A system with the potential to spawn thunderstorms and nearly half an inch of rain could be in the Valley by tonight, according to the National Weather Service’s office in Phoenix.
Forecasters call for a 70 percent chance of rain today, followed by an 80 percent chance Wednesday, said Austin Jamison, a meteorologist at the National Weather Service.
"There’s potential for some localized nuisance flooding in the Tuesday night through Wednesday time frame," he said. "It will depend a lot on if we get thunderstorms. We do have that potential. If we do get those, then that will enhance our chances for getting the heavier rain."
Experts are only calling for a 10 percent chance of showers on Thursday with better weather likely returning Thursday night.
Wednesday’s high temperature is expected to reach 64 with a low of 44.
