION FOR THE MONTH TOTALED 3.53 INCHES WHICH IS ABOUT A
QUARTER OF AN INCH ABOVE NORMAL. THE THREE DAYS WITH A HALF INCH OR
MORE OF PRECIPITATION IS ONE DAY GREATER THAN NORMAL. THERE WERE NO
PRECIPITATION RECORDS SET THIS MONTH.
AUGUST BEGAN ON A HUMID NOTE, WITH A FEW THUNDERSTORMS BLOSSOMING
THROUGH THE AFTERNOON HOURS. THE FIRST RAINFALL AT THE BUFFALO
AIRPORT HELD OFF TILL THE 2ND AS A WARM FRONT AND ASSOCIATED SHOWERS
AND THUNDERSTORMS ALONG THE BOUNDARY CROSSED THE REGION EARLY IN THE
MORNING ON THE 2ND. ANOTHER SYSTEM BROUGHT ADDITIONAL SHOWERS AND
THUNDERSTORMS TO THE AIRPORT ON THE 3RD OF THE MONTH. COOLER AIR
BEGAN TO POUR OVER WESTERN NEW YORK ON THE 5TH. ALONG A LAKE BREEZE
BOUNDARY A TORNADO, WITH INITIAL ROOTS NEAR FORT ERIE CANADA,
QUICKLY PASSED OVER THE CITY OF BUFFALO. THIS 1.4 MILE TORNADO WAS
RATED EF-1 WITH SOME DAMAGE TO AREA HOMES, BUSINESSES, TREES AND
PROPERTY. NOT SOON AFTER THE REMNANTS OF HURRICANE DEBBY PASSED
ACROSS WESTERN NEW YORK ON THE 9TH. THE AXIS OF HEAVY RAIN FROM
DEBBY REMAINED ACROSS THE GENESEE VALLEY AND FINGER LAKES, WITH
SIGNIFICANT FLOODING IN THE UPPER GENESEE VALLEY TO THE SOUTHERN
FINGER LAKES. AFTER THIS EVENT THE WEATHER REMAINED FAIRLY QUIET FOR
THE REMAINDER OF THE MONTH, OUTSIDE OF HEAVY RAIN LATE ON THE 18TH
AND INTO THE MORNING HOURS OF THE 19TH WITH AN INCH TO INCH AND A
HALF OF RAIN FALLING ACROSS THE ROCHESTER METRO AREA. A FEW SEVERE
THUNDERSTORMS ALONG THE SOUTHERN LAKE ONTARIO SHORELINE ON THE 11TH,
AND A FEW SEVERE THUNDERSTORMS ACROSS THE SOUTHERN TIER AND BOSTON
HILLS ON THE 17TH ROUNDED OUT THE MONTH.
THE WATER TEMPERATURE FOR LAKE ONTARIO, MEASURED NEAR ROCHESTER,
REACHED A PEAK OF 78F DEGREES FOR THE MONTH. THIS IS ALSO THE
HIGHEST TEMPERATURE MEASURED FOR THE SUMMER. THE WINDS WERE JUST
ABOVE NORMAL BY A TENTH OF A MILE PER HOUR, AND THE STRONGEST GUST
WAS FROM THE WEST AT 42 MPH DURING THE LATE MORNING HOURS OF THE
10TH.
IN ALL A TREND TO MORE TYPICAL TEMPERATURES TO CLOSE OUT A TOP 10
WARMEST SUMMER ON RECORD.
