These days they're getting it right about 90% of the time.

My flight logs come with forecast winds for every waypoint. they are
generaly within 10degrees and 5 knots of forecast hours form when the
forecast was made.
Vis, winds, precip, are all forecast to an accuracy that would have been
thought impossible just a few years ago.

From which source?

I've yet to see winds aloft match the forecast except when very strong
(40 Knots @ 3000) or very light.

That said, I think the effect of the local topography is not factored
in or perhaps ignored (The Alleghenies).
