Was thunderstorm activity expected in the Valley?

Mark O’Malley of NWS told KTAR News 92.3 FM on Thursday morning that there would be a 30% chance of rain on Thursday night into Friday morning.

“And then slightly better chances on Friday afternoon and evening, with up to a 50% chance of a shower or thunderstorm,” he said.

However, O’Malley said the storm would only hit certain parts of the Valley.
