More Wind Today

Views looking north along I-10 near Marana: above is from a bit before 6:00 am MST this morning - note the Palo Verde tress in full bloom in median and west side of highway. This is a very "yellow" time of year here in Arizona. Bottom is from yesterday at about 11:00 am, showing blowing dust to the north - you can just make out Picacho Peak west of Interstate in distant north.

It was quite windy yesterday - observations below from airport indicate gusts of 25 to 35 mph through most of the day.

The southern end of a 500 mb short wave (12 UTC analysis above) that extends from the Great Basin south along western border of Arizona will swing northeastward across the state today. This will keep the gusty winds going - 06 UTC WRF-GFS forecast for 10-m winds - below - is valid at 3:00 pm this afternoon. When I walked a bit before 8:00 am this morning, winds were already gusting 20 to 25 mph along the Rillito.
