PHOENIX — After a weekend cool-down, we are tracking another drop in temperatures midweek as a storm system dives into Arizona, bringing breezy to windy conditions along with some rain and snow.

In the Valley, we're still dealing with elevated levels of small particle pollution (dust and smoke). Some of the smoke from the Horton Fire is expected to push into the Valley early Monday. The worst air quality will occur in the morning, gradually improving throughout the day.

A Burn Ban remains in effect tonight across Maricopa County, prohibiting the use of wood-burning fireplaces, stoves, and outdoor firepits.

By Monday morning, the Valley's temperatures will drop into the mid-to-lower 40s, with a mix of clouds to start the day. Throughout the afternoon, temperatures will warm back up into the lower 70s.

Tuesday an area of low pressure will dip down into Arizona bringing snow showers across the Rim, Northern Arizona, and the White Mountains through Wednesday morning.

A couple of inches of snow is expected in the high country. Flagstaff could see 2-4 inches with 6-8 inches possible on top of the San Francisco Peaks. Those snow showers will continue into Southeastern Arizona Wednesday afternoon and evening. The high points in the White Mountains could see 6-10 inches of snow.

Meanwhile, a few light rain showers in the Valley will be possible overnight Tuesday into Wednesday morning. Only a couple hundredths of an inch is expected.

This storm will also bring breezy to windy conditions across the state.

A High Wind Watch is in effect for the Colorado River from Tuesday morning through Wednesday. Wind gusts are expected to reach up to 60 mph. Limit travel plans in Western Arizona during this time, especially in high-profile vehicles.

In the Valley winds gusts will likely kick up to 20 mph and in Flagstaff they could reach 25-35 mph. Again, be careful if you have plans in the High Country.

Behind the storm, temperatures are set to tumble across the state.

Valley highs will remain near normal in the mid-60s through the rest of the week with morning lows in the lower 40s to upper 30s. Some rural Valley communities could face freezing overnight temperatures late this week.

Afternoon temperatures in Flagstaff will struggle to get out of the freezing mark by Wednesday and morning lows will dip into the single digits for the end of the week.
