No thread from myself until at least 830AM for short fuse snow squall gust 40-45KT even 11A-2P Pics and NNJ and 1P-3P NYC-CT.   Slightly less modeling support than yesterday though I think it will happen. 

No thread on Friday til at least tomorrow afternoon... a little concerned the ensembles les are favoring I84 for decent snow.

NYC currently running +6.3 for the first 2 weeks of January. This is followed by colder temperatures this week. Then another warm up to close out January. So the month should finish solidly above normal.

I'm sure you saw this as well, a number of mPING reports out in western PA of limited visibility in squalls along with accumulating snow so it'll be interesting to track this morning. I do see though what you are saying about a little less support on the models for around here though.

It’s easier to do temperature longer range than snow since snowfall forecasts aren’t reliable until we get to the under 72 hr mark. With the record Arctic outbreak to our west, we would be much colder this week if the flow wasn’t crossing the record warm Great Lakes. But highs near 32° in NYC and lows around 20° will feel much colder this week with how warm it has been. The wildcard for the forecast will be what happens with the storm later in the week. I will leave that to the shorter term model forecasts. But if we can lay down some snow cover and get a NNW cold air drain down the Hudson Valley, then NYC has a shot at dipping below 15° or maybe even 10° before we warm back up again later in the month.

Here. I dont care about KC haha. This is run of the mill winter time “cold” for NYC. Nothing Arctic about it for us.

Who wants arctic air ? I rather have it just cold enough for snow.

Enjoy Tuesday and next weekend before it gets mild for a brief time.

Today will be the 700th consecutive day on which New York City's Central Park has seen less than 1" daily snowfall. A system could end the streak on Tuesday.

At this point, I kind of want it to go until next season just so that we break 1,000 and everyone loses their minds and the media goes HAM with the stories.

If CPK is going to be an UHI along with a poor pattern, we may as well be entertained.

I think Friday they'll finally break it

We always want Arctic air nearby to guard against mixing issues near the coast and for the retention of snowpack once the storm is past. Examples of single digit temperatures and double digit snowfall would be 1-4-18, 2-17-03, and 1-7-96. That’s not to say we can get great snowstorms with the right track and just cold enough. We have had plenty of those over the last decade. But Arctic air nearby is a nice insurance policy to have especially near the coast. It’s good to have but not always necessary. I personally don’t mind a great snowstorm that melts in a few days.  But I know there are many here that don’t like that.

It will be tough to keep the streak doing through this week. Even if Tuesday's event falls apart, there's another shot Saturday.

Archambault event if everything comes together like you said.

The potential is better, at least from this far out. There's a risk that it could wind up becoming a January 30-31, 1987-type event if the trough exits a bit faster than currently modeled. Were that to happen, eastern New England would be favored and New York City and southward could miss out on most of the snow. Long Island could still get brushed. During that event, Boston picked up 3.9" of snow, NYC had no measurable snow, and Philadelphia saw 0.4". There is a significant difference from 1987, as colder air should be available this time around.

January 30-31, 1987 500 mb anomalies:

What we worry about with arctic air is suppression, an out to sea track.  It seems as though it can indeed be "too cold to snow" if the arctic air suppresses the storm to our south.  This was spectacularly the case with the first storm in February 2010, I'll never forget how close we were to having an HECS.  I would much much rather have a foot of snow followed by an inch of rain (or even moreso an inch of rain followed by a foot of snow like we did in the final storm of February 2010), than missing out on an HECS by 50 miles.  In many ways that first February 2010 storm was much more painful than even March 2001 was.

Not alot of talk about a possible snow event next weekend compared to other subforums .

This because they buy the GFS.  I dont think the GFS is worlds best model around here.  Canadian is better and it hesitates next Friday.  Also, need to talk about today and Tuesday first.  Then whatever we get after that is icing on the cake.

Not threading today, at least not yet. Too much melting much of the NYC subforum I95 east but its going to happen with a burst of snow (rain to snow LI) and winds during or within 2 hours after CFP, gust 45-55 MPH with iso power outages.  Will look at this more closely once it gets out of the Poconos at 1130A.

I think that first storm was suppressed due to the confluence and overpowering -5 SD -AO. There really wasn’t much Arctic air around in Fenruary 2010. NYC only dropped to 17 which is pretty mild for February minimum temperature standards for us.
