...RECORD BREAKING HEAT THIS AUGUST...

WARM TO UNCOMFORTABLY HOT DAYS AND MILD NIGHTS THROUGH AUGUST MADE
THIS MONTH THE WARMEST AUGUST ON RECORD, AND SECOND WARMEST MONTH
ALL-TIME. ALL BUT ONE DAY THIS MONTH AVERAGED ABOVE NORMAL IN
TEMPERATURES. THOUGH THE HEAT WAS CONSISTENT...IT WAS REALLY NOT
THAT EXTREME AS THERE WAS JUST ONE DAILY RECORD HIGH TIED THIS MONTH.
THERE WERE SEVERAL HOT AND STICKY DAYS, BUT FOR AUGUST THERE WAS
ALSO AN ABUNDANCE OF SUNNY DAYS WITH TOLERABLE HUMIDITY LEVELS.
SEVERAL HEAVY RAIN EVENTS THE LAST WEEK OF THE MONTH BROUGHT
PROMISING RELIEF FROM THE SHORT-TERM DROUGHT ACROSS THE REGION.

THE AVERAGE TEMPERATURE THIS MONTH WAS 75.9F WHICH WAS 6.6F DEGREES
ABOVE NORMAL, AND NEARLY A FULL DEGREE ABOVE THE PREVIOUS WARMEST
AUGUST ON RECORD. THERE WAS ONLY ONE WARMER MONTH IN HISTORY, JULY
1921 (77.8F). THERE WERE 29 DAYS THAT REACHED 80F OR GREATER, WHICH
IS THE GREATEST AMOUNT IN RECORDED HISTORY, BREAKING THE OLD RECORD
OF 26 DAYS SET BACK IN 1959. THERE WERE ALSO 10 DAYS THAT REACHED
INTO THE 90S, THIRD GREATEST NUMBER FOR THE MONTH OF AUGUST,
TRAILING ONLY 1944 (12 DAYS) AND 1947 (11 DAYS). THIS BROUGHT THE
TOTAL NUMBER OF DAYS IN THE 90S THIS SUMMER UP TO 24. THE HEAT WAS
CONSISTENT, WITH ONLY THE 22ND DAY OF THE MONTH AVERAGING BELOW
NORMAL. NIGHTTIME TEMPERATURES REMAINED MILD WITH 7 DAYS THIS MONTH
REMAINING IN THE 70S, WHICH IS TWO LESS THAN THE RECORD OF 9 NIGHTS
(1947). THERE WERE TWO RECORD WARM MINIMUM TEMPERATURES SET; ON THE
12TH AND 13TH OF THE MONTH THE LOWEST TEMPERATURE RECORDED BEING
75F. THE DAILY RECORD ON THE 12TH BROKE THE PREVIOUS RECORD FROM
1947, AND THE RECORD ON THE 13TH BROKE THE RECORD FROM 1988.

PRECIPITATION FOR THE MONTH TOTALED 3.91 INCHES WHICH IS ABOUT A
HALF INCH ABOVE NORMAL. THIS IS THE FIRST MONTH TO AVERAGE ABOVE
NORMAL PRECIPITATION SINCE MAY OF 2016, AND WAS THE WETTEST MONTH
SINCE LAST SEPTEMBER. THERE WERE TWO IMPACTFUL RAIN EVENTS, IN THE
SECOND HALF OF THE MONTH. ON THE 16TH DEEP SUB-TROPICAL MOISTURE
PASSED OVER THE REGION BRINGING WIDESPREAD STORMS, WITH JUST OVER AN
INCH OF RAIN FALLING AT THE ROCHESTER AIRPORT. ON THE FINAL DAY OF
THE MONTH 0.76 INCHES OF RAIN ACCUMULATED, BY BOTH MORNING SHOWERS.

AUGUST BEGAN IN SIMILAR FASHION AS JULY, WITH PERSISTENT WARMTH AND
SUNSHINE CONTINUING DRY CONDITIONS OVER WESTERN NEW YORK. THE
DROUGHT STRENGTHENED ITS GRIP ON WESTERN NEW YORK THROUGH THE FIRST
HALF OF THE MONTH AS PASSING COLD FRONTS WERE GENERALLY WEAK,
BRINGING JUST SPOTTY SHOWERS AND THUNDERSTORMS TO THE AREA. LAWNS
REMAINED PARCHED AND AREA FIELDS DRY. THE SECOND HALF OF THE MONTH
BROUGHT SOME RELIEF FROM THE DROUGHT AS TROPICAL MOISTURE BUILT OVER
THE EASTERN UNITED STATES. THIS MOISTURE COUPLED WITH COLD FRONT
PASSAGES BROUGHT AN INCREASE IN STORM ACTIVITY, WITH MEANINGFUL RAIN
FALLING ON THE 16TH, 20TH-21ST, 25TH AND 31ST OF THE MONTH. THIS
RAINFALL COUPLED WITH A LOWER SUN ANGLE ALLOWED FOR LAWNS TO RECOVER
FROM THE DROUGHT WITH GRASS RETURNING TO ITS GREEN LUSTER. HOWEVER
WATER TABLES, STREAMS AND CREEKS REMAINED LOW, WITH DROUGHT
CONDITIONS STILL PERSISTING.

WINDS AVERAGED 7.2 MPH THIS MONTH, JUST A FEW TICKS ABOVE NORMAL.
THE PEAK WIND GUST FOR THE MONTH WAS 41 MPH, THIS FOUND WITHIN A
GRADIENT WIND FLOWING ACROSS THE LAKE PLAIN ON THE AFTERNOON OF THE
16TH.

IN ALL...RECORD WARMTH, WITH SOME BENEFICIAL RAINS THE SECOND HALF.

METEOROLOGICAL SUMMER (JUNE, JULY, AUGUST) RECAP...

A CONTINUED QUIET STRETCH OVER THE EASTERN GREAT LAKES MADE FOR A
SPLENDID SUMMER FOR OUTDOOR ENTHUSIASTS. MANY DAYS WERE FULL OF
SUNSHINE, AND THERE WERE FEW STORMY DAYS. WHAT LITTLE RAIN THAT DID
FALL THIS SUMMER FELL MAINLY THROUGH THE OVERNIGHT AND EARLY MORNING
HOURS.

ROCHESTER FINISHED WITH THE 2ND WARMEST SUMMER ON RECORD (72.7F),
ECLIPSED BY ONLY THE SUMMER OF 1949 (73.0F). THE HEAT WAS
PERSISTENT, BUT NOT EXTREME AS THERE WAS JUST ONE RECORD HIGH
TEMPERATURE SET ON AUGUST 12TH (96F). THERE WERE A RECORD 72 DAYS
THAT REACHED INTO THE 80S (TIED 1973) AND 23 DAYS THAT TOPPED THE
90F MARK (4TH GREATEST). OVERNIGHT LOWS REMAINED ABOVE 70F ON 15
DAYS, TIED FOR 6TH GREATEST. ALL MONTHS AVERAGED ABOVE NORMAL, WITH
THE DEGREE OF ANOMALOUS WARMTH GREATER WITH EACH SUCCESSIVE MONTH.

A VERY DRY SUMMER PERSISTED THROUGH JUNE, JULY AND INTO THE FIRST
HALF OF AUGUST. SUMMER`S PRECIPITATION TOTALED 6.04 INCHES WHICH
PLACES THIS SUMMER 19TH DRIEST. THE DRY SPRING AND SUMMER PARCHED
AREA LAWNS AND FIELDS, NEGATIVELY IMPACTED AGRICULTURAL INTERESTS
AND LOWERED THE FLOW OF STREAMS AND CREEKS THROUGH THE REGION. A WET
SECOND HALF OF AUGUST BROUGHT SOME IMPROVEMENT AS LAWNS RETURNED TO
THEIR GREEN COLOR, THOUGH THE FLOW ON AREA STREAMS AND CREEKS
REMAINED LOW.

OVERALL THIS SUMMER WAS GREAT FOR OUTDOOR ACTIVITIES, BUT VERY POOR
FOR AGRICULTURE.

TEMPERATURE................72.7F  (+3.9F) 2ND WARMEST

PRECIPITATION.............6.04"   (-4.10") 19TH DRIEST
