Synopsis and Discussion

AQI readings are hovering in the upper Code Green range on Wednesday. A backdoor cold front will sweep through tonight, going largely unnoticed with really no clouds to speak of. In its wake, some cooler air will arrive for the next couple of days before surface high pressure drifts southeastward to the coast by Saturday, turning our surface winds out of the south and allowing some warmer air to return. One more day of upper Code Green particle pollution concentrations is anticipated tomorrow before the stagnating air mass associated with the aforementioned high pressure allows readings to creep into the lower Code Yellow range. With the waning October sun providing less solar energy for ozone production, readings will remain in the Code Green range. (Greg Perrotte / perrotgt@forsyth.cc)
