..JULY 2018 CLIMATE SUMMARY FOR JACKSONVILLE
 
 
   
..STORMIEST JUNE-JULY FOR JACKSONVILLE ON RECORD
 
 
SUMMARY...JULY WAS A VERY BUSY MONTH IN TERMS OF DAILY CONVECTION AS  
JACKSONVILLE BROKE IT'S ALL TIME RECORD FOR NUMBER OF DAYS WITH  
STORMS REPORTED. BETWEEN JUNE AND JULY, JACKSONVILLE INTERNATIONAL  
AIRPORT REPORTED STORMS ON 47 OUT OF 61 DAYS. THE PREVIOUS RECORD  
FOR THIS TIME PERIOD WAS 45 DAYS SET IN PREVIOUS YEARS OF 1924,  
1927, AND 1971. ALTHOUGH THE AREA SAW NUMEROUS STORMS, THE 8.86  
INCHES IN PRECIPITATION FOR THE MONTH RANKED A SURPRISING 33RD  
WETTEST. OUT OF 20 DAYS OF MEASUREABLE RAINFALL, ONLY 6 DAYS  
OBSERVED A HALF INCH OR MORE, AND MANY DAYS SAW A QUARTER INCH OR  
LESS. SO DESPITE THERE BEING A RECORD STORMY PATTERN, THE RECORD  
PRECIPITATION DID NOT FALL; HOWEVER, THE AREA STILL SAW SEVERAL  
INCHES ABOVE JULY NORMALS. THE RECORD NUMBER OF THUNDERSTORMS DAYS  
WAS NOT ISOLATED TO JAX. GAINESVILLE ALSO BROKE THEIR LOCAL RECORD  
FOR NUMBER OF THUNDERSTORM DAYS WITH 51 OF 61. THE PREVIOUS RECORD  
WAS 47. SIMILAR TO JACKSONVILLE, GAINESVILLE ONLY SAW 4 DAYS WITH  
OVER A HALF INCH OF OBSERVED PRECIPITATION, AND IF HADN'T BEEN FOR  
THE 2.25 INCHES THAT FELL ON THE 22ND OF THE MONTH, GNV COULD HAVE  
TECHNICALLY SEEN BELOW AVERAGE PRECIPITATION FOR THE MONTH. LOOKING  
OVER THE AREA AS A WHOLE, THIS WOULD NOT HAVE BEEN REPRESENTATIVE OF  
THE ACTUAL RAINFALL SEEN. OTHER OBSERVATIONS STATIONS IN THE AREA,
