PHOENIX -- A series of weather systems will move through Arizona this week, bringing a break from the early summer heat and maybe some rain, too.
The first system moved through mainly during the overnight hours, bringing a few sprinkles to the Valley and some decent rain to the Rim Country and White Mountains. As that system moves into New Mexico, a few showers are possible throughout the day still in Northern and Eastern Arizona today.
A storm system off the coast of Southern California will slowly move toward Arizona tomorrow, bringing the Valley a 20-percent chance of showers Tuesday afternoon. There's about a 50 percent chance of showers and thunderstorms in the high country.
Both today and tomorrow's storms will usher in cooler air, bringing Valley highs only in the low to mid-80s today through Wednesday under partly sunny skies.
Temperatures are forecast to warm to the upper 80s Thursday and Friday before the 90s return for next weekend.
