SUMMER’S CONVECTION WAS UPON WESTERN NEW YORK THIS JULY, WITH SEVERAL ROUNDS OF THUNDERSTORMS, OF WHICH SOME PRODUCED LOCALLY HEAVY DOWNPOURS. A PERSISTENT UPPER LEVEL LOW SOUTH OF HUDSON BAY THIS MONTH KEPT UNSETTLED DAYS THROUGHOUT THE GREAT LAKES REGION, WHILE ALSO SUPPRESSING MUCH OF THE BLAZING SUMMER HEAT TO THE SOUTH. MOST DAYS WERE NEAR OR JUST ABOVE THEIR DAILY TEMPERATURE NORMALS. PRECIPITATION WAS MUCH ABOVE NORMAL WITH THE MONTH FINISHING IN THE TOP 15 WETTEST ON RECORD. THE TEMPERATURE FOR JULY AVERAGED 72.8F WHICH IS ABOUT A DEGREE ABOVE NORMAL. WHILE MUCH OF THE MONTH HAD HIGHS IN THE 70S OR 80S, THERE WAS ONE HOT DAY, WITH THIS BEING THE 6TH AT 91F. THIS DAY WAS ALSO MET WITH HIGH HUMIDITY THAT BROUGHT APPARENT TEMPERATURES WELL INTO THE 90S. THE 17 DAYS WITH HIGHS IN THE 80S IS JUST ONE DAY LESS THAN THE AIRPORT NORMAL FOR JULY. PRECIPITATION TOTALED 5.54 INCHES WHICH IS MORE THAN TWO INCHES ABOVE NORMAL. THIS TOTAL ALSO RANKS 11TH WETTEST ON RECORD FOR JULY. THERE WERE 2 DAYS WITH OVER AN INCH OF RAIN FROM THUNDERSTORMS, THESE BEING THE 20TH AND 27TH OF THE MONTH. EARLY MONTH PRECIPITATION DEPARTURES WERE NOT FAR FROM NORMAL, BUT A WET SECOND HALF TO THE MONTH ESCALATED THE DEPARTURE TO OVER TWO INCHES. THE MONTH TENDED TO BE CLOUDIER THAN NORMAL, WITH COMPLETE SUNNY DAYS FEW IN NUMBER. AN ALL DAY RAIN EVENT, WITH VERY LITTLE THUNDER OCCURRED ON THE 2ND OF THE MONTH. OTHERWISE MUCH OF THE PRECIPITATION THIS MONTH WAS WITHIN THUNDERSTORMS, WITH THESE STORMS BEING GARDEN VARIETY NEAR BUFFALO, BUT STRONGER OUTSIDE THE METRO AREA. NOTABLE DATES FOR STORMS INCLUDE THE 6TH WITH A STORM CROSSING GRAND ISLAND, THE 20TH WITH WIDESPREAD SEVERE STORMS SOUTH OF THE BUFFALO METRO AREA AND THE 26TH WITH A MID EVENING LINE OF THUNDERSTORMS. THOUGH THE RAINS KEPT THE AREA VEGETATION LUSH THROUGHOUT THE MONTH, DEEP SOIL MOISTURE CONTENT CONTINUED TO BE ABNORMALLY DRY. THOUGH A WET MONTH, 3 OF THE 5 WEEKENDS WERE RELATIVELY DRY WITH ANY RAIN EITHER VERY EARLY OR VERY LATE IN THE WEEKEND. THE FINAL WEEKEND FEATURED RAIN AND SOME THUNDER ON SATURDAY BUT A BEAUTIFUL FINISH ON SUNDAY WITH SUNSHINE AND LOW HUMIDITY. WILDFIRE SMOKE WAS LESS IMPACTFUL THIS MONTH THAN RECENT MONTHS, WITH THE 17TH-18TH AND AGAIN THE 26TH REPORTING SMOKE WITH REDUCED SURFACE VISIBILITY AND HIGHER FINE PARTICULATE MATTER. THE WATER TEMPERATURE ON LAKE ERIE PEAKED AT 74F THIS MONTH, WHICH IS A DEGREE ABOVE NORMAL FOR THE MONTH. SEVERAL WATERSPOUTS OCCURRED ON THE FINAL DAY OF THE MONTH OFF THE SHORELINE OF LAKE ERIE NEAR HAMBURG. WINDS AVERAGED BELOW NORMAL BY JUST OVER A MILE PER HOUR. THE STRONGEST WIND GUSTS OF 46 MPH OCCURRED DURING A THUNDERSTORM DURING THE EVENING HOURS OF THE 20TH. IN ALL CLOUDY, WET JULY WITH TYPICAL SUMMER HEAT. && THOMAS $$
