Arizona weather forecast: Phoenix hits triple digits before widespread rain arrives in Arizona

Warm temps before we see some rain in Phoenix

We're going to feel the heat before things finally cool down and rain arrives. FOX 10's Erica Horvatin has the details on that timeline.

PHOENIX - Tuesday was another warmer-than-normal day across Arizona.

Phoenix hit a high of 98 degrees with mostly sunny skies. A few showers and thunderstorms passed through the Kaibab Plateau and Page, Arizona. Showers will be isolated throughout the evening, and the night will be mainly dry.

Looking Ahead:

Wednesday will be a warmer, dry day for most of the state.

In Phoenix, lows will fall to around 78 degrees, before warming to a high of around 101. A disturbance will track through the Four Corners, bringing isolated showers and thunderstorms to far eastern Arizona.

Rain will be possible late morning through the evening in Navajo and Apache counties, down to the White Mountains, and even a pop-up or two along the Mogollon Rim.

Thursday will be drier out east, with only a few showers in the White Mountains.

Temperatures to Drop:

The warm temperatures will last through the second half of the work week, eventually dropping over the weekend as a storm system and tropical moisture impact the state.

Friday will be mainly dry and warm, with a breeze in Phoenix.

Rain Chances Increase:

On Saturday, clouds and rain chances will increase in Arizona, and widespread rain is likely Sunday through Tuesday.

The exact timing and heaviest rain locations are still to be determined on the setup of the system. Temperatures will fall into the 90s and even 80s as the system tracks through the Southwest Saturday through Wednesday.

Hurricane Rachel weakens while moving west, but its remaining moisture could head to Arizona.
