Wednesday's high temperature in Phoenix was not as hot as the past several days due to the cloud cover overhead. The high only hit 100 degrees with lows in the mid-80s.

Very light showers were the focus through the afternoon.

The area of high pressure to our east will keep moisture in place for the rest of the week. That means our shower and thunderstorm chances each afternoon stays around 20 - 30 percent. The better chances are along the Mogollon Rim and in the higher elevations east of the Valley, but we could see a few storms make it into the Valley as well.

Weather models continue to indicate that we could see a tropical disturbance track north through Baja California and into our state by the weekend. This is still several days away but if this pans out, we could see better chances for more widespread, heavy rainfall Saturday through Monday. Flooding will be something we are watching closely.

As we start to see this surge in moisture, and with the area of high pressure now over our state shifting east, we'll see temperatures fall closer to normal by Friday.

We'll get even cooler by the weekend thanks to increasing cloud cover and storm chances. Highs will top out in the low 100s Saturday and possibly drop below 100 on Sunday with low 100s again early next week.
