After a mild Saturday and a very rainy Sunday (1-1.5"), the weather in the Mid-Atlantic region will look much more like winter during the upcoming week with cold and snow in the offing. Much colder air will move into the Mid-Atlantic region by Tuesday and temperatures will be confined to well below normal levels during the mid-week time frame. By Thursday, an area of low pressure is likely to be moving over the Ohio Valley and then it should consolidate into a strong system near the Mid-Atlantic coastline. This system, combined with a strong, cold high pressure system to our north, will raise the odds for significant accumulating snow in the I-95 corridor from Thursday into early Friday; especially, north and east of the PA/MD border. The potential is certainly there for a widespread winter storm event as this scenario looks like a classic setup as it will feature a double upper-level jet structure with major Arctic air intrusion and a banana-shaped high pressure system sitting to the north. Once this strengthening storms pulls of the Northeast US coastline on Friday, bitter cold air is likely to follow into the Mid-Atlantic region at the end of the week. Stay tuned.
