A Flood Watch is in effect for the Phoenix metro through 5 a.m. Sunday after an outflow boundary pushed blowing dust through the area around 9:15 p.m. Saturday, according to Arizona's Family meteorologist Pete Mangione.
The watch, which began at 5 p.m. Saturday, covers isolated areas, particularly in the eastern higher terrain, where rainfall amounts between 0.50 and 1.0 inches are possible. Rain may miss some parts of the Valley entirely.
First Alert Days are in effect from Saturday evening through Monday. Once the flood watch expires early Sunday, isolated showers and storms remain possible. Storm chances rise from 20% during the day Sunday to 40% Sunday night, a probability that holds through Monday evening.
A significant temperature drop accompanies the active pattern. After hitting 113°F Saturday, highs fall to 106°F Sunday and 100°F Monday, then settle in the 102°F to 104°F range Tuesday and Wednesday before climbing back toward 105°F late next week.
The National Weather Service Phoenix office separately noted storms capable of producing heavy rainfall from late Saturday through early Sunday morning. The MCDOT Flooded Roadway Map provides real-time stream and impoundment data updated every 10 minutes for Maricopa County.
The flood watch expires at 5 a.m. Sunday.
