...SUMMER HEAT GIVES WAY TO COOLER TEMPERATURES AND BENEFICIAL
RAINFALL...

SEPTEMBER TEMPERATURES ENDED UP BEING 1.3 DEGREES ABOVE AVERAGE...
BUT THE MONTH WAS DIVIDED INTO TWO DISTINCT PERIODS. THE HEAT THAT
WAS SO COMMON THIS SUMMER LASTED INTO THE FIRST WEEK OF SEPTEMBER
WITH ALL OF THE FIRST 8 DAYS WELL ABOVE AVERAGE. NO RECORD HIGH
TEMPERATURES WERE SET DURING THIS STRETCH...BUT MOST DAYS WERE CLOSE
TO 10 DEGREES ABOVE AVERAGE. THE PATTERN FINALLY BROKE DURING THE
SECOND WEEK OF THE MONTH AS A TROUGH BECOME ESTABLISHED ACROSS MUCH
OF THE NORTH CENTRAL AND NORTHEAST UNITED STATES. DURING THE LAST 22
DAYS OF THE MONTH 15 WERE BELOW AVERAGE...QUITE A CHANGE FROM THE
PERSISTENT WARMTH OF SPRING AND SUMMER.

THERE WAS 4.39 INCHES OF PRECIPITATION FOR THE MONTH...WHICH WAS
CLOSE TO A HALF INCH ABOVE AVERAGE. THE ABOVE AVERAGE RAINFALL WAS
WELCOME FOLLOWING A DROUGHT THAT LASTED MUCH OF THE SPRING AND
SUMMER. IN FACT...THIS WAS THE FIRST MONTH WITH ABOVE AVERAGE
PRECIPITATION SINCE APRIL. THE RAIN HELPED TO ALLEVIATE DRY SOIL
CONDITIONS...BUT MORE PRECIPITATION WILL BE NEEDED TO ALLOW GROUND
WATER TO FULLY RECOVER. THE ABOVE NORMAL PRECIPITATION WAS A LITTLE
DECEIVING...SINCE OVER HALF OF THIS OCCURRED ON JUST TWO DAYS WITH A
RECORD DAILY RAINFALL OF 1.32 INCHES ON THE 4TH FOLLOWED BY 1.17
INCHES OF RAIN ON THE 8TH.

WITH MOST OF THE RAIN FALLING IN SEVERAL SIGNIFICANT EVENTS...THERE
WERE STILL PLENTY OF DRY STRETCHES FOR OUTDOOR WORK AND ACTIVITIES.
SUNSHINE WAS ALSO WELL ABOVE AVERAGE AT 73 PERCENT OF POSSIBLE...
WITH AVERAGE BEING 57 PERCENT FOR THE MONTH OF SEPTEMBER.

LAKE ERIE WATER TEMPERATURES STARTED THE MONTH ABOUT 2 DEGREES ABOVE
AVERAGE AFTER THE LONG HOT SUMMER...BUT COOLER WEATHER DURING THE
MIDDLE AND END OF SEPTEMBER DROPPED THE LAKE TEMPERATURE TO AVERAGE
BY THE END OF THE MONTH.
