I can confirm changing from IAD-EWR to IAD-JFK on a perfectly clear day for air travel in the northeast, coincidentally also in December. As previously stated, this doesn't seem to be standard procedure. However, in the new environment, every outcome is equally as possible as it is impossible, depending on which agent you speak to.
