Clear Sky Clock Wind Prediction Accuracy

Hi, many times when I observe at Doughton Park, NC, the clear sky clock does not seem to give very accurate wind predictions. I wonder if the model takes into account topological concerns or is it a computational prediction of pressure isobars?

Thanks,

I don't believe it takes into consideration any topology in particular...
Besides that, I don't take all it says as 100% accurate, but it gives me a HINT of what could be... 8)

You'll get a much more accurate prediction if you go to the local aviation weather site. If you contact any local small airfield in the area they usually have a phone number for automated info which gives the winds aloft at varying altitudes. If you can get aceess to an online system, local PIREPS (Pilot Reports) get you real time assessments.

I used to be a pilot and the aviation weather facilities run through FAA are much more accurate than local weather channels, etc., especially for within 12 hour predictions very accurate. Anything past 24 hours is really a crap shoot.
