    (Published Monday, April 16, 2018)

    On Sunday, we set records for cold high temperatures in the 30s, and even a record low of 12 degrees in Caribou Maine. We also set records for the most snow and sleet accumulation on April 15.

    That continued into Monday morning with a layer of freezing rain and ice, much more like February than April.

    As a whole for the lower 48, the storm passing New England on Monday is the highest impact the storm for the nation all winter or spring.

    The heaviest rain will continue through 7 p.m. Embedded thunderstorms are possible.

    Before the downpours arrived most areas received 1 to 1.5 inches of rain. Through 7 p.m., an additional 1 to 3 inches of rain is likely.

    Flash flooding is a concern. Already flash flood warnings have been posted. Keep an eye on the smaller rivers and streams which react quickly to heavy rain. NEVER drive through flood waters. Downstream, around New York City, first responders have been busy conducting water rescues.

    As the heaviest rain moves out, it is possible that we climb into the 50s before the cold front moves through. We aren’t done with the rain just yet. Although most of the night will be dry, we will see additional showers Tuesday afternoon and Wednesday afternoon. This unsettled pattern will persist into Friday.

    Nicer weather will make a return by the weekend. Both days should remain dry. With the help of the sunshine, temperatures will likely climb into the mid- and upper-50s both days.
