Pattern Jammin' January

If we can get that wave separation like CMC was showing earlier watch out..def a step in the right direction but hard to get excited about anything the GFS shows
 
Based off the snow map on NOAA, that looks like a general 1-3" for Alabama and north of 85 in Georgia. In Tennessee it's a hit too and some areas have higher totals.

Too bad it feels like model cartoons given the way things have gone though.

EXACTLY WHAT IS THE ORANGE AND YELLOW SHADED AREAS ON THE 500mb??

Shading is vorticity or "local" spin. Vorticity is measured at this level 500mb or halfway up in the atmosphere (also happens to be nearly halfway up in the troposphere) where the air is generally "non-divergent", which is important because convergence & divergence in the lower and upper levels respectively can distort the vorticity field. Positive or cyclonic vorticity (i.e. local spin that's in the same sense as earth's rotation) is shaded on this plot in yellows, oranges, and reds. The sign and value of vorticity therefore can help you determine the type of weather system you're dealing with (strong positive spin = low pressure & vis versa) Vorticity, like warm or cold air advection for instance, can also create vertical motions in the atmosphere. In a very hand-wavy sense, similar to when you open the drain in your shower or sink, positive areas of vorticity create a "suction" effect on the atmosphere whereby simply adding positive spin to a column of air will induce rising air beneath it, thus creating clouds and precipitation. This same process is also what makes supercell thunderstorms so dangerous in that a rotating thunderstorm will have the added impact of this so-called "dynamic spin effect" that lowers the air pressure even more in the storm than from latent heating of condensation would produce on its own, allowing the storm to become stronger & live longer than it would have otherwise if it wasn't rotating like an "ordinary" storm.

This is probably about as simplistic of an explanation as I could provide!

Looks like the gfs

WELL LOOKS LIKE TT HAS FROZE ON THE FV3 PRECIP MAPS.. ANYONE ELSE NOTICE IT GETS TO HR 60 AFTER SKIPPING FROM HR 42?
 
I'm curious as to see what one of these dragging flurries thru does down here in this new wet pattern. For years the fronts would tilt such that I only got the crumbs when it pull thru here. The tail end would dry up as it passed the Ala line. By the time it got here it was 3 drops and a finger wave. Caa in the upper levels dried the air right out. If Atl got 4 inches of snow, I'd get a half inch, or a dusting. During the droughts I'd get just enough rain to dot the dust and the northern end of the front got good rain. Now, things have changed and I get rain like the fabled flood every time a front drags thru. Will this translate onto a front dragging in snow on the back side? I'm interested to see. The cold air needs to move into a more moisture laden air mass than I used to get. All the moisture was busy moving out of Ga by the time the cold air found me.
 
I’m guessing nada on 2nd storm? Euro looks like poop. From what I can see it’s leaving energy behind.
