A wide band of high
clouds on the edge of a boundary sheet has moved through the center of
Wisconsin this morning, preceding
heavier clouds from the southwest, a pattern repeated in the last 5-6
days. The difference this time is that
rain is predicted so as this first wave of pre-precipitation mass moves in, what aviaticus pattern will follow? It is mid-morning so air traffic has slowed
and so I'm not sure if it is a hiatus in the traffic or if a band of
dryer/warmer air is passing over but the water vapor map indicates it is band
of dry air. However cirrus are still moving in from the Southwest
but I can not tell if they are natural or aviaticus.
My prediction is that the persistent trails will cease during this present period of dryer upper air and just before the thicker clouds move in, they will again form. Any sky watcher north in northern Wisconsin
would be thinking that same thing as our aviaticus clouds drift north. Here are directional shots of the event.
Early this morning, looking east where the aircraft originate:
Two views looking south into the flyway (note white Horizon):
Looking North out of the Flyway to where the Aviaticus are drifting (note clear horizon):
