PHOENIX -- Sunshine and temperatures in the 70s are reason enough for snowbirds to flock to the Valley of the Sun in December.

These inviting winter conditions are sometimes called "Chamber of Commerce weather" because of the appeal to tourists.

This week, Mother Nature is not disappointing visitors or desert-dwellers.

Thursday afternoon, Sky Harbor Airport reported an official high of 71 degrees, after a morning low of 49 degrees under clear skies. The seasonal norm for this date is a high of 65 degrees.

High pressure continues to have a firm grip on the region. This weather feature will keep temperatures several degrees above normal through next week.

One change we’re tracking is an increase in cloud cover for the weekend.

Forecasting models originally indicated an area of low pressure would sweep across southern California and push clouds in our direction. They’ve abandoned this idea, but are now indicating a wave of moisture from the northwest will push some high clouds in our direction.

The clouds will not bring any rain, but will drop our daytime highs a couple degrees.

Friday, expect a morning low of 44 degrees with an afternoon high of 71 degrees.

On Saturday and Sunday, look for partly cloudy to mostly cloudy skies with highs topping out at 69 degrees.

The sunshine and 70-degree temperatures return Monday.
