12/07/17 6:00PM Me, You, And Some Glue Forecast Package

Good evening.  This is our 6:00pm package with updated forecast accumulation totals for the area going off the newest data.

Models continue to shift heavy precipitation back in across Western North Carolina and now Eastern TN.  Some of this likely is overdone a bit but the track looks plausible given the current synoptic set up.  

 Storm overview has a few more variables thrown in.  The duration of the precipitation appears that now it will last longer, into Saturday.  Accumulations could be higher if we get into the highest precipitation rates with the system.  Accumulations will be limited by warm air at the surface and warm ground temps.  Winter Weather Advisory is up for the Southwest Mountains and the South Mountains of Burke, Cleveland, McDowell, and Rutherford until 7:00am Saturday. Snow is expected to start in those areas and accumulate in the next 12 hours. Thus the reason the advisory was hoisted.  That is for areas above 1500ft.  Our Appalachian Mountains should hold off on precipitation starting until after daybreak Friday.  Rain will mix in with the snow in all areas on Friday, limiting accumulations.  If temps do drop as new guidance suggests on Friday Night then accumulations could be higher.

 Cold Air arriving a bit quicker than previous forecasts. Low pressure tracking closer to the coast than previously forecast.  White over green indicates rain/snow.  Best snow for snowman making in the mountains.  Maybe could sled for a couple hours on Saturday Morning along and North of I-40.
