The 12z GFS has a strat split/reversal up at 20mb at day 11.GaWx is right a technical SSW is a reversal at 10mb but anything above 30mb can shake up a pattern from what I've read.Carry on.
Hmm,looked like the Canadian today was trying to go all 1899 late in the run.Every now and then you get a run from all models of a wicked cold shot but I'm not sure how far southeast it gets.
Euro and EPS look pretty good at day 7- 8,even the GFS is similar with the low placement it's just too warm for frozen at the moment.
MJO looks very favorable in about a week,(p8,p1)AO is still negative,and the NAO ticking to neutral.Time to track.
