This is an excellent point. This is why I am super intrigued in the period. It doesn't appear we will be dealing with a strong cap. there have also been subtle hints at some EML plumes working our way...which *makes sense* given we may be on the southern periphery of the westerlies but as I alluded too earlier...when you're dealing with plumes as opposed to large-scale EML air...it gets very dicey trying to time then with appropriate features (fronts, s/w)
