View of heavy thunderstorm over north portion of city from downtown at 3:10 pm MST yesterday.
Plot of detected CG flashes from Atmo and Vaisala (above) is for 24 hours ending at 0803 UTC last night - note that flashes were concentrated over the north portion of eastern Pima County. Time series of T and Td (below) from Atmo shows the dramatic temperature drop as the rainfall began.
ALERT data (above and below) indicate that rainfall was also concentrated over the west to north parts of the metro area with heaviest amounts extending from southwest across the metro area to the Catalinas. Here at house we had 1.39" in the gauge. The airport reported 0.37" and DM had a Trace; however Atmo came in with 2.06"! Angel Otarola reported right at 3 inches from his location a couple of miles east of here.
Sounding this morning from TWC/TUS (above) shows a classic, post-storm, onion shape. It will be very hard for the dry, sub-cloud layer to mix out today. The forecast from the 12 UTC run of the WRF-RR at Atmo (below) shows eastern Pima County mostly dry through 6:00 am tomorrow morning.
When’s the last time you had over 1.39 in. at your location?
