Default A good 12 hour soaring forecast goes bad

Good weather on the 12 hour forecast became bad weather on the 9 hour
forecast. Even worse in the cockpit. See the forecast maps.

It's enough to make me wish for validation statistics on soaring
forecasts of various durations.

Perhaps I can help. After 17 years chasing the wind
Hang Gliding and 5 years soaring I have identified
one absolute rule in weather forecasting. I don't know
why it works but trust me it does.

The 12 HR forecast did not have the benefit of fresh upper air data, as did
the 9 HR. Your best bet is to stick with forecast output from model runs
based on 00z and 12z data.
