First Alert Days are in effect across the Phoenix Valley from Saturday evening through Monday as active weather brings storm chances, blowing dust and a sharp drop in temperatures.
Storm chances and Flood Watch
An outflow boundary pushed blowing dust through the Phoenix metro area around 9:15 p.m. Saturday. A Flood Watch began at 5 p.m. Saturday and remains in effect until 5 a.m. Sunday.
Rain may miss some parts of the Valley, but isolated areas—particularly in the higher terrain east of Phoenix—could receive between 0.50″ and 1.0″ of rainfall.
After the Flood Watch expires early Sunday morning, isolated showers and thunderstorms will remain possible. Late Sunday morning is expected to be dry for most of the Valley, but storm chances will increase from 20% during the day to 40% Sunday night.
The 40% chance of rain and thunderstorms will continue through Monday evening.
Phoenix temperatures drop sharply
Relief from the extreme heat is also on the way. After reaching 113°F Saturday, high temperatures are expected to fall to 106°F on Sunday and 100°F on Monday.
Highs will remain between 102°F and 104°F on Tuesday and Wednesday before warming to around 105°F late next week.
