Someone linked my post from a few months ago on MSFS weather Forecasting and Planning.
I am doing a VFR VR around the world tour and still use the same method described in my original post.
Last week, for example, there were IFR conditions over Greenland for several days, however, the model forecasted a short window of VFR weather of just a few hours over my route.
I took note of the forecast and planned my trip. Sure enough, I completed my flight VFR and the conditions forecasted were very close to what I found on the sim.
I was curious and went back to the sim a few hours later and the weather was back to IFR. Just as forecasted.
For those of you that are interested: here is my original series.
