Wintry Dec 8-10th Winter Storm

GFS: has our southern wave is a tick slower and weaker than 18z. Our shortwave in the NE is also slower. Not seeing big changes yet timing wise. HP is a tad weaker as well
 
The wave was looking weaker, but I'm not sure it's much weaker now at 90. The NS still looks stronger though.

Edit: And yeah, HP differences between small numbers are likely meaningless.

Even if the high is a tad weaker the slower northern stream wave digging deeper into the side of the Rockies high may allow for better timing of the cold high this run but we'll see..
 
This run looks likes it's going to be colder. More digging should allow for deeper cold

Low 20s and upper teens for temps with a High Pressure centered directly over Watauga County, NC Thursday. It matters when a system is trying to come in and moisten things up too quickly. ( Referring to ICON. ) Expect more models to start finding this preset condition of cold dry air soon.
