This will be an interesting one. Sure, the easy answer is linear, but right now the hodographs show they could become more favorable over a broad swath with a minor southerly shift in low level winds. Also, timing of some much steeper lapse rates and strength of the cap during Tues heating... So I think the day-of dynamic environment will play biggest role with this moisture return. Watching what happens overnight Feb 3-4 will be critical.
