What’s the coldest temp someone has seen freezing rain at with this storm?

Trying to gauge what to expect at my place as we slowly rise in temp

Had a mix of sleet and freezing rain for a little while last night 18 degrees

Thought this was an interesting paragraph from the MCD:

“Heavy precipitation rates will likely warm temperatures a few
degrees which may limit freezing rain efficiency in areas that are
currently 31-32F. However, where temperatures are currently in the
20s, northeast of Atlanta and eastward, expect below freezing
temperatures to persist within the wedge. Additionally, a meso-low,
analyzed on the 17Z surface chart in east-central Alabama, will move
east into central Georgia which will alleviate any chance for
erosion of the cold wedge and perhaps reinforce the westerly flow
across northern Georgia.”
 
Welp this sums it up if not posted. We goin’ get it apparently.

Areas affected...northeast Georgia...western South Carolina...and parts of western North Carolina

Concerning...Freezing rain

Valid 251757Z - 252200Z

SUMMARY...Heavy freezing rain is expected between 19Z and 23Z this afternoon.

DISCUSSION...Persistent cold air damming persists in the lee of the Appalachians and into northern Georgia. An expansive area of stratiform rain will overspread this cold air this afternoon and result in moderate to heavy freezing rain.

Heavy precipitation rates will likely warm temperatures a few degrees which may limit freezing rain efficiency in areas that are currently 31-32F. However, where temperatures are currently in the 20s, northeast of Atlanta and eastward, expect below freezing temperatures to persist within the wedge. Additionally, a meso-low, analyzed on the 17Z surface chart in east-central Alabama, will move east into central Georgia which will alleviate any chance for erosion of the cold wedge and perhaps reinforce the westerly flow across northern Georgia.

As a result, moderate to heavy precipitation with temperatures in the mid to upper 20s will result in significant ice accumulation between 19Z and 23Z from northeast Georgia into western South Carolina and into portions of southeast North Carolina. Given the expectation for relatively efficient ice accretion and QPF of 0.5 to 0.7 inches, expect another 0.25" to 0.5" of ice accretion this afternoon and early evening.

Where exactly does Apple pull this data from?? I can’t find a 40 anywhere near here. Hell, I am sitting at 30.4 still and AccuWeather shows me at 31. Apple says 40?! .

Oh it says my temp is 28 right now, but I’ve been stuck at 19 all morning. Literally just got to 20 about 10 minutes ago

This absolute nonsense

I’m curious why you’re saying what Ella Dorsey tweeted it’s nonsense? I don’t follow you. I feel the idea of significant additional icing in the far E/NE/N burbs is likely based on them still being well below 32. Now regarding the amounts of “ice” she has, they seem high. Is that what you’re referring to as nonsense? I could easily see that much in terms of ZR though.

Based on experience with heavier rain during these setups, my guess is that it will bring down warmer air from above and raise the 2m temps perhaps a couple of degrees making additional sig accrural right in ATL highly questionable as of now. But it’s still so cold to the E and N that that may not help much, if at all. Let’s see how the relatively warm 850s affect things, regardless.

Interesting to see, this area always looked like ground zero for this one, so interesting to see some OBS out of there. We didn’t pay enough attention to their area since we don’t have many (any?) posters there, unfortunately.

Squal line is going to kill power for lots in Georgia. I’m out for a walk and these trees are sagging more than I thought

I can't tell exactly, but it looks like that is around .4" of a glaze, what did you see?

I've determined here based on some pieces I could break off elevated services that I received anywhere from .3 to .35" of ice accrual.

Those areas are not going to get that much ice accumulation. Cut the totals in half at best

I think the zr totals will be overdone at least here. The 3K NAM shows a heavy band of sleet.
 
Heavy Rain has moved in, it should bump up temps at the surface as warm air is brought down. 30.9F
