Jonathan,

MASA has a seminar at this Youtube link:

There is a fair amount of discussion regarding weather forecasts and particular web sites that offer aviation weather. Its one of the better seminars I've seen and I'd recommend it to anyone either getting back into soaring or merely looking to brush up on their flight planning. It focuses on wave flying but is excellent for any cross country flights. Thanks again to MASA for posting this.
