Forecast Discussion: After a slight chance for showers later Monday afternoon, the weather pattern shifts once again. The monsoon high pressure system slips south of Arizona on Tuesday. Though only a 240-mile movement to the west, this move is enough to alter the pattern significantly. Instead of moist upper-level air pumping in from the south, Arizona will see somewhat drier air from the west. This means a break in thunderstorm activity until Saturday. PM10 levels should return to the Good range following the dust events on Friday and Saturday. Ozone levels could reach the middle Moderate range in the east part of the Phoenix forecast area (Fountain Hills, Queen Valley, Apache Junction, etc.), especially on Tuesday and Wednesday when the flow turns out of the west. Check back tomorrow for the latest. Until then, have a good day! -J.Paul
