Wow, did not realize that temps in Central and Southern Texas dropped so low
Texas is in the center-south of the North American continent (1119 miles to the west coast; 1042 miles to the east coast from Texas centroid). When you factor in that cold air will always overpower warm air (cold air is much denser) during fall/winter, and that Texas is in direct geographic aim of all the coldest air (plunging down from the central-north Dakotas and Minnesota (the coldest places on the continent outside Alaska but n the US), you have a far greater occurrence of cold weather in southern Texas when compared with the tropical water surrounded central and south Florida (look at Florida as an island rather than a peninsula just for a second, and imagine all that tropical water surrounding it on literally 3 sides).
