Can you qualify in what ways they're better? A brief look at them showed they have a nice rain animation but little indication of snow-line; multiple forecast graphs, which strikes me as unhelpful; and somewhat friendly phrasing of written forecast information, but nothing radically better than I've seen on, say, wunderground. They don't seem to particularly care about temperature - in particular they draw no particular attention to freezing temperatures. In terms of data presentation, there's nothing as original here as the 'storm distance' timelines on weatherspark, or the snow depth and wind speed probability density graphs you get from weather.gov.
The use case here is "Hey, I'm going to go outside in a few minutes, but it looks like rain out there: do I need to worry about rain? Should I rush?" (Alternatively, if it's already raining: will it let up any time soon?)
Longer-term forecasts and temperatures are incidental.
