PHOENIX — Another stretch of dry weather came to an end in Arizona Tuesday. 

Some strong low-pressure systems moved in, bringing rain chances up and the temperatures down throughout the state.

The first system arrived on Tuesday afternoon and brought widespread rain. As much as 2 inches of rain is expected in the Valley through Thursday. Up in Yavapai and Gila counties, 3 to 4 inches of rain is expected.

There will be a slight break in the rain early Wednesday morning before the second system moves in.

FORECAST: 5+ million Arizonans at risk for flash flooding

The second storm system will bring much colder air, and that's when we’ll see a change from rain to snow in the higher elevations. 

The National Weather Service in Flagstaff says the rain will change to a wintry mix down to 6,500 feet, and snow will accumulate above 7,000 feet.

The snow will fall across the eastern Mogollon Rim and White Mountains late Wednesday night and Thursday, impacting travel along the Interstate 40 and Interstate 17 corridors.

With all this precipitation, drivers need to get ready! NWS said the oils, dirt and dust collected on roads will make for slick conditions, especially in the East Valley. You’ll need to give yourself more distance to come to a complete stop.  

The showers taper off late Thursday, and rain chances will die down into Friday. Some showers may linger in the eastern part of the state.
