Erroneous wind speed data...?

The wind speed data being generated by my Sky is really wrong.
Ever since it turned cold and snowy the unit has been increasingly unrealistic.
Below is a shot of my Sky in blowing snow and a shot of the data screen.
My other anemometer was reading 15-25 with gusts to 30.
The sky was reading 2-5 mph.
The direction reads correctly and all the other data is credible but the wind speed isn’t even close.
What is going on here?
