The Monday wintry event potential (12/8/25)

[kvegas-wx]

School closings gotta be coming soon for the Triad and northern counties, right?  If they closed for Friday, this is modeled as a higher impact event during school hours.  Really curious to see what WSFCS does here.

Roanoke County VA schools closed Monday.

I am going to South Hill and that vicinity tomorrow.

Can someone explaining freezing fog to me? I’ve been on this forum for 15 years and have never read about it. How is it similar to freezing rain? How/why does it occur?

It’s very rare around here, which made last night so interesting but like normal fog, you have to have high humidity and that saturated air super cools into droplets. Those droplets then freeze on surface objects like freezing rain, but the main difference being that these droplets are tiny - much smaller. Think steam in a bathroom after a shower vs the water coming out of the shower itself - similar concept. It’s a lot more common in coastal communities that get cold: i.e. New England, Seattle.

Freezing fog is not really a meteorological term, Pearson said. In order for it to form you need items or an object near the surface to be below freezing temperature, he said. This could include, trees, power lines and power poles, fences, tall weeds or cars. The air above the ground has supercooled water droplets in it, that might be just below freezing but are still in liquid form. 

Once those droplets come in contact with something at the ground or just above the ground freeze on contact with the surface of that object, Pearson said. Most often, freezing fog does accumulate on trees and power lines and if the wind is calm or maybe even light, can make a very picturesque scene as the supercooled water droplets turn into ice crystals (also called rime ice).  If there is some wind, then the water droplets will just form more as a hard layer of ice vs the more crystalized picturesque rime ice.

Thanks. I asked google but prefer asking an educated person, not AI. I just received a weather alert for freezing fog in the morning and didn’t understand. I’m in Raleigh.

Already down to 38 in Greensboro. Dewpoint 33

I haven’t got milk or bread yet. This is too  early in the season but I’ll take it.

[WinstonSalemArlington]

One thing that is different from Friday’s system is it’s significantly colder tonight in the Triad than it was this time Thursday night. PTI is already just above freezing, at 35.

The HRRR is to far north compared to almost every other piece of guidance. Let's see what the 0z Nam. NEST shows

If you take a blended approach I think it's not too far off. Especially after looking at the new Nam and Hi Res Nam.

Better go back to Farmville I bet they get 4-6

[PackGrad05]

Both the NAM and HRRR want to redevelop moisture across central NC around 7-10PM

[wncsnow]

Hi Res Nam. Should be at least some coatings in northern NC. If a band sets up maybe an inch or 2.

[Buddy1987]

NWS just dropped the hammer and upgraded ROA over to LYH to a Warning. 

[BornAgain13]

Still looks like we get a solid event up this way. Just to my north Advisorys have been upgraded to Warnings! Gonna be a nice narrow stripe of 4-6"+ somewhere
