Phoenix is waking to clear skies and temperatures in the low 60s Wednesday, but one more warm, quiet day is on tap before the forecast takes a sharp turn. Mostly sunny skies will push the temperature to about 86 degrees, with light southeast winds and no rain expected.
Thursday will look much the same, with a high near 86 and only a slight chance of precipitation. The calm stretch ends late Thursday night, when showers could begin after 11 p.m. and thunderstorms become more likely overnight.
Rain Arrives Before Friday Morning
Friday is expected to be the first notably unsettled day, with showers and thunderstorms likely across the Phoenix area. The high should reach only about 75 degrees, and rainfall totals could run from a quarter-inch to a half-inch, with locally heavier downpours possible.
Those heavier bursts could create minor flooding in washes and at low-water crossings, particularly Friday and again Sunday. There are no active watches or warnings for Phoenix Wednesday morning, but forecasters say flood watches may become necessary as the storm pattern develops.
Checking Local Flood and Rainfall Conditions
Residents can check current rainfall, weather, stream and impoundment information on the Flood Control District of Maricopa County’s MCDOT Flooded Roadway Map, which is updated every 10 minutes. The district cautions that QPF values on its ALERT map are forecast estimates, not observed rainfall. The National Weather Service Phoenix also notes that rain can vary across the metro, so conditions at Phoenix Sky Harbor may not reflect rainfall elsewhere in the area. A separate past event illustrates the potential for flooding in normally dry channels: the National Weather Service Phoenix reports that rain from the evening of November 17 through the evening of November 20, 2025, caused flash flooding and flows in normally dry creeks and washes in central Arizona, including Maricopa County. That event is distinct from this weekend’s forecast.
A Wet And Cooler Weekend Follows
Saturday should offer a brief pause, though skies will remain mostly cloudy and a few showers could develop late in the day. The bigger change arrives Saturday night, when widespread rain is expected and temperatures dip into the mid-60s.
Sunday looks like the wettest and coolest day of the weekend, with showers followed by thunderstorms, a 90% chance of precipitation and a high near 71 degrees. Rainfall could add another half-inch to three-quarters of an inch around Phoenix, with higher totals possible in the foothills and higher terrain northeast of the city.
Sunshine Returns Next Week
Showers may linger into Sunday night, with the area drying by Monday.
