This week’s satellite image is from a few days ago over the Mid-Atlantic Region. This image shows clouds over the Appalachians. At first glance, you may suspect a mountain-wave pattern, based on the periodic nature of these clouds and their proximity to the mountains. However, for this to be a true mountain-wave pattern, the clouds would run parallel to the mountains rather than perpendicular to them. This instead shows strong winds fleeing from the high pressure system to the west, condensing Great Lakes moisture into clouds in a cloud streets pattern.
