I realize a weather engine is major endeavor. But are there any thoughts about flipping the model so SMP generates the weather and injects current conditions into X-plane? Historically, it seems like most real weather add-ons (FSX and XP) do a poor job at interpolating between METAR, causing abrupt cloud and wind transitions. Above all, we want the weather depiction to be accurate at the departure and destination airports, with no abrupt changes there. Seems like SMP controlling its own destiny would ultimately provide the best result. Regards Rich
