My brother lives about 50 air miles from me and we see this often in signal reports.
Even when the propagation is not this active there are nights that our signal strength varies and we don't change anything.
I often check into the Ditch bank SSB net on Friday nights, I like to drive up on Mount Bullion about 3000 feet and park on a lookout.
At the extreme reach of my rx there are stations that some nites I can hear, and some nites I cant due to small variations in the conditions.
