I have added a little gadget in the right column labelled "Routing for Delivery". Clicking the link brings you to a webpage, which shows a collection of delivery routing recommendations by Cirrugator. This is NOT a forecast of what it will be when Cirrus departs, but rather the situation for a departure today. See the note on that webpage.
P.S. as you can already see from the few examples, the weather is still quite unstable
