Watching it pour to my north last night and now to my south tonight. Only 0.50” here.

Another underperforming rainfall event. I can't remember the last time one overperformed. I bet it was the big flash flood back in August. Everything since then has delivered less than advertised.

I was looking back through old photos and I found a screenshot of a Euro run four days out from that storm. It had a foot here. Actual total: 0.5". Typical.

Light snow down here too. 33 degrees.

Conversely, we are going to bust high. It’s nearly 50 here. After a low of 12 this morning.

I got down to 12 and then shot up to 25 already.

The flow snow is actually hitting the ground here tonight. I’ve got a fresh dusting on areas where the sun melted the snow off the pavement earlier. Still coming down lightly.

I wonder how Gatlinburg is doing? They look to be getting blasted with flow snow now.

Radar just looks like normal NW flow to me now. That’s unlikely to accumulate down here.

I think I’m going to mark this as a 2.5” snow but it’s honestly a total guess. The sun did an excellent job of vaporizing it off the roads. The only slick spots are shady areas or areas exposed to the wind that are getting blowing snow.

It's just too cold for brine to be effective at these temperatures, no? They heavily treated the main road nearby, and it's all white other what they've managed to scrap or plow. The chemistry says brine can work down to near zero degrees without freezing. In practice it just doesn't often work that way. I think it buys about an hour of time at the very start of events with temps above 25. Then it get too diluted by meltwater and stops working.

This isn't going to be a popular opinion, but my many years of snow events at TDOT has made me very skeptical of brine. During the event last January we brined half of I-75 in Hamilton County and left the other half untreated. It made zero difference during the event.

I have what I would call heavy snow for the first time. Went sledding earlier and the tracks are filled in already.

I think we’ve gotten into some better forcing. Rates are picking up again here. Might clear 2”.

It’s going to be very hard to get a measurement for this snow. I think I’m at around 1.5” but in some places it’s double that and others are nearly swept bare by the wind. Almost nothing on roofs. 18 degrees.
