Mackerel sky is supposed to forecast that the weather is about to change. This photo was taken yesterday afternoon, and it was indeed followed by snow/rain/slush/ice during the night and morning. As nights had been very cold for quite a while, the change to milder temperatures meant icy and slippery roads and streets. Weather warnings were issued, and in the morning, many trains and buses were cancelled. Luckily I did not have to go anywhere. I had ordered a home delivery of groceries, which even arrived on time (around noon), in spite of the icy streets.
My local newspaper, on their website, reported about extremely icy conditions in our city centre in the morning, though. Below are a couple of "slippery slope" screenshots that I snapped from their video:
