PHOENIX -- Colder air is entering Arizona and it looks like we’ll see unseasonably cold temps for Christmas day statewide.

Also, in northern Arizona, we’ll see a few areas that get a dusting of snow.

An upper-level ridge currently overhead will quickly push eastward tonight, with increasing high clouds blanketing much of the region. Overnight lows tonight should be a few degrees warmer in most spots due to the cloud cover.

The next weather system, which is currently entering northern California, will slide southeastward over the next couple days while also deepening into a closed low as it enters northern Arizona.

This cold front will continue to march through our area Thursday evening, reaching eastern Arizona around midnight. Winds will increase behind the front with gusts up to 30 mph possible across southwest Arizona Thursday afternoon.

Given the dry trajectory of this low-pressure system and dry conditions already in place, we’re expecting only marginal moisture levels. As a result, we may see a few snow showers in the mountains, but no rain is expected around metro Phoenix.

The main impact for the Valley from this trough of low pressure is going to be unseasonably cold temps, with highs only in the 50s from Friday to Monday and overnight lows dipping into the 30s.

At this point, because of expected breeziness, we don’t foresee any issues with temps dropping below freezing in metro Phoenix through early next week.
