Both the EPS and GEFS are building heights in the EPO space towards day 15, but it's a bit too far west. There will be a mechanism to get cold air delivery into Canada, but we will probably need to be patient here. Hopefully the -EPO is real, and the long wave pattern progresses eastward. Verbatim the mean trough will be in the western US with a west based EPO ridge, and with a +NAO, there will a tendency for a persistent SE ridge, and a storm track to our NW.
