The last 3 days of January are averaging 35degs., or 3degs. AN.

Month to date is  +7.2[39.6].        January should end at  +6.8[39.2].        The first 13 days of February are averaging(0Z, GFS)36degs., or 3degs. AN.     2" of Snow this weekend.   EURO is just ugly and the CMC has snow where the GFS has T in the 50's.      The (06Z GFS) is averaging 35degs., or 2degs. AN with no snow until the 12th.

34* here at 6am.        33* by 8am.         40* by 2pm.       42* was high at 4pm.

3 days of mid 50s next week??

Let’s stick a fork in this winter already enough with this garbage

Just enough already

I am also frustrated with this garbage winter thus far.   But ..not willing to throw white flag  up until March 15 ..after that date ..yes you can get snow but for coasties and city unless its a night time event  or a huge storm bringing in its own cold air gonna be a sloppy mess of a storm. Sooo lets wait and see what happens..

I wish I can move but I have a good job in the city.

I would definitely  move to  Syracuse burbs.

Eh I’ve thought about staying here but based on cost of living even making less, lifestyle is far better elsewhere. See what the earliest you can leave and collect some pension. But I just really hate our springs and cost of living. My goal is New England, upstate, or south. Right now south is winning, especially since we do travel a lot.

What will very likely become the 9th warmest January on record in New York City is now concluding. February will start mild with the first week of the month winding up warmer than normal in the Middle Atlantic and southern New England areas. In addition, little or no snow is likely in New York City, Newark, Philadelphia, and Washington, DC into at least the middle of the first week of February.

Colder air could return late in the first week of February or just afterward. However, Arctic air is unlikely.

As long as the Arctic Oscillation remains strongly positive, the risk of widespread significant snow (6" or greater) from Washington, DC to Boston remains low. Since 1950, there were 11 storms that brought 6" or more snow to 2 or more of the following cities: Boston, New York City, Philadelphia, and Washington, DC. Just 1 such storm occurred when the AO was +1.000 or above. Therefore, through most of the remainder of January, the greatest risk of moderate or significant snowfall will likely exist for central and upstate New York and central and northern New England. Boston would have a higher probability of receiving a moderate or significant snowfall than Baltimore, New York City, Newark, Philadelphia, and Washington, DC.

During the coming weekend, a storm moving offshore will likely intensify rapidly as it moves into the waters off New England. However, little or no snow is likely for the New York City area.

Based on the latest guidance, the likely seasonal snowfall distribution through January 31, will be < 20" at Boston; < 6" at New York City; < 3" at Philadelphia; and, < 2" at Washington, DC. There were 5 prior cases that met the above criteria for seasonal snowfall through January 31: 1895-96, 1918-19, 1931-32, 1949-50, and 1972-73. The single case with a colder than normal January (1895-96) saw 43.0" snow in the February-April period in New York City. All of the remaining four cases, all of which had a warmer than normal January, had less than 12.0" (mean: 4.6"; median 2.8"). Should blocking largely fail to develop in February, the risk of the very low snowfall for the remainder of winter 2019-20 would increase.

The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was +0.3°C for the week centered around January 22. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.10°C and the ENSO Region 3.4 anomaly has averaged +0.48°C. The remainder of winter 2019-2020 will likely feature neutral-warm to weak El Niño conditions.

For February 1981-2019, the following monthly temperature averages were recorded for cases when the ENSO Region 3.4 anomaly averaged 0.00°C to +0.75°C:

ENSO R1+2 Anomaly < 0: AO+: NYC: 36.9°; Philadelphia: 37.6° (n=101 dates); EPO+ subset: NYC: 40.5°; Philadelphia: 40.8° (n=57 dates)
ENSO R1+2 Anomaly < 0: AO-: NYC: 34.7°; Philadelphia: 34.9° (n=97 dates)

ENSO R1+2 Anomaly > 0: AO+: NYC: 35.7°; Philadelphia: 36.6° (n=82 dates); EPO+ subset: NYC: 41.2°; Philadelphia: 42.0° (n=18 dates)
ENSO R1+2 Anomaly > 0: AO-: NYC: 30.9°; Philadelphia: 31.6° (n=58 dates)

February 1981-2019: NYC: 35.8°; Philadelphia: 36.0°

The SOI was +11.78 today.

Today, the preliminary Arctic Oscillation (AO) figure was -0.014.

Upper stratospheric warming will commence near the beginning of February and continue through February 6. Strong Wave 2 activity will occur during the first week of February driving the warming of the upper stratosphere. Overall, most of the stratosphere is forecast to remain cold on the EPS through at least late in the first week of February, but the strong Wave 2 activity has increased the risk of warming that could propagate downward. 

On January 28, the MJO was in Phase 6 at an amplitude of 0.800 (RMM). The January 27-adjusted amplitude was 0.568.

Based on sensitivity analysis applied to the latest guidance, New York City has an implied near 100% probability of a warmer than normal January. The monthly mean temperature could finish near 39.1° in New York City. That would surpass the 38.6° monthly temperature from 1949 to make 2020 the 9th warmest January on record.

The evolution of ENSO in combination with an AO+/EPO+ base state suggests that February will wind up warmer than normal in the northern Mid-Atlantic region. Below normal snowfall is increasingly likely during February.

The last 2 days of January are averaging 35degs., or 3degs. AN.

Month to date is  +7.0[39.4].        January should end at  +6.8[39.2].

The first 15 days of February are averaging {06Z, GFS) 37degs., or about 4degs. AN.       There are about 5 or 6 '50-Degree Days' possible before any turn to 'cold'.       The run does include the mandatory snow----this time about 11" between the 11th---14th period.      The first 50 days of calendar winter will have been wasted by that time.    EURO is a horror, and the CMC has an 1" of snow this weekend before torching.

Will it be 5 50-Degree Days or 5"+ of Snow during the next 15 days?   (start throwing the darts)

28* here at 6am.          27* at 7am.        35* by 11am.      37* by 1pm.      40* by 2:30pm.

Winter to Date     From Dec. 01   +3.8      From Dec. 22    +7.3         Record for Dec. 01(full winter) is +6.4[41.5] compliments of 2001-02.     We are Top Ten material, since 10th. Place is a mere +3.0.

FLASH:   The 12Z GFS has 8 '50-Degree Days' coming up.     Darned if it doesn't reach 60.     Going to bust out and head for an All Time warm February.     First 15 days of February are now averaging 42degs., or 9degs. AN and w/o snow.

A remarkable shift to extreme winter warmth since December 2015. This will be the 11th warmer than average winter month in NYC out of the last 14. Monthly warmest records were set in December 2015 and February 2018. February 2017 was 2nd warmest and January 2017 was 11th warmest. January 2020 is currently 8th warmest on record.

Based on what science or your imagination?

It is too soon to forecast our summer but looking at the southern hemisphere summer, our current positive sea surface anomalies, a new record low arctic sea ice season already being forecast, and how influential the west Atlantic ridge continues to be it would not surprise me if this summer wound up +1 to +3 at the point.

Morning thoughts...

There is strong model consensus that the weekend storm will develop rapidly intensify too far from the region to have an impact on the New York City-Newark area. Little or now snow remains the most likely outcome.

A growing number of variables are suggesting that February will wind up warmer than normal in the Middle Atlantic and southern New England regions. It will be interesting to see if these developments are reflected on the EPS weeklies when they become available this afternoon.

Historic data for years with warmth similar to what is expected during the February 1-7 period have overwhelmingly seen warmer than normal monthly temperatures for February.

Monthly snowfall was typically below normal. The only cases with near normal or greater snowfall were 1991, 2006, and 2008. In the former two cases, the month's largest snowfall coincided with PNA values above +1.250. In the latter case, the PNA was above +0.500.

I bailed when the big pattern collapsed on the models around 1/15

Getting a foot of snow the first two days of December and having snow cover pretty much solid until around the 20th (in the HV I know others didn't even get that) started this winter out with such high hopes. It's been nothing short of a disaster since Dec 22nd. Bluewave posted this earlier and if memory serves this is now the 4th warmest Dec 22 through January 29 period in history. It doesn't get much worse than that.

WTS and with no prospects of a pattern change in the foreseeable future I for one am taking a break and will revisit and hope for  some changes by the middle of the month.

One note of hope, and I have posted this several times in the last couple of weeks, March has been the snowiest month in NYC in 4 of the past 5 seasons. Odder still March has been colder than February in two of the last three seasons. Don't be shocked if we repeat the same thing again this year. I'll take snow in any month, but I do prefer front loaded to back loaded winters, but again this year it's just not gonna happen.

Figures that we would get such an extreme Arctic reversal pattern going into January. Last year featured new records for positive 500 mb height anomalies over Alaska and a small region north of Greenland. This January had one of the strongest +EPO/ +AO combinations that we have seen this time of year.

One thing I have learned over the past few years: Broadly speaking, Pacific patterns have staying power in this climate regime and LR models often break them down too quickly.

 

In 2013-14 and 2014-15, I distinctly recall models breaking down those glorious -EPO patterns only to see it pushed back over and over again--which of course redounded to our benefit.

 

2018-19 and 2019-20 was the flip side of the same phenomenon and we saw raging +EPO patterns remain robust in spite of LR models constantly forecasting their reversal.

 

In future winters, we should keep this in mind as we try to sift out the head fakes.

Despite a slightly colder than normal to near normal day across the region, what will very likely become the 9th warmest January on record in New York City is now concluding. February will start mild with the first week of the month winding up warmer to perhaps much warmer than normal in the Middle Atlantic and southern New England areas. In a taste of deja vu, the February 1-7 mean temperature could average 40.0° or higher, much as it did during the January 1-7 period.

In addition, little or no snow is likely in New York City, Newark, Philadelphia, and Washington, DC into at least the middle of the first week of February.

Much of the Middle Atlantic and southern New England regions have seen below or much below normal seasonal snowfall to date. Seasonal snowfall totals to date include:

Albany: 35.3" (1.1" above normal)
Baltimore: 1.8" (8.1" below normal)
Boston: 14.6" (7.8" below normal)
Bridgeport: 10.1" (3.1" below normal)
Hartford: 25.3" (4.4" above normal)
Islip: 6.8" (5.6" below normal)
New York City: 4.8" (7.0" below normal)
Newark: 6.9" (6.5" below normal)
Philadelphia: 0.3" (9.6" below normal)
Providence: 11.6" (7.0" below normal)
Washington, DC: 0.6" (7.6" below normal)

Somewhat colder air could return late in the first week of February or just afterward. However, Arctic air is unlikely.

During the coming weekend, a storm moving offshore will likely intensify rapidly as it moves into the waters off New England. However, little or no snow is likely for the New York City area. There remains some possibility that a light accumulation could occur over parts of Cape Cod.

Based on the latest guidance, the likely seasonal snowfall distribution through January 31, will be < 20" at Boston; < 6" at New York City; < 3" at Philadelphia; and, < 2" at Washington, DC. There were 5 prior cases that met the above criteria for seasonal snowfall through January 31: 1895-96, 1918-19, 1931-32, 1949-50, and 1972-73. The single case with a colder than normal January (1895-96) saw 43.0" snow in the February-April period in New York City. All of the remaining four cases, all of which had a warmer than normal January, had less than 12.0" (mean: 4.6"; median 2.8"). Should blocking largely fail to develop in February, the risk of the very low snowfall for the remainder of winter 2019-20 would increase.

The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was +0.3°C for the week centered around January 22. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.10°C and the ENSO Region 3.4 anomaly has averaged +0.48°C. The remainder of winter 2019-2020 will likely feature neutral-warm to weak El Niño conditions.

For February 1981-2019, the following monthly temperature averages were recorded for cases when the ENSO Region 3.4 anomaly averaged 0.00°C to +0.75°C:

ENSO R1+2 Anomaly < 0: AO+: NYC: 36.9°; Philadelphia: 37.6° (n=101 dates); EPO+ subset: NYC: 40.5°; Philadelphia: 40.8° (n=57 dates)
ENSO R1+2 Anomaly < 0: AO-: NYC: 34.7°; Philadelphia: 34.9° (n=97 dates)

ENSO R1+2 Anomaly > 0: AO+: NYC: 35.7°; Philadelphia: 36.6° (n=82 dates); EPO+ subset: NYC: 41.2°; Philadelphia: 42.0° (n=18 dates)
ENSO R1+2 Anomaly > 0: AO-: NYC: 30.9°; Philadelphia: 31.6° (n=58 dates)

February 1981-2019: NYC: 35.8°; Philadelphia: 36.0°

The SOI was +7.78 today.

Today, the preliminary Arctic Oscillation (AO) figure was -0.489.

Upper stratospheric warming will commence near the beginning of February and continue through February 7. Strong Wave 2 activity will occur during the first week of February driving the warming of the upper stratosphere. Overall, most of the stratosphere is forecast to remain cold on the EPS through at least the first week of February.

On January 29, the MJO was in Phase 6 at an amplitude of 1.090 (RMM). The January 28-adjusted amplitude was 0.807.

Based on sensitivity analysis applied to the latest guidance, New York City has an implied near 100% probability of a warmer than normal January. The monthly mean temperature could finish near 39.1° in New York City. That would surpass the 38.6° monthly temperature from 1949 to make 2020 the 9th warmest January on record.

The evolution of ENSO in combination with an AO+/EPO+ base state suggests that February will wind up warmer than normal in the Middle Atlantic region. Below normal snowfall is increasingly likely during February.
