Phoenix logged its second consecutive Category 5 dust storm overnight, according to AZFamily meteorologist Royal Norman, making back-to-back top-rated haboobs a notable event even on the new rating scale developed by Arizona State University. The streak was also confirmed by KTAR and U.S. News.
The Monday night storm was the more severe of the two, producing higher winds and resulting in poorer air quality. The overnight storm was the sixth dust event recorded in the Valley this year. High Pollution Advisories for dust are now in effect across central Arizona, including metro Phoenix.
No strong signal for a significant return to monsoon rainfall exists at this time, Norman reported. Evening storm chances stand at 20% Sunday and 30% Monday night.
First Alert Weather Days for Extreme Heat run through Sunday evening, with highs expected in the 109-112 range. Temperatures are forecast to drop below average early next week.
