Today's Forecast: Jul 13, 2014
Forecast Details: Issued Friday, July 11 at 2:16 PM: Sunday's Air Quality Forecast for Ozone is MODERATE for the Southwest Coast and Mid-Coast regions and GOOD for the remainder of the state while Particle Pollution is MODERATE statewide. [Sat 1:49 PM -- Air Quality models are backing off a bit on how much ozone will be brought to Maine. I'm holding on to this forecast because it is possible and with a front approaching pollution levels can get concentrated ahead of it. Surface winds will be somewhat favorable and transport level conditions are favorable. Particle pollution levels have been building in areas ahead of the front so Moderate levels are possible for some areas of the state.] -- Forecaster: Webster
Tomorrow's Forecast: Jul 14, 2014
Forecast Details: Issued Friday, July 11 at 2:16 PM: Monday's Air Quality Forecast for Ozone is GOOD statewide while Particle Pollution is MODERATE statewide. [Skies are forecast to be overcast which should keep ozone levels down but other conditions are right for ozone so any sunshine will quickly create ozone.] THIS FORECAST WILL BE UPDATED BY 3 PM SUNDAY. -- Forecaster: Webster
