Out of all the stats that will be in history books from Melissa, this is the most astounding to me. GLM data was recording a peak flash rate of 700 strikes per minute — nearly 12 per second — as it made landfall on Jamaica. That’s rewriting our understanding flash density in tropical cyclones.

Dream job alert!

A beautiful loop illustrating forward-propagation versus supercells moving right against the mean wind and ultimately the difference in net motion.

Given the storm environment, this is an almost guaranteed derecho across the northern plains. Eventual absorption of the pair of supercells ahead of the line will occur over the next hour w/ an exceptional damaging wind threat continuing w/ episodic tornadoes through tonight as the bow echo matures.

Streamers vs operational meteorologists: I want to make something very clear. Holding the responsibility of issuing a tornado warning while balancing accuracy and expediency is diametrically opposed to sitting in your Secretlab gaming chair pretending to understand the weight of those decisions.

Central Oklahoma wildfire outbreak.

Today and tomorrow have the potential to be one of the worst consecutive day outbreaks in the US in a long time. Day 2 High Risk issued for Saturday. While you may check the weather often, friends or family may not. Reach out to them. You could be the voice they need to hear.

The importance of the NWS will be on full display through Saturday with multiple outbreaks of severe thunderstorms, including damaging, long-track tornadoes. In addition to the severe weather threat, a wildfire outbreak is also possible on Friday fueled by very strong winds and dry fuels.

This morning was the most significant (and coolest) hoar frost event I’ve seen in Colorado and perhaps anywhere outside of the mountains. Absolutely beautiful.

We officially have thundersnow near the Gulf Coast - what an incredible event.

An extreme event is setting for the greater New Orleans area. The maximum 3-day snowfall I can find is 2.7" which occurred on New Years eve in 1963. The official forecast calls for 3-6" in New Orleans which would shatter this record.

Just had a sample of the Eaton Fire ash that is in my driveway run on the department XRF. Is there titanium (new house paint)? Yup. Lead (old house paint)? You betcha. Heavy metals? Check. Treat that ash like it's toxic folks (because it is)

Very sad news. I learned more about severe local convective storms from Chuck Doswell than anyone else. He was a friend and mentor.

#AMS2025 was as energizing as always, connecting with so many and seeing the incredible research originating from great minds within this community. What I’m taking home with me this year was a quote that I saw on the side of a random building: “You can do anything, but you can’t do everything.”
