Can a little cupcake make a big cake better? (I’ve been watching too much Cupcake Wars)
First we start with two magnificent cakes. Add another small, but energy-packed cupcake and in this case, yes the combination makes a great storm greater.
Here’s a wonderful photo – a composite of high resolution polar orbiting satellite photos – showing swirling storms. Our storm is on the left, as seen today from space. It’s stuck here because the storm on the right is blocking progress on the jet stream highway. http://earthdata.nasa.gov/labs/worldview/

The map below shows the smaller storm in the jet stream passing over the Great Lakes on its way to bring the energy for the snow we saw today. It’s the little low pressure system just to the west (left) of the larger low in this map of the jet stream over North America on Thursday evening. The smaller storm starts to swirl to slip around the big storm, but ends up smashing into the big storm, extending it westward back over us and giving us the snow we’ve been anticipating all week.
