    3. Bitter cold and wind Sunday and Monday
    4. Snow chances vary by region but icing could be an issue for many

    Winter Weather Advisory

    This morning many counties North and West of the district were under a Winter Storm Warning. However, with time, it was becoming more evident that the threat for major winter weather was staying farther north into PA and west into Cumberland Maryland. Therefore the initial Winter Storm Warning was canceled by the National Weather Service. But parts of the area like counties along I-81 and into Frederick County remain under a Winter Weather Advisory until 6 am Sunday. This includes the potential for snow, sleet and ice. Far western Maryland has the best shot at accumulating snow ranging from 1 to 3 inches and .20” of ice. For many, the farther south you go, it will be just a cold rain event.

    Could We See Flooding?
    Rain showers are expected to begin this evening after sundown and stick around through about 9am tomorrow morning. The Rain will be heaviest overnight. At this point the flooding potential is not wide spread. However a frozen ground combined with snow melt and new rain we could be talking some flooding. Were we see heavier pockets there could be isolated flooding as well. Expected rain totals are ranging from about 1 to 1.5 inches.

    Warm Air Surge

    Your Saturday night will be warmer than your Saturday believe it or not. A warm front will lift from the south into our region prompting a surge of relatively warm air to move in overnight. Temperatures will begin to rise around 11 pm from about 40° to near 50° just around sunrise. This warm air is also the reason the precipitation will remain rain tonight and not be snow. The warm air will be short lived as colder air marches on.

    Cold Air Plummet
    The warm front moves out of here tomorrow morning and a flood gate opens ushering in some of the coldest air we have felt in a long time. The drop will begin around 9 am Sunday morning. The temps will continue to fall through the day with evening numbers in the 20s and Sunday night lows in the teens and single digits.

    Are there any Snow Chances Sunday Morning?
    The chance for Sunday morning snow is rather small but present. It all comes down to timing. The wrap around moisture from the storm could line up with the cold air rushing in early Sunday morning. If this occurs there is a chance for some snowflakes/light snow shower throughout the region but it will be so quick that no accumulation is expected.

    Bitter Wind Advisory
    Advisory from 11 am Sunday until 7 pm Sunday
    It’s one thing for the temps to drop into the single digits but for winds to push that cold air in at nearly 45 mph gusts from the northwest, well that just bites. Wind gusts will start around 20 mph early Sunday then, reach 50 mph by Sunday evening and continue to gusts around 30 mph into Monday morning. This means the wind chill, what the temp actually feels like, will range from the teens to 10 degrees below 0 Sunday into Monday morning. The wind gusts could also cause damage so be careful.

    Will all that Rain cause Icing?
    A flash freeze or just icing for that matter is a valid concern based on the rain we will receive tonight. Even though the wind will sting it’s actually working in our favor. With winds gusting so strong all day Sunday, we will see some of the rain that fell, dry up. Where there was ponding and puddling will be more of an issue and as temperatures fall below freezing by Sunday afternoon we could definitely see some icing taking place. This means road travel should be impacted, especially Sunday night and Monday morning.

    Monday will actually peak in the teens and near 20° in the afternoon. While there will be plenty of sunshine it will still remain bitterly cold as winds continue to gusts up to 32 mph and wind chills remain in the single digits.
