Strengthening low pressure system will progress up the Atlantic Coast tonight and Wednesday. Another low pressure wave will arrive with a few snow flurries Thursday. Mild trend continues into the weekend.
Rain showers or mixed precip will spread into the area from the east this evening. Strong southern air flow will bring plenty of warm air and will limit snowfall amounts for most of the low lying areas Tuesday night. Still expecting temperatures to cool enough to allow rain/mixed precip to eventually change to a very wet snow early Wednesday morning. Look for total snowfall accumulation between 2-4 inches for most of the lowland areas. This would be just enough for snow-covered roadways to create delays Wednesday morning. More significant snowfall of 8-10 inches will be realized in the eastern mountains of West Virginia, where colder air will facilitate a faster transition to snow.
Cold air will struggle on the backside of the front and mild temperature trend will continue Wednesday. Highs will manage to reach the mid to upper 30s so expect mixed precip for part of the day of Wednesday.
Winds out of the northwest Thursday will allow cold air and a few light snow flurries to sink into the region. Despite the cold air moving in, daytime highs will only be a degree or two above freezing. Once again, significant snow accumulation will for the most part be limited to higher elevations.
A pair of weak low pressure waves will arrive Friday and again this weekend. Some light accumulations are possible with those systems but the mild temperature trend will continue through the weekend. Daytime highs will be in the upper 30s/low 40s this weekend. Precip will likely be rain or mixed. More refined forecast to come...
