these temps in the mid 40s were always well predicted by models. HRRR clearly has many areas in the 43-45 range. Temps dive tonight with arrival of heavy precip. That was always the forecast

And yet for some reason the NWS only forecast 41 in Charlotte. Why? Its up to 46 in Charlotte now. A whopping 5 degrees warmer than forecast with about 2 hours of heating left in the day.

I’m south of 85 in the upstate and my temp is 5 degrees cooler than Charlotte atm

To be on the safe side on the call maps thread, I edited my post and lowered totals pretty much across the board for the exception of the mountains.

I am growing concerned the counties north of Raleigh along the state line could see something special. 2-3” rates during the height of the storm. Into Virginia as well. Potential for thunder snow and blizzard like conditions too as deform band moves through that area. Could be a sneaky surprise I overlooked way east of the mountains.

I was about to say...I was going by your location in your profile. There’s still a light S/E breeze here & holding at 40.

I’m pretty close to downtown Greenville and I am sitting at 39, and dropping.

For NE GA, the 0c line should be past that area by 13z up at 850mb. The 0c line is already slightly past Rabun county in GA.

we in for a surprise?

What’s your thoughts on ice??

Good deal. Keep us updated. We are in the Golden Strip area

We could, we have to keep watching radar trends and those temps.

Fv3! Fv3!

 

[Myfrotho704_]

Even tho the fv3 is probably to snowy, which can still happen, it's a model you can trust except it's snow maps on tt

 

[WeatherLC]

Fv3 upped ice totals for ne ga

Does this mean we might see more ice than expected or does this mean there is a possibility of some snow accumulation depending on the temps ?

How far southwest will the 850mb move?

Temps are falling here in Spartanburg.

We won't really know, determining how far southwest that 0c up at 850mb can be very difficult.
Edit: Also, the 0c line can fluctuate.

 

[SimeonNC]

I feel like a banana high may form.

The 2018 banter thread.

Thanks! This thread will top that, and easily for one event. All the best!

Why is Hart and Franklin Co GA in advisory when other counties on each side in warnings? I dont get it..

Banks county is in FFc.

 

[dsaur]

Well if GA gets backside snow, it won't be from the CAD, but from the CAA from the northwest as the upper level trough swings through.

Of course, but a good cad would leave some low level cold in place, and more easily reinforced when the ull brings it's own cold by A weak cad all erodes out, and makes the ull have to work all the harder, leaving a lot us of outside looking in.

850/925mb temps is running around 3°C in metro Atlanta according to the SPC mesoscale analysis maps. I don't have to go back and look at model guidance to know that's a couple degrees cooler than forecast for this current time.

EDIT: Actually 850s just dropped to 2°C across metro ATL (17z)

 

[droptines35758]

Temperature is 46° on I40 in Knoxville. 6° difference between here and Chattanooga.

 

[NoSnowATL]

The supercooling is happening in NE GA. I see some spots of sleet/snow. There will be more blue/pink on the radar within the next 20 mins to an hr.

Some of that yellow is prob sleet mixing in at times.

 

[Jimmy Hypocracy]

It’s really coming down here. I have several rain puddles. Some have to be at least 36” in diameter

 

[packfan98]

Real nice push of frozen precip into NE GA and SC on the latest HRRR. Quite a nice jump south and southeast compared to the last run.

 

[NorthGaWinter4]

Someone is gonna get a major surprise in NEGa. Jmo

 

[Snowflowxxl]

I will say that the HRRR is initializing far too warm for some places, such as far NE GA

 

[SimeonNC]

Okay this is alarming, both 925s and 850s have warmed and the 1038 center of high pressure over Ohio seems to have disappeared.

Edit: I am talking about NC.

 

[Cmr4407]

Just got to Maggie valley and the change over to snow was at 3700 feet by soco craft and tower temp do dropped from 36 to 35 on car thermometer.

 

[Myfrotho704_]

In all winter storms, my experience with the hrrr when it shows this means you get a really heavy burst of snow to sleet back to heavy snow and repeat

Wow ZR gets into north Fulton county.
