I expect the prediction for snow amounts to be somewhere between six flakes to six feet. These long range predictions are a somewhat educated guess. Local weather forecasts cannot give a reliable forecast for even the next 48 hours. Of course the climate change prophets can predict the earths temperature with a tenth of a degree years in advance and soon I expect will announce the date and time of our climate apocalypse.
There is a reason weather predictions only go out 7-10 days and even that is a guess. I look at a website and can count on their predictions going out 3 days maybe.
We have an expression here in Texas: If you don’t like the weather, wait 10 minutes. It will change. Especially in the winter.
