When's the cold and snow coming?

Yeah, good question.  A couple weeks ago, I would have said now.   But things haven't panned out that way.   A couple of atmospheric conditions/indexes, the North Atlantic Oscillation (NAO) and the Arctic Oscillation (AO) are stubbornly remaining positive.   As a result, very little Arctic air is allowed to remain in the Eastern North America region and no storms of note are coming up the eastern seaboard.

But there is hope.   As indicated in the links above, these indices are predicted to approach negative territory in a week or so.   So I think the seasonal temperatures will come next week.  As for snow, that'll depend on the storm track and the arrival of cold.   So it's looking like late Monday/Tuesday where we may get some snow...but not a lot.

For readers from Southern Ontario (I know you're out there) in the typical snow belt regions, look for significant Lake-Effect-Snow events happening late next week.
