PHOENIX (AP) -- Metropolitan Phoenix is approaching the halfway point in a four-day cold snap that's expected to mark the coolest stretch of weather the area has seen since 1988.
The National Weather Service said temperatures on Saturday night dipped to 30 degrees at Phoenix Sky Harbor International Airport, 27 degrees in Scottsdale and 25 degrees at the Deer Valley Airport in north Phoenix. No snow was reported.
Low temperatures across the state on Saturday night included 23 at Tucson International Airport and 7 below at the Flagstaff Pulliam Airport.
Authorities are telling residents to keep their pets inside and cover any sensitive plants or outdoor plumbing.
Northeastern Arizona may see snow flurries on Sunday night, though there has so far been little precipitation to fuel a snow storm.
The low temperatures are expected to remain much the same on Monday and Tuesday at Sky Harbor.
The chilly weather is due to a blast of cold air blown in from Canada.
Temperatures are expected to start warming in metro Phoenix on Wednesday, when the low at Sky Harbor is expected to be 35.
The last time metro Phoenix saw such a stretch of low temperatures over several days was in 1988, when the area had four days straight in which the temperatures were 32 degrees or below.
Debbie Babiarz, who owns Greenfield Citrus Nursery, a 34-acre citrus tree farm in east Mesa that Babiarz runs with her husband, said her examination of their property didn't show much damage from Saturday's chilly temperatures. "So far, so good," Babiarz said.
