Warm air leakage may bring us snow

 The default weather (latitude dependent) for most of NA is dry, desert air at -50.  We get -15 around the Great Lakes, yeah!

Lucky for us, our boundaries are unstable to ocean tropical plumes.

A slashing Pacific plume brought up warm Gulf air, so we can have snow.  This warm air pushed back the -50 air.

When the south goes to -20, then we'll see what natgas does.  The first cold wave blew up the Texan Permian pipes.

ps.  

Is somebody going to say 'Polar vortex fairies' and 'dancing jet stream'.  They did find someone in the states to say 'solid jet stream'.
