FORECAST: Any relief from the 100s?

It's been a hot start to the week! Phoenix ended up just one degree shy of the daily heat records on Monday and Tuesday as high pressure sat overhead. That ridge of high pressure is now slowly moving east as low pressure approaches from the southwest, so temperatures will start to drop and winds will pick up across Arizona.

MOST ACCURATE FORECAST: Hot and breezy Wednesday, high fire danger

PHOENIX — It's been a hot week so far in the Valley!

High pressure is now slowly moving east as low pressure approaches from the southwest, so temperatures are gradually dropping.

Phoenix will top out near 100 degrees for the rest of the week with overnight lows in the low 70s.

A storm system passing to our north could knock us out of the triple digits this weekend, picking up the winds and elevating fire danger.

Expect Valley highs down near the seasonal average of 95 degrees by Sunday.

We're also tracking an Ozone High Pollution Watch on Friday. So plan on limiting your time outside if you have any respiratory issues like asthma, bronchitis or COPD.

Exposure to ozone can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease, and reduce the body's ability to fight infection. Symptoms may include itchy eyes, nose, and throat, wheezing, coughing, shortness of breath, chest pain, and upper respiratory issues.

Please help reduce ozone pollution by driving as little as possible, carpooling or using public transit. Even waiting to refuel your vehicle until after dark and avoiding idling in long drive-thru lines helps too.
