I am interested in hear U.S. glider pilot comments on the pros/cons of all these sites for soaring forecasts. I have used them all at one time or another and find them generally comparable. But, some like RASP and DrJack do a much better job of locating convergence zones/shear lines. Geo-referencing data and ease of use varies a lot. The biggest difficulty is that archive and looking at past forecasts makes it difficult to do inter comparisons.

Your inputs will valuable to me as I am in the process of writing an article for Soaring magazine discussing the basic of Numerical Weather Prediction and how it relates to these soaring web sites.

I started using XC skies around 2010-2011 and thought it was easy to use and felt like I did not have to decipher much. I liked the XC Potential and other bar graphs. Very easy to use. I also liked being able to save My Map Profile for different areas. I'm still learning Dr Jacks and have been hesitant to use much due to XC skies was so easy. I stopped using XC skies for I thought it was not being updated. The copyright is from 2005-2012, and the future development was last updated April 18, 2009. The owner of XC skies is supposably in Salt Lake City, UT. I don't think that I am the only one that seems to think its no longer updated by looking at the XC skies discussion board.
