PHOENIX  -- A Flash Flood Watch has been issued by the National Weather Service for the Valley, beginning at 2 a.m. on Tuesday and running through 2 p.m. on Tuesday afternoon.

As a storm system moves into our state, the chances for rain will soar during the early morning hours on Tuesday. Rainfall amounts around the Valley could be in the 1-2” range and we could see another round of flooding in some areas of central Arizona.

Once again, the mountains to the north of metro Phoenix could receive most of the rain. Our latest forecast maps are also showing a lot of rain is possible along the Mogollon Rim.

There is a chance to see some thunderstorms around the Valley on Monday night as a precursor to the bigger storm, but that chance is only at 20 percent before midnight. After that, the chance for rain for Tuesday is in the 50-60 percent range for metro Phoenix.

There will be a slight chance for lingering storms on Wednesday. But after the storm moves out, we’re going to dry things out and heat up for the rest of the week.  By next weekend, look for temperatures above average for this time of year.
