From snowstorm to sunshine in Chicago

The weather patterns in Chicago are amazing.... The weather changed yesterday from 40 plus to less than 25 and this caused massive delays for airlines and 300 flight cancellations in Chicago. This morning, it is a very nice and sunny day and I am on my way to Dallas (with 3 hours layover to continue to Mexico City). It is going to be odd to stay at the airport and not be able to visit my home. Hopefully the weather in Mexico City is going to be nice.
