In summary, the two weather sites are reporting different conditions. The weather site in College Park, Maryland is reporting that it is 99F. The weather site in New York City is reporting that it is a tornado that caused extensive damage.

Its 101F and 37% humidity.

Stupid global warming.

And it feels like its 110 outside thanks to the humidity. (Also, the sun is going down now)

It's the Dog Days of summer.
The term "Dog Days" was coined by the ancient Romans, who called these days caniculares dies (days of the dogs) after Sirius (the "Dog Star"), the brightest star in the heavens besides the Sun.

Popularly believed to be an evil time "when the seas boiled, wine turned sour, dogs grew mad, and all creatures became languid, causing to man burning fevers, hysterics, and phrensies" (from Brady’s Clavis Calendarium, 1813).

The Dog Days originally were the days when Sirius, the Dog Star, rose just before or at the same time as sunrise, which is no longer true owing to precession of the equinoxes. The ancients sacrificed a brown dog at the beginning of the Dog Days to appease the rage of Sirius, believing that that star was the cause of the hot, sultry weather.

It's only 81 here, but at 83% RH you wouldn't want to exert yourself outdoors. The air feels thick.

Currently, it's only 78...and 85% humidity! It was hotter mid-afternoon, of course. I'm hoping some of the thunderstorms that have just rolled through are bringing a more pleasant change of temperature, but the ones we got every other day this week only seem to be bringing worse and worse heat and humidity.

We got a line of them last week that led to the formation of either a tornado or a VERY strong microburst that snapped hundreds of huge trees on the shore a pond a couple of miles from here, smashing camps, lake-side homes, vehicles, etc. Trees with trunks 2-3' in diameter were snapped like twigs, and those that would not snap were uprooted. Power may be restored there in a week or so - restoration of damaged buildings and clean-up of debris will take months, at best.

Parts of my garden were flattened by the storms, although I have shored up the pepper plants, re-braced the tomato plants, re-trellised my squash and cucumbers, and it looks like most everything will recover. Some of the "convenience" plantings like a windowbox of cucumbers on the rail of the back deck are a loss. Cucumber plants can stand some stress, but a 15' fall off a railing to the ground is pushing the envelope.

It was a little above 90F here today, and really humid. I was helping paint my grandfather's house today, and the house has no air conditioning!

Only 37% ? I thought you east coasters (that is a little different from a coffee coaster) didn't even recognize humidity until it hit %110?

Yeah, 37% is low for around here (Usually in the +80% range), but at such high temperatures even low amounts of humidity becomes horrible.

It will get stickier and stickier. Everybody's guilty.

3 nights ago there was this big storm and it rained all evening and all night - first very hard, then some of the drops fell frozen and finally there was a thuinderstorm - all rain and lightning and thunder and A few times I went up to the window and imagined that I was in a horror movie and a mad scientist upstairs was making his monster. :approve: :smile:

Tornado Struck New York City
Aug. 9 (Bloomberg) -- Meteorologists confirmed that yesterday's storms in the New York area included a tornado that cut a 9-mile path through Staten Island and Brooklyn.

The twister, estimated to have winds of between 111-135 miles (179-217 kilometers) an hour, damaged the roofs of 11 homes in the Bay Ridge area of Brooklyn, and later tore off the roof of a car dealership at the corner of 66th Street and Fifth Avenue, the U.S. Weather Service said in a report on its Web site.

The tornado, which touched down in Staten Island at about 6:22 a.m. local time, caused extensive damage to trees, the service said. The tornado was a Category 2 on the 0-5 classification scale used by the weather service, in which 5 is the most powerful. [continued]

Here in Oregon it is a sweltering 75 degrees, which is actually too hot for me. :biggrin:

I remember tornadoes in Vermont when I lived in upstate NY, I was surprised that they had tornadoes in the north east.

New York ranks 30th in the number of tornadoes and 27th in the number of deaths.

I was once in a tornado in Long Beach, Ca. We didn't realized what was happening until we heard the choo choo effect. Luckily it wasn't large enough to do serious damage to the building.

Had a close call in Frankfurt, Indiana. A large tornado passed right by my hotel in the middle of the night. I awoke to the "take cover" warning on the TV! That was a bit exciting. :bugeye: I was in a Holiday Inn located right in the middle of about 600 sq miles of corn fields.

Yeah, that happened to me near Saratoga Springs, NY, we were having a terrible storm and then I heard that train noise and thought I was a gonner.

I also found out that there is a fault line here in Missouri and we are way overdue for a catastrophic earthquake. :bugeye:

Whoops! You have a point there. In fact I would bet that the quake will generate Earth lights that trigger a lightning strike that hits your chainsaw while your are standing under a dangerous tree... :biggrin:

Everyone be on the lookout for dangerous trees. They are easy to recognise, they have long limbs and a green coat.

Evo has a chain saw??
 

FAQ: Is Global Warming to Blame for This Heatwave?

Is global warming causing this heatwave?

While it is difficult to attribute a single weather event to global warming, the increasing trend of heatwaves around the world is a strong indication of its role. Climate scientists have found that the Earth's average temperature has been steadily rising due to human activities, such as burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere. These gases trap heat and contribute to the overall warming of the planet, making heatwaves more frequent and intense.

How do scientists study the link between global warming and heatwaves?

Scientists use a variety of methods to study the connection between global warming and heatwaves. This includes analyzing long-term temperature data, running climate models to simulate different scenarios, and conducting experiments to measure the impact of greenhouse gases on temperature. While each method has its limitations, when combined, they provide a strong body of evidence that supports the link between global warming and heatwaves.

Are heatwaves becoming more common due to global warming?

Yes, heatwaves are becoming more frequent and severe due to global warming. According to the National Oceanic and Atmospheric Administration (NOAA), the number of heatwaves in the United States has increased significantly in the past few decades. Moreover, a study published in the journal Nature Climate Change found that the probability of extreme heat events has increased by at least 50% in nearly half of the world's land areas.

Can we prevent future heatwaves by reducing greenhouse gas emissions?

While we cannot completely prevent heatwaves, reducing greenhouse gas emissions can help mitigate their intensity and frequency. By decreasing our reliance on fossil fuels and transitioning to renewable energy sources, we can reduce the amount of heat-trapping gases in the atmosphere. This, in turn, can slow down the rate of global warming and potentially lessen the severity of future heatwaves.

What are the potential consequences of more frequent and intense heatwaves?

Heatwaves can have a range of consequences, including negative impacts on human health, agriculture, and the economy. They can lead to heat-related illnesses, such as heatstroke and dehydration, as well as exacerbate air pollution and allergies. Heatwaves can also cause crop failures and damage infrastructure, resulting in significant economic losses. Moreover, they can disproportionately affect vulnerable populations, such as the elderly and low-income communities, who may not have access to air conditioning or other resources to cope with extreme heat.
