PHOENIX -- This morning was the coldest morning of the season so far in the Valley, and temperatures are about to get even colder.
Valley neighborhoods dropped to temperatures ranging from 34 degrees to 40 degrees around town this morning. Tomorrow morning, we'll likely see the mercury drop to a range of temperatures between 28 and 36 degrees.
The National Weather Service has issued a Freeze Warning for the deserts of south central Arizona, including the Phoenix metro area, from 10 p.m. until 10 a.m. tomorrow. Under clear skies, Valley temperatures will drop quickly tonight after an afternoon high of just 56 degrees today. Highs will stay in the mid 50s through the weekend, and another storm will bring another blast of arctic air into the state.
There's a slight chance of rain Saturday, with a 40 percent chance of showers Saturday night. A slight chance of rain is in the forecast for the Valley Sunday morning before skies clear and temperatures drop again.
Sunday's highs will struggle to top out in the low 50s and lows will drop Sunday night to the upper 20s and low 30s by Monday morning. Snow is likely in the high country this weekend, especially Saturday and Saturday night.
Tonight, Valley residents are urged to take precautions ahead of the Freeze Warning. Bring your pets inside for the night and cover sensitive vegetation. Temperatures this cold can destroy plants and trees and can be dangerous to livestock and pets.
