There are a couple of systems to look at the Thanksgiving week, but at least Saturday and Sunday, things look a little tranquil. Going into Sunday afternoon, we could have near 60-degree temperatures for Raleigh, North Carolina, low 70s in Savannah, Georgia, and back in the mid-50s for New York City.
An area of rain will spread from the Midwest to the Northeast Sunday into Monday. Then, colder air arriving behind the storm system could result in a changeover to snow for interior sections of the Northeast. Any snow accumulations are expected to remain on the lighter side.
