Light snow/sleet mix started around 5am and at some points it became all snow... then all sleet... then a very heavy mix. Just a few minutes ago I stuck my head out the window and noticed gigantic flakes with large sleet and some rain.
Temps overnight hung right around 33° and when precip moved in around 5am dropped to 31.4°. But even now temps are creeping up just a little. That's enough to keep our snowfall totals to nothing so far. Right now out the window:
Nothing more than sleet and slush has stuck around so far. And to make things worse it looks like a dry slot is moving in pretty quickly from the south:
This doesn't mean we won't see snow, I just think totals will be reduced. I now expect 4" here in Canal Winchester, but still as much as 8" just northwest of us on the other side of Columbus in Dublin. Webcams on that side of the city are showing all snow.
We're getting some of our heaviest sleet of the day right now. Looking out the window you might mistaken it for snow, but stick your head out the door and there's no doubt it's ice.
We're almost to noon with no snow, so that tells you that we're probably not going to see the snow until we get on the backside of this low, which could be at least a couple more hours. Right now we are right in the path of a warm plume of moisture being pushed up front Kentucky:
All radar returns are showing this as sleet as far south as the Ohio River, and all webcams around the city show nothing but slush and sleet.
There is plenty of backside snow with this system that would have to eventually move through our area, but as the low pulls away from its main source of energy, the Gulf, expect the snow to actually begin to die off quicker than expected from west to east. That means we may only get a handful of hours of accumulating snow.
The 5" mark looks impossible. Best bet now would be 3" for us in Southeastern Franklin County.
Almost as soon as I clicked submit the heavy sleet changed to heavy snow. Just like that, it appears all columns are frozen now.
Central Ohio snow emergencies so far. With this being the first major storm of the season, expect to see this entire map filled in from Pickaway County northward by the end of the day, with most under at least a Level 2.
The heavy snow has ended, with some light to moderate snow coming in from the west as the low slides away. So far here in Canal Winchester we have 3" of snow. Well under the 5" I predicted yesterday. However, as I stressed so many times over the past couple days, sleet and freezing rain can kill snow totals. And it did for us today. Without snow kicking in until a little after 11:30am we missed out on the heaviest snowfall.
The NWS has already put out a preliminary map that looks like my contours from yesterday... except less:

I can't imagine we will see more than another half an inch overnight. I'll have a full writeup tomorrow summing up the event.
