Where are you pulling the info from? Regardless, this is something I didn't realize I wanted but have already followed the relevant ones. I don't like all the third party weather sites and usually rely on NOAA, but this makes it so I will see the radar in the morning. Cool stuff.
Wait, isn't everyone using these since at least 5 years? A biking culture and frequent weather with intermitted showers has apparently clouded my view here.
(Simply google weather radar and the area you want to look at, and project the speed of shower areas to know when to leave the house and how fast you have to ride to stay dry..)
This plus a big monitor, my kids think they are in a weather command center ;)
