PHOENIX — After a rather sunny weekend, temperatures could drop to below freezing across most of Arizona early in the week following a storm expected to hit on Sunday evening.
Rain chances increase to 90% at night, with precipitation amounts between .1 and .25 inches possible, according to the National Weather Service in Phoenix.
A 40% chance of showers will continue through Monday morning mainly before 9 a.m. prior to picking back up to 30% before 11 p.m.
Most precipitation is expected to fall early Monday morning, with rainfall associated with the cold front primarily between between 4-8 a.m., according to NWS.
Winds from Sunday’s storm system will bring in cold air, which could produce freezing temperatures in the mornings.
A Winter Storm Watch is in effect for areas above 5,000 feet for heavy snow, which includes Gila County and east of Maricopa County.
Areas including Tacna, Blythe and Quartzsite have the highest freeze risk chances, NWS said.
Following the storm, cold air will settle into the region. Freezing temperatures across the lower deserts will be possible in La Paz county Tue AM, then more widespread Wed and Thu mornings. pic.twitter.com/nIorYiGJpO

Just north of Interstate 17, chances for snow begin at Cordes Lakes and could reach anywhere under an inch. Stoneman Lake could see between 4-6 inches of snowfall, while Munds Park could reach anywhere between 8 inches and one foot.
Flagstaff and Kachina Village could get between 6-8 inches of snowfall.
Then, cooler than normal temperatures are expected to last through most of the week.
Lows in Maricopa County dip from 48 degrees Sunday night to 40 degrees Monday night, before dropping to 37 degrees Tuesday and Wednesday night.
Sunday’s high was 68 degrees, but highs throughout the week will remain around 55 degrees.
Drivers are advised to keep a supply kit in their vehicles in case of an emergency, which could include a first-aid kit, high-calorie non-perishable food, a phone charger and blankets.
