From the Thursday 3 a.m. Phoenix forecast discussion: BY FRI HIGH PRESSURE CENTERED IN MEXICO WILL WILL BUILD NORTH INTO AZ AND CONTINUE THROUGH SAT. THIS WILL BRING MOSTLY CLEAR SKIES TO OUR REGION. HOWEVER...BY FRI NIGHT/SAT AS THE RIDGE BUILDS AND FLOW BECOMES SW...SOME MID/HI CLOUDS WILL BEGIN TO FILTER INTO OUR REGION. The Environment Canada cloud and transparency maps show a thin band of clouds passing through the All-AZ star party site from the southwest in agreement with the NWS forecast. This is followed by a period of good transparency, with intermittent high clouds thereafter. Right now it looks like Friday may be the better night, but neither of them look stellar.
