MOST ACCURATE FORECAST: Air quality issues continue with Christmas cool-down on the way!

Posted
and last updated

PHOENIX — Temperatures are staying above average for now, with air quality alerts in effect through Christmas Day in the Valley.

The Maricopa County Air Quality Department has issued a "No Burn Day" for tonight and Christmas Eve, meaning burning wood in fireplaces, stoves, and outdoor fire pits is prohibited.

The Arizona Department of Environmental Quality has also issued a High Pollution Advisory for Tuesday and Wednesday due to stagnant air, which is leading to increased particle pollution.

Air quality will be at its worst during the early morning and late-night hours, so if you have a respiratory condition like asthma, bronchitis, or COPD, try to limit your time outdoors during those periods.

We’ll start to see some noticeable changes in the weather by midweek.

A storm system passing north of us will bring cooler conditions through Arizona, dropping temperatures closer to normal.

Morning lows will still feel chilly, dipping into the mid-40s to low-50s across the Valley. Even so, those temperatures remain a few degrees above average for this time of year.

However, afternoon highs will slide into the mid-to-upper 60s by Christmas Day and stay there for the latter half of the week.

This storm system is also bringing some festive weather to the high country, with light snow chances and even a few flurries possible on Christmas morning.

Areas like the Grand Canyon, Flagstaff, and parts of the Four Corners could see a light dusting.

It’ll also get breezy up north, with gusts reaching up to 25 mph in some spots. So, if you’re heading to higher elevations, brace yourself!

As of December 22, Phoenix’s average temperature for the month is sitting at 63.1 degrees. That beats the all-time record for December, which was 61.3 degrees set back in 1980. With above-average temps sticking around a little longer, there’s a good chance we’ll break that record!
