You can add individual stations and then view all pertinent info. Clicking on each segment (i.e. temperature) opens up a more detailed view showing temp range over 1) last 365 days 2) last 30 days 3) last 7 days 4) yesterday and 5) today.
And in a move away from their website version you can select imperial or metric for each element. Makes a nice change from all imperial or all metric.
Highly recommended!
