I use up to 10 weather forecast sites and the Windfinder for eyes ahead. As a Guide in the Sierras for 2 decades , this is the ONLY data we have to estimate the conditions for the trips . They interpret the raw NOAA DATA and then YOU interpret that condensed milk and Make Up your Idea( we say yogurt). The forecasts Have Been Off somewhat rather Badly as of late ( the last two Years) . Plan for the WORST and Enjoy what you GET , because that is it for that time .We Complain to the weather or God . The humans are a best guess Race , and they invented TP less than a Hundred Years ago...... before that it was a SPONGE on a STICK you dip in water , use then rinse ,dry, store. Don't get carried away with data or best Guess . Remember YOU are responsible for YOUR decisions , not Oprah . Cheers and stay SAFE Every One !! gst
