Tom,
Have you contacted the nearest airports? They can usually provide you 
with wind roses which are simple images showing the prevailing winds and 
their velocity over the course of a year month by month. We've done many 
designs in various regions and had no trouble getting this data from the 
airports.

Here, for example, is one for Syracuse, NY.

and another for JFK airport in NYC 
<http://www.epa.gov/ttn/naaqs/ozone/areas/windr/94789.gif>

These are a little different from the ones I am used to in that they 
only cover a seven month period but with 16 indicators over that time. 
The usual is for a whole year and 12 indicators, i.e. one / month.

 OK, this may seem dumb, and maybe I'm just not entering the right  
 search terms.... can anyone point me to a source for a map of  
 prevailing wind patterns (particularly upstate NY)?  Seems they've  
 got to be out there on the internet somewhere, but darned if I can  
 find one (that works or shows anything, that is....)
 Thanks
