PHOENIX -- A storm system that dropped the first snow of the season in Flagstaff Sunday morning is also going to make temperatures plunge headed into Monday morning.

An area of low pressure tracking through the region from the Pacific helped produce light rain showers across Northern Arizona Sunday morning, with snow dropping down to 7,000 feet.

While Flagstaff saw little accumulation, some areas around 8,000 feet saw about an inch of powder, according to meteorologists at the National Weather Service of Flagstaff. Operators at the Arizona Snowbowl Ski Resort reported two inches at the base, which is an elevation of 9,200 feet.

Between Friday afternoon and Sunday afternoon, high temperatures in the Phoenix metro dropped more than 20 degrees. Sky Harbor reported an official high of 73 after a morning low of 64 Sunday. On Friday, that high temp was 95, nearly tying an daily temperature record.

As a weaker trough moves through the state, more light snow may fall as low as 6,500 feet by Monday morning.

Light winds, clear skies and low humidity will also allow temperatures dip to the coldest levels of the season. Freeze Warnings are in effect for communities in northeast Arizona below the Rim, as well as parts of Yavapai County, including Prescott from midnight to 8 a.m. Monday.

In the Valley, overnight lows in the Phoenix core will dip into the low 50s, while outlying Valley communities will see their first 40s of the season.

Expect sunny skies around the Valley Monday afternoon with highs in the low 70s. The 70s will stick around through Tuesday. Warming into the 80s is expected for Wednesday. Overnight lows should stay in the 50s.
