This is going to be a fun week of tracking. Hopefully people just keep in check though and understand the caveats that will apply and don't live-and-die by each subsequent model run. Models struggle big time with confluence so with that alone it won't be surprising to see wild changes from OP run to OP run. But until we get inside D5 the only thing that will matter is the evolution of the pattern. SLP tracks, snowfall maps mean squat. Just b/c an OP run may show no storm verbatim won't mean the storm is "lost" and just b/c an OP run may show a Georgie orgie blizzard, doesn't mean it's a lock.
