PHOENIX -- Tuesday was another dry day in the Valley of the Sun, but that pattern is about to change.

A dry southwesterly flow will start to diminish Wednesday as high pressure moves in from the east and monsoon moisture begins to pump back into the region from the southeast.

The uptick in humidity will help storms develop mainly across eastern Arizona Wednesday, with storm chances returning to the Valley Thursday and into Friday.

Tuesday afternoon, Sky Harbor saw a high of 108 degrees with dew points running a good five degrees higher than Monday, indicating slightly higher humidity levels.

The hottest day of the week in the Valley is expected to be Wednesday.

Communities across the Valley will see afternoon temperatures range from 107 to 112 degrees.

We’re forecasting a high in Phoenix of 109 under mostly sunny skies.

Temperatures will remain a few degrees hotter than normal for this time of year in the Valley on Thursday, before dropping a few degrees below normal Friday and into the weekend.

The seasonal average at Sky Harbor is 105.

A small chance of isolated storms continues for the Valley heading into the weekend.
