Its not common to snow in Texas, so the drama is understandable. have you seen news of snow in Middle east & moutains in Vietnam. People go completely nuts about it when snow drop. There were traffic jam in Vietnam due to people rushing to the mountains to see snow.
Its a matter of perspective. I have friends from Russia, & he came from South West Siberia city of Omst, where temperature dropping to below -50 deg c (you can do your own conversion) is normal. And thats the South! In the North, in Winter, there is not much difference from Atlantica in Winter.
In tropics, 78 deg F is chilly, 7o deg F probably freezing, & I also heard of people freezing to death in extreme coldness of 55 deg F in India.
