VIPIR is not a computer model as the term is generally used.
It's just a fancy-schmancy cool-looking 3D way to display radar info. It's not predictive.
I really have no idea (since I didn't watch the station) how it got perceived by you or portrayed by the station as a forecast model.
And it doesn't belong to that station specfically. It's a subscription product used by stations all over the country. They're being deceptive if they describe it as such, but it would not surprise me.
One thing I've seen several stations do, as well, is use the MM5 forecast model and portray it as "our" model, which it isn't.
May have to find some archived MM5 tracks....
You are incredibly annoying.
VIPIR is a bit excessive sometimes....
