Arizona weather forecast: Another day of record-breaking heat expected
Weekend Weather Forecast: March 20-22
Extreme heat warnings continue in the Valley through 8 p.m. Sunday.
PHOENIX - Happy Spring! Our Friday forecast felt like summer with another record-breaking day as Phoenix hit a high of 105° with the average sitting at 79. This breaks our 2017 record of 96°.
The weekend:
Extreme heat warnings continue in the Valley through Sunday 8 p.m.
Those who are sensitive to the heat should limit time outdoors, and use caution in the heat.
The weekend will also be record-breaking with Saturday sitting at around 105°. This will break our 2004 record of 97°. Sunday will bring in a high of around 101°, also breaking a record that was set back in 1990 of 94°.
The ridge of high pressure responsible for bringing in the extreme and historic heat will push out of the state with another ridge forming for early next week. This will allow for temperatures to remain in the triple digits.
By next weekend we could see temperatures drop into the upper 90s. If you are going to be outdoors for any events happening around town, just be prepared to hydrate. Apply sunscreen. And take plenty of breaks.
Morning Weather Forecast - 3/20/26
Buckle up! Our stretch of triple-digit temperatures will last for some time yet.
