Early Morning Storms For Tucson Metro

Storms rumbled into town just before sunrise this morning and moved rapidly on to the west. The Kitt Peak web cam (looking north a bit after 6 am MST) caught a lightning flash. NWS TUS radar composite image at 4:47 am is below. Heaviest cores and rain tracked nearly along I-10 from east of Benson across metro Tucson and then went west into the hinterlands.

Plot of CG flashes (above for 24-hours ending at 6 am MST) shows track of the early morning storms in red to purple to white dots. The storms seemed to develop around Texas Canyon, perhaps along an outflow off the Chiricahuas.

Heaviest rains show nicely on these ALERT plots (above metro and east sector and below metro and west sector) for  6 hour rain amounts ending at 6:30 am. Note other amounts not on the plot - DM AFB 1.10"; NWS at airport 0.75"; Atmo 0.31"; and here at north edge of event 0.14". Bottom is photo of trailing light rain at sunrise.
