Pattern Change In The Next 7-10 Days?

Lately, we have been looking for a possible pattern change in the next 7-10 days.  One thing that has me hopeful is the MJO. It looks to go into phase 1.

Phase 1 is an excellent phase for the NE/MA if you're looking for cold/snowy weather. You can see the 500mb composite for Phase 1 for December below.

You can see there is troughing near the Aleutians in the NE Pacific. This usually teleconnects to a +PNA. The +PNA is a ridge over the western states. Over the east, there is a trough. You can also see a -NAO, with the block WEST based as it's over Southern Greenland. This pattern is usually good if you're looking for an east coast snowstorm.

We might be looking at a possible storm in the Dec 15-22 period. Whether it's an east coast snowstorm remains to be seen, but if this pattern actually verifies, the possibility increases.
