FS 9 Behavior with FS Meteo Weather Updates

Does anyone use FS Meteo with FS9? I have version 6.4 and it works fine but the updates every few minutes can be annoying. I realize there mignt be a pause as the new weather info is loaded in, kind of like a scenery load, but I also usually have a disruption of my airspeed, either slower or higher,with ovrspeed warnings if it is higher. It takes a few seconds to recover usually. I thought this might be due to a difference in wind direction, and sure enough each time the program updates the weather there is a drastic change in wind direction - I could have a 27 knot wind from 230 degrees and after the weather info is updated it could be from 90 degrees instantly. Is this normal? Also the plane may rock from side to side momentarily as if it were hit by something and then recover. I could have cloud cover and then after an update, instant clear. Thanks. Tom
