Phoenix, Arizona — The coldest mornings of the season so far are settling across central and northern Arizona, with widespread freezing temperatures expected early Friday and again Saturday morning. Freeze Warnings have been issued for multiple valleys and desert locations, raising concerns for sensitive plants, exposed pipes, and vulnerable populations.
According to the National Weather Service, temperatures are expected to dip to near or below freezing during the pre-dawn hours both days, particularly in areas under active Freeze Warnings. Portions of the lower deserts, including parts of the Phoenix metro area, may see lows in the low to mid-30s, while colder outlying communities and higher elevations could fall into the 20s.
Meteorologists say the cold will be most noticeable just before sunrise, when winds are light and skies remain mostly clear. These conditions allow heat to escape rapidly overnight, leading to sharp temperature drops across valleys and open desert locations.
Several communities across central Arizona are expected to experience their coldest conditions of the winter season so far. Areas such as Phoenix, Glendale, Mesa, Chandler, Casa Grande, and regions extending toward Globe and Prescott Valley could see temperatures cold enough to cause frost or freezing impacts. In rural and higher-elevation locations, the cold may be more prolonged and more intense.
Freeze conditions can have multiple impacts beyond uncomfortable mornings. Unprotected outdoor plants may suffer damage or die, exposed pipes can freeze and burst, and pets left outdoors may be at risk. Individuals without adequate heating or shelter are also more vulnerable during overnight cold snaps, especially during the early morning hours.
Officials are reminding residents to follow the “four P’s” during freeze conditions: protect people, pets, plants, and pipes. Bringing pets indoors overnight, covering sensitive vegetation, and insulating or dripping outdoor plumbing can help reduce damage. Checking on elderly neighbors or those without reliable heating is also encouraged.
While daytime temperatures will rebound into more typical winter ranges later in the day, forecasters caution that cold air will linger through the weekend. Temperatures are expected to gradually moderate by late weekend or early next week, but additional chilly mornings remain possible if clear skies and calm winds persist.
Residents are advised to stay updated on local forecasts and any additional advisories or warnings that may be issued. Weather conditions can change quickly, and Freeze Warnings may be expanded or extended if the cold pattern continues across the region.
