Gusting to 33 mph in Farmingdale. The Ambrose Jet usually peaks between 4-7 pm. So most spots near the shore will see gusts in the 30-40 mph range later on. Some models have peak gust potential over 40 in a few spots further east as we head into the evening. You can see the surf picking up with white caps in Long Beach with a very refreshing breeze for the boardwalk fair. I went to one of those many years ago with no breeze and couldn’t stay more than 15 minutes. So I much more enjoy days like this with a refreshing breeze. https://nysea.com/live-cam/

It comes with the territory of living right near the ocean. Since 2010 to 2013 we haven’t seen that much deep westerly flow with our heat waves. Very strong onshore component to the winds during the warm seasons in recent times. JFK is just weeks away from its longest streak on record of not reaching 100°. But I am not sure if the ASOS was relocated back in the 90s making it more susceptible to sea breezes. So there can be a combination of factors at play here. The part of the airport near Ozone Park is several degrees warmer than where the ASOS is currently located in a marshy area next to Woodmere.

We have been seeing several competing influences in recent months with all the record marine heatwaves ongoing. We knew last summer was probably our best shot at seeing something closer to normal temperature wise with the very strong developing El Niño and record blocking pattern in Canada. This year the expectation was for much more heat as has been the case with El Niño to La Niña transitions in the past. But May broke out of the mold and we didn’t see the more typical low to mid 90s from later in the month into the start of June like in past transition years. This month featured a 598 dam ridge which tied the record from 2018 and 2013. The initial heat earlier in the week went to our north in over the top fashion which has been common in recent years. As the ridge began to weaken the next surge of heat directly crossed our region with 100° record heat. It’s a little different from past years with this over the top warm ups to see such a quick reversal. Now we are seeing more of a trough axis over SE Canada which recently experienced the all-time monthly and seasonal heat in spots. So we are getting several days of cooler weather focused in New England before another warm up. But we are back to an older pattern of heat arriving from the SW as the ridge axis shifts to our sound and west. Models are struggling exactly how far north each succeeding warm surge will get with plenty of convection focused just near or north of the 78 and 80 corridor. The big question going forward is how much heat from the SW makes it into the region as we move into July. Many of the 100° Junes at Newark from the past were also preceded by warmer conditions than we got this late May into June. Some of the 100° Junes were actually the warmest part of the summer. But other years after the 100s in June went into even higher maxes later on. Now we have several competing marine heatwaves for forcing. So the extent of our heat going forward may come down to the placement of the convection riding over the top of the ridge. Where the boundary between major 95°+ heat and more clouds and convection sets up will determine the outcome. Plus we’ll have to see where the dominant Atlantic tropical storm and hurricane tracks set up as the season gets more active over time.

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°

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+

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.
