My thoughta re that I agree with you but I feel if they were confident they would have issued some advisories...whoever did the AFD appeared to be in a hurry. All models, except for one, do show light QPF for us (I looked at 4...one shows nothing, one shows .01 or less, and two show somewhere between .1-.25)
All surrounding stations are playing it down...huntsville with 30/40 (tonight/Monday) pops...Bowling Green with 30/20 pops...Memphis with 30/30 in their metro area; however, the chances increase to 50/50 once you cross the border into MS...Dyersburg carries 30/30, all snow.
Interestingly enough, one models splits moisture and takes it to Nashville northward and Birmingham southward...not sure of the reason for that, but that's what it does.
Tonight will tell more...as you can see though, not very many people hyped up over it.
