Rain -- is coming. Up to half a foot, maybe even more is expected from Boone, NC, south into the NAGA mountains. Above is the GFS forecast model predicted rainfall -- over a six hour time period, with 1-1.5" common over a the southern Appalachians from Roanoke southward.
I guess it depends on who you ask, because the HPC is saying most of the rain stays in the deep south.
What is causing all this? Three things.
A) Tropical storm Ida
B) A cold front is drawing that moisture up into our area, combined with winds coming from the East to only enhance the rainfall
C) A long wave trough entering the area, only enhancing rainfall, and slowing down the exit of the rain. INstead of it just up and riding out, a new low pressure will form off the Hateras Coast throwing moisture back in all the way til thursday.
