TN Dept. of Agriculture tracking invasive spotted lanternflies
NASHVILLE, Tenn. (WKRN) — Tennessee is one of several states monitoring the presence of an invasive insect.
The Tennessee Department of Agriculture is keeping a close watch on the spotted lanternfly — a spotted black and red insect that could be mistaken for a butterfly depending on its stage of life.
Tennesseans asked to report sightings of invasive spotted lanternfly
'The early instar nymphs are more the size of, like, a tick,' entomologist Cindy Bilbrey said. 'As the adults come out, they're going to be more mobile.'
Researchers said the insect poses a threat to trees by sucking out nutrients. What the insects don't use comes out the other end in the form of a 'honey dew' that's conducive to black, sooty mold. Field crews have been out across the Volunteer State to prevent the insects from spreading.
'They're scraping egg masses. We have some backpack vacuums that we [use to] suck up the nymphal stage as well as the adults. We also do some chemical treatment with Bifenthrin,' Bilbrey told News 2. 'They don't bite. They don't sting. They're not a threat to humans.'
The first reported sighting was in Davidson County in Hermitage in 2023, then in Wilson County a few months later.

'A lot of folks don't send a picture. Without a picture, it's really hard for us to confirm or deny information that they're giving us,' said Bilbrey. 'They're not common across the state yet and we want to keep it that way.'

National Hurricane Center has made changes to forecasting – What you need to know
NASHVILLE, Tenn. (WKRN) — The Atlantic hurricane season began on June 1st, and since last season, the National Hurricane Center (NHC) announced that they made some changes to their forecasting. The National Hurricane Center has made several updates to its forecast protocol and graphics in order to improve messaging, accuracy, and more advanced warning. According to the National Hurricane Center, the cone of uncertainty will be 3-5% smaller than in years past. This will better pinpoint where the hurricane will go. The cone of uncertainty, also called the potential track area, is the forecast of where the center of the storm will be in the next five days. 2025 Atlantic hurricane season is expected to be busy: How that could impact Tennessee They will continue to make the experimental forecast graphic that includes inland tropical alerts. Tropical Storm watches and warnings, along with Hurricane watches and warnings, are overlaid on top of the cone of uncertainty. This makes it easier to see the scope of the impacts the wind will have on inland areas. Here's a comparison of the old look and the experimental look. Along with the addition of the inland watches and warnings, they also made some slight changes to the cone of uncertainty. The old way drew the cone of uncertainty with a different pattern for forecast days 4 and 5. Now, the 5-day forecast cone of uncertainty will look the same throughout. Continuing with the theme of improved forecast accuracy, the National Hurricane Center will issue alerts and forecast cones earlier for storms that have yet to form. This means the NHC will have the ability to issue tropical advisory products up to 72 hours before the anticipated arrival of the storm. The old way was just 48 hours ahead of the storm's forecast arrival. ⏩ The NHC will also start issuing a rip current risk map. This product was added because, according to the NHC, during the past decade, there has been an increase in surf and rip current fatalities in the United States. Below is an example of what it will look like. The rip current risk map will be issued when there is one or more named storms in the ocean. They will use information from local National Weather Service offices to determine the risk of rip currents. The National Hurricane Center said it would like more feedback to continue improving its messaging and forecasts. To give feedback to the NHC, go here.

Will Tennessee see the northern lights in 2025? Solar maximus peak could mean more chances
If you were up in the early morning hours of June 1, you might have been able to catch a glimpse of the aurora borealis that crept down into the Tennessee area. If you didn't, don't worry, astronomers predict people in the South may have a chance to see it again in 2025. On May 31, a coronal mass ejection (CME) — a vast plume of solar material — erupted from the sun and began hurtling towards Earth, according to The CME is a geomagnetic storm that comes in Earth's direction that has the ability to hinder communications but also gives us the brilliance of the northern lights. The National Oceanic and Atmospheric Administration's Space Weather Prediction Center stated on May 31 and into June that a G4 "severe" geomagnetic storm was emitted that had the potential to affect communication by hampering radio signals and satellites. On June 2, a G3 geomagnetic storm was also detected. The northern lights across Tennessee: See the photos and why we might see them again The geomagnetic storm is a coronal mass ejection (CME), which are large expulsions of plasma and magnetic field from the sun's atmosphere known as the corona, according to This is one of several coronal mass ejections and storms that Earth has experienced over the last several years. While these geomagnetic storms from coronal mass ejections can affect satellites and our power grids, they also create the aurora borealis effect. And when they are strong enough, they allow for the northern lights to be seen as far south as Alabama. Here's what you need to know about the storm and if Tennesseans will see the aurora borealis once again. Most likely not. The dancing red and green lights of the aurora borealis aren't an unusual sight for people in the northern part of the United States and in Canada, but in the South it is a rare treat. In May 2024, much of the country got to see them. In 2025, though, June 1 was the first time there was a chance that the aurora borealis could be seen further south. Recent predictions from NOAA have the northern lights dancing their way down to the northern states once again on June 2, but the chance Tennesseans would be able to see them is slim to none. Our friends further north have the best seats in the country for June 2's light show. States best positioned within the aurora viewing line include: Alaska Montana North Dakota Minnesota Wisconsin Michigan States as far south as Illinois, Iowa, and Nebraska may have a chance to see the lights, according to NOAA. In 2024, NASA scientists predicted that the solar maximum, or the next peak in solar activity, would occur in July 2025. This means the northern lights will start to get stronger and more frequent as the solar maximum approaches, reported USA TODAY. Solar maximum is expected in July 2025, with a peak of 115 sunspots, according to NOAA. 'How quickly solar activity rises is an indicator on how strong the solar cycle will be,' said Doug Biesecker, Ph.D., panel co-chair and a solar physicist at NOAA's Space Weather Prediction Center. 'Although we've seen a steady increase in sunspot activity this year, it is slow.' Even with slow activity, the peak in July could mean even more solar activity, including the geomagnetic storms that cause the Northern Lights. Meaning, seeing the aurora borealis in Tennessee again in 2025 is possible, but there are no guarantees. These slow moving expulsions of plasma and magnetic fields can cause issues on Earth, but are often heralded as a good thing for the light show they also provide. CMEs have been known to affect power grids, telecommunication networks and orbiting satellites and expose astronauts to dangerous doses of radiation, according to The expulsions are also the reason we get to see the aurora borealis in the United States without having to make a very long trek north. In short, the northern lights can be seen thanks to particles being released by solar flares from the sun and hitting the Earth's magnetic field. That colored glow from the aurora that we end up seeing is the particles interacting with atmospheric gas molecules. In this case, green and red light are emitted by oxygen. Blue and purple come from nitrogen, according to NASA. Tennessee may not be the typical place to see the northern lights, but it has been known to happen, according to The Tennessee Conservationist. When the sun goes through a solar discharge cycle, which is when the sun releases a large number of charged particles into space, the northern lights reach further south. Before May 10, the last time Tennesseans could see the northern lights were in 2023. There have been reports of the aurora borealis being spotted in the early 2000s as well. But since the sun is nearing a peak of a solar discharge cycle there is a chance for more light shows in the future. USA TODAY contributed to this story.

The Milky Way will be visible through May in Tennessee. Here's when to look
If the rainstorms break over Tennessee, people may just get a glimpse of the Milky Way this weekend. But if you can't, you have a chance through the end of May. Every evening we get a glimpse of the vast cosmos that is our galaxy with the different stars that twinkle in the night sky, but in May, the celestial light show is even more brilliant. The view of our home galaxy will be on display over the weekend and into the next week, and should be exceptionally vibrant, especially in the United States, in late May as the band arcs across the night sky. Here's a look at how long it should be visible and if Tennesseans could get a chance to see the cosmic event. Technically, you can always see the Milky Way, but some times of the year are better for viewing than others. The end of May just so happens to be that time. "Milky Way season," when the galaxy's bright center becomes easier to see from Earth, typically runs from February to October, according to Milky Way photography website Capture the Atlas. However, the best time to see the Milky Way in the Northern Hemisphere is from March to September. Peak days to view the Milky Way started on May 20 and go through May 30, according to science news website LiveScience. The best viewing time is between about midnight and 5 a.m., according to Capture the Atlas. The reason we can see so many stars during this time of year is due to the cycle of the moon and how high in the sky the Milky Way appears from our perspective here on Earth. At this time of year, on clear nights, especially with a new moon, Tennessee and the rest of the United States will have a good view of a fraction of the stars that make up our home galaxy. To get the best view of the bands, people should look toward the Summer Triangle. Which is "a shape formed by three bright stars" that span across the Milky Way, according to In the northern hemisphere, the Milky Way rises in the southeast, travels across the southern sky and sets in the southwest, according to To get the best view, stargazers should look on a clear night away from light pollution.
