Winter begins with high temps near 50 around Philadelphia, tracking rain on Christmas Day

Sunday kicks off the official start of winter, but it'll actually feel more like fall.

Temperatures will climb into the upper 40s and some spots could even hit 50 degrees.

Overall it's a quiet, partly sunny day before winds pick up later tonight as a front moves in.
