PHOENIX — An area of low pressure is slowly moving through State 48 and will impact us through Wednesday. These impacts include scattered showers and thunderstorms and cooler temperatures.
Monday starts off with a few showers, but things should quiet down in the afternoon. It’s going to feel cooler too, with Valley highs only in the low to mid-70s—jacket weather for sure.
Valley Rain chances pick back up Monday night, then taper off into Tuesday.
Rainfall totals in the Valley for Monday could reach another 0.25-0.50 inches.
This rain chance will continue overnight Monday into Tuesday morning, then the Valley will begin to dry out.
Meanwhile, scattered showers and storms will continue across the high country and western Arizona through Wednesday. Snow levels could dip to around 7,000 feet Monday morning, so some higher elevations in Flagstaff and the White Mountains might see a little snow, but nothing major.
By the end of the week, big changes again—high pressure builds back in, and we’re looking at triple-digit heat returning to the Valley by Friday.
