A SEEMINGLY COOL MONTH OF AUGUST HAS FINISHED NEAR NORMAL AS A LATE MONTH SURGE OF SUMMERS WARMTH AND HUMIDITY DURING THE LAST WEEK OF THE MONTH BROUGHT TEMPERATURES BACK CLOSER TO NORMAL. THERE WERE NO 90 DEGREE DAYS THIS MONTH. AN ABUNDANCE OF SUNSHINE IN AUGUST MADE FOR A FINE END TO THE SUMMER. THE AVERAGE TEMPERATURE OF 68.2F WAS JUST OVER A DEGREE BELOW NORMAL. THE COOLEST DAY THIS MONTH WAS A MERE 67F DEGREES...WHICH WAS THE COOLEST MAXIMUM TEMPERATURE FOR AUGUST SINCE 2009 WHEN THERE WAS ALSO A 67F DEGREE READING. THE WARMEST TEMPERATURE OCCURRED DURING THE LAST WEEK OF THE MONTH WHEN ON BOTH THE 26TH AND 30TH THE AFTERNOON TEMPERATURE ROSE TO 87F DEGREES. THERE WERE NO TEMPERATURE RECORDS THIS MONTH. PRECIPITATION THIS MONTH WAS ABOUT AN INCH AND A QUARTER BELOW NORMAL...WHICH WAS WELCOMED AFTER A VERY WET JULY. MUCH OF THE RAIN CAME IN THUNDERSTORM DELUGES. A STORM ON THE 12TH BROUGHT NEARLY AN INCH OF RAINFALL. THERE WERE 10 DAYS WITH MEASURABLE RAINFALL WHICH IS AVERAGE. THE FIRST WEEK OF THE MONTH OF AUGUST STARTED WET AND COOL. FLASH FLOODING OCCURRED ON THE 2ND JUST TO THE SOUTH OF THE METRO AREA WHERE THUNDERSTORMS PRODUCED A TORRID OF RAINFALL. A WARM FRONT LIFTED NORTHWARD ACROSS WESTERN NEW YORK THE SECOND WEEK OF THE MONTH AND BROUGHT A BRIEF STRETCH OF SUMMER LIKE WEATHER WITH TEMPERATURES IN THE 80S AND A TOUCH OF HUMIDITY. THIS WARMTH WAS SHORT LIVED AS A COLD FRONT EASED ACROSS WESTERN NEW YORK ON THE 13TH...FOLLOWED BY A VERY COOL DAY ON THE 14TH. THIS COOL AIRMASS BROUGHT LAKE EFFECT RAIN OFF LAKE ERIE AND ACROSS PORTIONS OF WESTERN NEW YORK ON THE 14TH AND 15TH. THE LONGEST STRETCH OF DRY WEATHER THIS SUMMER STARTED ON SUNDAY THE 17TH. HIGH PRESSURE AND DRY FRONTAL PASSAGES ALLOWED THE REGION TO REMAIN DRY THROUGH SATURDAY THE 30TH. ONLY A FEW HUNDREDTHS FROM A PASSING SHOWER ON THE 27TH INTERRUPTED THIS STREAK. SUMMERS WARMTH RETURNED THE LAST WEEK OF THE MONTH. A FEW THUNDERSTORMS ON THE 30TH AND 31ST BROUGHT AN END TO THE DRY STRETCH...ONE THAT GAVE A BROWN TINT TO LOCAL LAWNS. WINDS FOR THE MONTH WERE GENERALLY LIGHT AND WITH THE LIGHT SYNOPTIC FLOW THIS MONTH STRONG WIND GUSTS WERE LACKING FROM THUNDERSTORMS. IN ALL A FINE END TO SUMMER ACROSS WESTERN NEW YORK.
