Um, you have a point there, QV. Strictly seen 'kwakkelen' in reference to the weather means not very stable weather where the temperatures dance around freezing point. Then, a few degrees below 0 centigrade, shortly after being followed by Ts above freezing point again.. and no substantial freezing period because thaw keeps returning.
But but, the word 'kwakkelen' has more meanings and can also be referred to as something being quite unstable, in a broader sense, with a more negative touch to it. Like e.g. someone's being bothered with minor health problems for a while. As in, 'Hij kwakkelt met zijn gezondheid'.. and believe 'ailing' is the English word there.
Jeeh, hard to explain here but most Dutch folks would immediately understand what was being meant using it in reference to the weather in what ever season. It refers to something being uncertain and unstable then. (for over a somewhat longer period of time)
Blahiah.
