It's another week of temperatures being in the 70's and then it changing into the 20's the next day! That's a huge change in temperatures! I wonder why we have been getting really strong cold fronts like this recently. It doesn't usually get that cold in Houston during the winter it usually only gets into the mid 30's during regular winters in Houston. There have been alot of cold fronts that have brought the temperatures to near record lows every week. I think that it's weird that there has been such a drop in temperatures recently.
