First Precipitation Of 2022

View of Catalinas with band of sunshine along the foothills yesterday afternoon at 4:50 pm MST. Down at bottom is east view from San Simon at about 7:00 am this morning.


ALERT network 24-hour rainfall at 7:30 am this morning (north half above and south below) - remember that ALERT only reports amounts of 0.04" or greater. Data from MesoWest indicates that almost 100% of reporting gauges in the metro area had a Trace or more.

The airport reported 0.04", DM had 0.05", and here at house I measured 0.18". So with respect to yesterday's forecasts: the GEFS plumes were quite good; the NWS forecast was a bit conservative; and the WRF-GFS had the precipitation shifted east of the metro area.
