We used to hear of the "Alberta Clipper" when the cold swooped in across the MidWest and NorthEast from up where Catty1 lives - this "Arctic Vortex," though, dropped further down, way down and had a swirling shape - it even briefly touched Florida, hit Tennessee and lots of the South ... Now that we have such good satellite imagery, the scientists and weather folks can see larger patterns than they used to be able to, so see the bigger picture with things like this vortex! All weather is local, but is also part of a global system, and now that we have off-planet satellites, we can see that better!

Cocoa please, with some of that good bread!
