Thanks. Google play doesn't seem to be able to find it, not by a search, and not by the link from their web page. I tried getting weather from their web page for a trip I'm starting soon, but I just got a "this is embarrassing" response.

But, google play suggested other apps, so I'll try them. I appreciate your pointer.

My dad is a farmer, and uses DTN for weather information. It's a paid service, not 100% sure of the price, but it provides excellent weather information. I see they offer a product tailored for transportation: https://www.dtn.com/industries/weather/transportation/

Their mobile site isn't the greatest, but it is usable. I've used it for trip forecasts before, it works well. Edit:one great thing is no ads, weather.com is unusable w/o an ad blocker, but this being a monthly payment=no ads to deal with.

Second recommendation for DTN. I know people who run small town radio stations who use it because they can't afford the other big commercial services. They all say it's great.
