...JUNE HIGHLIGHTS...
...RECORD EARLY START TO THE MONSOON...
...2ND WETTEST JUNE ON RECORD...
...LIGHTNING SPARKS WILDFIRES IN THE SURROUNDING MOUNTAINS...

THE SECOND WETTEST JUNE ON RECORD...THANKS IN PART TO THE EARLIEST
START OF THE ANNUAL SUMMER THUNDERSTORM SEASON...WAS THE BIG STORY FOR
JUNE. 
		
THE MONTH BEGAN VERY WARM WITH TEMPERATURES ABOVE THE CENTURY MARK
FOR THE FIRST WEEK. SOME MOISTURE BEGAN TO MOVE ACROSS THE AREA DURING
THIS PERIOD WHICH DEVELOPED DRY LIGHTNING THUNDERSTORMS OVER THE
SURROUNDING MOUNTAINS. THIS SPARKED A WILD FIRE IN RATTLESNAKE CANYON
OF THE SANTA CATALINA MOUNTAINS ON THE 9TH WHICH LASTED AROUND A WEEK.
AFTER SEVERAL DAYS OF BELOW NORMAL TEMPERATURES BETWEEN THE 8TH AND 
11TH...TEMPERATURES ABOVE THE CENTURY MARK RETURNED BETWEEN THE 12TH
AND 16TH. 

A DRAMATIC INCREASE IN MOISTURE ON THE 17TH...THANKS IN PART TO THE
REMAINS OF TROPICAL STORM BUD...BROUGHT THE FIRST WETTING RAINS TO THE
AREA SINCE MARCH 27TH. THE AVERAGE DAILY DEWPOINT VALUE OF 45 DEGREES
ON THE 16TH ROSE TO 61 DEGREES AND REMAINED ABOVE 54 DEGREES FOR THE
NEXT TWO DAYS. THUS THE ANNUAL MONSOON BEGAN ON THE 17TH WHICH IS THE
EARLIEST ON RECORD...DATING BACK TO 1965. THUNDERSTORM ACTIVITY CONTINUED
THROUGH THE END OF THE MONTH. THE BIGGEST STORM OF THE MONTH OCCURRED ON
ON THE EVENING OF THE 29TH...WHEN VERY HEAVY RAINFALL IN A SHORT PERIOD
OF TIME LED TO FLASH FLOODING EXTENDING FROM DOWNTOWN TO THE EAST SIDE.
MONTLY RAINFALL TOTALS AROUND THE METRO AREA RANGED FROM ONE TO TWO AND
A HALF INCHES WITH SOME LOCAL SPOTS RECORDING OVER THREE INCHES OF RAIN.
OFFICIALLY THE TUCSON INTERNATIONA AIRPORT RECORDED 1.56 INCHES OF RAIN
WHICH RANKS AS THE SECOND WETTEST JUNE ON RECORD. IN FACT...THIS TOTAL
EXCEEDS THE COMBINED TOTAL OF JUNE RAINFALL FROM 1989 TO 1999. SEVERAL
RAINFALL RECORDS WERE SET OR TIED IN JUNE:
		
THE MOST NUMBER OF DAYS WITH RECORDED RAINFALL....
		12 DAYS (OLD RECORD 11 DAYS IN 1972)
THE MOST NUMBER OF DAYS WITH MEASURABLE RAINFALL....
		9 DAYS (TIED RECORD OF 9 DAYS SET IN 1972)

THE RAINFALL TOTAL OF 0.58 INCHES ON THE 19TH WAS THE NINTH WETTEST
DAY ON RECORD FOR JUNE. THE ABUNDANT JUNE RAINFALL HELPED PUSH THE
YEARLY TOTAL TO JUST BELOW NORMAL. HOWEVER...THE WATER YEAR DEFICIT
CONTINUES WITH THE TOTAL RAINFALL NOW THREE INCHES BELOW NORMAL.		
		
THE INCREASE IN MOISTURE DURING THE SECOND HALF OF THE MONTH KEPT
HIGH TEMPERATURES BELOW NORMAL AND LOW TEMPERATURE ABOVE NORMAL.
OVERALL THE MONTH END JUST UNDER ONE DEGREE ABOVE NORMAL WITH AN
AVERAGE MONTHLY TEMPERATURE OF 84.6 DEGREES. TEMPERATURE EXTREMES
