There’s an old geology saying:
“Here today, gone tomorrow.”
The same can be said for winter in south Florida:
Cold blasts of air never last for more than a day or two before more warm (or mild) air moves in.
Not to mention our metric for measuring winter is very low.
A day that doesn’t rise above 70° F isn’t considered cold up north on the continent.
On average, Naples Florida gets about 18 of those per year.
