C.G. the last couple times I've been getting higher than normal when speed and gust not sure if this is because of the issues you mentioned above
Today Wind speed -28 mph / gust 86 mph.
I figured it's something you know about or maybe a extra digit was added.... so I logged onto the natiional weather channal and they showed no gust but wind speed of 4 mph.
Hope this info helps a little (Note: this was Iphone app)
keep up the great job
