Arizona weather forecast: Higher storm chances later this week

PHOENIX – While our 110 degree streak came to an end this weekend, our temperatures jump right back up today.

The backstory:

Over the weekend, Sunday hit 108 degrees for an afternoon high. This ended our 14-day streak of 110+ degree high temperatures that stretched between July 27 and August 9. The hottest day of the streak was 118 degrees. The longest streak on record was 31 days, set back in 2023. The stretch this year was the 4th longest on record at Sky Harbor Airport.

Today:

The forecast high temperature today is 110 degrees. The National Weather Service has put out an Extreme Heat Warning for the Valley, much of Maricopa County, and part of Pinal County through 8 p.m. Tuesday.

It will be dry and mostly sunny in the Valley. Around far southeastern Arizona, a few scattered showers/tstorms will be possible.

Tomorrow:

Again tomorrow, the high temperature climbs to 111 in Phoenix. It will be dry and mostly sunny. Around the higher elevations of Northern Arizona and along southeastern Arizona, additional spotty showers and storms will be possible.

Regardless of storm chances, it will be muggy across the state through the week.

Later This Week:

By Wednesday, particularly in the evening, storm chances will begin to increase as high pressure shifts northeastward and sets up near the Four Corners area. This will allow for better monsoonal moisture to setup around the state.

Rain chances increase to 10% Wednesday evening, 20% Thursday, and 30% Thursday evening. Chances continue into Friday and early Saturday. The best chances for the Valley are Thursday and Friday late day-evening.

As rain chances increase, temperatures will fall. The forecast high temperature slips to around 107 on Thursday and 104 Friday and Saturday.
