Looks like a great day. The key difference in the forecast today is the B/S ratio is a perfect score saying it 'should' be no problem to stay up....mainly due to stronger lift (than Tues) and much lighter wind. I suspect you will get tou about 4500'asl.

The 10AM forecast shows a perfect B/S ratio so you should be able to soar from 10AM on (in theory). Lift will be light all day tho.

Don't soar too late tho...you don't want to miss the party.

There's even signs of convergence as you head towards Chatham.
