PHOENIX -- Look for a gradual warming trend as we head toward the weekend.

By Saturday, expect Valley highs to be in the upper 80s with overnight lows in the 60s. After that, temps will moderate as we head into next week, but no rain is in the forecast.

From the National Weather Service discussion:

The northerly flow aloft is expected to continue over the region with north to northeast breezes diminishing through the day.

High pressure will build into the area from off the Pacific for the remainder of the week, resulting in clear skies.

Temperatures will generally peak over the weekend before low pressure passes to our north through parts of the Great Basin. That will result in slight cooling next week.

As the high-pressure ridge continues to build into the western states, some cirrus is spilling over the ridge axis, but this looks to be limited to areas of northern Arizona.

A large swath of cloudiness and rain exists across Mexico as well as south-central and southeast states, which is largely associated with remnants of Vance but is also aided by a cold front.

Meanwhile, an upper low continues to sag southward over northwest Mexico. It has managed to pull some cloudiness into far southeast Arizona.
