Opinion, please

Is this what you call a mackerel sky? Because both Uncle B and I think it is, but the robot says: “In traditional weather lore it signals approaching change, usually rain or unsettled weather within roughly 6–24 hours.”
Google Images search thinks it is, too, but there’s absolutely no change predicted for our weather for days and days.
Also
“Mackerel sky, not twenty-four hours dry.”
And
“Mackerel sky, mackerel sky — never long wet and never long dry.”
And
“Mares’ tails and mackerel scales make tall ships carry low sails.”
Phooey.
