Between noon yesterday and midnight, 38,194 cloud-to-cloud lightning flashes were observed across the Valley, with nearly 6,000 cloud-to-ground strikes, according to the National Weather Service. Many parts of the Valley saw heavy downpours. Lake Pleasant received 0.94 inches, and 1.42 inches fell in Sun City Grand (though just 0.31 inches fell in Sun City West, about 3 miles away). Flash floods forced evacuations near Mayer, north of the Valley.
But rain skirted North Phoenix, dropping mere traces from the Norterra area to Anthem. And so it goes with monsoon storms.
Earlier this week, the big storm that rattled NoPho and knocked out power for some residents dumped a good amount of rain across much the region, but still left southern NoPho comparatively dry. Totals from that storm:
- Anthem West: 0.67 inches
- New River North: 1.65 inches
- Desert Hills: 0.63 inches
- Lake Pleasant South: 1.05 inches
- Tramonto: 0.83 inches
- Sonoran Foothills: 0.51 inches
- Norterra: 0.16 inches
- Deer Valley Airport: 0.16 inches
Deer Valley Airport typically sees just a trace of rain in June, and about 1.25 inches of rain in July and 1.28 inches in August. Communities farther north and closer to the mountains—namely Anthem and New River—can expect more in a normal summer.
So far this year since June 1, all gauges between Anthem and Norterra, along the I-17 corridor, have measured less than an inch. Deer Valley Airport has received 2.13 inches in that time period.
And now, back to the heat. The National Weather Service forecast this weekend calls for clear skies, with the next slight chance of storms Monday.
