THE DROUGHT OF 2016 CONTINUED THROUGH THE MONTH OF JULY AS HOT AND SUN-FILLED DAYS TOOK A TOLL ON AREA VEGETATION. THUNDERSTORMS BROUGHT BRIEF, MAINLY LOCALIZED DOWNPOURS, WHICH BROUGHT LITTLE RELIEF TO THE LONG-TERM STRAIN ON AGRICULTURE AND AREA LAWNS. THE AIR TEMPERATURE AVERAGED ABOVE NORMAL THIS MONTH AS SUN-FILLED DAYS AND DRY GROUND ENABLED THE MONTHLY AVERAGE TEMPERATURE TO REACH 74.8F DEGREES. THIS AVERAGE IS FOUR DEGREES ABOVE NORMAL AND RANKS TIED FOR 7TH WARMEST JULY ON RECORD. A TYPICAL PATTERN THIS MONTH FEATURED BUILDING HEAT AND HUMIDITY, WITH TEMPERATURES REACHING AROUND 90F, FOLLOWED BY A COLD FRONT PASSAGE THAT BROUGHT BRIEF RELIEF TO THE HEAT AND HUMIDITY. ROCHESTER HAD NINE DAYS REACH INTO THE 90S WHICH IS FIVE DAYS MORE THAN NORMAL, AND GREATEST NUMBER OF DAYS IN THE 90S IN JULY SINCE 1988. THERE WERE NO RECORD TEMPERATURES ESTABLISHED THIS MONTH. PRECIPITATION TOTALED 1.22 INCHES WHICH IS MORE THAN 2 INCHES BELOW NORMAL. THE GREATEST RAINFALL TOTAL OF 0.42 INCHES ON THE 7TH ACCOUNTED FOR A THIRD OF THE MONTHLY RAINFALL. WHEN COMBINED WITH JUNE`S MEAGER RAINFALL TOTAL, THE JUNE-JULY TOTAL RAINFALL OF 2.13 INCHES RANKS 4TH DRIEST ALL TIME OVER THIS TWO MONTH STRETCH. THE OVERALL CONTINENTAL WEATHER PATTERN THIS MONTH FEATURED AN ANOMALOUSLY POSITIVE 500 HPA RIDGE OF HIGH PRESSURE OVER THE WEST COAST, AS WELL AS AN ANOMALOUSLY POSITIVE 500 HPA RIDGE OF HIGH PRESSURE OVER THE EASTERN COAST OF NORTH AMERICA. IN THE LOWER LEVELS SLIGHTLY COOLER TEMPERATURES AND LOWER THAN AVERAGE HEIGHTS OVER THE NORTHERN PLAINS AND SOUTHEASTERN CANADA ALLOWED FOR PERIODIC COOL FRONTS TO DROP ACROSS THE EASTERN GREAT LAKES REGION. THIS PATTERN OF SUNNY DAYS WITH BUILDING HEAT AND HUMIDITY UNDER A RIDGE OF HIGH PRESSURE, TO BE BROKEN BRIEFLY BY A COLD FRONT PASSAGE CONTINUED THROUGH THE MONTH. THUNDERSTORM COVERAGE VARIED WITH EACH COLD FRONT PASSAGE, AND STORMS WITH EACH FRONT DID NOT NECESSARILY PASS OVER THE AIRPORT. ASIDE FROM THUNDERSTORMS, MUCH OF WESTERN NEW YORK REMAINED VOID OF RAINFALL WHICH WORSENED THE DROUGHT CONDITIONS ACROSS THE REGION. LAWNS BECAME PARCHED AND BROWN, WHILE AGRICULTURE CROPS IN A SUN-BAKED GROUND WILTED WITHIN JULY`S HEAT. THE GREATEST RAINFALL EVENT THIS MONTH, A THUNDERSTORM, OCCURRED WITHIN AN HOUR ON THE LATE AFTERNOON OF THE 7TH. EVEN WITH THIS RAINFALL LAWNS SHOWED LITTLE RECOVERY FROM THE DROUGHT. WINDS AVERAGED JUST ABOVE NORMAL THIS MONTH, WITH THE AVERAGE WIND SPEED OF 8.4 MPH ABOUT A HALF A MILE PER HOUR GREATER THAN NORMAL. IN ALL ANOTHER DRY, SUNNY MONTH THAT CONTINUED THE DROUGHT OVER WESTERN NEW YORK. && THOMAS $$
