...RECORD BREAKING HEAT THIS AUGUST...

WARM TO UNCOMFORTABLY HOT DAYS AND MILD NIGHTS THROUGH AUGUST MADE
THIS MONTH THE WARMEST AUGUST ON RECORD, AND THIRD WARMEST MONTH ALL-
TIME. ALL BUT ONE DAY THIS MONTH AVERAGED ABOVE NORMAL IN
TEMPERATURES. THOUGH THE HEAT WAS CONSISTENT...IT WAS NOT EXTREME AS
ONLY RECORDS OF OVERNIGHT WARM MINIMUM TEMPERATURES WERE BROKEN.
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 75.6F WHICH WAS A FULL 6
DEGREES ABOVE NORMAL, AND 0.4F DEGREES WARMER THAN THE PREVIOUS
WARMEST AUGUST ON RECORD. THERE WERE ONLY TWO WARMER MONTHS IN
HISTORY, JULY 1921 (76.2F) AND JULY 1955 (76.0F). THERE WERE 28
AUGUST DAYS THAT REACHED 80F OR GREATER, WHICH IS THE GREATEST
AMOUNT IN RECORDED HISTORY FOR THE MONTH, BREAKING THE OLD RECORD OF
26 DAYS SET BACK IN 1947. THERE WERE ALSO 4 DAYS THAT REACHED INTO
THE 90S, WHICH IS THREE MORE THAN AUGUST`S NORMAL, AND BROUGHT THE
TOTAL NUMBER OF DAYS IN THE 90S THIS SUMMER UP TO 8. THE HEAT WAS
CONSISTENT, WITH ONLY THE 22ND DAY OF THE MONTH AVERAGING BELOW
NORMAL. NIGHTTIME TEMPERATURES REMAINED MILD WITH 11 NIGHTS THIS
MONTH REMAINING IN THE 70S, WHICH IS ONE LESS THAN THE RECORD OF 12
NIGHTS (1900). THERE WERE TWO RECORD WARM MINIMUM TEMPERATURES SET;
ON THE 12TH AND 13TH OF THE MONTH THE LOWEST TEMPERATURE RECORDED
WAS 76F. THE DAILY RECORD ON THE 12TH TIED WITH 1988, AND THE DAILY
RECORD ON THE 13TH BROKE THE PREVIOUS DAILY RECORD WARM MINIMUM OF
75F SET IN 1918.

PRECIPITATION FOR THE MONTH TOTALED 4.17 INCHES WHICH IS NEARLY AN
INCH ABOVE NORMAL. THIS IS THE FIRST MONTH TO AVERAGE ABOVE NORMAL
PRECIPITATION SINCE FEBRUARY OF 2016, AND WAS THE WETTEST MONTH
SINCE LAST SEPTEMBER. THERE WERE THREE IMPACTFUL RAIN EVENTS, ALL IN
THE SECOND HALF OF THE MONTH. ON THE 16TH DEEP SUB-TROPICAL MOISTURE
PASSED OVER THE REGION BRINGING WIDESPREAD STORMS, WITH NEARLY THREE-
QUARTERS OF AN INCH OF RAIN FALLING AT THE BUFFALO AIRPORT. THE
SECOND OCCURRED ON THE 25TH WHEN HEAVY MORNING CONVECTIVE RAINS,
FOLLOWED BY ADDITIONAL AFTERNOON THUNDERSTORMS BROUGHT A DAILY
RECORD OF 1.54 INCHES OF RAIN, BREAKING THE FORMER RECORD OF 1.46
INCHES SET BACK IN 1982. ON THE FINAL DAY OF THE MONTH 0.89 INCHES
OF RAIN ACCUMULATED, FROM BOTH MORNING SHOWERS AND AFTERNOON
THUNDERSTORMS.

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, 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 8.6 MPH THIS MONTH, ABOUT A THIRD OF A MPH GREATER
THAN NORMAL. THE PEAK WIND GUST FOR THE MONTH WAS 44 MPH, THIS FOUND
WITHIN A GRADIENT WIND FLOWING OVER LAKE ERIE AND BUFFALO DURING THE
AFTERNOON HOURS. THE LAKE TEMPERATURE REMAINED WARM TO RECORD WARM
THROUGH THE MONTH FLUCTUATING BETWEEN 76F AND 79F DEGREES.

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 HOURS.

BUFFALO FINISHED WITH THE 3RD WARMEST SUMMER ON RECORD (72.4F),
ECLIPSED BY ONLY THE SUMMER OF 2005 (73.2F) AND 1949 (72.7F). THE
HEAT WAS PERSISTENT, BUT NOT EXTREME AS THERE WERE NO DAILY RECORD
HIGH TEMPERATURES SET. THERE WERE 66 DAYS THAT REACHED INTO THE 80S
(TIED 2ND GREATEST) AND 7 DAYS THAT TOPPED THE 90F MARK (TIED 12TH
GREATEST). OVERNIGHT LOWS REMAINED ABOVE 70F ON 21 DAYS, TIED FOR
3RD 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 7.28 INCHES WHICH
PLACES THIS SUMMER 42ND 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 VIBRANT 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................72.4F  (+3.2F) 3RD WARMEST

PRECIPITATION...............7.28" (-2.87") 42ND DRIEST
