Discussion
A cold air mass will push into the region later today and tonight riding in on increasing northerly winds and all backed by strong Arctic high pressure building into the southeastern part of Canada. It remains very cold on Saturday and Saturday night and then attention will turn to our south for the second half of the weekend. Low pressure will develop by early Sunday morning in the southeastern states and this system will then make a move to the northeast and it’ll encounter an Arctic air mass that will be quite reluctant to give up its ground. As a result, a significant snow and ice event is likely to take place across interior sections of Georgia and the Carolinas on Sunday morning and mid-day. After that, moisture from this storm will push into the Mid-Atlantic region and with the cold, dense air in place, a period of snow and sleet is likely on the front-end in the Philly metro region. Early accumulation estimates are on the order of a couple inches - perhaps in the 1-4 inch range with the highest amounts to the northwest, lowest amounts to the southeast. The snow and sleet will likely changeover to rain later Sunday night with some icing still possible N/W and the winds will get quite strong. Coastal flooding is possible with high tides Sunday night/early Monday and damaging wind gusts are possible along coastal sections.
