PHOENIX -- A strong ridge of high pressure will force temperatures in the Valley to soar next week.

Saturday afternoon, Phoenix Sky Harbor Airport reported an afternoon high of 78 degrees after a morning low of 58 degrees.

A disturbance tracking across northern Arizona was behind the unseasonably cool temperatures across the state.

The Mogollon Rim and White Mountains also saw rain showers and light snow Saturday afternoon from this system. The activity was expected to taper off late Saturday night as the system tracked east out of Arizona.

High pressure building in from the west Sunday will warm afternoon highs back into the mid 80s across the Valley Sunday afternoon. Phoenix should see a high of 84 degrees. Sunshine will be abundant statewide.

The warming trend will continue into Monday, with an afternoon high of 88 degrees in Phoenix.

We’re expecting to see our first 90-degree day of the year on Tuesday. Phoenix will hit a high of 94 degrees.

Temperatures will peak Wednesday, with Phoenix seeing a high of 97 degrees. The 90s will give it a go for one more day Thursday. No rain is expected during this period.

The normal high for Phoenix during this time of the year is between 82 and 83 degrees.
