Pre-sunrise colors looking toward Redington Pass at 5:30 am MST this morning.
Plot of CG flashes detected through 0733 UTC (1233 am) shows no flashes in eastern Pima County - above from Atmo and Vaisala. However, plot of ALERT rainfall observations shows light amounts scattered here and there though 8:00 am this morning (below - both north and south portions of the network). Here at house it appears that there was an early morning sprinkle.
The morning upper-air sounding from TWC/TUS (above) is nearly saturated above 600 mb, but lower levels are much drier and chopped up. Winds are easterly below 300 mb, with some speeds just over 20 kts. CAPE is quite limited.
The 12 UTC WRF-RR forecast for precipitation though noon tomorrow (above) shows a Tucson donut hole - ugh.
