First things first... Here is a graphic of total snowfall for our region. Courtesy the NWS Jackson
Now let's look to the future. This next system has already sparked a Winter Storm Warning & a Winter Weather Advisory.

So how will this hit us?
That's the simple rundown. Here are some model runs and how each dipicts the system as it comes into the region.
GFS 10pm Weds GFS 1am Thurs GFS 4am Thurs GFS 7am Thurs GFS 1pm Thurs
NAM 1am Thurs NAM 4am Thurs NAM 7am Thurs NAM 10am Thurs NAM 1pm Thurs
The GFS is wetter and it is quicker. The snow arrival is is earlier and the change over happens a touch earlier as well. Both are right on target with the icing potential. So I have put together an updated map showing what is what!
I think there might have been some confusion about this graphic earlier. What I am higlighting here is "BEST CHANCE" meaning these areas will more likely see this type of precip for a longer period of time.
