WAA snows are not the best ratio producers even into super cold air masses until the favored zones. Been here too long to rely on anything above 10 or 11-1. Best ratios as always are in a CCB or ULL pass. Stick with 10-1 and adjust higher if needed.
The AIgfs is like 3’ through the run with 3 storms with temps in the teens for every single one of them. Putting it here but that may be one of the weeniest runs I’ve ever seen
