Gray matter, talking clouds here, not to be confused with the theoretical and ever elusive 'Dark Matter' of the universe, will be moving out of Central Wisconsin starting in early afternoon. We should have some thinning residual clouds coat tailing those exiting thick gray clouds and that may be the best time for contrail formations and viewing. Later we have a section of low vapor air crossing our area and another possible total blue out where not even whiffs and needles of trails will be visible. Cirrostratus aviaticus clouds (milky thin cirrus layers) are not likely.
We will have good east to west high altitude air traffic at that time during the afternoon so it will be interesting to watch the trail development or lack of development during the transitions.
End of Day Update:
About noon the the gray clouds shifted out of the area and were tailed by high thin, but not transparent clouds that revealed the remnant of jets from the east west corridor as forecasted. The sun dog indicates the ice crystals and a fine medium for aviaticus formation:
Further west and approaching was the clear less humid atmosphere. Here the first break in this long cloud event a west bound aircraft laying a visible trail. This cirrus aviaticus dissolves as it passes through the blue zone, then appears again as it crosses over a thicker remnant of the cloud front:
The rest of the day was a tangled mix of areas of cirrus and clear sky allowing the formation short trails and a few persistent trail. Here a segments drifts by. No cirrostratus aviaticus formed all afternoon:
