Showers continue around metro early this morning - above is composite radar at 05:10 am MST on the last day of 2016.
The ALERT network seems to be functioning now, and I've broken the new display into a north and a south portion to show rainfall through 05:00 am. Overnight measurable rain has occurred over 100 % of the ALERT area and also the Tucson metro region. Amounts at low elevations generally a tenth to a third of an inch so far (0.27" here at house), but with much higher amounts over and around the Catalinas and Rincons. This first event has been mostly rain, even at high elevations.
The WRF forecasts from atmo indicate continued chances today for light showers around the region, followed by the second colder and again widespread event tomorrow. Significant snowfall forecast at high elevations of the Sky Islands tomorrow, with much cooler temperatures at low elevations. Definitely a nice transition to 2017 for weather watchers.
