Forecast for both days is very fluid as far as wind speed goes. Could be a bit nasty on Saturday late morning / early afternoon. Will be chilly either way.

I've always looked at it this way: if you have limited days to get on the Lake / make fishing trips, then I'd probably stay home and get some work done that will free up time later on a better weekend. If that's not really an issue, then go. Even if the weather turns out fairly bad, you can still learn some things and still catch some fish. The 'ole saying about a bad day of fishing vs. a good day of work. :-)
