even here the sea breeze held off until after 2 PM so we hit 80

I thought it also hit 80 on April 9th?

I enjoyed our 80 here, we were able to hold off the sea breeze until after 2 PM

excellent-- LGA is very similar to JFK-- the top heatwaves are from 1953 and 2002.

Yes, indeed it's about New York City. Here on Long Island we've seen the same thing with the rapid increase in rainfall and wet summers, which blunt the high temperatures but make the lows warmer. JFK is what I use for that data, where it goes back to the 40s and 50s when we had some of our longest heatwaves on record.

New York City mostly-- it's the one which lists the longest heatwaves and when they occurred (I'm chiefly concerned with heatwaves of 7 days and longer.) Of course climate change is making the climate warmer, but the change is nonlinear. It means higher lows but the highest temperatures are not as hot because we are also seeing an increase in water vapor, which makes the air more difficult to heat. The energy of the sun then goes into drying the ground first before it can heat the air.

I'm curious what causes them and why they are only visible just before and just after totality. I heard them compared to sun shining on a swimming pool.

People will likely be moving away from Miami because of sea level rise. They already get sunny day flooding. Projections are that a lot of that coastal population will be moving to Orlando and other points inland.

I find it weird how it didn't affect Miami more than it did. It must have been really small (maybe 5 miles wide?) because Miami is very close to the southern tip of Florida.

it's why our summers don't have the length of heatwaves they used to. Look at the length of heatwaves from the 50s to the 90s vs what passes for heatwave now-- the differences are eyeopening.

The best way I've seen this explained is that air is a fluid like water so a good analogy is a swimming pool full of water. When the sun shines on this pool you can see little shadows shimmering in the water even when there's no wind. These are what shadow bands are like. My question is why do we need a total eclipse to see this effect? Why don't we see it all the time, just like we do in a swimming pool?

This means a hotter summer too, and probably strong westerly flow at our latitude

Because "hot days" are defined by the number of times it hits 90 degrees. How hot a summer is, is tangibly defined that way. I'm done with the humidity driven overnight lows. Higher lows come from humidity, while actual heat determines how many times we hit 90 degrees.

For a short time I think, but 2002 was one of our hottest summers on record, especially here on the south shore. The three hottest summers here were 1983, 2002 and 2010.

That's great, I just had to double down on my benadryl lol. The more it rains the worse my allergies get.

I always think that anyone who complains about heat is overweight. When you weigh 160 pounds heat doesn't bother you. The more you weigh the more you sweat. Time to stop consuming processed food and soda (including diet soda) and all that junk.

Hopefully that ridge doesn't go away after the 20th. In my experience once we hit 85, we usually don't go back to a cool pattern anymore

Sounds like a 1950s type summer

As long as you got at least 100 miles north or east of Syracuse you were in good shape. Watertown only had some high thin cirrus clouds!

That's in August 2027! Also 0% possibility of clouds in the desert! Luxor Egypt will be the place to be with over 6 minutes of totality!

This is the perfect description-- and you know what else it reminds me of (minus the corona of course).... the black lunar eclipse of December 1982. Because El Chichon had just erupted a few months prior, this was the darkest lunar eclipse ever seen. The moon looked like a black hole in the sky, all the larger because the eclipse reached totality two hours before sunrise. It was darker than the surrounding sky and the blackest black I had ever seen. In contrast to the July 1982 total lunar eclipse which was one of the brightest ever seen where the moon was a bright orange color.

Venus on one side and Jupiter on the other side.

That's natural because all life on earth is adjusted to sun as our "white balance" but it's interesting that G type stars like the sun are considered yellow on the H-R diagram. It's also interesting how life on planets that orbit other stars would see different colors-- for life on a planet that orbits a red star for example, that red star would be "white". Any plants on such a planet would be a different color too-- likely purple. On earth, green maximizes the energy available from photosynthesis while on a planet that orbits a red star, purple would be most efficient in converting that sun's light into energy.

Imagine if the moon actually had rings like Saturn does, you'd experience multiple flashes before the real eclipse.
