Larian is a bit busy with Dragon Commander in the final couple of weeks of tweaks and fixes before it goes gold.
They're also working on upgrading the Larian Vault for better Kickstarter pledge management, which will still take another week or two.
I imagine that they probably haven't fully decided exactly what the weather effects and such will do, they didn't actually imagine they'd make the $1M goal. The update on that will come, I just wouldn't expect it until after July 3.
