Forecast Discussion

Monday January 25, 2021 12:00 PM

Increasing clouds on Tuesday, as a weak area of low pressure moves in. Possible snow showers late day, with light east to northeast flow. Air quality should remain GOOD. Clouds and a chance of precip on Wednesday, with highs in the low 30s. Low mixing heights and light winds could allow fine particles to reach MODERATE around Providence, especially overnight. By Thursday, strong high pressure offshore will result in strong northerly flow, and some of the coldest air of the winter. Highs only in the low 20s. Good mixing will keep air quality very GOOD.
