Storm Threat Dec 26-28 Period

I thought it was at least post-worthy to note that the cpc D+11 analog composite lists a KU storm (December 23-25, 1966) as the top analog while the D+8 composite lists the same storm as the second analog.

The D+8 composite also lists another KU storm (December 19-21, 2009) as the eighth analog.

I don't know how to interpret the charts, so I'll post them here for more educated posters to comment upon if they so desire.

do you think having it track further south like the 18z has it will help the second storm be more frozen for us?

It's a week out and it's the GFS and it's the first GFS run (I think) to have shown this type of solution in the non-truncation (pre-192 range) so I'm applying a healthy grain of salt to my expectations on this storm. ;)

That said, a weaker primary track is going to prevent as much mild air from getting in and if the secondary develops down near DC we should have a pretty decent shot at some frozen precip. The track isn't necessarily farther south on the primary...it still gets to just about Detroit before it pops a secondary (which the 6 and 12z were not doing). It helps it's only around 1000 and not 990 at its strongest....that makes a big difference.

Also, to add to this, the 18z gfs has a much stronger and expansive high than the 12z. Secondly, it had a stronger and further south 50/50 low which fought off the the higher hgts along the east coast and created better confluence.

Even if the primary goes inland we could still be looking at a pretty significant ice storm. The CAD and 2m temps being shown on the GFS this far out is a pretty significant signal that ice may be an issue with the 27-28 storm.

I wouldn't make any comment on 2 m temps modeled by the GFS this far out. It seems that to get a "good" ice storm we typically need some really good cold entrenched beforehand, which doesn't seem to be the case this time.
