I've seen multiple stations with insane Dewpoint#s, 75-80 while others are 70-75.. at first I thought it was station error but now idk what to believe... could the Dewpoint be that drastically different from shoreline to more or 2 away ?

Vegetation could play a factor

Cheap sensors and evapotranspiration.

I think is this why mine “runs high”. I live right across the street from a forested nature preserve. I can feel temperature differences even just walking a block away sometimes. Especially in the evening. So I don’t think my sensor is wrong, I just think that’s what it is for where my house is located.

HRRR has consistently, since 0z run last night and almost every consecutive run, been showing cells firing over central Long Island during the evening hours tonight. It hasn't been too bad with the location of cells for today, it had the storms over the sound, north shore, CT and SE New England, so who knows if it will be right. Obviously, no model is perfect with convection like this. The front is pretty visible on OKX, still over CT. Storms are still building off of it. Interested to see what happens when it hits the sea breeze boundary.

Cells starting to fire now over Nassau county.

The heatwave that sent temperatures into the upper 90s into southern New England is now concluding. High temperatures today included:

Allentown: 95°
Atlantic City: 98°
Baltimore: 97°
Boston: 98°
Bridgeport: 94°
Concord: 91°
Hartford: 95°
Islip: 94°
Manchester: 94°
New York City-JFK: 93°
New York City-LGA: 98°
New York City-NYC: 97°
Newark: 101°
Philadelphia: 98°
Poughkeepsie: 94°
Providence: 98°
Washington, DC: 97°
Wilmington, DE: 97°

Cooler air will begin to arrive overnight. Even cooler air will move into the region late in the week with the weekend featuring unseasonably cool weather. Outside of the Philadelphia and New York City urban areas, the potential exists for low temperatures to fall into the 50s at some locations.

Across the Atlantic Ocean, parts of the UK, including London, could see another round of withering heat. Temperatures could top out near or above 95° on Thursday and Friday.

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.

In addition, in the 6 past cases when the June AO averaged +0.750 or above (1950-2021), 67% of the following August and September cases featured above normal temperatures. The August ECMWF forecast shows a warmer than normal September in the Northeast.

The ENSO Region 1+2 anomaly was -0.6°C and the Region 3.4 anomaly was -1.0°C for the week centered around August 3. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.05°C and the ENSO Region 3.4 anomaly has averaged -0.68°C. La Niña conditions will likely persist into the fall.

The SOI was -0.67 today.

The preliminary Arctic Oscillation (AO) was +0.675 today.

On August 7 the MJO was in Phase 5 at an amplitude of 1.128 (RMM). The August 6-adjusted amplitude was 1.270 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 61% probability that New York City will have a warmer than normal August (1991-2020 normal). August will likely finish with a mean temperature near 77.3° (1.2° above normal).

I had a cell go over the area with some nice heavy rain, no thunder or lighting. Now a super mugfest out there right now.

Just happy everything got a decent watering as we lucked out last Thursday evening and now with this one.

Wait and see if more widespread for more for everyone later this evening.

New Haven had record high nighttime lows twice in a row… currently 88/78 HI102. The dew point hasn’t dropped below 74 for over 3 days.

It’s the first time that HVN averaged above 80° from July 20th to August 8th.

Maybe with no sea breeze we can get some storms on Long Island.

The seabreeze actually helps to fire storms on LI-it's a boundary that can force warm/moist air to rise as the cool air comes in from the ocean. Unfortunately it screws over the south shore since the boundary usually travels a few miles inland before firing storms, and it's been as dead as anything else for the last couple of weeks.

In the above list, is there any way for you to check the entry that is supposed to end on June 24, 1894 at 3260d because in my data base I do not see any temps above 96 in 1894 and the termination of <99 seems to be July 3, 1898 (100F) which would be 4730 days from the apparently accurate starting date of July 21, 1885 (99F) which generated the 3260d listed. I'm wondering if the program generated an interval from a missing code, otherwise I have faulty data in my data base for 1894.
