High Overcast, Dirty Skies And Mild Temperatures


View of Catalinas at 8:20 am MST above shows high cirrus overcast and skies a bit dirty with dust from the east. Winds are currently gusting over 30 mph at the airport. Morning temperatures have been quite mild with a low so far at the airport of only 52 F - here at house temperature had dropped to 41 F before the winds broke through. MesoWest surface plot at 6 am (below) shows mild temperatures across the Tucson area and gusty east winds at many locations. The WRF forecast models run at Atmo yesterday forecast the winds and temperatures quite well for this morning.


An upper-level short wave is moving north just west of Baja (IR image from 13 UTC below) with widespread cloudiness associated with it, including the cirrus currently over Tucson - note that airport ASOS indicates clear skies since the system does not detect higher clouds.
