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.

Bertie

From which source?

Can't you read? Me. I just told you. Moi, Ich, myself with my own eyes.

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

Mine are for high alt. The wx service wont tell you the wind at the top
of every peak, that's YOUR job to extrapolate.

Bertie

I don't fly high alt -- I fly between 5-14k.

I know what my job is -- thanks, and therefore how to extrapolate.
