In the Jan 2010 event, the confluence was modeled way too strong and a storm that was supposed to give us flurries gave us 7” here 24 hours later. It works both ways.
People will always fret even at long range but I took one look at your map and my 1st thought was a low is unlikely to be there. It’s just not a path I see them take. I’d say in that setup it either goes flat across NC and further south or it shoots west and then jumps.
We are talking about two different things. I’m not talking about heights relative to normal. Draw a curve from Montana down to Texas around and up to the Carolina coast. That’s what I mean by a broad trough. These troughs that look like a cucumber from Wisconsin down to Ga and back up to Mass ain’t gonna do it. For one they get booted out easily. They last a day. Broad troughs give you a supply of cold to our nw that can get tapped. It also leaves room for secondary development on the tail end of fronts that do sweep through. Just my take.
I don’t agree. If you want consistent cold and chances for small events that will work. Those deep troughs in the se might get you a big storm once in a blue moon but not most of the time is my experience
