JULY FEATURED TYPICAL MID-SUMMER CONDITIONS WITH 24 DAYS THIS MONTH WITHIN 3 DEGREES OF NORMAL TEMPERATURE. THERE WERE NO MAJOR EXTREMES IN THE TEMPERATURES THOUGH SEVERAL DAYS THROUGH THE MONTH EXHIBITED SUMMER`S HIGH HUMIDITY. THERE WERE TWO WEATHER EVENTS MID MONTH THAT BROUGHT SIGNIFICANT WEATHER (FLASH FLOODING, TORNADOES) TO BUFFALO. THE AVERAGE TEMPERATURES THIS MONTH WAS 70.7F WHICH IS A HALF A DEGREE BELOW NORMAL. THE WARMEST DAY THIS MONTH WAS 87F ON JULY 5TH. THERE WERE NO 90 DEGREE READINGS THIS MONTH FOR THE SECOND TIME THIS DECADE, WITH 2014 THE OTHER YEAR WITHOUT A 90 DEGREE READING IN JULY. PRECIPITATION FOR THE MONTH TOTALED 4.65 INCHES, WHICH IS ABOUT AN INCH AND A HALF ABOVE NORMAL. HALF OF THIS RAIN FELL IN ONE DAY...ON THE 13TH WHEN A NEW DAILY RECORD OF 2.29 INCHES OF PRECIPITATION WAS SET. THE FORMER PRECIPITATION RECORD WAS 1.86 INCHES SET BACK IN 1956. THERE WERE 7 THUNDERSTORMS THIS MONTH, ONE MORE THAN NORMAL. THERE WERE TWO SIGNIFICANT EVENTS THIS MONTH. THE FIRST ON THE 12TH- 13TH WHEN A WARM FRONT STALLED ACROSS WESTERN NEW YORK. ON WEDNESDAY THE 12TH, SEVERAL INCHES OF RAIN FELL ACROSS WESTERN NEW YORK, INCLUDING ACROSS THE SOUTHERN TIER, AND TO THE EAST OF BUFFALO. THROUGH THE MORNING HOURS OF THE 13TH ANOTHER WAVE A HEAVY RAIN FELL ALONG THIS SAME WARM FRONT BOUNDARY, INCLUDING ACROSS DOWNTOWN BUFFALO AND THE METRO AREA WHERE SEVERAL INCHES OF RAIN FELL IN JUST A FEW HOURS. NUMEROUS ROADS WERE FLOODED ACROSS THE BUFFALO METRO AREA, AS WELL AS ACROSS GENESEE AND WYOMING COUNTIES. AREA CREEKS ALSO ROSE RAPIDLY, ESPECIALLY CAYUGA CREEK WHICH PEAKED AT MODERATE AND ITS FIFTH HIGHEST GAUGE READING IN RECORD KEEPING. THE SECOND EVENT WAS JUST A WEEK LATER, ON THE 20TH, AND WAS A NORTHWEST FLOW EVENT IN WHICH A COMPLEX OF THUNDERSTORMS DROPPED ACROSS THE REGION FROM THE NIAGARA PENINSULA. THESE STORMS, INITIALLY BRINGING DAMAGING WINDS INTERACTED WITH A FRONTAL BOUNDARY DRAPED ACROSS THE REGION TO SPAWN FOUR TORNADOES. THE FIRST TWO TORNADOES WERE IN SOUTHERN ERIE COUNTY AND WERE THE FIRST TORNADOES IN ERIE COUNTY SINCE 2006. THE FIRST TORNADO CROSSED HAMBURG, INCLUDING THE ERIE COUNTY FAIRGROUNDS, WHILE THE SECOND TORNADO THIS DAY CROSSED HOLLAND. IN ADDITION TO DOWNING MANY TREES, THE TORNADO THROUGH HAMBURG CAUSED DAMAGE TO THE FAIRGROUNDS WHILE ALSO BLOWING OUT THE WINDOWS OF HUNDREDS OF CARS. A THIRD AND FOURTH TORNADO DEVELOPED LATER ACROSS ALLEGANY COUNTY IN THE TOWNS OF RUSHFORD AND ANGELICA. THESE TORNADOES UPROOTED TREES, WITH THE FOURTH TORNADO ACROSS ANGELICA ALSO DESTROYING A BARN AND SEVERAL SHEDS. WINDS WERE LIGHT FOR THE MONTH, AVERAGING 8.3 MPH WHICH IS 0.7 MPH BELOW NORMAL. LAKE ERIE LINGERED NEAR NORMAL THROUGH THE MONTH IN THE LOW TO MID 70S. IN ALL IT WAS PLEASANT THROUGH MUCH OF THE MONTH. && THOMAS $$
