Many parts of our far northern and western suburbs will enjoy a White Christmas thanks to the 1-2 inches of snow that fell today. Elsewhere, it was mostly just a sloppy mix that amounted to bare ground. The precipitation winds down this evening, to be followed by cloudy, foggy conditions into Christmas Day. Christmas afternoon offers partial sunshine before the next storm approaches with more mixed precipitation concerns.
Through Tonight: Rain and sleet, except sleet and snow (perhaps ending as light rain or drizzle) in areas under the winter weather advisory (see above), end between 6 and 8 p.m. from southwest to northeast. Then it’s cloudy with patchy fog. Lows range from near 30 in the colder suburbs to the mid-30s downtown. Please use caution traveling in the winter weather advisory areas due to snow and slush on some roads and possible re-freezing.
Christmas Day: Cloudy with areas of fog in the morning, with partial clearing into the afternoon. Skies should eventually turn partly sunny with highs 40-47 (colder suburbs to south and east of the city).
Two more rounds of winter weather this week?: A powerful storm system - which could trigger a serious severe weather outbreak in the South Christmas Day - moves into the area Boxing Day (Wednesday) with another round of mixed precipitation possible. A winter storm watch has been posted for our far west and northwest areas, including Frederick, Hagerstown, Martinsburg, and Winchester - for the potential for significant snow and/or ice accumulation. In the immediate metro area, a brief wintry mix is possible before changing to heavy rain.
Then, another storm could affect the region this weekend, with the latest models suggesting snow could be the dominant precipitation type- though this could change. We will have a more detailed look at both storms tomorrow.
