I'm not an "it's a bust guy" I'm more of a "why are we trying to forecast so far out" guy.

But the forecast was right. Some pretty bad storms have hit today and will likely go on tonight. It's that people don't understand nuance and that no one was saying that the entire state would be leveled by a tornado today.

People don’t understand that wind and hail can drive a risk just as much as a tornado threat.

If you forecast a 30% chance of rain one day, and it rains, was the forecast right or wrong?

What if it didn't rain?

Say a political pollster forecasts candidate Ronald Trunk has a 33% to win the election, and Trillary Plinton has a 67% chance to win.

Ronald ends up winning. Was the forecast wrong?

How do you evaluate a probabilistic forecast when n=1?

They forecast for a week all hell was going to break loose statewide today. Schools got dismissed early and all extracurricular activities were unnecessarily canceled because of the week long doom and gloom build-up.

Because we have the models and technology capable of it. Generally speaking forecasts these days are pretty darn accurate - when you think about it, it's pretty remarkable that 7 days ago the SPC was able to forecast a severe weather outbreak in Iowa/Southern MN, and have it come to fruition pretty much exactly as expected. Even more so when you take into account how quickly weather can change on a local level day to day. We can't control the weather so percentages always come into play and it will be literally impossible to be perfect regardless of how far out you're looking.
