THE EXCEPTION WAS THE SECOND WEEK OF THE MONTH WHEN A COLD FRONT BROUGHT A DRY AIR MASS INTO THE AREA WITH WARM DAYS AND COOL NIGHTS. THE COOLEST TEMPERATURE OF THE MONTH WAS 49 DEGREES ON THE 7TH. THE WARM WEATHER RETURNED FOR THE THIRD WEEK WITH SEVERAL DAYS ABOVE 90 DEGREES. THUNDERSTORMS BROUGHT HEAVY RAINFALL ON THE 18TH WITH 2.48 INCHES OBSERVED IN JUST A FEW HOURS. OBSERVATIONS WERE MISSING ON THE 19TH AND 20TH DUE TO EQUIPMENT FAILURE. THE AVERAGE TEMPERATURE FOR THE MONTH WAS 70.8 DEGREES WHICH WAS 2.3 DEGREES ABOVE NORMAL. DUE TO EQUIPMENT FAILURE, 2 DAYS OF TEMPERATURE DATA WERE MISSING WHICH WILL CAUSE AN UNDER ESTIMATION OF AVERAGE MONTHLY TEMPERATURE SINCE THE TWO MISSING DAYS WERE VERY WARM. USING REASONABLE ESTIMATIONS FOR THE TWO MISSING DAYS WOULD GIVE AN AVERAGE MONTHLY TEMPERATURE OF 71.3 DEGREES, 2.8 DEGREES ABOVE NORMAL AND THE WARMEST SINCE 2001. THE WARMEST AUGUST ON RECORD WAS 1872 WHEN THE AVERAGE TEMPERATURE WAS 73.6 DEGREES. THE COOLEST WAS 1903 AT ONLY 61.1 DEGREES. A TOTAL OF 5.56 INCHES OF RAIN FELL WHICH WAS 2.38 INCHES ABOVE NORMAL ALMOST HALF (2.48 INCHES) OF THE MONTHLY TOTAL FELL IN JUST A FEW HOURS ON THE EVENING OF THE 18TH. ANOTHER 1.60 INCHES FELL A WEEK LATER ON THE 25TH. THE WETTEST AUGUST ON RECORD WAS 1892 WHEN 9.00 INCHES OF RAIN FELL. THE DRIEST WAS 1996 WHEN ONLY 0.06 INCHES WAS MEASURED. TWO SEPARATE INCIDENTS OF EQUIPMENT FAILURE LED TO ESTIMATED OR MISSING DATA AT CONCORD. THEY ARE DETAILED BELOW. DATA WAS LOST ON THE EVENING OF AUGUST 11. PRECIPITATION WAS OCCURRING AT THE TIME AND HAD ACCUMULATED TO 0.74 INCHES BEFORE DATA WAS LOST. AN ADDITIONAL 0.10 INCHES IS ESTIMATED TO HAVE FALLEN AFTER THE EQUIPMENT FAILURE, BASED ON NEARBY OBSERVATIONS. THIS LED TO THE ESTIMATED VALUE OF 0.84 INCHES ON AUGUST 11. DATA WAS LOST ON THE EVENING OF AUGUST 18 AFTER A THUNDERSTORM. THE PRECIPITATION AND TEMPERATURE DATA FOR AUGUST 18 WAS NOT AFFECTED, HOWEVER, DATA WAS NOT RESTORED UNTIL THE MORNING OF AUGUST 21. THE LOW TEMPERATURE ON AUGUST 21 WAS ESTIMATED AT 65 DEGREES BASED ON NEARBY OBSERVATIONS. THE DATA ON AUGUST 19 AND 20 WAS LOST DUE TO THE OUTAGE. BASED ON NEARBY OBSERVATIONS IT IS REASONABLE TO CONCLUDE THAT CONCORD HAD A HIGH OF 91 AND A LOW OF 64 ON AUGUST 19 AND A HIGH OF 88 AND A LOW OF 64 ON AUGUST 20. USING THESE ESTIMATES THE AVERAGE MONTHLY TEMPERATURE WOULD HAVE BEEN 71.3 DEGREES, WITH 5 DAYS ABOVE 90 DEGREES. THERE WERE NO DAILY RECORDS SET OR TIED DURING AUGUST 2015. $$ KIMBLE
