As promised, the initial surge of much colder air will be arriving behind a system that crosses the Mid-Atlantic later tomorrow. The warm layer near the surface will be too significant for any snowflakes, so a few rain showers are in the forecast. Wednesday's temperatures will probably not get out of the 30s, and then the next disturbance races over the area on Thursday. The model data has been consistent with this system over the last few days and continues to indicate most of the moisture going just north of us. However, I wouldn't be suprised to see a few snow flurries/showers during the day. The Arctic freeze arrives on Friday, with daytime temperatures only in the 20s and overnight lows in the teens and single digits.
Things could get interesting later in the upcoming weekend. Our next system comes in from the west, and while several models don't make much of it, the European drives the system a little farther south in the upper trough, with more moisture involved. Below is a look at the European model forecast for surface features on Sunday morning. We can see the low pressure moving across Kentucky. By Monday morning, it's just off the North Carolina coast. While it's quite early to draw any conclusions, this could potentially mean some snow for us Sunday into Monday, so stay tuned.
