The difference a day can make

No sound track this is a silent video. Just a short time lapse video done with my iPad Mini and an app called iStopMotion. Over a two day period I made two time lapse clips and joined them together. The app was taking one frame ever 60 seconds from around 8 AM until 6 PM . The first day was grey and overcast with a snow squall in the middle of the day and  the second day was sunny and bright with clouds and chem trails racing across the sky.
