...JULY WAS VERY SOGGY IN JUNUEAU...

LEAVING A WETTER THAN NORMAL JUNE BEHIND...THE HOPES FOR WARM AND DRY
JULY IN JUNEAU HAD MIXED RESULTS. RAIN AT THE START OF THE MONTH GAVE
WAY TO A 4 DAY STRETCH OF WARM AND DRY CONDITIONS THAT BEGAN ON THE
IDEPENDENCE HOLIDAY BEFORE THE RAINS RETURNED. THOSE 4 DAYS WERE THE
MAJORITY OF DRY DAYS IN THE MONTH AS IT PROCEEDED TO RAIN 21 OF THE
NEXT 24 DAYS. MEASURABLE RAIN FELL ON 24 OF THE 31 DAYS DURING THE
MONTH WITH 7 DAYS REPORTING MORE THAN 1/2 INCH OF RAIN. NORMALLY...ONLY 3
DAYS IN JULY SEE 1/2 INCH OF RAIN OR MORE.

THIS PAST JULY WAS THE WETTEST ON RECORD FOR JUNEAU WITH 10.40 INCHES OF
RAIN RECORDED AT THE AIRPORT. THIS TOPS THE OLD RECORD FROM 1997 BY 0.04
INCHES. IN SPITE OF THE RECORD MONTHLY RAINFALL...ONLY ONE DAILY RECORD FOR
RAIN WAS BROKEN DURING THE MONTH. ON JULY 23 THE OLD RECORD OF 1.14 INCHES
WAS SHATTERED WHEN 2.00 INCHES WAS RECORDED AT THE AIRPORT.

THE AVERAGE TEMPERATURE WAS JUST UNDER A DEGREE WARMER THAN NORMAL
WHICH RANKED IT IN THE TOP 15 WARMEST ON RECORD FOR THE MONTH. THE
ABOVE NORMAL AVERAGE TEMPERATURE WAS A RESULT OF THE WARM LOW
TEMPERATURES DURING THE MONTH THAT RANKED THE 3RD WARMEST ON RECORD.
THE DAYTIME HIGHS WERE HAMPERED BY SIGNIFICANT CLOUD COVER DURING THE
MONTH. HOWEVER...OF THE 7 DRY DAYS...5 OF THEM SAW DAYTIME HIGHS OVER  70
DEGREES...INCLUDING A TOASTY 84 DEGREES ON THE 6TH.
