FWIW 6z NAM pretty crappy this AM:
Forecast:
Reality:
Obviously this doesn't mean it will be right or wrong about the next system, but like the training over Knoxville, models still really struggling even as an event is happening. WV GOES 16 does seem to hint that there could be some additional development NW of current precip, but not much as of now.
Thankfully as of this AM the trend over the past 3 runs on NAM is for a system with a more southerly axis of heavier precip. As the above comparison shows though, who knows what will actually verify.
Euro still south too with the heaviest rain:
It also seems to be overdoing the northern extent of precip this AM, unless there is something radar is missing, always a possibility with the plateau.
0z Euro also tries to give our eastern areas a dusting next Friday with a clipper type system. Any guesses on how long it teases us?
