Only the 9th year on record that NYC made it to 60 degrees or warmer during the first week of February. First time ever after dropping to 2 degrees during the last week of January. The previous coldest last week of January temperature was 17 in 1988 and 1991.

All in the modern era except for two ( though even they are considered to be modern era using broader definitions; I know, someone will jump in to say no one kept records in the Stone Age. Save it. )

So what was it when we all thought mid January would be snowy for the coast or that this week was going to be cold up until a few days ago?

The MJO ruined it.  At this stage I would be utterly shocked if we aren’t below normal with decent snow chances 2/15-3/10 based on the MJO

But what about that tweet from Jason Furtado? The thing is I do see us getting snow but anyone saying guidance will be spot on after what we have been through this winter, I say give pause and not make definitives. At this point I’m unwilling to go much beyond a 5 day. We saw how drastically even the MJO forecast has been. What’s to say that won’t be the case again in a few days. I’m not trying to play Devil’s advocate here.

This was the warmest temperature ever recorded first week of February following 2 degrees or lower last week of January.

I know there's a lot of snow hounds on this board, present company included, but days like today make me yearn for spring and an abrupt end to winter right now. This weather makes you feel alive again.

It makes you feel alive in late March or April. In early Feb it makes you wonder what is going so radically wrong. And it's not just this winter; I've seen temps into the 60's, 70's, and last 80 in midwinter for quite some time now, going back a ways.....but i don't remember seeing them in the 70's or 80's very often, if at all.

Given that winter is mostly dead (maybe we get a storm or two) I'd vote just to have it be warm and dry the rest of the way....

Readings around the New York City area surged into the 50s today. Additional springlike warmth is on tap for tomorrow.

The SOI was +0.24 today. As the MJO approaches a low amplitude in Phase 7 or heads back to Phase 6, the historical data favors positive values. However, there have been some exceptions.

The Arctic Oscillation (AO) continues to rise quickly from its February 1 minimum of -3.537. Today's preliminary value was -1.977. The preliminary average for meteorological winter is -0.379.

On February 2, the MJO was in Phase 7 at an amplitude of 1.272 (RMM). That amplitude had fallen from the February 1-adjusted figure of 1.547.

There remains some uncertainty about the MJO's progression. However, as most of the guidance had indicated, the MJO's amplitude is now declining. There remains a distinct possibility that the MJO could fall to low amplitude or return to Phase 6 in coming days. Afterward, it should return to Phase 7.

Phase 6 at a high amplitude and Phase 7 at low amplitude typically favor a positive AO. As a result, the AO will likely continue to rise in the coming days. There remains strong ensemble consensus for this rise and growing consensus for the AO's reaching positive values in about 3-7 days.

Much this week will likely feature above to much above normal readings in the region. Before the week is finished, there is a possibility that the temperature could flirt with 60° in New York City. However, colder air should return during coming weekend.

There remains a possibility that a predominantly colder than normal regime could then lock in for at least a 2-3 week period, especially as the EPO is expected to go negative and blocking could redevelop.

Many record warm temperatures today across the Northeast with more to come, already outpaced the record cold and we have many days to go.

FWIW, this may be the first time that the EPS weeklies were the same as the CFS weeklies. Both forecasts are showing a gradual progression to colder with the MJO 8-1. 

Can’t post the EPS weeklies, but these CFS weeklies are the same.

A gradual progression is spring....

Weeklies are meh...shows some colder weather, but it's delayed until roughly 2/25.   The week before that is average to slightly below the biggest anomolies are in the upper midewest...the best deparatures locally are in early March, but it keeps pushing out and out and not really moving up in time.  Looks like a SE ridge trying to hang on too
