Chance of storms and watching the tropics again

Forecast_Template

Weather Headlines

–Scattered showers and storms for today and tomorrow

–Hot & humid, with isolated (mainly afternoon) storms expected through the yard sales.

–Another weak system arrives Sunday with slightly better rain chances

–Watching the tropics (see Tropics section below)

Main threats

TODAY & WEDNESDAY: Any storm that develops could become strong, with heavy rainfall, frequent lightning, and gusty winds.

Summary

We’ll see a weak frontal boundary move our way today. With so much heat and humidity around, this front could be just enough to set off some showers and storms for some of us. Not all of us will see rain, but the ones who do could see some heavy downpours and frequent lightning.

On Wednesday, the front sags across our area and tries to push south. Once again, this will likely set off some scattered showers and storms.

The boundary pushes just south of us for the rest of the forecast period. There will be enough heat and humidity to leave a chance for an afternoon shower or storm. It just wouldn’t be a summer yard sale forecast without a chance for a storm, right?

Our next weak frontal system may try to push in for Sunday, leading to a bit of an uptick in rain chances.

Tropics (time to bring back this section!)

The tropics are looking a bit more active today! The threats aren’t all that great at this time, but this is certainly the time of year when we have to keep an eye on everything.

As of this morning, there are two threat areas to monitor over the next five days. I should reiterate that there are no immediate threats to the US. Anyone with cruises planned over the next week or two should keep an eye on this, however, as well as anyone with beach plans to the Southeast coast.

Since this is Shark Week on the Discovery Channel, I thought I’d share some weather and shark facts.

Sharks have been observed moving to deeper waters when a tropical storm approaches. The deeper waters would protect the sharks from rough waves, etc. that would be found in shallow waters.

In 2001, young Blacktip sharks at Mote Marine Laboratory fled the shark nursery and went to deeper waters just hours before a tropical storm arrived. As soon as the storm had passed, the Blacktips came back to the nursery. That was the only time the sharks ever left the nursery. The sharks likely sensing a drop in barometric pressure, which signaled them to seek safer waters.

Records

It had been nearly ten years since the city of Nashville had recorded a high temperature that was higher than 100 degrees. On this day in 1999 that changed when the city hit 101 degrees.

A 40-minute hailstorm hit the town of Fort Collins, Colorado on this day in 1979. Softball and baseball-sized hail pummeled automobiles and homes. Twenty-five people were injured, mainly from hits to the head by hailstones.

One year ago today

The high temperature was 83 degrees, after a morning low of 62. Only a small bit of rain was recorded (0.02″).

News

History was made in the United Kingdom last week, but it’s not exactly something Brits are excited about. The city of Cambridge recorded a high temperature of 101.7 degrees last Thursday. That is the highest temperature ever officially recorded in the United Kingdom, since records began.

To make matters worse, most people don’t have air conditioning there because it’s not something you need enough to have.

Earlier this summer, Anchorage, Alaska recorded their hottest temperature on record when that city hit 90 degrees on July 4th.

You all have a great day!

A chance for the gardens to get some water

Forecast_Template1

Weather Headlines

–Tuesday and Wednesday will offer the best chances for showers and storms

–The Yard Sale forecast is looking very summer-like

Main threats

While no widespread hazardous weather is expected, any storm that develops Tuesday or Wednesday could become strong to briefly severe, with damaging winds, frequent lightning, and heavy downpours beings the main threats.

Summary

For today, we’ll see hot and humid conditions, along with a slight chance for an afternoon/evening shower or storm.

By tonight, a weak cold front will be approaching and that will provide a chance for showers and storms in the overnight hours. That rain chance continues into Wednesday, as that front just sags very slowly through our area. “Cold” fronts this time of year just don’t have a lot of spunk left in them by the time they reach us.

Once this system clears out Wednesday evening, we’ll just see hot and humid conditions through the weekend. Yard Salers should pack plenty of water and make sure you have easy access to shade and air conditioning. Other than that, just be ready to dodge a shower or storm anywhere along the Tennessee side of things. In other words, this is a very typical summer yard sale forecast (ha).

I will say that most of the guidance keeps us rather dry from Thursday to Sunday. However, there will be greater rain chances to our west. Any deviation in the pattern could put higher rain chances on us for those days. I’ll keep an eye on it!

Temperature is a measure of how fast molecules are moving. The faster the molecules move, the “hotter” an object tends to be. The slower they move, the colder the object is. That’s how water ice forms. The molecules get so slow from the release of heat that water becomes a solid.

The confusion comes from how molecules act in space. They are moving very quickly, for sure, but there’s not enough of them to generate heat that you can feel on your skin. So, while the temperature may be high, the sensible heat that you would feel will be quite low.

Records

A lightning strike in Vance, Alabama struck a tree on a cattle form on this day in 1981. Fifty cattle, each weighing about 800 pounds, were taking shelter under that tree and were killed when the lightning left the tree and spread out along the ground.

It was a nice day! The morning low was a very crisp 58 degrees, and the afternoon high only climbed to 84. No rain fell.

News

We already have another area of disturbed weather to keep an eye on in the Atlantic. Right now, the chance of development is slim, but considering where it’s headed, it’s something to keep an eye on. I’ll be doing just that!

The Bigfoot conference in Gatlinburg this week was quite interesting, to say the least. We sure heard some stories! (haha) Seriously, if you have any interest in the subject you should check it out. I’m sure they’ll have it again next year. It was a sold-out crowd! Meanwhile, keep squatching! 🙂

Pictured below is me and the only friend I could think of that I could talk into going with me to this (haha). At one point, near the very beginning, Matilda looks over at me and asks, “Have you brought me to join a cult?” I just said, “It is concerning how easy it was to talk you into this.” LOL We had a great time and it was certainly an adventure I won’t soon forget!

Lil meteor shower tonight

The Delta Aquarids Meteor Shower peaks tonight through the predawn hours of Monday morning. Around 20 meteors will be possible per hour. So, it’s not the greatest meteor shower show but it’s still worth a look.

I saw one of these Wednesday night and it was quite impressive. It looked like a little fireball streaking toward the south.

Look toward the southern horizon and you may have better luck!

Sunday Story: My NASA Social experiences

It’s the moment you all have been waiting for! This story was printed in the Livingston Enterprise, Fentress Courier, and the Crossville Chronicle this week. But, I know that not all of you get those papers, so guess what today’s Sunday Story is? 🙂 For those of you who read the story in the papers, scroll down to see more pictures at the bottom of this story!

I hope you enjoy!

Over the Moon

WeatherTAP’s Meteorologist Mark was chosen by NASA to cover the launch of the Falcon Heavy rocket, the most powerful rocket in NASA’s fleet today. Mark was also chosen to cover the Orion Ascent Abort mission the following week.

Out of the hundreds of applicants for each mission, Mark was one of only 55 chosen. Being chosen for back-to-back missions is unheard of.

In order to be selected for these assignments, called NASA Socials, NASA investigates the social media of the applicant and the quality of their social media posts. The process is quite selective!

The Falcon Heavy event began with a live taping of NASA TV. NASA Social participants sat in on a live taping of the show, which featured scientists who had been working on the projects going up on this launch.

Among those missions were six NOAA satellites that will help scientists better understand the atmosphere over the tropics. The tropics influence global weather, so it’s important for scientists to understand the tropics as much as they can.

These satellites are called “cube sats” and are no bigger than a shoe box. This launch carried a total of 16 cube sats, the largest ever payload for a Falcon Heavy rocket.

Another critical part of this mission was putting an atomic clock in space to help with navigation. As of now, astronauts rely on GPS information coming from earth, which takes up to half an hour to reach a spacecraft. This atomic clock will allow for near real-time GPS data.

The NASA Social group was then bused to the launch site, where the rocket stood so magnificently. How humbling to stand so close to something so powerful!

This was the first night launch of a Falcon Heavy, and only the third time the rocket had ever been launched. After three launches, a rocket becomes certified for use by the military.

The rocket lit up the whole sky when it blasted off! Mouths dropped. As the rocket climbed higher, it became difficult to see, but that’s just when the show started!

The return of the solid rocket boosters was the best part. As they re-fired, high up in sky, they created different colors in the sky that were wavy in appearance. It looked like the sky of another planet.

Then, the boosters returned! The sounds produced during all of this are amazing, shaking the ground you stand upon. Then, the third, main booster returned and once again the entire night sky lit up, followed by another sonic boom, as it headed toward a platform out at sea.

After a few days of rest, it was time for the NASA Social for the Orion Ascent Abort mission. Once again, NASA Social participants we were taken to the press room for talks from those who work so hard on these projects.

This mission was to test the ability of astronauts to abort during a liftoff, just in case something goes wrong. Participants were bused to the launch pad to see the Orion capsule.

Participants were then taken to a Crawler, the vehicle that transports rockets to the launch pads. They creep along at a snail’s pace, weighing nearly 18 million pounds! Tennessee River rock is used for the Crawler’s path, because it can’t produce sparks when rolled across.

The next stop was the Cryogenics Lab. This is where scientists work with liquid Nitrogen as a propellant for the rockets. It’s a low-temperature propellant that makes launches possible. Nitrogen is the steam-like fog seen coming from the rockets just before liftoff.

Liquid Nitrogen freezes things quickly. The Cryogenicist took a rubber bouncing ball and turned it into a rock-solid piece of ice in seconds. He then dropped it on the floor and it shattered to pieces.

The launch took place early the next morning. The sky glowed of orange and red with the rising sun. The craft was to be lifted to about 31,000 feet before performing the abort mission. At that altitude, the craft broke apart and the escape capsule was propelled away. It then fell to the earth and splashed down into the ocean.

The Orion Ascent Abort mission successfully tested the capability of astronauts to abort a mission as the rocket is ascending. Such escape mechanisms might have saved the lives of the Challenger astronauts in 1986.

As if all of this weren’t enough, a weatherTAP Facebook follower introduced Mark to a gentleman with the 45th Weather Squadron. These are the folks who make the weather forecasts for the launches.

With his military pass, he took Mark for an incredible tour. He showed him where the Challenger is buried. He showed where Neil Armstrong, Buzz Aldrin, and Michael Collins once parked their Chevrolet Corvettes, a gift from Chevrolet after they walked on the moon. He showed the defense system that will shoot a rocket down if something goes wrong.

He took Mark to where Alan Shepard was blasted into space, becoming the first American to orbit the earth. Back then, the rocket launches were within hundreds of yards of the control center and the control center was like a bunker. They had to do it this way because radio communication wouldn’t reach much farther than that.

The tour concluded with a visit to the command center, where everyone gathers for the launches. This is where the nail biting takes place. Everything has to work right for a successful mission, something NASA is able to pull off with incredible precision.

It has now been 50 years since American Astronauts left footprints on our beautiful moon. The next step is to sustain a presence there, like we do on the International Space Station. Then, we’ll head for Mars.

The inventions and technology developed for these missions will change our lives.

Can you imagine looking up at the moon, knowing there are stations of people there? Can you imagine the day we walk on Mars for the first time? NASA invites us all to dream big and look forward to the future. I say we take them up on that!

Pictured below is the night launch of the Falcon Heavy. Unlike anything I had ever seen, heard, or felt. What a night!

FalconHeavyLaunch

Liftoff! Ain’t she a beaut?! This pic was taken from a camera near the launch pad. That water tank releases all of its water during these liftoffs, not for cooling, but for sound reduction. The water keeps the sound waves from destroying the rocket. Did I mention these launches are loud? ha

FalconHeavyLiftoff

This was taken by my NASA Social friend, Tony Bendele. We got to visit the Falcon Heavy while it was on the launch pad. It was quite the sight! Notice those solid rocket boasters on the side are dirty looking. That’s because they were being reused for this mission.

FalconHeavyRocket

It was at this moment (pictured below), when the return of the solid rocket boosters created this nebulae in the sky, that this whole event surpassed the experience of me seeing my first tornado on Feb. 5, 2008. They are still very close in being #1 and #2, but this, if only for a moment, helped this surpass that experience. I promised that tornado that night that it would always be number one, but in the very, very early morning hours of June 25th, I broke that promise. 🙂

11_To the Moon!

The return of the Solid Rocket Boosters to earth. I just can’t explain the emotion.

SideBoostersReturn

Liftoff of the Orion capsule to test the abort capabilities in flight. The abort mission would take place at 31,000 feet. We were close to this sunrise launch!

OrionAscentTest

Everything worked like a charm. If only the Challenger astronauts had had this chance. Eerily, the smoke plume afterwards reminded all of us of the smoke plume left behind by the Challenger explosion. A sign?

OrionAscentAbort

Look to the left of center of the pic, in the blue, and you’ll see the capsule falling to earth. Smooth as silk.

24_To the Moon!

And all 24 sensors on board were recovered. In this test, the capsule did not use parachutes to slow down (due to the cost of the parachutes). So, they had to recover these sensors. The remaining part of the capsule will become the foundation for a coral reef.

I hope you enjoyed that and I’ll see you at the launch I get invited too!
