    Weather Forecast: Muggy, Patchy Fog

    Sunday Night: Muggy, patchy fog. Isolated downpour. Lows around 70.
    Monday: Partly cloudy, warm and muggy. Afternoon storms. Highs around 90.
    Tuesday: Mix of sun and clouds. Still humid. Highs in the 80s to near 90.

    (Published Sunday, Aug. 18, 2019)

    At 9:15 p.m., Severe Thunderstorm Warnings expired for northern Berkshire County in western Massachusetts, southern Bennington County in southern Vermont, and Litchfield County in northern Connecticut. These are in effect until 9:15 p.m.

    At 7:15 p.m., Severe Thunderstorm Warnings expired for south central Worcester County in central Massachusetts and southwestern Norfolk County in eastern Massachusetts; northern Windham County and northeastern Tolland County in northern Connecticut; and northwestern Providence County in Rhode Island. 

    For the second night in a row, storms rumbled across parts of New England, especially north and west of Boston. This comes after a day which saw temperatures spike to 90 through the interior.

    The downpours and storms will weaken as they move east overnight, with lows holding in the 60s to around 70 degrees. Locally dense fog will develop again, particularly near the coast and on the Cape and Islands.

    Monday will be much like today, in that fog will burn off to afternoon sunshine. An approaching cold front will then trigger a line of downpours and storms late day. Those storms will move from west to east as highs hit 90 in many spots. Combined with continued high humidity it will feel like it’s close to 100 at times.

    Tuesday will be mostly dry, with a mix of sun and clouds, as the front pulls to our south. It will still be hot and humid though, with highs in the 80s to near 90.

    Warm and muggy air lingers into Wednesday and Thursday, and both days will be unsettled again. That means more occasional downpours and storms.

    A new air mass finally arrives for Friday and next weekend, so expect more sun, cooler air, and lower humidity by then.
