Great Plains lighting bolt spanning three states sets shocking record
Aug. 5 (UPI) -- A massive lightning bolt that stretched from eastern Texas to just outside of Kansas City, Mo., has been officially recognized as the largest recorded flash by the World Meteorological Organization.
The lightning bolt was generated by a major cluster of thunderstorms that swept over the Great Plains on Oct. 22, 2017, the National Oceanic and Atmospheric Administration announced Monday. Researchers used advanced satellite technology to capture the flash's enormous span, and they hope it will help them better understand how lightning affects people.
Despite the bolt having a horizontal distance of 515 miles, it was not identified in the original analysis of the thunderstorm and researchers took note of it during a recent re-examination, according to NOAA.
The World Meteorological Organization's Committee on Weather and Climate Extremes used NOAA's Geostationary Operational Environmental Satellite, the most advanced satellite technology available, to verify the length of the flash and recognize it as a new record, according to a press release from the organization.
Researchers had previously used data collected by ground-based technology to measure lightning flashes, according to the press release. The use of satellite technology allowed researchers to observe a larger area.
"Over time as the data record continues to expand, we will be able to observe even the rarest types of extreme lightning on Earth and investigate the broad impacts of lightning on society," Michael J. Peterson, a researcher at the Georgia Institute of Technology's Severe Storms Research Center and member of the committee, said in the press release.
The lightning bolt's length is about the same distance between Paris, France, and Venice, Italy, according to the World Meteorological Organization. It would take about eight to nine hours to cover the same distance by car and about 90 minutes for a commercial plane.
The previous record was for a lightning bolt that spanned 477 miles across parts of the southern U.S. on April 29, 2020.
The Great Plains region is known for its large thunderstorms that also give rise to lightning "megaflashes" that extend over expansive distances or have longer durations. WMO Secretary-General Celeste Saulo said in a statement that while "lightning is a source of wonder," it is also a deadly hazard.
"These new findings highlight important public safety concerns about electrified clouds which can produce flashes which travel extremely large distances and have a major impact on the aviation sector and can spark wildfires," Saulo said.

Map: Who may see northern lights as coronal mass ejection hits Earth
(NEXSTAR) — Several states, primarily along the northern border, may have the chance to see the northern lights on Thursday. A coronal mass ejection, or CME, was hurled out by the sun on Tuesday, NOAA's Space Weather Prediction Center said. The CME, paired with a coronal hole high speed stream, or CH HSS, is 'expected to cause geomagnetic storming' Thursday into Friday, according to an alert from the Space Weather Prediction Center. CMEs are explosions of plasma and magnetic material from the sun, while a CH HSS refers to escaping solar winds from areas on the sun that are cooler and less dense. Both are capable of sparking auroras that we can see on Earth. Current forecasting shows the strongest geomagnetic storming could happen Thursday, prompting a G2-level watch. Conditions are expected to weaken Friday, giving way to a G1-level watch. At these lower levels — geomagnetic storms are classified based on their strength along a five-point scale — the associated auroral activity may only be visible to those in the upper regions of the U.S. The map below shows where the northern lights may be visible on Thursday. With the exception of Alaska, the likelihood of seeing the aurora in the Lower 48 is slim and limited to parts or all of Illinois, Iowa, Idaho, Maine, Michigan, Minnesota, Montana, Nebraska, New Hampshire, New York, North Dakota, South Dakota, Vermont, Washington, Wisconsin, and Wyoming. Those along or near the red view line on the map may only catch a glimpse of the northern lights on the northern horizon. What still causes the plague in the US? The forecasting is relatively similar for Friday. Parts or all of several states may again have the chance to see the northern lights: Iowa, Idaho, Maine, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, South Dakota, Vermont, Washington, Wisconsin, and Wyoming. The strength of the geomagnetic activity and the timing of it could impact the aurora forecast. According to the SWPC, conditions are expected to strengthen between 7 p.m. ET Thursday and about 1 a.m. ET Friday. They may weaken through the day on Friday before ramping up again around 7 p.m. ET. When the northern lights forecast is weaker, it's often recommended to get as far away from outdoor lights as possible and look northward. Even then, you may only be able to see the northern lights by taking a picture with your phone.

Northern Lights Are Expected Tonight Thanks to a Rare Solar Storm—and It Can Be Seen Across Almost Half the U.S.
If you're in a few lucky states tonight, look up at the sky for a colorful show. The aurora borealis, a natural phenomenon that fills like the sky with undulating colorful lights, should be visible on Aug. 7 and Aug. 8 in 18 states, weather and dark skies permitting. According to the National Oceanic and Atmospheric Administration (NOAA), geomagnetic storm conditions could be sparked by an incoming coronal mass ejection (CME), making auroras in the night sky. 'A CME and Coronal Hole High Speed Stream (CHH SS) are anticipated to affect Earth with elevated geomagnetic response and dependent upon the orientation of the embedded magnetic field, potential exists for moderate storm levels,' the NOAA said in a statement on their website. 'Combined effects from a coronal mass ejection (CME) which lifted off the Sun on 05 Aug and a coronal hole high speed stream (CH HSS) are expected to cause geomagnetic storming on 08-09 Aug. A G2 (Moderate) watch was issued for 08 Aug with the onset of activity. A G1 (Minor) watch was issued for 09 Aug.' Even a minor disruption caused by the CME could trigger the aurora borealis. The exact timing of the disruption is unclear, so the potential aurora borealis could be visible any time between 11pm on Aug. 7 through Aug. 9. Tonight might be the best opportunity for spotting the aurora for the lucky residents of the affected states. Northernmost states are most likely to have a chance at spotting the aurora. The 18 states that might have a view of the colorful sky are Alaska, Montana, North Dakota, Minnesota, Wisconsin, Michigan, Maine, South Dakota, Vermont, New Hampshire, Idaho, Washington, Oregon, New York, Wyoming, Iowa, Nebraska, and Illinois. Though solar storms are unpredictable, it's worth going out tonight and looking up. For residents of those states, the best way to maximize the chances of seeing the aurora borealis is to find a north-facing vantage point that lets you see the horizon clearly, and ideally is as far away from light pollution as it is possible to be. The best time for aurora spotting is 2 am, when the sky is likely to be the darkest, but since the arrival of the solar storm is unpredictable, it's recommended to look throughout the night for the event. Downloading an app that tracks aurora can also be helpful for sky spotters who would prefer not to spend the whole night outside.

EU climate service says July 2025 third warmest on record
The European Commission's weather service said July 2025 was the third warmest month ever recorded. Photo by John Angelillo/UPI | License Photo Aug. 7 (UPI) -- The European Commission's weather service said July 2025 was the third warmest month ever recorded. The global average temperature in July 2025 was 62 degrees Fahrenheit, behind only July 2023 and July 2024, according to the Copernicus Climate Change Service. It was 34.25 degrees Fahrenheit above the pre-industrial average. The last 12 months, taken together, were also 34.75 degrees Fahrenheit above the pre-industrial level. "Two years after the hottest July on record, the recent streak of global temperature records is over for now," Director of the Copernicus Climate Change Service Carlo Buontempo said. "But this doesn't mean climate change has stopped. We continued to witness the effects of a warming world in events such as extreme heat and catastrophic floods in July. Unless we rapidly stabilize greenhouse gas concentrations in the atmosphere, we should expect not only new temperature records but also a worsening of these impacts -- and we must prepare for that." The average temperature over land was 70.25 degrees Fahrenheit, which is 34.34 degrees above the 1991-2020 average for July. "Global warming isn't going away; it will get stronger in the decades ahead, so the summer of 2025 is a clear illustration of how things will be," a researcher at the Norwegian climate research institution Cicero, Bjorn Samset, said.
