July Summary

 

Storms on Catalinas at 5:40 pm on July 16th.

Rainfall during July totaled 1.09" - this was the fifth driest July here since 1999. There was measurable rain on 7 days. There were two days when I estimated gusts of 40 to 50 mph with the storms.

Scattered Showers

Catalina sunrise view at 5:40 am MST this morning. Lightning flashes east of Rincons occurred around 4:00 am (bottom).

Numerous CG flashes detected through 1303 UTC (below) and ALERT reports (above) avoided main metro area and region north of Catalinas. Airport reported a gust to 48 mph and a Trace; DM reported thunder and a gust to 30 and Atmo reported a gust to 30 mph - all around midnight. Perhaps a Trace and thunder here but can't verify this.

Dry Spell Continues

Golden skies over the Rincons at 5:00 am MST this morning.

Another very suppressed day yesterday as shown by dearth of activity over southeast Arizona: above detected CG flashes through 0903 UTC from atmo, and absence of any reports across the entire ALERT Network below.

Plumes for QPF at the airport (above, from o6 UTC runs) shows slight chances for showers tonight and later in week. The POPs for TUS from same runs (below) reach 40 to 50 percent for several periods through early next week. Current forecast from NWS indicates 30 percent POPs for airport tonight and then no mention of showers again through Friday.

IR image from 1440 UTC (below) shows the two hurricanes in eastern Pacific: Cat 1 Fausto left heading toward Hawaii and Genevieve right which has reached Cat 5 (157 mph or stronger) briefly this morning. 

Orion above the Rincons at 4:45 am MST this morning.

Just a few CG flashes detected over eastern Pima County during the 24-hours ending at 0903 UTC (0203 am - above) this morning. Only two sites across entire ALERT Network had rain during the 24-hours ending at 9:00 am this morning (below) - dry here.

Plumes for QPF at airport (above, from 06 UTC runs) indicate slight chances for light showers next several days. The TUS POPs from same runs (below) indicate 40 to 50 percent chances for TUS. The current NWS weekend forecast for the airport is at bottom.

Another Donut Hole Day

Heavy clouds overhead yesterday at 5:00 pm MST.

Plot of detected CG flashes (from Atmo - above for 24-hours ending 0903 UTC) shows a small donut hole over metro area.

Rainfall reports from ALERT Network (above and below for 24-hours ending at 8:00 am this morning) indicate that showers mostly avoided the city. Here at the house we had a huge crash of thunder around 2:30 PM but no rain. There were scattered amounts around of more than half an inch.

The 06 UTC GEFS plumes for QPF at airport (above) indicate little activity until next weekend and beyond. The POPs at TUS (below) reach above 50 percent early next week.

Light Showers Yesterday

View of Catalinas at 6:45 am MST this morning.

Plot of detected CG flashes yesterday (below - from Atmo) shows that storms mostly avoided Pima County yesterday.

However, light rains were widespread across the ALERT Network (above and below). Note that a few sites recorded amounts from a half to over an inch. Here at house we had 0.07" in late afternoon; TUS reported 0.14"; DM had 0.15"; and Atmo measured 0.22".

Current NWS morning forecast for the airport is at bottom.
