8 months ago I had a vision: what if we had a unified, track-based dataset of all severe events?
Still a lot of improvements I can make to the algorithm itself, but otherwise, looks like we have one now. I can't wait to see what we can do with this 👀

Awesome display of the release of KH instability (vertical shear instability) within an altostratus and altocumulus deck! I ❤️ clouds

A nearly one-week animation for Hurricane Melissa with infrared (IR) imagery on the left and its maximum wind speed (intensity) evolution on the right. The animation briefly pauses at landfall in Jamaica.
IR images extend about 600 km from the center of the storm to illustrate its shape evolution.

(1/2) Classic cold air damming setup in the Carolinas today. Weak low-level upslope flow that is unable to surpass the higher terrain beneath isentropic ascent/warm advection resulting in a cold and soupy mess (aka drizzle, fog, and stratus).

Melissa at 892 mb. Since 1966, only 4 other North Atlantic hurricanes reached surface pressures below 900 mb (unit equal to hPa). Maximum winds at those pressures also listed below:
Wilma (2005): 160 kt, 882 mb
Gilbert (1988): 160 kt, 888 mb
Rita (2005): 155 kt, 897 mb
Allen (1980): 165 kt, 899 mb
Wilma (2005): 160 kt, 882 mb
Gilbert (1988): 160 kt, 888 mb
Rita (2005): 155 kt, 897 mb
Allen (1980): 165 kt, 899 mb
Finally a dropsonde message got out. 892mb.
Lightning continues across much of the western semicircle.

The eye of Melissa is quickly becoming cloud-filled as it interacts with the higher terrain of Jamaica, resulting in some weakening of the storm. Still, the impacts have been and are going to be catastrophic.

That’s…not at all how this works. As the NHC’s wind field image shows, Jamaica is only experiencing tropical storm-force winds right now, with weaker winds elsewhere. The most widespread and longest-lasting impact has and will be extreme rain - for which the prep is rather different than wind.

One of those moments as a meteorologist where you can't help but admire the beauty of such a storm, but dreading and terrified of seeing the impacts to Jamaica and Cuba. A pretty awful situation about to unfold and thinking of Jamaica residents and I hope everyone is safe and okay.

It appears the earlier secondary eyewall merged with the primary eyewall quickly, similar what happened in Hurricane Milton. That merger may have paused intensification, but Melissa appears to be making its move to Cat. 5 tonight. Certainly has that look. Next set of recon. missions will be telling.

One thing I am watching closely tonight is the short-term motion of #Melissa.
Google DeepMind ensemble has been pretty consistent in showing a WSW motion beginning tonight, & this appears supported by the ECMWF deep-layer steering-flow as the hurricane becomes vertically deep. Diagnosed below ⤵️

Microwave imagery also showing the formation of an eye/eyewall, with convection surrounding the storm center with the exception of the eastern portion of the storm. Central pressure should continue to tank especially as the eyewall becomes more symmetric. Thinking of the people in Jamaica and Cuba.

A rather ominous look to Melissa this evening, with deep convection beginning to symmetrize and what looks like a vortical hot tower now wrapping around the southern and eastern portion of the inner core. Latest recon data already shows minimum central pressure down to 972 mb.

Really glad to see this being implemented in Arapahoe County, which is a very long west-east county extending from Littleton-Deer Trail, CO and basically stretches through a common location for a Denver Convergence Vorticity Zone to setup (and has a high frequency of landspout tornadoes as a result)
