Wow An OLD thread.
I think what ALL weather organizations miss, is TRENDS. So what if your temperature and wind speed, Pressure/Humidity sensors are off a bit.
It is the trend they need to look at. When pressure/Temp suddenly make a change (up or down) OH... the front has arrived at that station. I had someone Email me asking why my wind speed was often way different than a station 5 miles away, it took over 10 emails to convince him that you could line up 10 anemometers 10 feet apart and all 10 would read different.
I think NOAA really misses out for not counting our data more.
