The above plot of CG flashes (from Atmo and Vaisala) is for 12-hours ending at 03 UTC (8:00 pm MST) last evening. Although there were reports of light rainfall at higher elevation stations, I could find only one lonely Arizona flash down in the Santa Ritas.
The convective system that went west to the GoC has triggered a strong, low-level moisture surge across the Yuma area this morning - between 4:00 and 5:00 am dewpoints jumped from the 50s into the 70s. The Yuma radar VAD indicates the surge reaches only to about 2,000 ft MSL. But, the thermal structure and inversion related to the surge has resulted in extreme ground clutter due to ducting - some of this is "fooling" operational rain-estimation, algorithms this morning.
Note the large cluster of detected flashes at the south end of Baja.
Luis Farfan sent these images yesterday evening. The huge storm in photo is west-southwest of La Paz at about 6:00 pm. Note that the rain appears to be extremely heavy and is producing a wet macroburst - definite outflow "foot" to left side of storm. An IR image of this event, below from about 5:00 pm, shows the intense convection was centered over the spine of Baja. Thanks to Luis for the images!
