Special status notes:
IMPORTANT WINTER WEATHER NOTES: 1) Particle pollution forecasts are for the smaller particles. Particle pollution levels tend to climb on cold, calm, clear nights due to nighttime inversions which act like a cap trapping pollution close to the surface. In river valleys and areas with more emissions, especially from wood smoke, levels can reach the moderate range. 2) Coarse particle pollution is also a concern during the winter months. Sand and salt mixtures dry out after a storm. Winds and traffic can stir up coarse particle pollution on roadways and parking lots.
Today's Forecast: Jan 30, 2015
Forecast Details: Updated Thursday January 29 at 1:52 PM: Friday's Air Quality forecast for Ozone is GOOD for the entire state while Particle Pollution is MODERATE for all areas except Downeast Coast. [The storm will be slow to ramp up during the overnight hours and light winds will once again allow particle pollution levels to rise. Once the storm is in full force levels will clean out. So the forecast of moderate is for the overnight and morning hours of Friday. Expect GOOD air quality statewide from mid morning through the remainder of the day.]-- Forecaster: Webster
