The flight prediction still looks ok - it's the weather that will cause problems I think
The Weather looks worse than dreary. We will be half way up a hill, so the wind is likely to be a little worse, Not sure it would be feasible to launch. We have a 50-60% chance of rain while we inflate the balloon (takes about an hour to launch at our quickest!), and we will be doing this with a headwind of between 14 and 16 miles per hour gusting up to 33 miles per hour. Not easy to hold a 6 foot lighter-than-air balloon with gusts that fast! The weather is probably a show stopper.
