You probably didn't sleep much. Honestly, between the house-shaking thunder and the weirdly purple hue of the sky, last night's weather was less of a typical rain shower and more of a full-scale atmospheric event. It wasn't just your imagination, either.
The lightning storm last night was a textbook example of an "elevated" convective event, which basically means the storm was feeding on warm air high above a layer of cooler air near the ground. This setup acts like a literal drum. When that thunder hits, the sound waves get trapped and bounce around, making it sound way louder than your average Tuesday afternoon drizzle.
What Actually Happened Up There?
The National Weather Service had been tracking a stalled frontal boundary for a while, but things got spicy when a pulse of shortwave energy rippled through the mid-levels of the atmosphere. If you looked at the radar around midnight, you saw those deep reds and purples popping up out of nowhere. It’s called rapid intensification.

Lightning happens because of ice. That’s the simplest way to put it. Inside those massive cumulonimbus clouds, bits of ice (graupel) and smaller ice crystals are smashing into each other like a demolition derby. This creates a massive static charge. The top of the cloud becomes positive, the bottom becomes negative, and eventually, nature decides to balance the checkbook. Boom.
Most people think lightning only goes from the cloud to the ground. Wrong. Actually, about 75% of the activity in the lightning storm last night was likely "in-cloud" or "cloud-to-cloud" (inter-cloud) flashes. This is why the sky stayed lit up for seconds at a time even when you didn't see a distinct bolt hitting a tree. It’s just raw energy dancing between different pockets of charge miles above your roof.
The Science of That Greenish Glow
Did you notice the sky looking kinda... sickly? People always freak out and think a tornado is coming when the sky turns green or deep violet. There is some truth to it, but it's mostly about light scattering.
Deep clouds are packed with water droplets and hail. When the sun has set but there’s still light scattering in the upper atmosphere, or when city lights reflect off the base of a low-hanging storm, the water in the clouds acts like a filter. It absorbs the red light and lets the blue and green through. It doesn't always mean a funnel cloud is forming, but it does mean the storm is incredibly tall and holding a massive amount of moisture.
Scientists call this "differential scattering." If you were under the core of the lightning storm last night, you were basically looking through a giant prism made of millions of gallons of suspended water.
Why Your Power Stayed On (Or Why It Didn't)
Grid stability during these events has actually improved a lot thanks to automated "reclosers." You know when the lights flicker, go out for two seconds, and then pop back on? That’s not a fluke. It’s a smart circuit breaker testing the line.
If a branch hits a wire during a lightning storm last night, the recloser shuts off the power instantly to prevent a fire. Then, it waits a heartbeat and tries again. If the branch fell off, the power stays on. If the branch is still there, the fuse blows for real.
We saw a lot of "step potential" risks too. This is something the International Association of Arson Investigators (IAAI) talks about a lot. If lightning hits a tree near your house, the electricity spreads through the ground in ripples. The voltage is highest at the strike point and drops as it moves away. If you’re standing with your feet apart, one foot can be at a higher voltage than the other, and the electricity will literally use your legs as a shortcut.
Misconceptions About Lightning Safety
First off, rubber tires don't protect you because they’re rubber. They protect you because of the "Faraday Cage" effect. The metal frame of your car carries the current around the outside and dumps it into the ground. If you’re in a fiberglass convertible, you’re basically sitting in a plastic bucket during a lightning storm last night. Not great.
Also, "Heat Lightning" isn't a real thing. It’s just a regular storm that’s too far away for you to hear the thunder. Light travels much further than sound. Sound waves usually dissipate or refract upward after about 10 to 15 miles. Light? You can see a powerful flash from over 100 miles away if the horizon is clear.
How to Handle the Aftermath
Now that the sun is up, you need to check your stuff. Don't just assume everything is fine because the lights are on.
- Check the Attic: A "cold" strike can crack a rafter or start a slow-smoldering fire in insulation that doesn't show smoke for hours. If you smell something "ozone-y" or metallic, call the fire department.
- Survey the Trees: Look for "spiraling" bark. Lightning literally boils the sap inside a tree instantly, causing the steam to explode outward. A tree hit during the lightning storm last night might look fine today but could die and fall on your garage in a month.
- Electronic Triage: Even with surge protectors, high-end electronics like OLED TVs or PC power supplies can suffer "internal degradation" from a nearby strike. If your microwave clock is flashing, your whole system took a hit.
The most important takeaway from the lightning storm last night is that our atmosphere is getting more energetic. Warmer air holds more water vapor. More water vapor means more fuel for these vertical updrafts. This leads to more ice collisions, which leads to more frequent lightning.
It’s a cycle. If it felt like there were more strikes per minute than when you were a kid, you’re probably right. Data from the National Lightning Detection Network (NLDN) has shown significant spikes in "flicker rate" during these specific types of nocturnal frontal passages.
Moving forward, the best thing you can do is invest in a whole-house surge protector. They sit at the main panel and cost a few hundred bucks, but they’re way more effective than those cheap power strips from the grocery store. Also, keep your trees trimmed away from the roofline. A wet branch touching your shingles is basically a giant "Welcome" sign for an electrical discharge looking for a path to ground.
