Oh my GOSH!

So, today the temperature reached 80. Not bad for the end of November. Tomorrow? High in the 30s. In the 30s! Today my husband left for work when it was 70ish and came home after the temp plumeted to the 40s; my children and I donned shorts, tomorrow we'll curl up near the fire and sip hot cocoa. This is craziness. Does this happen only in Texas? Are there others who get to endure 50 degree dips in temperature?
