I feel I should share this further look at this special situation. In the attached figures, the lower one shows the fronts connected with the low pressure (stormy area) over the lake area. The upper figure shows the radar which indicates bird movement. It is like the birds are flying into a corner. See how there is barely any movement (if any) on the west side of the cold front, where the winds are from the northwest and north, until you get well into the plains where the winds are lighter. The effect of front on the north is less prominent. It is weaker and the winds are lighter and more variable. But as the storm center moves eastward, it should exert more of a blocking effect.
