This link explains the wind barb notation used above.
Wind map explanation: The first column lists ground level winds, the second column shows winds at 3000ft ASL. The numbers represent hours ahead of the current time. As you scroll your mouse downward over the numbers, you are looking into the future forecast. Note the UTC time/date on the map. Scrolling up and down will help you make visual assuptions about the wind direction and velocity trends.
How do I interpret this data?
What you probably want to look at is the 3000ft (2nd column) wind direction and velocity at 1800 UTC on the day you plan to fly. If the color is brown, then it is likely good for flying. If it is light blue (15-20 knots @3000ft) then it might be blown out. If it is the darker blue or higher, then it is most likely blown out. This is assuming that you plan to fly at a mountain site. For kiting and coastal soaring, the ground forecast should be sufficient. Always use your own best judgement and common sense!
