Main uncertainty currently involves how far north a warm layer
aloft extends Friday morning. The 12Z/23 NAM is most aggressive
with bringing such a warm layer farthest north, suggesting a
changeover to sleet/freezing rain for most areas south of I-90,
with some sleet mixing in even to or north of I-90. This
actually seems reasonable, given the anomalous warmth currently
located across the southeastern U.S., and also based on recent
model performance this winter with warm layers aloft.
