Exactly.... you can’t get your hopes up unless those probabilities start going up inside of 10 days. Think of it like a coin toss. I can toss it a 100 times but my chances of getting heads is always 50% with every toss. Our probability of snow over a two week period as stated in previous posts is usually a certain percentage....your antennae should go up when the percentage goes above the average and when we are getting into the shorter ranges. Probability maps are just a quick and dirty way to see if our snow chances are trending better, worse, or about the same.
