Weather thread Re the Alabama F4:

What is spc?

I want to recall seeing one. Checking Twitter, and I do see them calling out almost the exact area almost two hours before the event.

I feel for those folks in Alabama. Such a random event. Good people down there.

In hindsight, this threat played out to be one that would typically warrant at least a moderate risk. However, none of the models truly indicated that this would be a setup that needed a moderate risk, would produce an EF-4 tornado, or that it would produce as many tornadoes as it did. It should be noted that the second strongest tornado was a high end EF-2, which was more on par with what I think people thought would happpen.

SPC noted in their mesoscale discussions yesterday, even before everything really got going, that they were concerned about the potential for a few strong tornadoes.

Hindsight is always 20/20, and they will certainly review all of the data and work on improving. But no, I don’t think SPC slipped.

Further, bad weather was predicted for the area several days in advance.

The real problem,if you want to call it that, is that tornadoes are, in the grand scale, very isolated.
Not like hurricanes where everyone needs to get out.
Too many people are passive, and frankly don't have a serious place to seek shelter.
