PHOENIX -- Some Valley residents spent this morning cleaning up after isolated thunderstorms, including a microburst, hit yesterday evening.
The worst of the damage was in East Mesa, where a microburst took the roof off of a mobile home and toppled a 20-foot section of a block wall. The storm also brought about 1.3 inches of rain in about 30 minutes. Most of the rest of the Valley saw no rain, but a nice lightning show lit up the sky around sunset.
Tuesday morning brought muggy conditions with relative humidity near 50 percent, and overnight lows near 90 degrees.
This afternoon, temperatures are forecast to top out near 103 degrees with a chance of more afternoon and evening thunderstorms.
There is an even better chance of more widespread storm activity on Wednesday, with double digit highs likely for Thursday and Friday.
A low-pressure system from the west will add to our instability, and high pressure shifting east will aid in importing more moisture into Arizona from the south.
Storm chances continue through Thursday before we warm up and dry out for the weekend.
