    Warm and Cold Front Clashing

    Today (Tuesday): Rain fills in. Highs in the 60s.
    Overnight Tuesday Night: A few showers, patchy fog. Lows in the 60s.
    Wednesday: Humid, chance shower, evening thunder. Highs near 80.

    (Published Tuesday, Sept. 25, 2018)

    Cold air with wind from the northeast gusted over 30 mph, making for a brisk fall feeling Monday.

    Now, the same front that brought that cold is turning around and crossing as a warm front Tuesday and Tuesday night. Temperatures start Tuesday morning in the 40s to 30s in Northern New England.

    As the front moves by this afternoon, it drives warm air toward New England. The collision with our existing cool air means heavy rain from west to east early to late morning, respectively, with embedded afternoon downpours. Wind from the southeast may gust past 40 mph with downpours and possible thunder.

    Tuesday night is milder and more humid with rain and wind that will diminish to fog and drizzle.

    Wednesday, we are back on the warm side of the front, leading to a day near 80 degrees with scattered morning showers and afternoon thunder. Afterward, a cold front will bring a quick end to the exceptional warmth.

    Another disturbance may deliver Thursday night showers before what appears to be a good weekend ahead, and a persistent early fall feeling in our exclusive Early Warning Weather 10-day forecast.
