It will be interesting to see if the La Niña continues to get stronger in April. The blocking pattern to end March and start April matches the La Niña composites. It’s one of the few times of the year when a La Niña can be colder than average here. So we’ll get near record Arctic cold here early next week. While the Arctic air quickly moderates to start April, the EPS still has a trough near the Northeast. The La Niña composite for April has a cooler Northeast trough. So we’ll have to wait and see if the EPS continues the cooler than a average temperature beyond the start of April. 

Near record Arctic cold early next week

Top 10 warmest March through the 25th fits the warming background pattern and La Niña.

April La Niña composite is cooler….How long will the pattern last?

The projected Niña strengthening being forecasted by the models looks credible given the atmospheric and oceanic states. It’s starting to look it a very real possibility that we see a La Niña for the 3rd winter in a row

we've also had some incredibly cold weather during la ninas- winters of 1915-16 and 2010-11 come to mind, but they usually come after el ninos.

it's not putting a dent in global temps, which are still going up.

I'm jealous of the lake region

More snow for them on the way 

They've mostly had a lousy to awful snow season. Syracuse has about half its yearly average. Buffalo is about average, Rochester is below average. Not that unusual for them to still be getting snow in late March.

So far I’m liking our chances for tropical activity later this year.

The ongoing generally warmer than normal pattern will likely conclude during the weekend.

A fairly sharp but short-lived cold shot is likely as a very cold air mass overspreads the region on Sunday. The arrival of the cold air could produce snow flurries and perhaps snow showers in parts of the region. Monday and Tuesday could see low temperatures fall into the 20s in New York City and Philadelphia.

The mean last dates for readings below 30° are:

New York City: March 22 (1981-10: March 24)
Philadelphia: March 22 (1981-10: March 25)

Last year, both cities saw the temperature fall into the 20s for their last time on April 2.

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, as occurred this year, 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°

Actual data coupled with modeling for the rest of March show that all three cities will wind up with a colder than normal March 22-31 period.

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 -1.72 today.

The preliminary Arctic Oscillation (AO) was -0.635 today.

On March 23 the MJO was in Phase 4 at an amplitude of 1.219 (RMM). The March 22-adjusted amplitude was 1.321 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 99% probability that New York City will have a warmer than normal March (1991-2020 normal). March will likely finish with a mean temperature near 45.7° (2.9° above normal).

its good to see that the number of snowy winters is much higher than the number of cold ones.  if you go by snowy winters (30"+ seasonal snowfall, you get 7 snowy vs 6 nonsnowy.)

teens in April in 1982 wow

did NYC get into the teens too?

I dont see why not, since Newark got down to 16 and 17.

23 on 4/5/1995 is pretty cold too, I remember that dry cold shot well.

Too early to tell. If we do though, if the polar vortex doesn’t end up stronger than normal the winter should be better. The past couple of la ninas have done a good job cooling off the ocean, leading to a weaker pacific jet. La Niña with blocking is very good.

Small hail or graupel possible today with some of the steepest lapse rates we have ever seen here from the surface to 500 mb. Very unusual looking soundings for this part of the country. Could also be some thunder with the stronger cells. Then snow squalls possible with the Arctic front later tomorrow.

Morning thoughts…

It will be variably cloudy with near seasonable temperatures. High temperatures will likely reach the lower and middle 50s in much of the region. Likely high temperatures around the region include:

New York City (Central Park): 53°

Newark: 54°

Philadelphia: 55°

Noticeably colder air will arrive tomorrow.

Normals:

New York City: 30-Year: 53.3°; 15-Year: 53.9°

Newark: 30-Year: 54.2°; 15-Year: 55.1°

Philadelphia: 30-Year: 56.4°; 15-Year: 57.1°

The last 6 days of March are averaging  39degs.(33/45) or -7.

Month to date is  46.7[+4.8].         March should end at  45.2[+2.6].

Reached 48 here yesterday.

Today:   50-54, wind w. and breezy, cloudy, drizzle.

Some off and on snow in the air from late Sunday PM to Monday PM on the EURO.      Here is the strongest 1hr. period.

1648490400-C5IykNPomPA.png

48*(60%RH) here at 7am.         51* at Noon.       53* at 1pm.      54* at 2pm.  Single loud thunder at 2:06pm-not raining or hailing.       55* at 3pm.         45* at 11am.
