Forecast Discussion: High pressure continues to build across the area this Monday afternoon. Heat and humidity will also be evident as we move on towards the middle of this week, with ozone levels increasing as a result. Mid to high moderate levels of ozone are possible Tuesday into Wednesday with a good deal of sunshine, heat, and limited chances for any afternoon or evening convection. A cold front moving through early Thursday should result in ozone levels decreasing, and by week's end, we should see mainly good air quality as a cleaner air mass moves in.---McAuliffe
