Temperatures could fall well below freezing in parts of Southern Arizona overnight, with a hard freeze warning for much of Cochise County, and freeze warning in effect around Nogales.

"The coldest night of the young season is on tap tonight," National Weather Service forecasters said. Wednesday's high temperatures are about 10 degrees below normal.

Thermometers could read as low as 24-28 degrees in the Upper San Pedro Valley, eastern Cochise County and Upper Gila River Valley, including the Sierra Vista, Benson and Willcox areas, NWS officials said. A hard freeze warning will be in effect from 2 a.m. and 9 a.m. Thursday for the parts of that area below 5,000 feet.

Temperatures between 29-32 degrees will be possible in the Upper Santa Cruz Valley, near Nogales, and Altar Valley to the west, where a freeze warning will be in effect 2 a.m. to 9 a.m. Colder spots may occur in washes and other low-lying areas.

Wrap your pipes, cover your plants, bring your pets inside and be kind to people who are outdoors at night. NWS is forecasting temperatures may drop as low as 24 degrees in some parts of Southeastern Arizona, and even lower in washes and low-lying areas.

There should be a bump in high temperatures on Halloween, with continued warming through this weekend as temperatures level off a few degrees above normal, officials said.

Overnight lows will remain chilly through Friday, then gradually warm into next week.
