so 3 above at ATL at 3pm? Wow.

I wouldnt be surprised if ATL is below 0 on Friday afternoon.

I don't believe this air mass is that cold. However, it would be amazing to see something that rare.

That’s in the morning. It gets ATL up to around 15 during the day. Still way colder than anything else

I'll be shocked if Atlanta gets that warm, especially if there's cloud cover.

It's about as cold as it gets...cross polar flow from Siberia

Yeah, don't expect that to verify, but I find it interesting that its sticking to its guns. However, both the Euro and the GFS show upper teens Friday afternoon, so its not totally crazy.

The image was for 9-10 am not quite the afternoon yet .. ICON does have high in the 13-15 range for Atlanta though which is down right impressive

This is the exact same time, late morning Friday, Euro. More believable, but still unbelievable.

 

[NickyBGuarantee]

Interesting to note much more energy in the NW at the end of the icon vs the other models at the same time. Could have downstream effects or could not.

If it verifies it will colder than the Christmas 83’ record. The high at KATL was 17 on Christmas Day that year. I personally don’t like being out and about in this extreme type of cold, but this will be a phenomenal thing to experience. Never experienced highs in the teens before.

Energy diving down from the Dakotas

It is really rare to see a temp drop over ne ga and the upstate like those being modeled. Besides the mountains slowing it down,, Normally downslope warming also keeps temps warmer. If temps such as the icon verify, teens in the afternoon in ne ga, sc..it will be exceptionally rare. The euro and Canadian show low 20s in the afternoon which is still very impressive. Truly looks like one of the most impressive cold frontal passages in decades..especially for the upper Savannah River Valley.

What's different than our usual frontal passage in Ga. is the flow will be nearly due west rather than NW. So the downsloping component will be minimized. That also gives me a little hope that any renegade snow showers that get squeezed out behind the front in the lingering low clouds with steep lapse rates make it out my way here to Atlanta's east.

Keep in mind the high temp on Friday will probably be in the 40s in Atlanta at midnight.

That’s a nice run to run change

I’m well aware of that.

 

[Myfrotho704_]

Personally I would want that digging wave farther west, but this is not far from a money look, esp for this range

 

[Snowfan]

18z GFS looking better this run.

 

[Mitch West]

What’s causing that piece of Northern stream energy to just basically evaporate like that? Just getting squashed?

 

[CaryWx]

Looks like a clipper but never turns

 

[Myfrotho704_]

This trend ? Rockies ridge and more blocking on top. Looks like the GFS is correcting its progressive bias here

 

[vsublazer]

They just updated my forecast. Still not expecting much but it is a start.
