PHOENIX — A storm system is moving through Arizona picking up winds and bringing a big dose of cool air.
Temperatures are dropping by 10 to 15 degrees across Arizona.
We've also seen a few showers and thunderstorms across northern Arizona, including light snow showers over the White Mountains from this storm.
We'll dry out across Arizona overnight and temperatures will rebound as we head toward the weekend.
As winds stay light in the Valley over the next few days, ozone pollution will build up in the afternoon hours.
The Valley is under an Ozone High Pollution Advisory on Thursday and High Pollution Watches on Friday and Saturday. Limit your time outside if you have asthma or COPD, or you may have difficulty breathing.
Temperatures will warm back up to near 90 degrees in Phoenix on Thursday, then we'll hit the mid-90s on Friday and top out around 100 degrees on Saturday and Sunday.
Mother's Day could be a stormy one in parts of our state too as another storm system approaches.
The best chance for showers and thunderstorms will be across northern and eastern Arizona, but there's also a slight chance of isolated showers and thunderstorms in the Valley on Sunday, Monday, Tuesday and Wednesday. Stay tuned for updates as we get closer.
A Flood Warning remains 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 16th. Do not attempt to cross any flooded roadways.
