Yes, I felt bad for JM, that was the most ridiculous rain snow line I have EVER seen!
Two other ones which were interesting were in the January 1994 ice storm and VD 2007, where the ice line was oriented to our east so that Oceanside was all frozen while east of there changed to rain.
The March 1993 superstorm also had interesting snowfall amounts-- Oceanside and points west were 10-12 inches while amounts drastically dropped east of Oceanside.
