Walter,

I think you want to do the following:

1) Check the box next to "U-component_of_wind: Array of 32 bit Reals [run = 
0..86][time = 0..64][pressure = 0..25][lat = 0..180][lon = 0..359]" -- it is 
the third variable in the list.
2) In the "run" box enter "0:1:0" -- or whichever run you want
3) In the "time" box enter "0:1:64 -- to get all of the forecast timesteps
4) In the "pressure" box enter "0:1:0" -- to get 100hPa level
5) In the "lat" box enter "135:1:135" -- to get your latitude of interest 
gridbox
6) In the "lon" box enter "292:1:292" -- to get your longitude of interest 
gridbox
7) Click the "Get ASCII" button to see the data.

You may want a different (or multiple) run instead of just the first one.

Hope this helps!

-Lansing
