For those who know MSP: Tonight in the snow, I noticed that flights arriving at MSP were landing by flying very low over Lake Nokomis, which would be from the northwest and then a bit later apparently from the west, flying very low from west to east along a path between and parallel to I-494 and Highway 62. I assume that this way a method to close a runway and use another one while the first one was being plowed, but it still surprised me to see what I thought were somewhat unusual flight paths that also looked very low. Does this make sense?
