One of the most insane thunderstorm I’ve ever seen just rolled through Davis, California. Local weather stations recorded nearly 0.50” of rain in 5 minutes. Temperature dropped over 20 degrees down from 70s to high 40s.

Video showing UPS Flight 2976 crashing shortly after takeoff this evening from Louisville after its left wing caught fire. The plane briefly became airborne before slamming into nearby warehouses, triggering a massive fireball that shot hundreds of feet into the air and ignited a blaze that has destroyed multiple buildings, with reports of people trapped. Smoke from the toxic fire is visible more than 10 miles away, prompting a shelter-in-place order within five miles of the airport. Rescue operations are underway, with three people on board the plane.

I’m not aware of an official UK dew point record, but the Euro model is forecasting dew points near 25°C (77°F) in England Wednesday evening. Ireland and Scotland could see similar dew points Thursday. This is summer humidity typical of Florida or the Persian Gulf. These unusually high dew points will make the nighttime heat even more brutal and potentially deadly for vulnerable populations and households without AC, which is most of the United Kingdom.

The Maui fire that tore through Lahaina is one of the worst wildfire disasters in US history. The town of 12,000 people is virtually destroyed, with at least 53 dead and many more missing. More than 1,700 structures have been destroyed, including entire neighborhoods. Maui is in great need of outside assistance. Imagery via :)

This was right when the massive thunderstorm began in Davis, California. In seconds it turned into a huge hailstorm, with rain rates briefly exceeding 5 inches an hour. 1.2 inches of rain was recorded just down the street from me in 20 minutes.

Insane timelapse from Hanalei Bay on the north shore of Kauai shows water levels rapidly receding. So far, no major tsunami waves or significant water intrusions have been observed. This is great news, but we’re not out of the woods yet in Hawaii, as multiple rounds of tsunami waves will occur.

I have truly witnessed an unbelievable thunderstorm outbreak in Amsterdam tonight. We’re going on 4 hours straight of constant lightning and downpours. At peak ~30,000 strikes were detected in 30 min across Netherlands and northern Germany, ~17 lightning strikes a second.

Day 2 midday update at Donner Summit as major snowstorm roars on. Extreme blizzard conditions continue with I-80 fully closed. Cars are buried, my chasing buddy Michael helped pull a stuck driver from a snowbank, semis are stranded, visibility near zero, and at least 1 foot of snow has fallen since 6 am.

Day 3 of the major snowstorm at Donner Summit. Periods of heavy snow continue, albeit less intense than yesterday. Cars are completely buried, and a rapid dig-out has begun before another 2–3 feet of snow falls tomorrow. Expect the highway to close again, so I’ve ended my snow chase and driven back down into the Central Valley. Yesterday’s conditions were the fiercest winter storm conditions I have ever covered or been a part of. We left the summit around 12:30 pm, as blizzard conditions persisted for hours. It was a complete whiteout, with no visibility beyond a couple hundred feet at any point. Even my chasing partner Michael’s car with 4WD, snow-studded tires and high clearance was absolutely no match for the storm. Visibility reached truly zero at times, and peak snow rates reached 4–5 inches per hour. Even though winds were lighter than in other I-80 blizzards, the extremely low-density snow made it incredibly easy to blow around. I chased the 10-foot blizzard during Leap Day 2024, several major storms during the winter of 2023, and experienced epic months like February 2019, December 2021, and January 2017, but the peak intensity of this storm puts it above the storm conditions I experienced during these events. Prayers go out to the victims and families of those who perished in yesterday’s avalanche near Frog Lake. A terrible tragedy.
