...A QUIET AND SUNNY MONTH...

AUGUST CAPPED OFF THE SUMMER OF 2013 FOLLOWING SIMILAR PATTERNS OF
JUNE AND JULY...NEAR NORMAL TEMPERATURES...WITH A LACK OF EXTREME
TEMPERATURES. RAINFALL WAS EVENLY SPREAD THROUGH THE MONTH...WITH
ONE STRETCH OF QUIET AND DRY WEATHER MID MONTH.

AUGUST AVERAGE TEMPERATURE FINISHED AT 69.0F WHICH IS ABOUT A HALF A
DEGREE BELOW NORMAL. THIS WAS THE FIRST AUGUST WITH BELOW NORMAL
TEMPERATURES AFTER FOUR PRIOR AUGUSTS OF ABOVE NORMAL WARMTH. TWO
THIRDS OF THE DAYS FINISHED WITHIN 5 DEGREES OF THE DAILY NORMAL AND
THERE WERE NO RECORDS SET. THE WARMEST DAY THIS MONTH WAS NEAR THE
END OF AUGUST...WHEN THE TEMPERATURE REACHED 86F ON THE 29TH.

PRECIPITATION FOR THE MONTH FINISHED AT 3.51 INCHES. THERE WAS
MEASURABLE RAINFALL ON 13 DAYS...WHICH IS JUST ABOVE THE NORMAL OF
10 DAYS. NO PRECIPITATION RECORDS WERE SET...AND THUNDERSTORMS
BROUGHT TWO DAYS (8TH AND 26TH) WITH OVER A HALF INCH OF RAINFALL.
IN TOTAL THERE WERE 13 DAYS WITH THUNDERSTORMS...WELL ABOVE THE
AVERAGE OF 6 FOR THE MONTH.

THE UPPER LEVEL PATTERN TO START THIS MONTH INVOLVED A MEAN
TROUGH OF LOW PRESSURE OVER EASTERN CANADA AND THE EASTERN UNITED
STATES...WITH A RIDGE CENTERED ALONG THE ROCKY MOUNTAINS OF THE
WEST. THIS PATTERN FAVORED COOLER THAN NORMAL DAYS WITH LATE SUMMER
HEAT SUPPRESSED TO THE SOUTH AND WEST. IN FACT ONLY 2 DAYS THIS
FIRST HALF OF THE MONTH WERE ABOVE NORMAL...ON THE 7TH AND 8TH WHEN
SOUTHERLY WINDS AHEAD OF A COLD FRONT BROUGHT LOW 80S INTO WESTERN
NEW YORK. THESE WARM TEMPERATURES ENDED WITH THE PASSAGE OF A COLD
FRONT ON THE 9TH WITH SHOWERS AND THUNDERSTORMS. A BROAD AREA OF
HIGH PRESSURE BROUGHT QUIET WEATHER MID MONTH...WITH TEMPERATURES
SLOWLY WARMING FROM BELOW NORMAL TO ABOVE NORMAL. THE SECOND HALF OF
THE MONTH THE UPPER LEVEL TROUGH OF LOW PRESSURE WEAKENED AND THIS
ALLOWED MORE WARMTH TO EXTEND NORTHEASTWARD ACROSS THE EASTERN GREAT
LAKES. ONLY 3 DAYS WERE BELOW NORMAL THE LAST 2 WEEKS OF THE MONTH
AS LATE SUMMER WARMTH RETURNED. SOME OF THE WARMEST DAYS THIS MONTH
OCCURRED THE LAST WEEK OF THE MONTH AS WARMTH AND HUMIDITY RETURNED
TO WESTERN NEW YORK ALONG WITH SEVERAL DAYS OF THUNDERSTORMS.
THUNDERSTORMS ON THE 26TH DARKENED AFTERNOON SKIES AND BROUGHT THE
GREATEST DAILY PRECIPITATION OF THE MONTH AS 0.70 INCHES OF RAINFALL
OCCURRED.

SUNSHINE FOR THE MONTH FINISHED 12 POINTS ABOVE NORMAL WITH 77
PERCENT SUNSHINE FOR THE MONTH. THERE WERE 21 MOSTLY SUNNY DAYS THIS
MONTH INCLUDING 7 WITH FULL SUNSHINE. WITH THE LACK OF ACTIVE WEATHER
THIS MONTH WINDS WERE BELOW NORMAL AND THE HIGHEST GUST ONLY 36 MPH.
LAKE ERIE WATER TEMPERATURES RANGED FROM 71 TO 73 DEGREES.

IN ALL AUGUST WILL GO DOWN AS A COMFORTABLE AND SUNNY MONTH.


...SUMMER NARRATIVE...

THIS SUMMER (JUNE-JULY-AUGUST) WAS FILLED WITH ITS UPS AND DOWNS FOR
TEMPERATURE AND PRECIPITATION...BUT IN THE END THE SUMMER OF 2013
WILL GO DOWN AS A NORMAL TEMPERATURE...AND ABOVE NORMAL
PRECIPITATION SEASON.

AFTER THREE CONSECUTIVE SUMMERS WITH ABOVE NORMAL TEMPERATURES THIS
SUMMER FELT COOL...BUT NUMBER-WISE THE AVERAGE TEMPERATURE OF 69.1F
FINISHED JUST A TENTH OF A DEGREE ABOVE NORMAL. THIS SUMMER
WAS FILLED WITH STRETCHES OF NOTABLY COOL...LATE SPRING OR EARLY
FALL PATTERNS...WITH SEVERAL STRETCHES OF SUMMER WARMTH MIXED IN.
JUNE FEATURED TEMPERATURES THAT RAN CLOSE TO NORMAL. THE WARMEST
STRETCH THIS SUMMER OCCURRED IN THE THIRD WEEK OF JULY WHEN
TEMPERATURES ROUTINELY REACHED THE UPPER 80S AND LOWER 90S AND NIGHT
TIME LOWS STRUGGLED TO DROP BELOW 70F. AFTER THIS STRETCH OF SUMMER
WARMTH ANOTHER FAIR AND COMFORTABLE PATTERN SETTLED UPON THE GREAT
LAKES REGION...WITH THE OCCASIONAL CHILLY NIGHT DROPPING BACK INTO
THE LOW 50S.

PRECIPITATION THIS SUMMER FINISHED MORE THAN THREE INCHES ABOVE
NORMAL. THIS WAS LARGELY DUE TO A WET JUNE WHERE SLOW MOVING
THUNDERSTORMS BROUGHT LOCALIZED FLOODING. THE MONTHS OF JULY AND
AUGUSTS FINISHED CLOSER TO NORMAL IN THE PRECIPITATION DEPARTMENT.
THERE WERE NO RECORD PRECIPITATION EVENTS THIS SUMMER. THERE WERE NO
PROLONGED DRY STRETCHES THIS SUMMER RESULTING IN AREA LAWNS AND
VEGETATION REMAINING GREEN THROUGH THE SUMMER.

IN ALL MUCH OF THIS SUMMER WAS COMFORTABLE WITH JUST A FEW
SHORT STRETCHES OF HIGH HUMIDITY AND SUMMER HEAT...BALANCED WITH
SEVERAL DAYS OF UNSEASONABLY COOL CONDITIONS.

SUMMER`S 3 MONTHS OF JUNE...JULY...AUGUST STATS (NORMAL)

TEMPERATURE...69.1F     (69.0F)

PRECIPITATION...13.53"  (10.15")

SUNSHINE...67%          (65%)
