Okay, looking at the weather in Duluth, MN for this weekend at Weatherunderground.com, it looks like Saturday morning will be rain and it has a chance of clearing up by the afternoon with winds out of the Northeast (not the best for hawk watching, but for sure better than winds out of the Southeast).

Sunday is showing a very small chance of rain with winds out of the Northwest. If you are only doing one day at the Ridge this weekend, I would recommend Sunday. If you're doing both, I would plan on sleeping in a bit on Saturday--although if you're jonesing for a peregrine they do show up on cloudy, rainy crappy days.
