...JUNE HIGHLIGHTS...
...ABOVE NORMAL TEMPERATURES WITH LITTLE OR NO RAINFALL...
...MAGICAL 1ST 100 DEGREE HIGH OF 2004 OCCURS ON THE 1ST...


THE MAJORITY OF JUNE WAS DOMINATED BY AN UPPER LEVEL TROUGH TO THE
WEST AND HIGH PRESSURE TO THE SOUTH AND EAST. EXCEPT FOR A COUPLE OF
DAYS DURING THE EARLY PART OF THE MONTH...HIGH TEMPERATURES WERE
NEAR NORMAL. DAILY LOW TEMPERATURES WERE ABOVE NORMAL FOR THE MONTH
WHICH RESULTED IN THE AVERAGE MONTHLY TEMPERATURE BEING ABOVE NORMAL.

THE MONTH STARTED OFF WITH THE TUCSON AREA FINALLY REACHING THE
MAGICAL 100 DEGREE MARK AT 2:00 PM ON THE 1ST. THIS MARKED THE FIRST
TIME SINCE 1998 (JUNE 1) AND ONLY THE SECOND TIME SINCE 1987 (JUNE 2)
THAT TUCSON HAD TO WAIT UNTIL JUNE TO RECORD THE FIRST 100 DEGREE
HIGH FOR THE YEAR. THE FIRST HEAT WAVE OF 2004 CONTINUED THROUGH THE
6TH WITH DAILY HIGH TEMPERATURES BETWEEN 104 AND 107 WERE RECORDED.
THE REMAINDER OF THE MONTH...DAILY HIGH TEMPERATURE WERE RELATIVELY
COOL FOR TUCSON STANDARDS AND PAST YEAR WITH A FEW DAYS (14TH/26TH
AND 27TH) WHERE THE HIGHS WERE EITHER 103 OR 104. OVERALL THE
AVERAGE MONTHLY TEMPERATURE OF 84.8 DEGREES WAS 0.7 DEGREES ABOVE
NORMAL AND THE COOLEST SINCE JUNE 2000.

2004 ..... 84.8     1999 ..... 83.8
2003 ..... 85.7     1998 ..... 81.8

2001 ..... 85.5     1996 ..... 87.4
2000 ..... 84.6     1995 ..... 83.3


TEMPERATURE EXTREMES FOR THE MONTH RANGED FROM A HIGH OF 107 DEGREES
ON THE 4TH TO A LOW OF 58 DEGREES ON THE 10TH.


A LITTLE BIT OF MONSOON TYPE MOISTURE STARTED TO WORK ITS WAY TOWARD
SOUTHERN ARIZONA DURING THE LATER TEN DAYS OF THE MONTH. HOWEVER THE
MOISTURE WAS RATHER LIMITED AND RESULTED IN MAINLY DRY THUNDERSTORMS.
HOWEVER...THERE WERE SOME ISOLATED SPOTS AROUND THE METRO AREA THAT
DID RECORD UP TO A QUARTER OF AN INCH OF RAIN FOR THE MONTH.
OFFICIALLY THE AIRPORT RECORDED ONLY A TRACE OF RAIN...WITH RAIN
BEING RECORDED AT THE AIRPORT ON THE 22ND..23RD AND 29TH. THE MONTH
ENDED WITHOUT A CLOUD IN THE SKY SINCE THE TROUGH TO THE WEST HAS
KEPT MONSOONAL MOISTURE BOTTLED UP IN MEXICO...SOUTH OF MEXICAN
STATES OF SONORA AND CHIHUAHUA.
