Over the last few hours AA canceled a couple of more JFK/LAX flights. #3 (11:55a) and #117 (1:45p) are now canceled, leaving 4 afternoon flights out of 9 direct flights open.

The first flight #118 from LAX is also canceled even though it arrives around 3p. I think the same plane that goes JFK-LAX also goes back, so it may just be availability.

It looks like the weather will improve starting at 6am, but considering that severe-condition forecast has been extended to most of the night it may continue into the morning. My assumption is that if not for the new regulations, they would have taken the risk in not canceling, and let more flights out of JFK early this afternoon because the sever conditions didn't start when scheduled.
