        Storm Watch: Inconvenient wet weather this evening, temps take a slight tumble

        A series of minor disturbances bring rain, snow and then bitter cold back to the region.

        A small, quick-moving disturbance is sliding rain through the area tonight. It doesn’t look like a good soaking. Just enough wet weather to have windshield wipers on intermediate or slow, and streets to be a little slick. Showers will exit quickly off the Jersey Shore after midnight and clouds will slowly begin to dissipate during the overnight hours.
        By daybreak, the sun will once again be center stage. As the storm passes, the winds will change direction and blustery winds from Canada overspread the region for Thursday. As a result, temperatures tomorrow will be cooler than the last few days, but just slightly milder than normal. (Normal high is 43) Thursday’s forecast high is 45.
        Clouds will begin to collect again by Thursday evening. Forecasting eyes will be on a “clipper” system dropping into the region from the Great Lakes. There are a few meteorological issues with this system. And here is why I think expected snowfall will be limited.
        1. “Clippers” are fast movers and usually don’t have a lot of moisture to work with. No different with this storm.
        2. As the main piece of atmospheric energy unravels over the area a secondary storm is expected to develop. This energy transfer happens too far south.
        3. The coastal storm doesn’t steer up the coast. Instead, it travels, fairly quickly, from the outer banks of North Carolina to Nova Scotia. That storm path is not ideal for accumulations.
        Will it snow on Friday? I do believe it will. But the intensity of snow and how much moisture in the air is going to be limited, therefore limiting the amount that could possibly collect. We should be prepared for snow showers, or in this case, let’s call them “festive flakes.” Accumulations will be manageable and there should be very few surprises. Just a small snowy inconvenience for some.
        This storm will lack winter precipitation but it will make up for it by unlocking very cold air from Canada. Saturday and Sunday the skies will be sunny the winds will be from the north-northwest and the air will be 10 to possibly 15 degrees below normal. It would not surprise me one bit if temperatures Sunday into Monday don’t get to 30 degrees for a daily high. The winds make it feel colder.
        Sunday and Monday morning wind chills could be in the single digits to near zero.
