A northwestern frontal boundary is headed Phoenix's way and bringing with it strong gusty winds. Some showers might be possible but localized and light. Most rain will be virga.
Unfortunately, the desert floor is dry and warm. The 30mph winds will create dust and air quality hazards for those individuals who suffer from respiratory conditions. People with lung issues may want to stay indoors.
Forecast Discussion: ...A PM-10 HIGH POLLUTION ADVISORY HAS BEEN ISSUED FOR WEDNESDAY... The weather system that will bring winds to Arizona has strengthened a little more. Phoenix could see sustained winds between 15 and 25 mph at times with gusts as high as 35 mph. This is more than enough to generated blowing dust locally. In addition, we anticipate dust from dry deserts to the west (Yuma/southern California). We can lean on any precipitation to help minimize impacts as they disturbance will be dry. Erring on the side of caution, we are going with a High Pollution Advisory for Wednesday as it is highly possible that PM10 concentrations could exceed the standard. Wind conditions improve Thursday and dust levels should also settle into the lower Moderate range. Daytime highs are expected to briefly fall into the lower 70 on Thursday, but rapidly warm to the upper 80s by Sunday. Check back tomorrow for more. Until then, have a good day! -J.Paul
