I also feel like these pattern changes take time to take shape so even if there was a potential threat window early in the blocking pattern change, more often than not, those shift right. Snow in the first part of December is really hard to make happen for most in the forum (especially in a Nina). So even if the more favorable pacific is delayed until later in December (and hopefully links up with a favorable Atlantic), it’d be much better climo for the 95 areas.
Level headed thinking and snow don’t go hand in hand in the mid Atlantic though…
