Today and Tuesday: Be careful in the heat of the afternoon. Heat indices could be around 90 degrees or better.
It looks like high pressure will be strong enough today and tomorrow to offer us nothing but sunshine. I had an isolated shower or storm chance on there, but this atmosphere is so stable that I can’t imagine anything being able to develop in this airmass. That means temps will be able to climb into at least the mid 80s. Humidity will be increasing, too, so be careful if you have to be out in the heat this afternoon or Tuesday afternoon.
By Wednesday, the atmosphere becomes more conducive for a shower or storm, especially in the afternoon/evening. Those chances will remain isolated, however. A slow-moving cold front creeps closer on Thursday and Friday and that will take our rain and storm chances to at least 50%. That means about half of us should see some rain. I wouldn’t be surprised to see those rain chances rise.
At this time, no widespread severe weather is anticipated with this system.
The unsettled weather may continue right on into the weekend, with more mainly afternoon/evening storm chances sticking around.
Not much to add here at this time.
Things remain quiet in the tropics. We have a disturbance that is being monitored wayyyy out in the Atlantic again. It has a 20% of developing. Regardless, this system poses absolutely no threat to land.
Today’s weather record has a place in black history. If you study history any at all, you’ll find the weather having rather large impacts on history quite frequently.
On this day in 1831 the sun turned blue. Or green. Or milky white. It depends on where you were. In the South it was blue, but New Yorkers claimed the sun was a greenish hue. You could even see black spots on the sun. This lasted the better part of the day, beginning around noon at most places and persisting until sunset.
As far as a cause goes, the color changes were the result of dust and smoke in the air. The summer of 1831 was a dry one and there several wildfires across Virginia and surrounding states. Furthermore, Mt. St. Helens was active at this time too and the ash/smoke from that volcano may have been having an effect on the sun in the eastern U.S. We see “blue” suns from time to time with volcanoes, so it’s certainly a phenomena that isn’t completely unheard of.
But, this was 1831 and many folks knew little about the atmosphere, and even fewer knew of a volcano on the West Coast, so many jumped to a divine cause for the discolored sun. One such person was a fiery preacher named Nat Turner. He knew the blue sun was God telling him it was time for a slave uprising. He and fellow slaves murdered their owner and gathered up others to fight for their cause.
And fight they did.
This became the largest, most effective and sustained slave uprising pre-dating the Civil War. The uprising was inspired by today’s blue sun but the uprising didn’t occur until the 21st. They realized it would take planning. Never the less, the blue sun that shone over Georgia on this day was just the kind of sign Turner had been looking for. This was the diving calling for an uprising. He knew he would be the “Moses” of his day.
The uprising spread fear throughout the South and let to nationwide concerns of war. As we all know, those fears would come to fruition about 30 years later.
In the end, about 75 slaves participated in the rebellion that resulted in the murder of 51 whites. After many weeks of rebellion, things went sour and Turner ended up being captured in a swamp. He was executed, along with 56 black slaves who were captured with him. An additional 200 slaves were killed, either trying to join the rebellion, or being accused of wanting to join the rebellion.
The fear that this rebellion brought to slave owners never ceased, and many argue that this was the beginning of a change that would be a part of a war that would cost us more American lives than any other war in U.S. history.
The rebellion also resulted in strict, new legislation throughout the South that prohibited the education, movement, and assembly of slaves. The legislation also stiffened pro-slavery convictions that persisted until the American Civil War (1861–65).
And it all started because smoke turned the sun blue.
The Perseid meteor shower will still be going on tonight. After about an hour or so of skywatching, I ended up counting 15 meteors last night. Some of them were very impressive! So, go out and look up tonight.
