LOUISVILLE, Ky. (WDRB) -- How does it happen? One forecast Tuesday morning, another that night. As the days changed, so did the data. 

WDRB meteorologists analyzed the ever-changing models, and continued to up the Derby rain chances throughout the week. But some people still expected the sun to shine bright on our Kentucky home.

"You can't be tuned in every second to watch the forecast change day-by-day. If you don't, you're going to get burned sometimes because the forecast changes non-stop," said Meteorologist, Jude Redfield

Buckets and buckets of rain ended up falling. The Paddock turned into poncho city. The track was transformed into a sloppy swamp.

"We are as aggravated as everyone else, that that kind of rain event occurred. I mean, the most rain ever on Derby day," said Redfield.

He and the rest of the WDRB Weather Team explain it was a perfect storm situation.

"There was no way to tell, even Derby morning, that we were going to get three-and-a-half inches of rain in Jefferson County," said Redfield.

"One of the things you'll notice when you look at the extended forecast is, you never see a 100 percent chance on Day Seven," explained Chief Meteorologist Marc Weinberg. "If you ever wonder why, it's because there's uncertainty, and I can't tell you with a guarantee well into the future what's going to happen."

If you think meteorologists aren't feeling this one, just take a look at their social media pages.

One person writes, "Somebody paid y'all to say that (bleep). He was probably Churchill Downs and I hope you all get fined and lose their jobs over it."

Another tweets, "Can't local weather people do any better in weather prediction? Hardheaded. The worst. Too much Woodford Reserve!"

So tweet, Facebook, and Instagram with care, because predicting the ever-changing weather isn't easy.
