If anything, the NAM is snowier for us. Need to see the rest of them but the NAM really lays down some moisture over our region tonight. This is down to what we call "nowcasting" which is observing the trends that are happening now as a basis for prediction rather than putting so much stock in the models.
Still - look at the NAM total precipitation for the storm. It's got us in a mini-bullseye - almost 1.25 inches liquid equivalent. All snow and a 10:1 ratio would give us over 12 inches but with the ratios and losing some already this morning to rain and slush, it's less than that.
But how much less? Let's see the trends once the snow starts falling.
