Freezing temps, mountain snow expected in Tucson area

Tucsonans might want to bundle up and cover their plants this weekend.

A new forecast shows potential freezing overnight temperatures and showers this weekend, the National Weather Service in Tucson says in its latest outlook for southern Arizona’s weekend.

A storm system is expected to roll through the region and bring “chances for showers and mountain snow showers” through Friday night.

The Tucson metro area should expect some scattered showers Friday, up to a quarter inch of rain through Saturday morning. There’s also an outside chance for “near freezing” temperatures in outlying metro areas Sunday and Monday, the weather service says.
