Yeah ...most of these radar loops really want to suggest the low center is ~ 90 mi S of BID ...which is definitely west of modeling, certainly at the very western edge of consensus envelope if that's verified.
I think these 6 to 9 hours are critical to the total evolution of this thing. If we get the center jump east out to a new low near the triple point axis of the lengthening occluded boundary then the previous head scratch solutions have merit. If however, this western low center - which frankly is already a slight bust in my opinion - remains more dominant, than the phasing evolution (which has only been non-committal and partial to date) may also be a more fluid determination.
All that said ... doesn't really matter. I have personally been obsessing over the fact that the governing synoptic evolution so favored phasing...yet failing, that the reality of this storm ginormous girth and mid level mechanics bowing so far back W was getting less attention; but is probably the same damn thing sensibly to a small storm making a closer pass. So what difference does it really make? not a lot.. .I guess for things to "make sense" ...it would be more settling to see this western solution work out... but, seeing as it has already to this point at least a little, may also be an acceptable compromise.
So...some philosophy to go with some obs. 30F ; 3" 1/3 mi vis S
