Continued Wet

Periods of showers and some thunder continue to be the story for this week. Catalinas obscured by rain yesterday at 11:00 am MST (above).

Composite radar at 6:53 am this morning (below) shows showers to the south moving toward eastern Pima County.

Yesterday thunderstorms avoided the lower elevations, with recent storms occurring along the western Cochise County line (CG flashes above (from Atmo and Vaisala are for 24-hours ending at 5:53 am this morning).

ALERT rainfall reports (above and below for 24-hours ending at about 7:00 am this morning) show essentially 100 percent areal coverage with numerous reports of greater than an inch, with amounts having distinct east to west gradient. (There are two sites that appear to be out-of-order.)

We had 0.69" here, which pales in comparison to the 2.37" that Art Douglas reported at 6:00 pm yesterday afternoon. Regardless, a very wet day for much of southeastern Arizona.

The 500 mb closed low is off to our west-southwest this morning (analyses above and below from SPC) over GoC and Baja. The low will move northeastward later today and tomorrow, bringing the rainy period to an end by Friday.

Our morning upper-air sounding is nearly saturated (PW of around 1.50 inches). There is still a sliver of CAPE and strong southerly winds through most of troposphere. Looks favorable for continued rainy periods!
