Meteorology (Weather)/Winter Weather in Quebec
I hope you get to see this. I'm wondering how many days out does the accuracy of the prediction begin to diminish? I am going to Montreal and Northern Quebec next Friday 2/15 and although I'm looking at both Accuweather, Weather.com and the Canadian weather sites, I'm thinking it is still too far away 7 to 8 days to be accurate regarding both temperatures and precipitation. Can you, would you please enlighten me as to just really how many days out from the date I expect to be there Feb. 15 is really and truly the most accurate. I 'm guessing 3 to 5 days maximum. Would be very happy to hear back from you. thanks so much for your time.
2 days is best, then up to 5 days, then diminishes as you get to 10 days. The winter is less accurate then the summer.
