Few Sprinkles Here



View of Catalinas and north part of Tucson above at 7:10 am MST this early morning, showing heavy clouds overhead. Skies now are clearing with bright sunshine. Here at house there has apparently been a light sprinkle, since the newspaper had a few drops on it when I brought it in. Down at the bottom are views of clouds massing on Kitt Peak and also of sunset colors yesterday evening.

Only a few sites in the northwest part of metro have reported measurable rain as of about 8:00 am -  below from MesoWest. There was a skiff of light snow in Summerhaven this morning. 

All in all not much of an event, other than yesterday's strong winds. Almost all the observing sites in southeast Arizona reported wind gusts over 30 mph yesterday afternoon. Guthrie RAWS and Pioneer Airfield had gusts to 51 mph; Empire RAWS had 44 mph; TUS and Marana had 41 mph; and Canelo RAWS reported 40 mph.


The 06 UTC GEFS plumes for QPF at the airport (above) indicate light showers through the day. However, both the 06 UTC WRF forecasts below (top GFS version and second RR version for total precipitation through noon tomorrow) indicate that the event has basically ended for most of the greater Tucson area. Up to this time none of the model forecasts for last couple of days have handled this event very well.
