HRRR has made some improvements early still got some work to do with moisture feed into GA but belief it will. If this dry up hole doesn't occur ATL gets CRUSHED

It still fills back in as the amp up air/moisture approaches from west and is still freezing rain before warm air "pushes' CAD out but if didn't loss that 2-3 hours or frz rain accumlations are 100% in the .3 to .5 frz rain in that circle with more to come.

I think ATL proper is going to struggle with temps going below 31. NE from there it’s going to end up ugly. I’m preparing for the worst .5-.75” ZR and hoping for a washout here in the low 30s

Too early to tell definitely Euro AI/ICON think not and the latest HRRR took a big nod to those as well it was more of a qpf matter not a cold matter. The qpf was a uptick from last 12z run so it maybe playing catchup if you got fill in that blip as mentioned with moisture ATL is areas to west of ATL are approaching .30 to .40 inches of frz rain and ATL is close to half thru the event
 
Something I haven't seen much talk about is the wind speeds towards the tail end of the event and then post event on Monday/Tuesday. Readings from the models are at a threshold that would prevent linesmen from using their boom trucks. Anyone who loses power should factor that into their amounts of time without.
Same applies with telco service. Ma Bell won't touch anything until power lines have been repaired and winds and roads are safe.

Oh, and if your power is fed overhead to your home, do what you can now to prevent the service line from being pulled from the meter mast on your home. Utility companies won't touch your service line until a much in demand electrician has made the house ready for service.

HRRR is not the only model to show this for metro ATL. FV3 and others also have light to no freezing rain/rain during Sunday morning. The main batches of precip are currently modelled in metro ATL as rain to zr Saturday night, and Sunday afternoon a heavy squall line with rain

FFC just sent this to out to media and emergency management partnersView attachment 188120
Shirley some of this in the EXTREME area would be at least some pingers...But I haven't seen it in the modeling. All the upper level soundings say ZR too...Thank god for underground utilities and bourbon

Have a theory on downstream impacts?
I really don't exactly know BUT I think this might imply a fill in on the high pressure and no escape hatch, more banana high pressure. It also could pertain to models and the energy flying around having it incorrect. All I do know is the what ContentWeatherGuy said. The northern and southern areas of this still could see HUGE adjustments between now and go time.

Reminder... during CAD events a lot of moisture can/will fall that is not depicted on radar.

Even on this run, with the dry hole , HRRR has 0.34” ice on FRAM for ATL.

Ok looking at that I can’t help but wonder if there might be FGEN forced band of snow develope much further south in the CAD than what we’re seeing now. If you remember it was about this time frame in the January 2022 storm that the HRRR started picking up on it
 
If only we did this 2 days ago…. View attachment 188141
Remember...these models will often latch onto an idea, self-correct in the short term (6-12 hours) with actual observation input, and then derail back to their flawed idea. I have a gut that we are going to continue to see this southern trend with every run of the short range/hi-res models....we've seen this 100 times.
