Saturday is a day worth paying attention to air quality for sensitive groups. Ozone expected to be high MODERATE for the southern portions of the state, low MODERATE around Providence, as full sunshine, light westerly flows, and limited mixing allow for ozone development. Temperatures into the upper 80s. Fine particles MODERATE around Providence, upper GOD elsewhere. On Sunday, it looks as though steady straight southerly flow and mixing should keep ozone in the low MODERATE range statewide, with fine particles upper GOOD. Highs again well into the 80s, cooler coastal. High clouds filter in late day. A cold front will bring clouds, showers, and even stronger SSW flow, which should bring air quality issues to an end, back to the GOOD range. A good chance of showers or even thunder, with highs dropping into the upper 70s.


Air Quality Guide for Particle Pollution

Air Quality Index Levels of Health Concern Numerical Value Meaning
Good 0-50 Air quality is considered satisfactory and air pollution poses little or no risk.
Moderate 51-100 Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Unhealthy for Sensitive Groups 101-150 Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Unhealthy 151-200 Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
Very Unhealthy 201-300 Health Alert: Everyone may experience more serious health effects.
Very Unhealthy 200-301 Health warnings of emergency conditions. The entire population is more likely to be affected.
