More Wind Today


Sunrise this morning as viewed from Sahuarita, which is south of Tucson. Down at bottom is image of large, lenticular cloud over the San Francisco Peaks at 6:20 am MST this morning.

Only some light sprinkles during the morning yesterday, and so total rainfall here was just 0.05".

Wind and dust advisories (above) as issued by TUS NWS this morning - forecast for the airport calls for gusts 40 to 45 mph this afternoon. Below is 06 UTC WRF-GFS forecast for steady wind speeds at 5:00 pm this afternoon, indicating strong winds across much of Arizona. 

The air quality advisory in eastern Pinal County is a bit of a mystery, since there is no mention of this in the early am forecast discussion. I assume that it relates to dust concentrations expected due to the winds weakening as they approach the higher terrain north of the Catalinas.


This morning's forecast for the airport also includes a chance for showers on Friday night, as do the 06 UTC GEFS plumes shown below. A bit more rain would be welcome, but I am certainly tired of the winds recently, since they make morning walks much less pleasant.
