Enjoy your outdoor activities.
Other Pollutants:
OZONE - 39 Good
Some lingering clouds and chances for precipitation are expected both Wednesday and Thursday as a cut-off low pressure system spins over New England. Some breaks of sun over this period will lead to at least some ozone production but given a clean northerly flow expect generally Good ozone levels across the state. The low pressure system will slowly push away from the region heading into Friday. A bit more in the way of sunshine will allow ozone levels to climb but will only reach threshold Good to low Moderate levels given a clean residual air mass and unseasonably cool temperatures.
