Finally, the models have aligned. We’ll see if it holds.
As you see below, heavy snowfall is on the way to the Flagstaff area. A winter storm warning is in effect from Monday evening through Tuesday morning. As you look at the image below, you will notice that Flagstaff is under the greenish section of the color scale. That should comfortably put it in the 12 inch or better range. The National Weather Service is forecasting 8-12 inches. Temperatures are going to be fairly warm during the snowfall, which could mean denser, less deep accumulations.
