PHOENIX — The wind has died down and skies have cleared out, but we're expecting the coldest night of the season for many in Arizona.

Overnight lows will plummet into the upper 30s to low 40s Thursday morning. A Freeze Warning takes effect tonight for the San Carlos Apache Reservation in Gila County.

Remember to take care of the 4 P's: Pets, Pipes, Plants, People.

Then, temps should slowly rebound the rest of the week. Valley highs will be back in the mid-60s by Friday and upper 60s by this weekend.

Next week looks to start on the warmer side with highs in the 70s, including the first day of winter this Tuesday.

Then, another storm system may bring more rain, snow, and cooler temps to the state. Stay tuned to ABC15 for further updates as we get closer!
