Those Wacky Winds

I've seen it mentioned to death, but mainly over water. But the insane wind shifts nearly render ASA useless. Descending into Las Vegas tonight I had a wind shift of 180 degrees. Crossing NORRA the wind shifted from 250 to 030. Note the FD below... NO 030 winds anywhere on the route. Then, to make matters worse, it shifted back to normal. Log is attached. Time of occurrence was ~ 4:58pm and again at 5:27pm. This is so unfortunate. I have used ActiveSky since the free version and loved it. ASA is almost unusable.MLF 177@11(-2) 175@13(-5) 341@15(-13) 280@31(-24) 268@43(-36) 253@47(-49) 257@45(-55) 258@46(-54) 260@49(-55) 259@29(-58)BERYL 170@12(-1) 167@15(-5) 325@14(-12) 283@29(-24) 270@37(-36) 254@43(-49) 258@42(-55) 258@45(-54) 260@50(-55) 262@28(-58)NORRA 162@13(1) 150@15(-2) 296@07(-10) 290@15(-23) 280@24(-35) 264@33(-49) 261@36(-56) 256@46(-54) 260@50(-54) 268@31(-58)SUVIE 170@13(2) 156@14(-2) 298@02(-10) 285@14(-23) 283@24(-35) 267@33(-49) 265@35(-55) 258@44(-54) 260@49(-54) 269@32(-58)KVGT 173@15(2) 153@15(-1) 116@03(-10) 302@08(-23) 293@20(-35) 270@30(-49) 266@32(-55) 257@45(-54) 259@50(-54) 268@33(-58)
