Weather has always been a variable. It is NOT static.
Take Pittsburgh. I remember one day in December or January, 1997-98 timeframe, and when I got up that morning, it was in the 70s. Sunny and beautiful. Unseasonably warm. By 5PM the same day, there was 5-6 inches of snow on the ground that was NOT forecast!!!!!!! If our weather folks cannot forecast 24 hours in advance what the weather is going to be, why would anyone assume a given area would not have variations in weather. The whole climate change bullsh*t is total nonsense. Weather is variable, always has been, always will be.
