Showers And Strong Winds This Afternoon

A band of convective showers (ahead of the short wave/vorticity maximum moving across southern Arizona) is moving across the Tucson metro area. Radar and view of Catalinas above are from around 4 pm MST. The showers produced a strong outflow and sharp temperature drop here at house - estimate brief gusts to 40 to 45 mph. The time series below (from Atmo) show the temperature drop and also indicate gusts to 70 mph on the roof of the Atmo building. Only a trace of rain here, but definitely a nasty end to the afternoon.
