More rain and cooler air this week

PHOENIX — A mix of showers and thunderstorms will continue to move across Arizona today, although the heaviest part of the storm is already moving out of the Valley.

This system is also bringing a noticeable cool-down. Highs will drop into the upper 60s and low 70s, and morning lows will settle in the 50s.

It’s first in a series of storms expected to move across the state through next week.

The next storm may arrive on Tuesday with even colder air and another chance for rain and possible snow if snow levels drop. Early morning lows in the Valley could dip into the upper 40s and low 50s by Wednesday morning.

This Tuesday system may also slow down the morning commute, which is why it is an ABC15 Weather Action Day.

A third system is expected late next week and will bring another round of colder air, rain, and snow.
