AIR QUALITY ACTION DAY
*** Friday’s forecast: Another air quality action day is in effect for the day Friday as ozone production will again ramp up into the code ORANGE range. PM2.5 concentrations will remain moderate under a partly sunny sky with most, if all convection to hold off until the evening hours.
*** Extended forecast: Better air quality is on the way Saturday with more clouds than sunshine, and showers and a thunderstorm around. Both fine particulate and ozone will improve to the upper good range as winds shift into the northeast. Partly sunny skies Sunday into Monday with a continued chance for mostly afternoon and evening thunderstorms. Air quality will continue to be in the upper good to lower moderate range. A strong cold front will finally push through towards the middle of next week to cool us off just in time for the arrival of September.---McAuliffe
