The last of the trough, that produced scattered showers and thunderstorms on Saturday, continues to exit the area; as a result, isolated showers and storms cannot entirely be ruled out in Gila and Pinal Counties, as well as far eastern and southeast Arizona on Sunday evening. Any storms that develop could produce gusty winds and heavy downpours.
Once we kick that weak system to the curb, we will make room for incoming high pressure on Monday. A strengthening high pressure will bring abundant sunshine and lower humidity this upcoming work and school week. Of course, this also means no more significant rain and storm chances, at least not for the next week.
In addition to quiet, sun-filled conditions, quite seasonal temperatures will also prevail. Valley highs will hover in the lower 100's, to right at 100 degrees, through most of the work week. Valley locations might even catch a couple of days with highs in the upper 90's, as the humidity looks to increase late-week. This time of year, the Phoenix Metro typically sees high temperatures near 100 degrees and lows in the upper 70's. In the mountains, high temperatures will range from the 70's to near 90 degrees this week.
While the rain forecast is a bit wonky into next weekend, it looks like monsoonal moisture could pump back into the region starting late-week. We will keep the extended forecast dry for now, as storms aren't looking too promising.
