Heavier showers and thundershowers drenched parts of the region today. Parts of Connecticut experienced flash flooding. Newark set a new daily rainfall record with 1.19" (old record: 1.07", 1952). Mammatus clouds moved across the sky in New York City and nearby regions.

It will be steamy and very warm through the end of the week. Temperatures could reach or exceed 90° in parts of the region.

Afterward, near to somewhat above normal readings will likely prevail through mid-month.

The ENSO Region 1+2 anomaly was +2.9°C and the Region 3.4 anomaly was +0.9°C for the week centered around June 28. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.57°C and the ENSO Region 3.4 anomaly has averaged +0.82°C. El Niño conditions have developed and will likely continue to strengthen through at least the summer.

The SOI was +9.29 today.

The preliminary Arctic Oscillation (AO) was -0.519 today.

On July 2 the MJO was in Phase 2 at an amplitude of 1.687 (RMM). The July 1-adjusted amplitude was 1.614 (RMM).

 

Don, what has kept Long Island so dry the last few days?  The SST are much warmer now (in the 70s).  Yesterday I saw there were big storms passing over Manhattan and today over Coney Island, but they somehow never made it to SW Nassau, how come?

Oceans closed to swimming yet again at Jones beach due to distant lighting from that central Jersey storm. Second time today yet it hasn’t rained for more than a couple minutes of drizzle. Super annoying for someone like myself who understands local meteorology. It’s not going to rain let alone have lighting at the beach today. The powers that be who are going by forecasts are convinced theses thunderstorms are coming. 

The waters are definitely warm enough now so whats causing the storms not to make it east of the city down here?

Probably a combination of the frontal location and stochastic processes. Convection remains challenging to forecast with often large differences among the models and also outcomes.

The next 8 days are averaging    81degs.(73/90) or +4.

Reached 87 here yesterday at 8pm.

Today:  87-91, wind variable, m. sunny, 75 tomorrow AM.

75*(90%RH) here at 7am{was 74 at 5am}some fog/haze.        77* at 9am.      78* at 11am.      79* at Noon.      83* at 2pm.     85* at 3pm.(H.I. 91).     86* at 6pm(H.I. 93).

Another very warm start to the day.

Current temp 79/DP 74/RH 85%

Soupy start this morning 

[SACRUS]

 

79 / 73 here.  Humid and warm the next 3 days with only isolated storms upper 80s, low 90s(heatwave for some). Onshore low a bit but very warm airmass.   

 

7/8 - 7/13 by Fri late a return to a more Florida style pattern with storms chances.  Warm humid with storms through the middle o next week.  Where and when the sun come out it warms quickly but storms could be soakers.  Overall , warm and humid and wet at times.

Way beyond from mid month on - Western Atlantic ride pusling west into the southeast, ridging should refire into TC/OK and expand into the southeast pushing heat towards the region.  Still looks humid and stormy.

Followup to yesterday's lightning strike:

NEW YORK – Two people were injured by a lightning strike near the iconic Nathan’s Hot Dog Eating Contest in Coney Island New York, Tuesday afternoon as strong thunderstorms with frequent lightning swept across the New York City area.

Firefighters and medics were called to the beach at Coney Island after receiving a 911 call of a lightning strike. There, they found two people who suffered injuries from a lightning strike, a New York Fire Department spokesperson told FOX Weather. The two were taken to a Brooklyn hospital, but the extent of their injuries was not given.

High of ~91 here, currently 86/74/94, temp dropped when the marine layer moved in at around 2pm, before then it was fluctuating between 89-91

[JustinRP37]

Hot hot hot out there today. My 4 year old son who loves skiing but warm weather was saying summer is his favorite all winter but now has changed tune and winter is his favorite. Although he does love swimming outside so I guess maybe he will be like me and love winter and summer!

[Rtd208]

High for the day was 96 here.

Current temp 93/DP 68/RH 44%

[psv88]

Hit 94 here. Down to 88 with sea breeze

[SnoSki14]

I'll take desert heat over the sauna any day. 

Just gross outside 

The only positive is that occasionally you'll get good storms

[dmillz25]

Got up to 93 for the high 4th 90 degree day

[doncat]

93° here also and 4th 90°.

[donsutherland1]

Temperatures surged into the 90s across many parts of the region. Highs included: New York City: 93°, Newark: 94°, and Philadelphia: 93°. Another very warm day lies ahead for tomorrow.

It will be steamy and very warm through the end of the week. Temperatures could reach or exceed 90° in parts of the region.

Afterward, near to somewhat above normal readings will likely prevail through mid-month.

The ENSO Region 1+2 anomaly was +2.9°C and the Region 3.4 anomaly was +0.9°C for the week centered around June 28. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.57°C and the ENSO Region 3.4 anomaly has averaged +0.82°C.

Reached a surprising 95. Finally a day with no  clouds from t storms in the area or smoke in the sky probably helps. Down to 85 now.

July 1999 was absolutely amazing and either 1999 or 2002 was the last time we had a super heatwave (my definition = 7+ consecutive 90+ degree highs.)  Tony, if I remember correctly, JFK hit 102 on this day too (or it was the day before or after.)  That was back when we used to have dry heat, not this disgusting soupy mess we have now.

Back then Long Island used to hit 100+ at least every other year too.
