I don't buy this explanation and here is why. The computer model must be accurate or you will never be able to simulate an accurate outcome due to the dynamics of wind, pressure and temperature. All of which, if it is not accurate would throw garbage out of the predictions. If you are not going by real data then what are you using then?
Example of a predictive outcome based on garbage(data) in will equal garbage data out. What data are you using then for wind speeds and why is that data being skewed in the output
The differences that are being reported in the media is 100 miles an hour. How is that possible coming from real data?

As a side note I checked the accuracy of this by going to my location and checking all data and it is very accurate when compared to current temps and pressure and winds.

fyi:

Scientists have a new way to measure how fast the wind is blowing.

That's because over the past decade, scientists have learned how to measure the speed of the wind at the ocean's surface by observing how much GPS signals are distorted when bouncing off the moving water waves. Now, a new paper reports that such wind speed measurements can be used with confidence when conditions are right, even to measure the winds of hurricanes.

Improved wind speed measurements could help meteorologists better understand and predict storms, says Stephen Katzberg, a distinguished research associate at the NASA Langley Research Center in Hampton, Virginia.

In the early 1990s, Katzberg and colleagues at NASA were asked to evaluate a U.S. Navy satellite for a civilian application in global ocean altimetry. The U.S. Navy was beginning to use GPS in their satellites and the team became intrigued with the question of whether the GPS signals could reflect off the surface of the ocean.

"Normally GPS signals go to a receiver in your car or cell phones, but some of it reflects off surfaces," Katzberg told National Geographic. "It's an incidental thing that turns out to be pretty practical, especially because GPS now illuminates pretty much the entire Earth."

Technology that they use for satellite measurements is actually the GPS system and special x-ray detectors. The technology is already there and being used for this additional purpose. That is why I included the information about how they get the measurement data. GPS is already being used extensively and the resultant reflection off of the water let them calculate the movement of said water. The GPS signal is reused for this purpose. Now you are trying to tell me they are getting rid of the GPS system? I highly doubt that.
I also agree that if the system is not accurate in real time then what data are you feeding it every morning, noon and night and why is the data over my own location so accurate when they use the very same systems to show our current weather. In fact they enhance the system using GPS and the local overland radar is fed into the data as well. I don't understand this explanation that they are cutting the funding....
Is windy.com using real data or not and what is the discrepancy between the real time data and current data from the ground sources. Why would the system be so accurate overland but very "Smoothed" over the water?
Why is there a 100 mph difference between the current data shown on your system and the reported data from the media..
They are saying this storm is 185 mph sustained wind with 225 gusts, yet your data is 100 mhp slower.

Sorry some corrections here. Not x-ray but microwave satellites.

I also want to point out that why isn't real data being positioned at the old prediction data points. How do you check your accuracy then based on the predictive algorithm to the real data? Why was there no mention of this before putting up this site, seeing that the public has access to this site?
