Severe Weather Threat - October 18th/19th 2025

It’s also windy behind the cold front as well also cloudy cooler and rainy too

A bit nervous to see what the damage looks like from the Yazoo City tornado. That couplet wasn’t weak by any means and had a fairly sizable TDS.

Oh I see gotcha I haven’t seen anything come across for that yazoo city tornado

Yeah gusty here

Leaves will be gone before peak color here as they are all falling off from the high gusts.

These tornadoes are happening in a horrific environment. I have to believe that terrain is doing wonders here with the system.

This is a perfect example of how tornado forecasting will never be perfect. Absolutely no model today suggested strong low level shear for this to happen. Nothing to indicate tornadoes whatsoever, this was all the work of terrain and likely microscale storm influences

100% terrain induced. I grew up in eastern Kentucky right on the Virginia border. I have observed countless times storms cross into the southwestern Virginia or northeastern Tennessee higher elevation areas and immediately either drop a tornado or go tornado warned. It’s not as well known as Sand Mountain in Alabama, but I believe the terrain in those areas induces tornadogenesis or rotation pretty often.

So tougher to issue tornado warnings because happens so quick?

That, or some offices deliberately have a policy of not over warning for spin ups in a large line segments. BMX comes to mind.

Also due to the fact the rotation was likely concentrated at the low levels explaining the lack of a velocity signature because the radar couldn't scan down to that area of the storm, it's normal for these to be unwarned but hoping that this was more mostly trees and didn't hit those houses as suggested in Nick's post. A spinup QLCS threat beginning in the Toronto area too that has low level shear with it

This may be the worst ever environment I've seen tornadoes take place in. According to mesoanalysis, only 100 MLCAPE is present here with extreme shear allowing for organisation in the upper levels. Horrific low level shear, then terrain enhancement causes this. Pretty weird.
