Fast hitting squall line moved across much of south-central and southeast Arizona yesterday afternoon - view above shows the dismal conditions on U of A campus at 4 pm. Here at house temperature briefly dropped to 40F during the rain and winds gusted over 40 mph. Brief burst of rain left 0.12" in the gauge. I see a report of 80mph+ winds in Apache Junction east of Phoenix, Guthrie RAWS had gust to 62 mph, Atmo roof top anemometer hit 58 mph, and Safford recorded a gust to 56 mph - gusts of 30 to 50 mph were common at many of the RAWS sites. Looks like about 75 to 80% of the Pima County ALERT gauges had measurable precipitation but with amounts at lower elevations mostly from 0.04" to 0.15". So, it turns out that 30 to 50% POPs were a bit conservative for metro Tucson area. Quite a wild winter/spring continues with several more S/Ws at 500 mb forecast to swing by, or through, southeast Arizona during the next seven days!

The NWS radar and ASOS systems remain out of service. Latest status message says that perhaps radar will be back in service by this afternoon (Wednesday Mar 10th).

At sunrise here at house this morning - a very frosty 27F for a low.
