February 2022

[donsutherland1]

In the wake of the snow, sleet, and freezing rain, tomorrow will be fair but cold. Temperatures will rise no higher than the 30s across the region.

Overall, the closing days of February into the first week of March will be generally colder than normal. March could start with a sharp cold shot. A warming trend could develop afterward. The duration of this warming remains uncertain.

The ENSO Region 1+2 anomaly was -1.7°C and the Region 3.4 anomaly was -0.6°C for the week centered around February 16. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.90°C and the ENSO Region 3.4 anomaly has averaged -0.70°C. La Niña conditions will likely persist into at least mid-March.

The SOI was +7.59 today.

The preliminary Arctic Oscillation (AO) was +1.633.

On February 23 the MJO was in Phase 3 at an amplitude of 1.089 (RMM). The February 22-adjusted amplitude was 1.502 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 98% probability that New York City will have a warmer than normal February (1991-2020 normal). February will likely finish with a mean temperature near 37.1° (1.2° above normal).

we are going to experience a bit of a warmer pattern after this cold shot this weekend. there is an outside shot for a clipper/miller B around the March 1-3 period, but it's a long shot. however, the pattern does look to reload

we will warm up as the -EPO fires up and cold gets dumped into the west. however, the -EPO extends so far towards the pole that pretty much all of the cold air in the NH is funneled into SE Canada. the SPV is also going to come under some significant fire, and the weakening of the PV should allow for some blocking to possibly form. this would also help to drive the TPV southward into SE Canada

overall, this should allow for a ton of cold air to pool into SE Canada and for a broad CONUS trough to form once we finish the first week of March. New England is going to be favored here, but we should continue to have overrunning chances if Canada stays that cold. the sustained -EPO will bring Arctic air into Canada and the CONUS through mid-month, which is the most important factor for March snow

Don when is the AO going to get down to something more reasonable for wintry weather?

Sounds like more storms like this one even when the pattern is good....No sign of negative AO/NAO anywhere?  At this rate NYC and the airports may finish with below normal snowfall for March

I would say that's a -AO with all the positive height anomalies over the pole. there could be some ridging into Greenland too, and any bit of that helps

It’s tough to be sure. The wave lengths are shortening, so that adds complexity. I still suspect that we’ll see at least some accumulations of snow in March and that there might be a window of opportunity for at least a moderate snowfall.

The last 3 days of February are averaging 34degs.(25/44) or -4.

Month to date is  37.8[+2.2].        February should end at  37.4[+1.5].

Reached an unexpected 46 here yesterday.

Today: 34-38, wind nw. to w., few clouds, 30 tomorrow AM.

First 10 days of March   41(35/46) or +2 and snow less.    GEFS says only 60% chance of at least 1" in the next 384hrs.

Snows are over.    70's and SPF-15 OK for now.

25*(54%RH) here today.      30* at 11am.      32* at Noon.       34* at 1pm.       38* at 3pm.       Reached 40* at 4pm.        36* at 6pm.

Pattern as outlined by others previously- unreliable UKMET has 6" for the I84 corridor this coming week. Definitely for the I84 folks, do not want to be dismissive about this pattern. Also, am not seeing lots of warmth this week til maybe the 6th. Shortwave dropping se from Canada are the culprit.

[bluewave]

A record breaking 7th warmer than average winter in a row for our area. The SE Ridge or WAR has been a dominant player since the historic December 2015 +13.3 departure. So the limited colder departures end up further west away from this persistent 500 mb height anomaly.

So a warm December, cold January, with a big snowstorm, blizzard for Long Island, slightly above normal February..Overall below average snowfall.We'll have to see if we can get near normal snowfall in March

Took a brief walk on my property this morning - my sleet pack is literally a glacier which can support my 200+ pounds of weight without even caving in.  Haven't experienced that since i was a kid.

The snowfall distribution this winter was the opposite of last year with the progressive +AO pattern. Coastal sections did much better than interior areas this winter. Last winter the south based -AO allowed the storms to tuck in near SNJ with heavier snowfall further to the west.

Every storm was near coastal SNJ which I found interesting.

It was only for the big events....for one thing there werent any extreme events between Feb 1983 and Mar 1993 and then it was sporadic (just Mar 1993 and Jan 1996) before the madness that began in the 2000s lol.

Mar 2001 would have sent this board over the edge

One would think a +AO would favor inland areas.....wasn't this the case during the mid 80s thru early 90s?  It was all about N/W

Most of the sub forum is well below normal as that blizzard only produced big for immediate coast

 

In particular HV had a terrible year for snow.

Very similar to 2015 in snow gradient… Not quite as extreme

We have to view the +AO configuration this winter in the broader context of what the other telconnections were doing. The strong Janaury +PNA  put the trough in the East. But the +AO prevented the upper lows from closing off until the surface lows got east of the benchmark. Last winter the upper lows were closing off early to our SW with the strong south based -AO. The surface lows all tucked in near SNJ. So Binghamton is currently in 2nd place for lowest seasonal snowfall through the 25th. While ACY is currently the 10th snowiest on record. The places were reversed last winter. BGM was 16th snowiest with  ACY the 17th least snowiest.

That's an excellent way of looking at it-- we need to view teleconnections together, not in isolation.  And we further have to subdivide them into north vs south and east vs west based.  But here's another thought.  Is the NYC area just in a bad area for storm tracks....we saw this in the 80s too- there are two predominant tracks for storms, one is south of the area and the other is north of the area.  We've seen this in a few other recent winters too, where places both south and north of us see less snow in individual storms than we do.  Maybe the NYC is just a bad area for snow unless everything lines up perfectly?

 

[donsutherland1]

Morning thoughts…

It will be partly to mostly sunny and cold. High temperatures will likely reach the middle and upper 30s in most of the region. Likely high temperatures around the region include:

New York City (Central Park): 36°

Newark: 37°

Philadelphia: 41°

Tomorrow will be fair and milder.

Normals:

New York City: 30-Year: 44.6°; 15-Year: 44.8°

Newark: 30-Year: 45.6°; 15-Year: 45.9°

Philadelphia: 30-Year: 47.0°; 15-Year: 46.9°

The problem is people are trying to make every moderate size event a once in a lifetime event.

If you saw 2015-2016 you likely won’t see that again.

That is the kind of storm you tell your grandkids about. I’ve heard stories about cars being buried in snow in NYC and didnt believe it until I saw it with my own eyes.

And yes the storms are getting bigger and more frequent, but the set of circumstances that allow a perfect storm like that are only going to occur once twice or three times in a human lifetime.

People don’t want to hear that, particularly in the sensationalist age, but it’s the truth

Thats right and actually for me, Jan 2016 is in its own category.  There's only a few that rank that high for me and it's Feb 1983, Jan 1996, Feb 2003 and Jan 2016....so basically once a decade.  That's my full list of 20"+ storms (my minimum for HECS) and one of them was a 30"+ storm (BECS in my classification system).

4-6" moderate

Thanks Don, given the depicted look of the ensembles I would not be shocked, but surprised if at least parts of the forum do not see more snow. 

ORH wxman in the NE forum had a great write up on the upcoming pattern in the March thread quoted below....

"The PNA index just measures where the height anomalies are within the PNA domain loading pattern. So because we have higher heights out toward the Aleutians and lower heights over western Canada, it’s going to produce a -PNA (RNA) number. It doesn’t mean the PV has to get sucked down into Washington and Oregon like it did back in December during that obscene pattern. 
 

The PV being over Hudson Bay will help with overrunning threats that might otherwise be cutters. You can see though how the mean trough is further east by the end of EPS run though. It’s more sitting over the central US instead of further west so it would give us a better shot at a Miller B. "

It was only for the big events....for one thing there weren't any extreme events between Feb 1983 and Mar 1993 and then it was sporadic (just Mar 1993 and Jan 1996) before the madness that began in the 2000s lol.

Mar 2001 would have sent this board over the edge

I mean extreme emotional responses to mundane events. "Waaaahhhh I'm not the one getting more than 4"..."

That's an excellent way of looking at it-- we need to view teleconnections together, not in isolation.  And we further have to subdivide them into north vs south and east vs west based.  But here's another thought.  Is the NYC area just in a bad area for storm tracks....we saw this in the 80s too- there are two predominant tracks for storms, one is south of the area and the other is north of the area.  We've seen this in a few other recent winters too, where places both south and north of us see less snow in individual storms than we do.  Maybe the NYC is just a bad area for snow unless everything lines up perfectly?

 

You're just realizing these two things now?
