4:30 Winter Storm Watch Update | Weather

I have been looking over all the new data as of 3pm this afternoon and I am holding my forecast strong as to what it was earlier today. As of right now I just don't think accumulating snow is likely in the metro Atlanta area tomorrow due to the fact that temps have been in the 60's and 70's for the last several days. With that in mind here is what my official forecast is for the metro area:

Atlanta and all surrounding counties: No accumulations

West Georgia from Rome to Carrollton and Lagrange: Trace to 1"

North Metro counties (Bartow, N Cherokee, Pickens, Dawson, Forsyth, Hall) A trace on the grassy surfaces

N Georgia mountains: Could see 1-2 inches

Here is the latest model analysis

The NAM has continued on a cooling trend in the cold core, which is a nightmare for weathermen to deal with. Basically this system is not going to produce snow based on temps at the surface, it will produce snow based on what is happening upstairs. That layer of cold air at the upper levels is colder at this time than the NAM forecasted it to be in the last run which means that tomorrow it will be colder than what has been forecasted today. That means that the models are trending towards more snow in the mix, but again the ground is just too warm to hold snow......

Black Ice

There will be a chance to see some black ice on Friday morning as temps will be falling into the upper 20's. We have had a lot of rain and that could be a problem...

Another update later tonight!
