Forecast Discussion: A strong convective system moving through the Phoenix area last night resulted in strong winds, heavy rain and frequent lightning. Sky harbor reported gusts up to 61 mph with temperatures cooling off by almost 25°F within an hour! Looking ahead, we've got more activity on the way. Even though today will be a down day for thunderstorm activity, the moisture influx from a tropical system in the Eastern Pacific will return cloudy skies and rain to the region. But, before that, strong thunderstorm outflows are expected to traverse northwestward through Pinal County tomorrow. This could potentially kick up some dust and transport it into Maricopa County. However, the rain following the gust front should suppress it fairly quickly. Thus, expect PM-10 concentrations to slightly increase. In terms of ozone, we should be in the Good range. The incoming cloud cover from the tropical moisture inflow later this week should inhibit some of the tropospheric ozone production. Check back tomorrow for more. Until then, have a good day! -P.Patel
