63 & 76 yes. 53 & 76 no...for east. 

 

But ORH_wxman had some good years for cold DEC posted above.

Again, it's really about timing. I have a hunch we see some cold in spells in DEC. All my comments were based strictly on my analog years. Analog blend sdo not always pan out.

A good outlook will use analog blends as a tool but pity anyone that ignores trends & makes a winter outlook based "solely"on analogs. That's why its smart to wait until Thanksgiving. :)

I certainly hope for some wintry periods in DEC! It just seems fitting with the holidays

Yes classically we seem to get our snowy periods early to mid December while late December is our "thaw" period.  I could see that happening.  An early snow appetizer or two Dec 1-20, then the thaw could be like Dec 20-Jan 20, with the main course of winter snows to come Jan 20 to Mar 20.

Corresponds well with the period of max occurrence of noreasters.

Last year's thaw froze dees nutz off

Last winter, all I remember from the early part is a huge windy snowstorm in January that was one of the longest duration of blizzard conditions I have ever seen (a true whiteout for 6 hours!) and then it somehow got to 80 degrees in February with bugs showing up everywhere, and then it went back to stormy in March and eventually the greatest late March snowstorm I've ever seen and then another snow storm to start April that snowed out the Yankees home opener.  All this was followed by literally the worst allergy season I've ever had, I had to take allergy pills for 2 months after the weather started to warm up.  I couldn't breathe- even inside my house!

And then the heat and humidity started in early June and by then my allergies were finally gone.  We had another allergy season in the fall but it was much shorter as the heat and humidity finally came to and end in mid-October.

Pattern didn't flip until around MLK in 2005 as well. Though unlike 2014-2015, we were able to sneak a couple snow events in before that in early January and late December even though the pattern wasn't that great. 

 

Farther north in 2005, we didn't record a 4" storm until Feb (late Jan blizz was a 2" graze.)  Of course, that first 4+ was a 21" dump with thunder, and we had 60" from 2/10 thru 3/12.

I wouldn't at all be surprised to see a similar outcome to Dec 2004...it probably won't be an early shut out like 2014, nor as furious a second half, obviously. (duh)

Beyond the analogs, the prospects of a stratospheric vortex disruption are becoming more likely in the next few weeks. This could allow for some cold air to filter in during Dec. 

Why?

Admittedly, I have not been tuned in much over the past 10 days or so bc of the move, but strat. was pretty chilly last I saw...

He was just cancelling winter last week. :lol:

This is what happens when allow one indicator to inform your entire "outlook".

The more prudent course of action would be to consider the SAI while formulating thoughts regarding the early season behavior of the polar fields.

Vertical wave activity flux is predicted to have a large uptick in the next week or two, with models beginning to show the possibility for a strong Scandinavian block, reinforced by consistent wave breaking in the North Atlantic. Obviously this is predicted, but model skill in terms of the stratosphere has been shown to be more accurate at longer lead times compared to tropospheric forecasts. However, there is little to no correlation between stratospheric vortex disruption and cold air in the US. Most of the correlation lies in Siberia. Just something to monitor, no guarantees.

Judah is picking up on what I'm talking about, but this is in no way related to SAI and he never mentioned it was either.

No, obviously not because its too early for that to have manifested itself. However his winter outlooks are based entirely on the SAI, like I said.

Grain of salt.

Yes, you are correct about Judah's outlooks. Just be on the lookout. I'm sure we can all be happy about the chances of a weakened vortex.

Yea, I'm not saying that the modeled changes in the stratosphere won't happen....but just advise caution until we see the whites of its eyes.

I don't see an impetus for it, so there is reason to be skeptical unless there is strong climo support....which there isn't at this juncture of the season.

I guess you are disregarding what I provided. What leads you to believe there is no impetus?

I'm not disregarding anything. I don't take modeled stratospheric changes as gospel because they are often rushed and/or greatly exaggerated.

Its akin to seeing a days 10 HECS modeled without teleconnector convergence.

Why trust it?

Same crap last January when so many folks were smoking the blocking pipe, which had no basis.

Poof it went...then I heard the same crowd criticize me for not budging on the epic March idea.

There are multiple reputable Mets ion twitter talking about the possibility of it being legit.
