Hello HN,I live in northern part of USA where winters are snowy. Whenever I took long trips, I always wondered what the weather along the route is going to be. For those who live in northern USA, you know weather can change frequently, so when you're traveling matters a lot, not just the route.To solve this problem for myself, I built https://navimodo.com/. NaviModo calculates the route, and then checks weather along the route based on your start time, and displays weather along the route. Change start time, and the whole thing is recalculated.I am not expecting any commercialization for this, just wanted to scratch an itch, and just did it. I have ideas for adding additional features (suggestions for when to take breaks based on bad weather, auto-suggestion of start time to avoid bad weather, etc.,) but will add more as time goes by.Any feedback is welcome!

Could you build this?

Yes This can be built in a weekend by querying standard routing APIs (like Mapbox or Google Maps) and sampling waypoints along the route polyline against a public weather forecast API.
