There are a few types of plants that are looking weak due to disrupted development from that freeze. Some don't really show it but, because they started flowering and the flowers froze they won't be fruiting and seed production will be severely reduced. 

My Wisteria browned out, my hostas look like they were scorched. Worst freeze in 20 years for tree fruits and the wine industry from VA through the northeast.

We need one or two loaded up El Niño southern jet setups to make it this far north with cold air. We don’t want too much blocking to squash everything south. 

Agree but I doubt that would happen with a strong el nino unless a big block forms.

55 / 39 pretty much basically a repeat of Thursday today.  Cloudy showers/ cooler Saturday. Warmer Mothers Day but clouds could cling on.  Overall cooler and wetter weerk 5/9 - 5/16.  Moderation towards the 17th and perhaps more persistent warmth in the 5/24 period / beyond.

Anyone else notice that the freeze a couple weeks back after 90 degree temps ended up damaging and killing some oak and japanese maple leaves that were leafing out
 
Brown and shriveled. Doesnt happen often. Just a cae of bad tining Google says they will releaf but with smaller leaves

No freeze here in Nassua. My early girl tomatoes which have been in since early April are taking off now.
One thing we do have is damage to broad leaf evergreens from the winter. Especially skip laurel and Japanese acuba. My red rocket crape mryrle which died back to the ground in 15 made it this year though and is finally starting to leaf out.

Mother's day is trending wetter. Got tickets to Grounds for Sculpture down in Hamilton, crossing my fingers.

Only thing that truly got damaged was my citronella I had just transplanted.  Most of it browned but is coming back nicely.  My catnip looked bad too but rebounded. 

 

Hostas curled up but nothing died thankfully.  Any veggies we had in pots outside were dead on night two.

Yes, I noticed lots of damage to many plants around my property and when taking the dogs for a walk around the neighborhood.  My one Magnolia (about 25' tall) took the biggest hit.

Looking around this area there’s lots of tree damage I assume from the winter storms.

A strong or super Nino ensures there’s lots of mild Pacific air flooding in. But it will also be moist and we won’t have the endless cutters/SWFE we sometimes see in Nina’s. It’ll be southern stream driven and we have to hope to time one or two of them with cold enough air. We all know what happened in Nino seasons like 2002-03, 2009-10, 1982-83, 2015-16 etc. If only 2/6/10 could’ve edged north a little more. 

[Stormlover74]

Of course now the models do bring in some rain sunday afternoon

Wasn't 2002-03 not nearly as strong a Nino as those others though?

Somewhat cooler weather will continue through the remainder of the week. The first 10 days of May will likely see temperatures average cooler than normal normal overall.

Showers are possible tomorrow into tomorrow evening as a warm front moves across the region. Sunday will turn warmer with highs reaching the 70s.  Additional rain and somewhat cooler conditions will return for Sunday night into Monday. Rainfall amounts are not likely to be significant.

In the long-range, there has been a shift in the guidance toward a near or somewhat warmer than normal second half of May. The probability of a warmer than normal second half of May has increased.

The ENSO Region 1+2 anomaly was +1.3°C and the Region 3.4 anomaly was +0.9°C for the week centered around April 29. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.47°C and the ENSO Region 3.4 anomaly has averaged +0.42°C. El Niño conditions will likely develop during late spring or early summer.

The SOI was -0.90 today. 

The preliminary Arctic Oscillation (AO) was -0.612 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 60% probability that New York City will have a cooler than normal May (1991-2020 normal). May will likely finish with a mean temperature near 62.2° (1.0° below normal). 

Supplemental Information: The projected mean would be 0.2° below the 1981-2010 normal monthly value.

The STJ should be active. Thats step 1. Step 2 would be blocking. Step 3 would be a negative EPO/ AO.

2009-10 is a perfect example that proves that a strong el nino winter can be cold and snowy.

2009-2010 was a much weaker modoki compared to the 2023-2024 full basin event and what 2026-2027 is projected to be.

Plus it occurred back in a much colder climate prior to the baseline temperature jumps in 2015-2016 and 2023-2024.

This is why places from DC to Philly haven’t experienced anything close to those snowfall totals since. 

[nycwinter]

rain coming in a little sooner then expected this morning..

[SACRUS]

58 / 48 clouds and scattered showers.  The first of what will be 4 or 5 of the next 7 days cooler/ cloudy and some lighter rain . showers today with some nicer or partial niver days mixed in Sunday - Tuesday as trough and sort of a cut off ULL move through this week.  By next weekend we should moderate towards and above normal with next show at some more persistent warmth >80 5/17 - 5/24 and beyond.

1988 - A massive cyclone in the central U.S. produced severe thunderstorms from eastern Texas to the Upper Ohio Valley. A strong (F-3) tornado ripped through Middleboro KY causing more than 22 million dollars damage. Thunderstorms in east central Texas produced hail three and a half inches in diameter at Groesbeck, and near Fairfield. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms developing ahead of a cold front in the south central U.S. produced golf ball size hail and wind gusts to 62 mph at Mira LA, and during the morning hours drenched Stuttgart AR with five inches of rain. (The National Weather Summary) (Storm Data)

I expect another baseline temperature jump this year. The amount of heat release in the pacific is going to be astronomical. The cpac hurricane and Epac typhoon seasons should be historic.

Just had a Facebook video reminder for May 9th,2020 and the snow flakes we got in little ferry.  Was also amazed at how far behind all the tree growth was compared to this spring. 

 

Ohhh and it's raining in Bradley Beach. Cold as hell too.
