Cone is created based on 95% confidence interval from prior storm projections

So 5% of the time they will be wrong and outside a cone

Why do you hate science?

It's 66% of the error range over the past five years.

Which, unfortunately, doesn't correct for the actual uncertainty of a forecast.

The NHC track Sunday had it going through Hammond.


Yes, it did. They’ll probably miss by 150 miles or so 60 hours out. 1.74 standard deviations from typical miss at that mark. A miss you’d expect about 1 in every 13 forecasts.

Certainly get far more detailed information here than most places on tv. It’s why I wish this bitching about the cone would go elsewhere while some of us are still expecting to get the worst of this thing.

But don't worry, I'm sure there'll be plenty more for people to complain about next week with potentially another Gulf system on tap.

Not 95%. Not even close actually. 95% cone would have captured Mobile and then some.

This is the typical bullshite before the big update at 4 on here. Models are done, got one plane in waiting for a pass, so people bitch about the cone.

You Mobile/PCola baws, got any questions, just ask.

It will likely miss the cone. I’m a big picture guy though, so I don’t get too caught up when the center of a storm misses by 150 miles considering the circumstances.

Pensacola question here - how do you think the weather will be around there on Thursday evening/Friday morning?

So one out of three times, it will be outside the cone.

We are on named storm 20, right, so that means 6 or 7 times so far this year, we should be outside the cone.

People want more precision, but that might not be possible given current tech and science.
