...JUNE HIGHLIGHTS...
...3RD WARMEST AND 19TH WETTEST ON RECORD...
...RECORD RAINFALL SET ON JUNE 6TH...
...2006 SUMMER THUNDERSTORM SEASON BEGAN ON JUNE 28TH...

THE 2005-2006 DROUGHT CONTINUED THROUGH ITS TENTH MONTH WITH MOTHER
NATURE BRINGING A MONSOON TEASER DURING THE FIRST WEEK OF JUNE AND
THEN OFFICIAL START TO THE SUMMER THUNDERSTORM SEASON AT THE END OF
THE MONTH.

ATMOSPHERIC CONDITIONS DURING THE FIRST SEVEN DAYS OF THE MONTH
RESEMBLED A MONSOON LIKE PATTERN WITH HIGH PRESSURE NEAR THE FOUR
CORNERS REGION AND SOME MOISTURE SEEPING INTO SOUTHEAST ARIZONA.
HOWEVER...THIS MOISTURE WAS LIMITED TO THE MID LEVELS OF THE
ATMOSPHERE WITH THE LOWER LAYERS NEAR THE SURFACE BEING VERY DRY.
THUS ANY THUNDERSTORM ACTIVITY THAT DEVELOP WOULD PRODUCE VERY STRONG
DOWNBURST WINDS AND VERY BRIEF HEAVY RAIN. WITH THE GROUND BEING VERY
DRY DUE THE PROLONGED DROUGHT...THE DOWNBURST WINDS WOULD PRODUCE
DUST STORMS. ON FRIDAY JUNE 2ND...A MICROBURST HIT THE SOUTHEAST SIDE
OF TUCSON AND KNOCKED DOWN ABOUT A DOZEN POWER POLES AT CAMINO SECO
AND PANTANO ROADS. ON SATURDAY JUNE 3RD...ANOTHER MICROBURST HIT THE
CITY...PRODUCING A DUST STORM AND ALSO KNOCKING DOWN POWER POLES AT
ALVERNON AND PALO VERDE. THE INTERNATIONAL AIRPORT MEASURED A WIND
GUST OF 56 MPH FROM THE MICROBURST. AFTER A QUIET SUNDAY JUNE
5TH...MOTHER NATURE DEVELOPED HER STRONGEST STORM OF THE MONTH. THIS
MICROBURST HIT THE SOUTH AND WEST SIDES OF TUCSON AND DOWNED POWER
POLES NEAR THE INTERNATIONAL AIRPORT...IN DOWNTOWN TUCSON AND ALSO IN
MARANA ALONG INTERSTATE 10 AT THE TANGERINE ROAD EXIT. GOLFBALL SIZE
HAIL FELL IN MARANA AND DUE TO WIND GUSTS NEAR 60 MPH...A DUST STORM
DEVELOPED ON THE WEST SIDE AND MOVED THROUGH MARANA WHICH EVENTUALLY
HIT THE PHOENIX AREA AND MAKE NATIONAL NEWS. THIS STORM WAS ALSO A
BIT WETTER THAN THE ONES THAT OCCURRED ON THE 2ND AND 3RD. THE
AIRPORT RECORDED SLIGHTLY MORE THAT ITS NORMAL JUNE RAINFALL IN
THIRTEEN MINUTES BETWEEN 3 AND 4 PM WHEN 0.27 INCHES FELL. OFFICIALLY
FOR THE 6TH...SLIGHTLY UNDER A THIRD OF AN INCH /0.31"/ WAS RECORDED
AT THE AIRPORT...WHICH BROKE THE DAILY RECORD OF 0.08 INCHES...WHICH
WAS SET IN 1987...AND WAS ALSO THE MOST RAIN IN ONE DAY SINCE AUGUST
23RD.

HIGH PRESSURE RE-ASSERTED ITSELF ACROSS THE STATE OVER THE NEXT TWO
PLUS WEEKS AND PUSHED MOISTURE OUT OF THE AREA. THUS MORE TYPICAL
JUNE TYPE WEATHER WITH AFTERNOON HIGH TEMPERATURES FROM THE UPPER 90S
TO 107 DEGREES. OVERNIGHT LOW TEMPERATURES WERE ALSO WARM WITH THREE
DAYS (20TH /80F/...21ST /81F/ AND 24TH /82F/) NOT SEEING THE MERCURY
DIP BELOW 80 DEGREES.

ATMOSPHERIC CONDITIONS DURING THE LAST SEVEN DAYS OF JUNE STARTED TO
RESEMBLE MONSOONAL LIKE FLOW...WHICH ALLOWED MOISTURE FROM MEXICO TO
MOVE NORTH INTO SOUTHERN ARIZONA. AVERAGE DAILY DEWPOINT VALUES MOVED
INTO THE UPPER 40S AND LOWER 50S. FINALLY ON JUNE 28TH...THE DAILY
AVERAGE DEWPOINT ON THE 28TH WAS AT OR ABOVE 54 DEGREES AND MAINTAINED
THAT LEVEL THROUGH THE 30TH. THUS THE 2006 SUMMER THUNDERSTORM SEASON
OFFICIALLY STARTED ON THE 28TH. THIS MARKED THE FIRST TIME SINCE 2000
THAT THE START DATE FELL IN JUNE.
