Newark made it to 100° on Friday and Hillsborough-Duke reached 100° Saturday. Models have a 3rd day approaching 100° today in NJ. The combination of steep gradient, Ambrose Jet, and strong to severe convection pressing in from the west will produce very strong southerly flow this afternoon. All the guidance show widespread 30-40 mph gusts near the South Shore beaches. Some of the higher resolution models like the HRRR and NAM 3km have gusts approaching 50mph at the beaches later. Very rough surf and dangerous rip currents so the lifeguards will probably limit access to the water as the winds pick up.

The HRRR has an interesting set up for Sunday. Highs near 100° in NE NJ with one of the strongest Ambrose Jets that we have seen this time of year. The potential for scattered severe storms could also enhance the wind potential. The model has 40 mph gusts near the Long Island beaches and even some 50mph gusts. It’s very rare to get 50 mph gusts from an Ambrose Jet alone so this may be the interaction with storms pressing in from the west.

The Mesonet sites and COOPs around NYC came in just under the 100° at Newark. Newark…100° Harrison…99° Astoria….97° Corona…98° Fresh Kills….99° Queensbridge….98°

Picked up .86 in 30 minutes. https://www.weather.gov/wrh/timeseries?site=khvn

My heaviest downpour of the month so far with a drop from 92° earlier to 75°.

I think the silver lining is that we haven’t had a legit drought here since 2001-2002 when NYC had actual water restrictions around D3. So chances are this is more of a dry vegetation issue like we have seen in recent years. I know D0 to D2 has resulted in brown lawns periodically. But more often than not, these periods ended with extremes in rainfall which were more impressive than the dry periods which came before them. I guess the big question now is specifically how much heat and dryer conditions will come before any shift to wetter? In any event a string of 90°+ days with 100°days thrown into the mix can really drop the soil moisture near the surface.

98° at the NY micronet station in Corona, Queens and 97° in Astoria. https://www.nysmesonet.org/networks/nyc Corona Temp: 98°F Astoria Temp: 97°F

Most of the guidance focuses the convection next few weeks north of I-78. So maybe scattered convection from time to time around the drier areas of Central NJ. Probably have to be patient for a reversal of this recent dry vegetation stretch.
-
Already up to 90° at the Brownsville micronet in Brooklyn with numerous 89° readings at the surrounding stations.

Yeah, it looks like the warm spots today are in the 98° to 100° range today with the highest temperatures possible on Sunday. Still looking like a very strong Ambrose Jet event on Sunday with 30 to 40 mph gusts at the South Shore beaches.
-
With temperatures already near 80° at 7am, the warm spots in NJ around Newark and Harrison have a shot at their first 100° of season today like the guidance indicates.

The high of 97° at Newark beat the guidance by a few degrees. More westerly flow than forecast verified. So we are back to the old pattern from the past. With increasing heat through Sunday Newark and other warm spots in NJ should get closer 100° with record highs possible especially on Sunday. The record was 98° today and came up one degree short. The expansion of D0 drought conditions into NJ helped out today. Also look at the growth of drought conditions to our SW which will be the source region for the heat. The core of the heat next few days over +20C at 850 mb will go directly through the area instead of over the top like last few days. https://threadex.rcc-acis.org Newark Area, NJPeriod of record: 1931-01-01 through 2024-06-19DateHighest maximum temperatures (degrees F)Top Record 2nd Record 3rd Record 6/20 98 in 2012 97 in 2024 97in 1953 6/21 100 in 1953 99 in 2012 99 in 1949 6/22 101 in 1988 97 in 1943 96 in 2012 6/23 97 in 1965 94 in 1994 93 in 2015+

First 95° of the season for the NYC boroughs at the Corona micronet station. https://www.nysmesonet.org/networks/nyc

Yeah, I observed it for years living in Long Beach from the 70s into 00s. But I never knew it had a specific name until the papers became available online after the internet began. I lived not far from East Broadway and would often have blowing sand down my street as the afternoon progressed. This made it difficult at times getting lunch at the snack shop located on the beach with all the blowing sand. There were always cars parked near the beach that would be covered in sand. https://ams.confex.com/ams/89annual/techprogram/paper_144401.htm

The Ambrose Jet usually peaks from around 4-7 pm.
-
The beaches are going to be packed this weekend. Parts of NJ will get close to 100° with only 70s for the South Shore of Long Island beaches. This will create one of our strongest Ambrose Jet events for late June with gusts to around 40 mph or maybe higher due to the steep temperature differential. So my guess is that the lifeguards may have to really limit access to swimming due to the dangerous rip currents and very rough surf. I can remember days like this growing up in Long Beach when you would get sandblasted walking onto the beach and boardwalk.

I guess we are lucky that our summers since the 15-16 super El Niño haven’t had the kind of warmth we had during the winters. Beating a monthly maximum temperature by 4° like we did in February 2018 when Newark hit 80° during July would equate to 112°. Most people off this forum have been enjoying the lower winter heating demand. But I am not sure how well our grid would handle temperatures above 110°. They would probably have to go into rolling brown out mode in order to keep the grid up.

Yeah, the first two 80° minimums on record for BTV since 2018. Beating the previous record by 2°. That would be the equivalent of LGA having two 88° minimums over this period.

The Euro has had an unrealistic warm bias recently and the GFS has been doing much better. So the GFS now has the potential for 100° heat in NJ on Sunday as the heatwave peaks. We have seen this frequently in recent years with the highest readings starting out to our north like we are seeing now. As the ridge begins to weaken we usually see our warmest temperatures since this allows more of a deep SW flow instead of SSE like recent days. Could also be a very strong Ambrose Jet for the beach goers on Sunday due to the big temperature gradient between NJ and Long Island.

It looks like Upton may have tied the all-time maximum 500mb height record of 598 dam set back in July 2013. But the orientation of the ridge axis this time allowed the warmest readings to go to the north of our area. https://www.spc.noaa.gov/exper/soundingclimov2/ Max Values07/14/2013 (12Z)5980 m06/29/2021 (12Z)5970 m07/05/2018 (12Z)5970 m07/04/2018 (12Z)5970 m07/15/2013 (12Z)5970 m08/28/1977 (12Z)5967 m08/01/1975 (12Z)5964 m

No surprises here as the warmth following the peak of the El Nino is lingering longer than previous events just like the temperature rise last year began earlier.

They just tied their al-time highest June dew point of 74°. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=155&network=ME_ASOS&zstation=CAR&var=max_dwpf&w=all&threshold=100&hour=12&sdate=0101&edate=1231&month=jun&_r=t&dpi=100&_fmt=png
