MOST ACCURATE FORECAST: Big cool-down on the way

Posted
and last updated

PHOENIX — A series of systems moving through the region will bring much needed cooler air to the Valley this week to finally drop our afternoon temperatures into the 90s.

Phoenix has now had 112 triple-digit days in a row, as of Sunday. The previous record was 76 consecutive triple-digit days set in August of 1993. That means we have beaten the previous record by over a month!

We will likely have one more day in the triple digits before our temperatures drop into the 90s for a few days.

Scattered showers and thunderstorms could bring brief heavy downpours, localized flooding, gusty winds, blowing dust and lightning are still expected for Monday afternoon and evening. These showers will stay east and north of the Valley.

Drier air moves in midweek as temperatures stay cool and below normal.

As drought worsens across Arizona, there are only a couple of weeks left to get rain in the buckets before the monsoon season officially ends on September 30th.

So far, Phoenix has only picked up 0.74 inches of rain this monsoon season. Our 30-year average (which is considered our "normal" amount of rain) is 2.43 inches. But, it's important to remember, that is a decrease from the previous 30-year average of 2.71 inches (from 1981-2010) as our Valley climate continues to get hotter and drier.
