PHOENIX -- An abundance of moisture is headed back into Arizona and that is increasing the number of thunderstorms around the state. However, in addition to that, an upper level weather disturbance will be moving toward the state Tuesday and pass overhead Wednesday and that’s going to bring an increased chance for convection, not only in the mountains, but in the deserts of Arizona as well.
Chances for rain in metro Phoenix could be as high as 50% on Wednesday if this scenario plays out, we could see a decent amount of rain.
In the meantime, the increased moisture levels will keep temperatures down. Highs for the next several days are going to be right about the 100-degree mark, give or take a degree or two, depending on your locations around the Valley.
Rainfall estimates are always difficult for monsoon storms, but most of the computer models are telling us that through Wednesday night, we could see around ½” of rain in some Valley locations. Or course, that means some folks will get more and some will get less.
After Wednesday, the atmosphere dries out and the number of thunderstorms statewide will dwindle toward the weekend.
