GRADUALLY, THOUGH, MORE DRY AIR BEGAN MOVING INTO THE AREA ALONG WITH SOME COOLER TEMPERATURES. THE SUMMER WARMTH RETURNED FOR THE MIDDLE OF THE MONTH, WHEN CONCORD ENDURED A WEEK OF SUSTAINED WARMTH INCLUDING 3 STRAIGHT DAYS OF 90 DEGREES FROM THE 19TH THRU 21ST. THE SUMMER HEAT BROKE WHEN A COLD FRONT CAME THROUGH ON THE 23RD, BRINGING SIGNIFICANTLY COOLER WEATHER. JUST A FEW DAYS AFTER HITTING 90 DEGREES, CONCORD SAW A HIGH OF ONLY 61 DEGREES ON JULY 24 ALONG WITH SOME RAINFALL. THIS WAS THE COLDEST JULY HIGH TEMPERATURE IN 25 YEARS (SINCE JULY 4, 1992). THE COOLER THAN NORMAL WEATHER CONTINUED THROUGH MUCH OF THE REST OF THE MONTH. THE AVERAGE TEMPERATURE FOR JULY WAS 70.0 DEGREES WHICH IS THE NORMAL VALUE FOR THE MONTH AND THE COOLEST JULY SINCE 2009. THE COLDEST JULY WAS IN 1969 WHEN THE AVERAGE TEMPERATURE WAS 65.4 DEGREES. THE WARMEST WAS IN 1872 WHEN THE AVERAGE TEMPERATURE WAS 75.2 DEGREES. A TOTAL OF 1.21 INCHES OF PRECIPITATION FELL WHICH WAS 2.53 INCHES BELOW NORMAL AND THE 8TH DRIEST JULY ON RECORD. THE HEAVIEST PRECIPITATION FELL ON THE 24TH WHEN JUST UNDER HALF AN INCH OF RAIN WAS OBSERVED. THE DRIEST JULY ON RECORD WAS IN 1910 WHEN ONLY 0.91 INCHES OF RAIN FELL. THE WETTEST WAS IN 1915 WHEN 10.29 INCHES FELL. THE FOLLOWING TABLE LISTS THE DRIEST JULYS ON RECORD AT CONCORD. LEAST PRECIPITATION IN JULY AT CONCORD (1868 TO PRESENT)...
