PHOENIX — It's a hot start to the week in the Valley!
Temperatures are peaking in the low 100s and will stay there through the middle of the week.
Scattered showers and thunderstorms are still possible across northern Arizona (mainly north of I-40) on Tuesday, but our Valley forecast will stay dry.
Air quality continues to be an issue, too. An Ozone High Pollution Advisory is in effect through Tuesday. Limit your time outside in the afternoon hours if you have asthma or COPD, or you may have difficulty breathing.
Breezes will pick up by mid-week as we track another storm system passing to our west. That will prevent ozone pollution from building up throughout the day.
That storm system will also help drop temperatures a few degrees across Arizona.
Valley highs will fall into the upper 90s by Friday and stay there through the holiday weekend.
We're also still tracking a Flood Warning in effect for parts of the Gila River in southwestern Arizona as the flow increases due to water releases from the Painted Rock Dam. This warning has now been extended through May 30th. Do not attempt to cross any flooded roadways.
