Ozone readings expected to be GOOD through spring of 2025. Daily forecast is for fine particles.

Some stagnation on Friday should allow fine particles to slip to the low MODERATE range, with light NW winds, mostly sunny skies, and highs in the mid 30s. A deepening area of low pressure will bring clouds, some milder temperatures in the mid 40s, with showers and steady southerly flow. Air quality expected to be GOOD. Winds shift to the north on Sunday as low pressure exits, with sunshine and temperatures in the low 40s. Northerly flow results in GOOD air quality. NOTE: RI will not be experiencing any wildfire smoke from California.
