A hot day that saw temperatures rise into the middle and upper 90s in much of the region has concluded. Tomorrow has the potential to be a few degrees warmer. Tomorrow will feature sunshine with near record and record heat. Highs will reach 95°-100° with higher figures in the lower 100s across much of the region.

Select daily records for July 24:

Allentown: 95°, 1999 and 2016
Baltimore: 101°, 2010
Bridgeport: 95°, 2010
Hartford: 96°, 1987
Islip: 96°, 2010
New York City-JFK: 97°, 2010
New York City-LGA: 98°, 1999 and 2010
New York City-NYC: 97°, 1999 and 2010
Newark: 99°, 2010
Philadelphia: 98°, 2011
Poughkeepsie: 100°, 1933
Washington, DC: 101°, 2010
White Plains: 95°, 1952

Monday will be slightly cooler, but temperatures will still reach the lower 90s across much of the region. Afterward, temperatures will become several degrees cooler through midweek.

During June 16-20, the MJO has been in Phase 1 at an amplitude of 1.500 or above. Of the six cases that saw such an outcome during June 15-25 (1988, 2003, 2010, 2012, 2017 and 2020), four had a warmer than normal July, one was somewhat cooler than normal and one was cooler than normal. The latest guidance all indicates that July will wind up solidly among the warmer than normal cases.

The ECMWF seasonal forecast indicates that the summer will be warmer than normal throughout the region and across much of North America. Based on how the pattern has been evolving during the spring transition to summer, it is more likely than not that the warmest anomalies of the summer will likely occur in July and August with June being the coolest of the three months in the Northeast. The latest ECMWF monthly forecast indicates that July will be warmer than June relative to normal and that August will be the warmest summer month relative to normal.

In addition, in the 6 past cases when the June AO averaged +0.750 or above (1950-2021), 50% of the following July cases were warmer than normal. 67% of the following August and September cases featured above normal temperatures.

The ENSO Region 1+2 anomaly was -1.2°C and the Region 3.4 anomaly was -0.6°C for the week centered around July 13. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.40°C and the ENSO Region 3.4 anomaly has averaged -0.60°C. La Niña conditions will likely persist through the summer.

The SOI was +1.66.

The preliminary Arctic Oscillation (AO) was -1.122 today.

On July 21 the MJO was in Phase 8 at an amplitude of 1.148 (RMM). The July 20-adjusted amplitude was 0.689 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 97% probability that New York City will have a warmer than normal July (1991-2020 normal). July will likely finish with a mean temperature near 80.0° (2.5° above normal).

That 84.4 looks like an error to me in the saved file on the website. I don’t remember seeing that buoy go warmer than 79° to 81°. It would be helpful if there was a saved regional weather round up for that day out of OKX with the actual buoy reports. 

It does look too high of a number to be true and it's most likely wrong. I'll be honest, I don't particularly recall the water being that warm either, highest being about 81°. 84° would not be an accurate measurement of the average temperature in the top 5ft of the water column. Checking the data, the air temperature was cooler than the water on that day.

Newark is tied with 2011 for the warmest July. It’s the 3rd warmest July in Somerset County NJ. Philly is in 4th place for warmest July. The heat also extends into our northern suburbs. Danbury is currently having their 2nd warmest July.

Today looks like the peak of the heatwave with Newark making a run on a record breaking 102°. It will also be the first time that Newark had a 5 day 100° heatwave. The best that Newark did  in the past was 4 consecutive 100° days.

I feel like that depiction out towards riverhead is incorrect,  they had 2-3 inches of rain in the past week. 

You aren’t going to get that kind of IMBY resolution from a satellite map. But most of Suffolk south of the LIE has had very little rain this month. The sea breeze front has been stalling along the North Shore.

88/62 off a low of 70.  Only clouds would limit area wide near or record highs today and tomorrow.  95 - 100 in the area with the hotter/ dryer spots hitting low 100s.  Front approaches tomorrow with storms and clouds ahead of the main passage and depending on clouds from those advanced storms will determine if we get more stron heat on Monday (7/25).  Tue (7/26) depending on how much rain / storms linger if the 90s plus heatwave streak is broken for the majority of the area.  

 

Wed (7/27) The W. Atlantic Ridge begins to expand west for what looks like a period into and beyond the end of the month.  Initially its a Bermuda high type pattern through the end of the work week Fri (7/29) and into next weekend, more humid , warm and continued storm chances (much increased).  At times it looks like the W .A.R will connect with the WC/ROckies ridge and pushe stronger heat into the area.  The next shot at some stronger heat would be Thu (7/28) and Fri (7/29) and then the middle of the  next week.  Overall warm to hot pattern but should see much increased storm chances.

Right, just seemed odd seeing that blob on the north shore. I'm assuming as well that's a blooper of sorts.  

 

Especially since riverhead, where it shows drought has seen nearly 4 inches of rain this month already lol
