Chance of Dust and Gusts This Evening, Cooler This Week with Rain Possible

You might think severe weather is rare in August, but you are wrong when looking at Phoenix right now.

A wall of dust was also seen just south of I-8 in southern Maricopa County which could make its way to the Valley tonight. This situation has been developing rapidly over the last few hours without much warning given earlier today.

The Immediate Threat

Showers and thunderstorms are expected to develop south and east of Phoenix specifically during this evening hour.

If you drive out there, you could see areas of blowing dust entering parts of the Valley tonight due to outflow winds. You might think this is new, but high wind events in Arizona happen more often than people realize without proper preparation.

The Heat Context

High temperatures have reached 111 degrees so far this afternoon which was dangerously close to record territory for the region.

The Extreme Heat Warning expired at 8 p.m. this evening after a long period of intense heating across the valley floor.

Showers and thunderstorms developing south and east of Phoenix could send outflow winds and areas of blowing dust into parts of the Valley tonight as we have discussed before regarding heat events in summer months.

The Cooling Trend

It will be a bit cooler Monday with highs around 108 degrees after the storm system settles down temporarily.

A 30% chance of scattered showers and thunderstorms is expected Monday night into early Tuesday morning to keep things unsettled for those who need restful sleep later in the week.

Flood Risks

Tuesday will be cooler still with an afternoon high around 104 degrees despite any lingering moisture from earlier activity today.

A Flood Watch is in effect from Monday afternoon through Monday evening for southern Arizona including Tucson where water levels may rise quickly after heavy rain.

The Forecast Continues

There will be a 20% chance of showers and thunderstorms Tuesday night into Wednesday morning if you live further south than the Phoenix metro area specifically in Maricopa County or nearby counties.

A line of storms has developed prompting a severe thunderstorm warning for areas including Phoenix Glendale and Peoria according to Pete Mangione who reported this story on Aug. 9, 2026 at 8:05 PM GMT+5:30 which was updated only minutes ago.

The End of Week

Tuesday night into Wednesday morning will bring another chance for rain with a slight probability that could disrupt local traffic patterns significantly if you plan to commute during rush hour.

The cooling trend continues Wednesday with a high of only 101 degrees which is the lowest temperature expected this entire week so far today in Phoenix area including Glendale and Peoria locations specifically mentioned by First Alert Weather App analysts covering the region for PHOENIX (AZFamily).

Thursday may reach just 100 degrees with a slight chance of an afternoon or evening shower or storm developing again later this weekend as seasonal patterns shift.

The end of the workweek looks fairly pleasant by Phoenix standards but keep your eyes open for sudden shifts in wind direction which can happen without much notice during these heat events affecting southern Arizona including Tucson and surrounding high country regions where isolated showers will continue this evening before spreading out Monday through Thursday across northern and eastern parts of the state.

Temperatures will warm back up next weekend with highs ranging from 106 to 108 degrees which might feel like a relief after such a hot spell recently experienced in July or August over the last few years here locally known as Phoenix (AZFamily).
