No, its cant be trusted in the sense you interpret is. The cell size for the weather models is, I believe 12km square so the best forecast you can get is a prediction for that area. Within that area there are local effects which can generate cloud or rain or wind but in any case the forecast for the cell itself is a probability one rather than certainty. And since both you ans us are on the join between two air masses with the jetstream passing nearby, the probabilities that are in any forcast arent high.
