While it is possible to see your old site, the accuracy of the data is suspect. The wind speed and direction on my site is hours old and while I've recorded rain today, the old site does not show it. The temperature shown on the map does not match the temperature field of the display. In my case there is a two degree difference.
I've learned not to generalize too much. What works for me may not work for you.
For me, using the old site, the current conditions aren't accurate (not sure where they're getting these values) but the map, summary and graphs are fine.
Using the new site the current condition (once you get past the pre-school looking graphics) are accurate, the summary is, at best, way behind and useless, and the graphs are okay but not really useful since they only display whole degrees and don't update as often as the old graphs.
But again, YMMV
