North Phoenix Dampened by Isolated Pre-Dawn Thunderstorm
A predawn thunderstorm dumped measurable rain Sunday along the I-17 corridor in far North Phoenix, from Sonoran Foothills to Anthem, while leaving almost the entire rest of the Valley dry.
Amid a few cracks of thunder, brief showers dropped o.04 inches of rain in three gauges near Anthem, and 0.08 inches in Sonoran Foothills and Desert Hills. No rain was recorded in the Norterra area. This map from the Flood Control District of Maricopa County shows the isolated nature of the storm:
The results, meager as they were, were a sort of flip-flop compared to the storm last weekend, when Sky Harbor Airport got 2.19 inches of rain, while NoPho, the I-17 corridor from Norterra to New River, received less than 1 inch (story).
At the beginning of the month, remnants from Hurricane Rosa also dropped wildly different amounts in different locations. That storm deposited 1.65 inches in Norterra, 2 inches in Tramonto and 3 inches on the far west side of Anthem.
The North Phoenix Forecast calls for a slight chance of thunderstorms into Tuesday, with sunny skies and highs in the low 80s by Wednesday.
