And then blocking may reappear as it often does late in seasons that featured blocking early. No guarantees, but it's not so simple. Heck, 95/96 was a Niña and had no problem being cold and snowy in February for many on the east coast.
The key to February is that all long range guidance has precip AN all along the east coast. So warmer temps and AN precip in February is conducive to snowfall.
Looks like the first batter is coming up to the plate at the end of the Icon run.

Ensembles have the best look for a 5-7 day period I can remember. Hopefully they don't lose it. 6z EuroAI has the 2nd wave with the snow again. Biggest concern for me remains cold overwhelming but that's more based on seasonal pattern/persistence.
