There is a little more skill saying a pattern is unfavorable vs favorable, especially early in the season. A favorable pattern still needs the right track. So while patterns can look favorable, you still can't be sure of a low track within a 50 mile certainty to deliver, 4 weeks out.
However, A big ridge in the east on almost all guidance says to me that there is more confidence in saying a pattern is unfavorable. Whether the low tracks over ORD or SYR has the same effect for us vs having something pass at a favorable location with a good antecedent airmass. If that makes sense.
Again, not cancelling winter or even December, just not a fan of how things look heading into the beginning of the month. That has no bearing on winter.
