Like you, I watch the long-range forecast, but also wouldn't bet on the forecast to be right. I sure hope you are right. It looks like that solarium will need all those three weeks to be anywhere close to ready. The main thing for me is to be able to get all the "stuff" from the porch that had to be moved out, and that is stored in my garage/greenhouses, back into the room. I need those greenhouses empty to do my fall cleaning/disinfecting and need to build my plumeria greenhouse in the garage.
