HRRR was trying for something on Saturday up in North Carolina.View attachment 105222

Not good for the Raleigh to Boone 421 corridor anything on Saturday would wash away treatments on roadways before the main feast.

It would also further solidify the CAD.

NAM closed it off earlier.

It also helps moisten the lower levels. Less moisture waisted cause it gonna be dry cold ?

Ok this is spicy... Check this out.

Euro develops an area of weak instability as our trough begins to develop a negative tilt and a 300mb jet streak develops (placing the comma-head region under the LFQ) . Simultaneously, our LLJ really begins to crank and approaches 60mph. The end result? The potential for slanted elevated convection capable of thundersnow/sleet/ZR combined with surface gusts perhaps approaching 40mph. This area of instability and strong synoptic forcing gradually progresses north northeastward into VA.

18Z Euro mean

NAM closed off faster but it actually looks weaker and it’s definitely further east

21 inches near Clarksville, lol, geebus

Most of you guys were not even here, or your parents, in January 1973. Atlanta got obliterated by an ice storm, we had no power for 11 days, it was fun at first for this 17 year old, but got old after about the 4th day. Ironically this started sat night into Sunday. And how about the blizzard a month later in central GA which dumped 15-24 inches. This was a La Nina year as well.

My brother was born in Atlanta on January 12th, 1973. My parents talk about getting to the hospital that day every time we have winter weather in Atlanta.

Nam looks a tick colder at 42

Hour 36. Little further south with the low.

ticks/changes in energy and guessing with this storm from what it looks early has been harder then usual, really just a weird feel to tracking a northern stream wave becoming a Miller B, lol, this is a first

 

[Benholio]

Hour 36. Little further south with the low.

And I guess a tick stronger and the high is a tick weaker. But such small differences not sure it's significant

 

[MichaelJ]

This did not make sense to me until I looked closer, the latest was from the last GFS run while the bottom graph was from the NAM 18Z, there is the difference, my bad for not checking closer

I believe HRRR had it just north in southern AR at the same hour.

1. Per @dsaur, temperatures were 32 on the Buckhead bank thermometer he was watching and official records had it no colder than 30-31 for the coldest for the entire January 1973 storm.

2. 1-2/1973 was during El Niño, not La Niña.

Ughh I think it’s a bit south lol
