Late reply but this may be useful to others in this thread.
There’s a real good app called EpicRideWeather that gives you hyper local weather forecasting for routes. You can upload directly from RideWithGPS, select a start time, average speed etc and then you get a pretty sweet set of weather data.
Second that this is a good app. Used it as an alternative to weatherbagel when that hasn't worked for me sometimes. I think you only get a few free uses on it then have to pay, I seem to remember though that I uninstalled it and reinstalled it and got some more free uses.

The wind direction map is particularly useful.
