Update

 

View of the Rincons around 6:30 am MST this morning.

There was no more rain yesterday after the morning post, so total for the event here was 0.27". This was the most rain since the 0.34" on January 23rd and 24th.

Lingering Showers

Heavy clouds over Tucson and the Catalinas at 8:00 am MST this morning. Image at bottom shows a snippet of a rainbow at 4:00 pm yesterday afternoon.

Considerable CG flashes with the storms yesterday late - plot of flashes above for 24-hurs ending at 0833 UTC early this morning (from Atmo). There were several crashes of thunder here around 4:00 pm.

Rain amounts of 0.04" or more occured at almost all of the ALERT sites during the 24-hours ending at 9:30 am this morning (above and below), with greatest amounts out west of here along the Interstate. We had 0.27" in the gauge this morning.

Radar base-scan from 9:30 am (above) indicates a few lingering showers over eastern Pima County. These are moving to the southwest, as the upper low is centered south of Tucson. Current forecast from the NWS (below) for the airport indicates a rapid warm-up after today's unsettled weather.

Showers Today and Tonight

Clear skies looking toward the Rincons a bit before 7 am MST this morning.

The 06 UTC GEFS plumes for QPF at airport (above) indicate showers late today, continuing through the night. Average amounts are around 0.30". 

Plumes for temperature (above) indicate a rapid cool down for tomorrow, followed by a rapid rebound to very warm temperatures. The GEFS POPs hit 100 percent during the night (below).

Current morning forecasts from the NWS (above and below) indicate POPs at the airport reaching 90 percent tonight. Last rainfall here at house was well over two weeks ago, so some rain would be much appreciated.
