...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 SPREAD THROUGH THE MONTH THOUGH IT DID
FAVOR THE FIRST HALF OF THE MONTH. THERE WAS ONE STRETCH OF
PLEASANT AND DRY WEATHER MID MONTH.

AUGUST AVERAGE TEMPERATURE FINISHED AT 69.3F WHICH IS EXACTLY
NORMAL. 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 MID MONTH...WHEN THE TEMPERATURE REACHED 87F ON THE 21ST.
THERE WERE 16 DAYS REACHING INTO THE 80S...ONE MORE THAN AUGUST
NORMAL.

PRECIPITATION FOR THE MONTH FINISHED AT 2.70 INCHES...ABOUT THREE
QUARTERS OF AN INCH BELOW NORMAL. THERE WAS MEASURABLE RAINFALL ON
10 DAYS...WHICH IS EXACTLY NORMAL. THERE WERE NO PRECIPITATION
RECORDS SET. IN TOTAL THERE WERE 6 DAYS WITH THUNDERSTORMS...WHICH
AGAIN IS EXACTLY AVERAGE FOR THE MONTH. THE 0.57 INCHES OF RAIN
THAT FELL ON THE 9TH WAS THE WETTEST DAY 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. THERE WERE ONLY 3 DAYS THE
FIRST HALF OF THE MONTH THAT FINISHED ABOVE NORMAL...ON THE 7TH
THROUGH THE 9TH 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.

THE LACK OF ACTIVE WEATHER THIS MONTH LEAD TO WINDS THAT AVERAGED
BELOW NORMAL AND THE HIGHEST GUST ONLY 36 MPH. LAKE ONTARIO
WATER TEMPERATURE PEAKED AT 74 DEGREES THIS MONTH.

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 SEEMED COOL...BUT NUMBER-WISE THE AVERAGE TEMPERATURE OF
69.6F FINISHED JUST UNDER 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 AND EARLY JULY WHERE SLOW
MOVING THUNDERSTORMS BROUGHT SOME LOCALIZED FLOODING. BOTH THE
REMAINDER OF JULY AND AUGUST FINISHED CLOSER TO NORMAL IN THE
PRECIPITATION DEPARTMENT. 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...69.6      (68.8)

PRECIPITATION...13.38"  (10.14)
