A high pressure ridge is strengthening over the area, killing the wind.
Wind looks marginal today at Skyline you may get some rides on a big kite/big board combo.
Saturday is windless at Skyline. If you are desperate, you might check out the fields around Evanston for some marginal 8 - 10 mph wind.
Sunday is also not looking very promising.
Fortunately, it appears that the high pressure will break early next week.
