Plus, you know what the wind is at 2000' because you looked up the forecast before you took off, didn't you.
I'm sure that was tongue in cheek, but just to be sure, the F214 spot wind forecast of up to 9 hours earlier won't be terribly accurate either, of course. But if the spot wind forecast at 2000 feet is consistent with the surface wind (i.e. the wind at height is a bit to the right and a bit faster) then it gives some confidence in the area forecasts.
