FORECAST: More storm chances on the board this week

The monsoon moisture flow is opening up, and we have chances of showers and storms in the Valley every day this week! By the end of the week, that will also possibly bring our high temperatures below 100°.

PHOENIX — A wall of dust swept through the Valley Sunday evening, dropping visibility to less than a quarter mile and significantly impacting air quality. Some of that lingering dust will stick around overnight and could continue to cause air quality concerns into Monday morning.

As we head into the new week, daily chances of storms remain in the forecast, though some days will be more active than others.

For Monday, there is some disagreement among forecast models. Some show a more active setup with storms developing late in the afternoon and evening, while others keep activity more limited. The dust storm that moved through the Valley may briefly leave a layer of drier air, which could reduce storm coverage locally.

Because of that, storm chances in the Valley on Monday will stay isolated, with highs near normal, topping out around 108 degrees.

Monsoon moisture will remain in place through much of next week as our monsoon ridge stays near and northeast of the Four Corners. This keeps daily storm chances in the forecast and temperatures closer to seasonal averages.

Looking ahead, uncertainty increases late in the week. An inverted area of low pressure may move in from the southeast, which could boost rain chances heading into next weekend and bring temperatures down below normal. Confidence is increasing, but there are still details to be worked out. Stay tuned as the forecast becomes more refined.
