...VERY WARM/DRY CONDITIONS CONTINUE WITH A BRIEF PERIOD OF COOLER
WEATHER...

AFTER A VERY WARM/DRY MONTH OF JULY WHERE THE AVERAGE TEMPERATURE
RAN +3.7F ABOVE NORMAL...THE MONTH OF AUGUST WILL GO DOWN IN THE
RECORD BOOKS AS +1.3F ABOVE NORMAL. THE AVERAGE TEMPERATURE AT THE
ROCHESTER INTERNATIONAL AIRPORT WAS 70.6F. TEMPERATURES WARMED INTO
THE 80S ON 18 OF THOSE DAYS AND A FEW DAYS IN THE 90S. THIS MARKS
THE 4TH MONTH IN A ROW AND 8 OUT OF 9 MONTHS THAT THE AVERAGE
TEMPERATURE AT THE AIRPORT HAS BEEN ABOVE NORMAL FOR THE 2012
CALENDAR YEAR. WITH ALL THIS WARMTH...COOLER WEATHER DID DEVELOP FOR
A BRIEF PERIOD IN THE MONTH OF AUGUST. THE RESULT OF SEVERAL FRONTAL
PASSAGES AND A PERSISTENT TROUGH THAT RESIDED OVER THE GREAT LAKES
REGION. THIS WAS ESPECIALLY NOTICEABLE BETWEEN AUGUST 17TH THRU THE
22ND WHERE TEMPERATURES AVERAGED -4.1F DEGREES BELOW NORMAL.

RAINFALL DURING THIS PERIOD WAS BELOW NORMAL AGAIN IN THE ROCHESTER
AREA. THE TOTAL RAINFALL OF 2.73 INCHES AT THE ROCHESTER AIRPORT WAS
-0.74 INCHES BELOW NORMAL...MOST OF THIS RAIN FELL ON THE 5TH WHERE
THE AIRPORT RECEIVED 1.70 INCHES...WHICH PRODUCED A DAILY RAINFALL
RECORD...THE RESULT OF A COLD FRONT THAT PUSHED ACROSS WESTERN AND
NORTH CENTRAL NY WITH SHOWERS AND THUNDERSTORMS THAT PRODUCED AREAS
OF HEAVY RAINFALL ACROSS THE REGION. EVEN WITH THE LITTLE BIT OF
RAINFALL WE RECEIVED, IT WAS STILL NOT ENOUGH TO ALLEVIATE D1
MODERATE DROUGHT CONDITIONS ACROSS MOST LOCATIONS.

THE VERY WARM TEMPERATURES THAT STARTED THE BEGINNING OF THE MONTH
ALLOWED LAKE ONTARIO TO REACH A PEAK OF 77 DEGREES ON THE 7TH.
COOLER WEATHER HAS SLOWLY HELPED LAKE ONTARIO TO COOL OFF, WITH
CURRENT WATER TEMPERATURE OF 73F.

AUGUST WILL FINISH IN THE RECORD BOOKS REFLECTING A CONTINUATION OF
A WARM AND DRY SUMMER...DESPITE A BRIEF COOL DOWN.
