Arizona weather forecast: Triple-digit heat to persist for Phoenix

PHOENIX - After shattering records around the state and region on Wednesday, we'll do it again today.

Today:

The strong ridge of high pressure atop the Southwest will continue to bump temperatures up all around the region. In fact, high temperatures will not reach their peak in Arizona until Friday into Saturday.

Today we'll see an afternoon high of 104 in Phoenix. In Flagstaff, the high will climb into the low-mid 80s-- which is closer to the July average high. It will remain sunny and dry with generally light winds. Yet again today, record highs will fall across the state. In Phoenix, the current record high is 96 degrees, set in 2017.

Looking Ahead:

The forecast high climbs to 106 on Friday in Phoenix. The high could reach 105 on Saturday, and 102 on Sunday.

The anomalously strong high pressure dome will weaken and slip to the southeast by Sunday. However, it's replaced quickly next week with a new ridge. This will continue to keep the Valley around 100 degrees through next week, with over a week of record temperatures likely.

The forecast currently remains around 100 Monday, 101 Tuesday, and 102 Wednesday. Morning lows will stick in the upper 60s to low 70s, setting records as well.

For now, there's still no relief in sight as sunshine and heat prevail for the next 10 days.
