Global models advertising significant cold wave late month after the Sunday ?

The incoming winter system Sunday looks messy and far from ideal for snow lovers, at least for most of the Metro area as of now.

METRO ATLANTA in yellow shade and outline:

Most models agree that this system is something of a hybrid “Miller-A/B” leaning toward more of a “Miller B”. That is not what we want for widespread significant snow in a large area of the Atlanta Metro. We want the surface low pressure to ride along or a little South of the Gulf Coast.

MODEL AVERAGE LOW TRACK:

That kind of track/path puts the best cold air aloft too far North and allows for more of a “warm-nose” on the skew-T vertical profile allowing too much rain plus a wintry mix with help from the CAD (cold-air damming) aka “the wedge” which favors most snow in the higher elevations of the NE GA Mountains and the far NE suburbs, in other words the usual suspects. So as it stands now if you usually miss-out completely or get less of what you want then as of this writing that will probably be the case here, if you usually get significant snow or ice (freezing rain) with almost every system then you probably will with this one. YES THERE IS STILL TIME FOR THIS TO CHANGE OF COURSE.

GLOBAL MODELS AGREE ON BIG COLD SNAP COMING:

If true, this would be bad news for our energy bills and for Florida citrus. Too soon to be specific, these maps below will likely change in one way or another. Hopefully toward less cold and not worse.
