THE MORNIN OF OCTOBER 1ST...A SPAN OF 153 DAYS. THIS LENGTH OF TIME
SURPASSED THE PREVIOUS RECORD OF 146 DAYS SET BACK IN 1940.


THE DRY MONSOON...

AN UNUSUAL LARGE SCALE PATTERN DISRUPTED THE NORMAL FLOW REGIME THAT WOULD
ALLOW MONSOON MOISTURE TO BE PUSHED ACROSS ARIZONA FROM JULY THROUGH SEPTEMBER.
ARIZONA WOULD EITHER EXPERIENCE DRY SOUTHWEST FLOW...OR BE LOCATED UNDERNEATH
A CAPPING SUBTROPICAL RIDGE MOST OF THE TIME. THIS RESULTED IN MUCH BELOW
AVERAGE PRECIPITATION FOR THE TYPICAL JUNE 15TH THROUGH SEPTEMBER 30TH
MONSOON SEASON ACROSS NORTHERN ARIZONA.
