heh. It seems like on a coarse global scale the model physics always want to torch us toward d10, but we all know how those nuances sneak into the flow as we close in and we get those sneaky BDs or late digging troughs that offer just a bit of relief. There’s a whole lotta land to our west and that ridge generally prefers to feed off of itself out there...and then the natural wavelengths tend to want to recede heights our way especially with cooler waters to our NE. Of course you can basically reverse that terminology for winter.
