Hard freeze watch in effect for parts of Arizona. Here's a look at where

A hard freeze watch was issued for several areas outside of Tucson from Saturday night to Sunday morning, according to the National Weather Service.

The warning was issued for Cochise County, upper Santa Cruz River Valley/Altar Valley, upper San Pedro River Valley, eastern Cochise County below 5,000 feet and upper Gila River Valley.

Jim Meyer, meteorologist for the weather service in Tucson, said the hard freeze watch would not affect Tucson.

A hard freeze is when temperatures reach below 28 degrees. Meyer said it's unusual to have temperatures that low this time of year. Typically, these areas will see their last freeze of the season, below 31, around this time, not a hard freeze, according to Meyer.

The warning was primarily out of precaution for those in the beginning of growing season.

"Since we are expecting a hard freeze below 28 over there and since their growing season has already started with some things, we went ahead and issued the warning for that, even though they do get hard freezes a lot over there in the wintertime."

The hard freeze watch comes after a cool weather system which Meyer said would come through pretty quickly. While they did not expect a lot of rain to fall, he said the cool air behind it would probably push.

Meanwhile, a wind advisory was in effect until 9 p.m. Friday: Southwest winds 25 to 35 mph with gusts up to 45 mph expected. Areas included upper Santa Cruz River and Altar Valleys, including Nogales; upper San Pedro River Valley including Sierra Vista/Benson; eastern Cochise County below 5,000 feet, including Douglas/Willcox; upper Gila River and Aravaipa Valleys including Clifton/Safford.

There was a 30% chance of rain on Saturday night with high temperatures in the 70s on Friday and Sunday but dipping down to 62 degrees on Saturday.
