The Atlantic is definitely starting to take on a -AMO look….wonder if this is the beginning of another long term -AMO cycle. If so, we may be seeing a lot more +NAO in the years to come, a la the 1980’s….

It’s a new hybrid AMO pattern that we have seen since the super El Niño in 15-16. Record SSTs off the East Coast with a cold pool near Greenland. The 1995-2015 +AMO featured warm SSTs across the whole Atlantic Basin. The 1970s to early 1990s -AMO had cold departures across the entire Atlantic Basin.


Current hybrid  AMO with record SSTs off East Coast since 2016

If we can drop below 25° like the models are indicating, then the chances go up for highs staying in the 30s. NYC only made it to 39° last April 2nd. Newark had a record low max of 40° with a record low of 28°. But it’s easier for Newark to set record lows since it isn’t competing with the late 1800s like Central Park.

NYC 

4/2 35 in 1911 36 in 1899 39 in 2021+


EWR

4/2 28 in 2021 28 in 1964 30 in 1954

 

4/2 40 in 2021 43 in 1993 43 in 1965+

do you remember the cold shot in April 1995?

Chris what's causing the cold pool near Greenland, isn't Greenland rapidly warming up?

I tend to agree....the globe has warmed significantly from the end of the last -AMO

Agreed, if we actually do go into a true -AMO along with the -PDO, I wonder if we may see a drop in temps (probably will be very little) or the warming may stop for awhile? But it would be interesting to see what the result is on global temps

Tomorrow will become mostly cloudy. Some showers are likely and temperatures will hold in the 40s across much of the region.

The ongoing generally warmer than normal pattern will likely conclude later during the weekend. Nevertheless, this month could rank among the 15 warmest March cases on record in much of the region.

There is growing potential for the month to end with cooler but not necessarily cold readings. The possibility of a fairly sharp cold shot has increased on the guidance in recent days.

In past cases where the MJO was in Phase 1 during the March 5-15 period with an amplitude of 1.500 or above on one or more days, all four cases when the ENSO Region 3.4 anomaly was positive were warmer to much warmer than normal. In contrast, all three cases where the ENSO Region 3.4 anomaly was negative, as is the case this year, were colder to much colder than normal.

Mean Temperature for ENSO Region 3.4 anomalies < 0°C during March 22-31:

Boston: 38.7°; Normal: 42.2°
New York City: 41.8°; Normal: 46.2°
Philadelphia: 42.2°; Normal: 47.3°

The ENSO Region 1+2 anomaly was 0.0°C and the Region 3.4 anomaly was -0.9°C for the week centered around March 16. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.05°C and the ENSO Region 3.4 anomaly has averaged -0.85°C. La Niña conditions will likely persist through March.

The SOI was +7.37 today.

The preliminary Arctic Oscillation (AO) was -0.366 today.

On March 20 the MJO was in Phase 3 at an amplitude of 2.172 (RMM). The March 19-adjusted amplitude was 2.036 (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 March (1991-2020 normal). March will likely finish with a mean temperature near 46.3° (3.5° above normal).

Well IF Forky is correct then all I can say is that I hope for that glorious 12 hours ( or more ) that Sloatsburg looks like a winter wonderland :snowman:  

You repeat the same thing about Sloatsburg over and over. Please get a new routine

Weird not to see 1967 in this list, 1967 was the benchmark for all backend winters (and bookend winters too).

wow I didn't realize that 4/2018 had the second largest April snowfall at the Park since 1950 since the big blizzard in April 1982.  Should also toss in JFK/LGA totals since some were higher than the NYC totals.

4/1/2006 was 1.5" at JFK

4/9-10/1996 was 4.5" at JFK

4/19/1983 was 1.5" at JFK (latest accumulating snow)

4/7/2003 was 5.5" at JFK

Wow I didn't realize April 1956 had sizeable snow even after that excellent March, very similar to what happened in 2018.
