Cover your plants and bring your pets inside.
A freeze warning in the Valley is in effect beginning at 2 a.m. Tuesday and lasting through 9 a.m. because of a low-pressure cold front that moved in from Utah and Nevada and has settled in the desert, according to Valeire Meyers, meteorologist for the National Weather Service.
The cold front has caused temperatures to drop to the high 30s and even the high 20s in some outlying areas of the south East Valley with an overnight low of 36 degrees in urban areas, Meyers said.
“If you have any decorative plants, cover them up,” Meyers said. “Bring your pets inside, or at least make sure they are sheltered. It’s possible that some areas could drop below freezing.”
Although some areas of the Valley near Phoenix Sky Harbor International Airport received about 1/100 of an inch of rain over the weekend due to increased cloudiness and the cold front, it is expected to warm back up by the middle of the week.
High temperatures in the low 60s in the early part of the week are expected to reach into the 70s with a high of 72 degrees on Wednesday, Meyers said.
“A high-pressure system is building back up and it should stay in the 70s through the weekend,” Meyers said. “That should keep it warm, and we’ll see what happens after that.”
