SUMMER`S HEAT WAS HARD TO COME BY THIS MONTH AS ANY BUILDING WARMTH WAS QUICKLY ERASED BY A SURGE OF COOLER AIR. THOUGH COOL FOR THE MONTH...THERE WERE STILL A NUMBER OF COMFORTABLE DAYS FOR MOST OUTDOOR ACTIVITIES. THUNDERSTORMS...SOME WITH TORRENTIAL DOWNPOURS BROUGHT FLOODING AND HIGHER THAN NORMAL JULY RAINFALL. THE AVERAGE TEMPERATURE OF 68.6F WAS TWO AND A HALF DEGREES BELOW THE NORMAL OF 71.1F. THERE WERE NO 90 DEGREE DAYS THIS MONTH AND THERE WERE ONLY 8 DAYS IN THE 80S. THIS MONTH WAS THE COOLEST JULY SINCE 2009 WHEN THE AVERAGE TEMPERATURE WAS JUST 66.9F AND THE NUMBER OF 80 DEGREE DAYS STOOD AT JUST TWO. THERE WERE NO RECORDS THIS MONTH AND THE WARMEST DAY OCCURRED ON THE 1ST WHEN THE TEMPERATURE REACHED 86F. PRECIPITATION TOTALED 5.45 INCHES AT THE AIRPORT. THIS TOTAL IS A SOLID TWO INCHES ABOVE NORMAL...AND ALL RAINFALL FELL AS NON TROPICAL. DAYS WITH PRECIPITATION WAS SPREAD EVENLY THROUGH THE MONTH. HEAVY STORMS BROUGHT FIVE DAYS THIS MONTH WITH HALF INCH OR MORE OF RAINFALL. THESE FIVE JULY DAYS ARE TWO SHY OF THE RECORD OF SEVEN DAYS WHICH OCCURRED IN 1992...AND IS THE SECOND MOST NUMBER OF DAYS IN JULY SINCE THE MOVE TO THE AIRPORT IN THE SUMMER OF 1943. THERE WERE NINE DAYS WITH THUNDER THIS MONTH...AND DESPITE ALL THE HEAVY STORMS THERE WERE NO DAILY PRECIPITATION RECORDS. THE OVERALL UPPER LEVEL PATTERN THIS MONTH FEATURED A TROUGH EXTENDING SOUTHWARD FROM HUDSON BAY ACROSS THE GREAT LAKES REGION. THIS ALLOWED FOR COOL AIR FROM THE NORTH TO PERIODICALLY DROP SOUTHWARD ACROSS THE EASTERN GREAT LAKES REGION. WHILE THERE WERE COOL PERIODS THERE WERE ALSO BRIEF STRETCHES OF SUMMER-TIME WARMTH. JULY`S WARMEST DAY CAME ON THE 1ST AND THIS WARMTH CONTINUED INTO THE 2ND DAY OF THE MONTH WITH JUST SOME SCATTERED EVENING SHOWERS AND THUNDERSTORMS. A SLOW MOVING COLD FRONT BROUGHT A LITTLE MORE ACTIVITY ON THE 3RD...WITH SHOWERS AND THUNDERSTORMS CLEARING THE REGION BY THE START OF THE 4TH OF JULY. A SPLENDID 3-DAY HOLIDAY WEEKEND ENSUED WITH PLENTY OF SUNSHINE AND SEASONABLE TEMPERATURES. A WARM FRONT LIFTED NORTHWARD ACROSS THE EASTERN GREAT LAKES REGION ON THE 7TH AND THUNDERSTORMS ALONG THIS BOUNDARY SOAKED BUFFALO WITH JUST OVER AN INCH OF RAINFALL. THE FIRST MAJOR OUTBREAK OF SEVERE THUNDERSTORMS THIS MONTH OCCURRED ON THE 8TH. A MINIATURE DERECHO UNFOLDED TUESDAY AFTERNOON AND BROUGHT WIDESPREAD DAMAGE ACROSS SOUTHERN NEW YORK STATE...AND INTO THE GENESEE VALLEY. MUCH OF THE BUFFALO METRO AREA WAS SPARED DAMAGE FROM THIS SYSTEM. THROUGH THE MIDDLE PORTION OF JULY AIRMASSES ALTERNATED BETWEEN WARM AND MUGGY AND COOL AND DRY. THUNDERSTORMS AS THESE AIRMASSES CLASHED OCCURRED THROUGH THE MONTH...THOUGH MOST STORMS WERE RELATIVELY TAME. A FEW STORMS DEVELOPED ON THE 14TH ON AN OLD OUTFLOW BOUNDARY AND DID BRING LOCALIZED HAIL AND HEAVY DOWNPOURS...WITH SOME DAMAGE ACROSS THE NORTHERN FINGER LAKES REGION. TEMPERATURES WARMED AGAIN WITH SUMMER`S WARMTH OF TEMPERATURES IN THE 80S FOUND ACROSS THE REGION FROM THE 21ST THROUGH THE 23RD. AHEAD OF A DEEP UPPER LEVEL LONG WAVE TROUGH MOISTURE LADEN STORMS BROUGHT HEAVY RAINS TO THE BUFFALO METRO AREA ON THE NIGHT OF THE 27TH AND LATER THROUGH THE DAY ON THE 28TH. THE MONTH FINISHED COOL WITH A FALLISH FEEL TO THE AIR. LAKE ERIE FLUCTUATED BETWEEN 71 AND 73 DEGREES THIS MONTH WHICH IS NORMAL. SUNSHINE WAS A LITTLE ABOVE NORMAL AS 20 MOSTLY SUNNY DAYS THIS MONTH BROUGHT SUNSHINE TO FOUR PERCENT ABOVE NORMAL. WINDS WERE NORMAL THIS MONTH AND THE STRONGEST GUST OF 56 MPH OCCURRED WITHIN A THUNDERSTORM ON JULY 8TH. OVERALL A COOL AND WET MONTH FOR WESTERN NEW YORK. && $$ THOMAS
