TUCSON- The Excessive Heat will roll right into Friday but changes will start after that in Southern Arizona. Moisture will start to move in in the upper levels of the atmosphere on Friday with those big puffy clouds.
Chief Meteorologist Rob Guarino says the moisture will start to move into the mid and lower levels and that should increase the chances of storms over the weekend. It's hit or miss for Saturday with a better chance of storms on Sunday and even Monday.
The early call for 4th of July is Dry and Warm with highs near 100 degrees.
