    Weather Forecast: Early Precipitation

    Tuesday night: Hazy moonlight. Upper 20s to low 30s. Wednesday: Early sprinkles or flakes. Developing afternoon sunny breaks. 50. Thursday: Mostly cloudy. Afternoon/evening showers. 53.

    (Published Tuesday, March 27, 2018)

    A sunny and frosty start gave way to milder temperatures near 50 and increasing clouds today, all as even milder air approaches New England.

    Between New England and the milder air staged across the Ohio Valley is a round of mixed showers composed of rain, freezing rain and sleet. By the time approaching showers arrive overnight Tuesday into early Wednesday morning, some snow will be mixed in for the mountains, and light, spotty freezing rain showers may cause a few slick spots early Wednesday morning as far south as central Massachusetts, northern Connecticut and the suburbs north and west of Boston.

    It's not expected to be a high-impact event as those light mixed sprinkles and showers will depart early Wednesday morning, then clouds should give way to some sun by afternoon with highs eventually reaching the 50s in at least southern New England.

    Once the milder air arrives, it’ll stick around for at least a few days with highs in the 50s Thursday through Saturday.

    With the jet stream wind — the corridor of fast wind high in the sky that steers disturbances and separates northern cool air from southern warmth — flowing overhead this holiday weekend, we do see an elevated chance for some showers, but timing those showers will be key.

    Right now, our exclusive built-in-house guidance shows a 20-40 percent chance of showers Saturday and Sunday, respectively, but we’re not expecting any soakers at this point.

    Temperatures will gradually cool by the middle of next week, at the end of the exclusive Early Warning Weather 10-day forecast.
