Yesterday afternoon winds were gusting in the mid-to-upper 20 mph hour range. There remains some suspended dust in the air, giving us skies that are a bit dirty at sunrise (above).
The 500 mb pattern at 12 UTC (above) remains strongly blocked over the U.S., but the western trough is slowly pushing inland. The winds aloft here will increase a bit more, as the southern end of the trough swings slowly across Arizona (500 forecast below from 06 UTC GFS is valid at 12 UTC tomorrow).
The 06 UTC WRF-GFS forecast for today (above is valid at 2:00 pm MST this afternoon) indicates strong, south-southwesterly winds impacting much of Pima County - gusts will likely be up above 30 mph today.
Below is unwrapped am view from Mt. Lemmon SkyCenter - very pristine air up there, and the camera lens has been cleaned!
