Update on the Sunday-Monday Storm

This looks like the "Big Dog" weather event for the Western Carolinas and north Georgia, since the cold, wet, and snowy Winter of last season.  Basically, in a nutshell, all the new weather model runs have come in wetter, stormier and more agreement, and now the Hemispheric Prediction Center (HPC) is on board with a strong cutoff low pressure parking itself in the most judicious position to maximize both duration and quantity of a Heavy Rain Event.
Somewhere between Shelby, Spartanburg, Forest city and Lake Lure could get upwards of 5" of rain from this 2 day storm.  Even more is possible in upper Rutherford County around Golden Valley to the South Mountain Chain of Upper Cleveland County, and again in the Great Smokies.  This is where true upslope flow will rush into the hills, wringing out an efficient moisture supply to the max.
Flash Flood Watches will likely be issued soon for the Sunday and Monday Deluge.
