It doesn’t look like Newark will get another chance to challenge the monthly high of 88°. This is a very rare event for Newark. It will only be the 5 spring since 1950 with both the March and April monthly maximum temperatures occurring before the 15th. Monthly maximum temperatures this time of year usually happen later in the month. Both highs were daily records.

Driving the parkway I’m shocked how barren it is at this point in April. At what point do the trees and flowers normally open up, and have things been delayed this year from the recurrent frosts? Not an area I’m much familiar with. 
 

Even last night my property skirted 32 degrees prior to sunup. None of my flowers have peaked out yet, trees still only basic small buds, and my cherry tree looks rather haggard and displeased.

Tomorrow will be unseasonably warm before somewhat cooler air returns for the start of the weekend. Sunday could see one more spike in the temperatures as the development of a new round of blocking leads to a more sustained cool pattern that could last into the beginning of May.

During the 1991-2020 period, the April 25-May 5 period saw temperatures average 1°-2° below normal when strong blocking coincided with Niña conditions. Afterward, approximately 50% of such cases went on to see a warmer to much warmer than normal second half of May.

The ENSO Region 1+2 anomaly was -1.7°C and the Region 3.4 anomaly was -0.9°C for the week centered around April 13. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.80°C and the ENSO Region 3.4 anomaly has averaged -0.88°C. La Niña conditions will likely persist into the start of June.

The ENSO Region 1+2 anomaly of -1.7°C is the lowest such figure on record for a week centered around April 13. The old record was -1.4°C, which was set in 1994. Since 1982, there were five prior cases where the ENSO Region 1+2 anomaly was -1.5°C or colder. 40% of those cases saw La Niña conditions the following winter; 40% saw neutral-cool ENSO conditions that approached but did not reach La Niña status. 20% of those cases saw an El Niño develop during the following winter. More immediately, the magnitude of cool anomalies implies that the proverbial stage is set for an active to very active Atlantic hurricane season.

The SOI was +25.81 today.

The preliminary Arctic Oscillation (AO) was -1.495 today.

On April 19 the MJO was in Phase 1 at an amplitude of 1.370 (RMM). The April 18-adjusted amplitude was 1.307 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 75% probability that New York City will have a cooler than normal April (1991-2020 normal). April will likely finish with a mean temperature near 53.0° (0.7° below normal).

Morning thoughts…

It will be partly sunny, breezy, and warm. High temperatures will likely reach the middle and upper 60s in much of the region. A few locations could reach or exceed 70°. Likely high temperatures around the region include:

New York City (Central Park): 66°

Newark: 67°

Philadelphia: 70°

Tomorrow will be somewhat cooler.

Normals:

New York City: 30-Year: 64.5°; 15-Year: 64.9°

Newark: 30-Year: 65.3°; 15-Year: 65.7°

Philadelphia: 30-Year: 67.3°; 15-Year: 67.7°

wow really early in 2000, before the 10th in both months!  It didn't even hit 80 prior to May?  Must have been one of the latest first occurrences of that!

Yeah that trough over the Maritimes needs to be gone. Pronto. We’re likely below average until then. 

I have to say I'm loving this weather, as long as there is lots of sun I dont care what the temperatures are.  One other very positive thing, I dont know what that big storm did, but ever since then my allergies have completely vanished!  As in completely gonzo!  I haven't even thought about them in a week!

The storm probably washed away the pollen/allergens. Agree, hopefully that continues at least.

The warm spots may be able to sneak in a 70° today before we get backdoored for the weekend.

20 days early?  I don’t think so

May be some color interpretation differences ... but I don't see many pixels on that chart at that far end of the spectrum.   Looks rather mid way ... so 10 give or take? 

Otherwise, even so yeah .. .not sure how the source - from the USGS if that should matter to anyone - goes about tabulating the data or enough so that an algorithm would paint such a dense, noisy presentation - it's also now 5 days ago since that chart date, but that was as of April 17.

Looks good in NJ. 60s and dry almost every day. 

Yeah mostly nice weather with 60s here, but the cool shot mid-late next week does look pretty impressive. We could have a couple days (probably wed and thur) where high temps stay in the 50s, and some frost at night not too far northwest of our area.

Next week looks awful. I truly hate spring up here. we need to be done with the 50s

Yeah it's starting to get on my nerves a lil too, especially after that teaser of a nice day we had last Thursday.  The higher spring sun makes some positive difference even on cooler days, but come on!
