Network activity drives Browntail activity. Generally speaking the domestic air network runs Monday night through Saturday morning, and historically there are practically no domestic Browntails on Monday mornings as volume is trucked to the maximum extent possible over the weekend.
There is a wave of inbounds to SDF Sunday morning and 2nd Day departures from SDF on Sunday afternoon, and only a tiny handful of departures (primarily international) Monday morning. There's almost no inbound to SDF Monday morning, with the domestic network fully spooling up again Monday afternoon/night.
Postal volume has caused some significant domesticnetwork changes - there's now a 2nd Day outbound departure bank from SDF on Saturday afternoon, as an example, so that flight activity is changing somewhat.
