Ok... The upcoming possibility is very complicated. It involves a cold-core upper level low. So the forecast will be very tricky even up to the event itself (if it even happens).

Here is a snippet of what the GFS is showing as of the 6z run:




Here is a snippet of what the NAM is showing as of the 6z run:




So you can see, the GFS and NAM are pretty close in agreement on the placement of the ULL. If things unfold anywhere close to this, someone in the deep south is going to get a good SNOW. Even more interesting, this critter takes its time moving out! But remember, this is still days off. There is plenty of time for it to disappear a la Groundhogzilla...

Let's hope the 12z runs continue the show!
