I know this model stinks but I don't like the scattered lighter precip. That would mean more ice. Ugh Screenshot_20210216-213514.png
 
To me this has the best footprint of where I think ice will set up at this point. You have one CAM that’s likely well overdone with the ice and one that isn’t enough. This is a perfect blend of the two.

Earlier AFD from MRX this evening. I'm at 17 degrees right now with a forecasted low of 20 ? Grasping because I desperately want to try out our new sled!

"I think the biggest factor to keep an
eye on will be surface temperatures tonight (Tuesday night) and
daytime highs on Wednesday. Sometimes the models don`t handle how
long a dense/cold air mass can stick around in the eastern TN
valley, and sometimes we are slower to warm up than models
previously indicated. 12z Models have come in slightly colder for
daytime highs on Wednesday indicating that they may be picking up on
this colder air sticking around longer than previously indicated. If
daytime daytime highs on Wednesday get stuck in the 30`s or
near/below 40 then we`ll not have as far to drop overnight to hit
that freezing mark... I may very well be wrong on this, but I think
keeping an eye on how temperatures are trending on daytime Wednesday
will be the first indicator for the predominant precipitation type
on Thursday morning in the Valley."
