I like it. My first instinct was to click on the radar to expand it (maybe because I'm trying to determine if I'll need a kayak to get to work tomorrow in PHL). I like that the timestamps for the radar frames were converted from GMT/Zulu for me. Your hourly forecast is nice and clean. Have you considered adding greater detail to the precipitation icons? Percent probability or estimated total QPF? Either way, I think this is an easier presentation than the hourly weather graphs on NWS. Bottom line, I'll keep checking back to see how things develop. EDIT: Forgot to add - good job making the map responsive to zooming and panning. That is one thing that drives me nuts with many radar/map implementations.
