PHOENIX — Big weather changes are on the way for Arizona as the remnants of Tropical Storm Priscilla combine with an approaching Pacific storm system, resulting in several days of rain.
Our best chances for widespread, heavy rainfall arrive Thursday through the weekend, with Friday and Saturday looking the most active.
Along with the rain, a few isolated thunderstorms are possible. These could bring strong winds, lightning, small hail, and quick-hitting downpours.
Rain totals will vary quite a bit across the state.
Some spots may only see a quarter to half an inch, while others could pick up one to two inches, and a few localized areas may see closer to three inches.
Due to the widespread impacts, Thursday, Friday, and Saturday will be ABC15 Weather Action Days.
Now is the time to make sure you and your family are prepared.
A Flood Watch is in effect from Thursday morning through Saturday evening for western, northern, and central Arizona.
Flash flooding will be a big concern statewide, so expect normally dry washes and creeks to flow and watch for water collecting in low-lying areas.
On the brighter side, this wetter pattern will also bring a break from the heat!
Highs will dip into the 80s by the weekend, which is roughly five degrees below normal for this time of year.
Stay with ABC15 as we track these big changes and keep you ahead of the storm.
