What we do know is a beast of a Winter Storm is knocking on our door. As you can see below no one really knows what kind of snowfall we can expect. I have put 4 different accumulation maps for you on here from ABC3340, NWS BMX, NWS HUN, and BAMS from Barons Services (via Stephen McCloud). Just look at the different projection from each one. The models keep jumping from further north to further South, this system is being real difficult to figure out, nevertheless This is a significant weather storm and should not be taken lightly. Well as I am typing this NWS Huntsville has just issued a winter storm warning for their coverage area. They are saying we could get a small layer of ice as well as freezing rain is possible Monday afternoon. I am going to stay with my initial accumulation map I posted earlier.
