Forecast Discussion

Monday November 19, 2018, 2:30 PM

A wave of low pressure will sweep through on Tuesday, with clouds, showers, high temperatures in the 40s, and northerly winds. Light winds and lower mixing heights could allow fine particles to approach MODERATE, especially around Providence. Another weaker wave of low pressure will impact on Wednesday, with clouds and only some light showers before passing through late day. A blast of bitterly cold air is expected on Thanksgiving, with highs only to around 20F, northwest winds, sunshine, and GOOD air quality.
