A wintry mess is in the forecast Thursday morning

Mother nature is getting ready to deliver another round of winter weather to Central Ohio tonight and Thursday morning.

PROGRAMMING NOTE: 10 This Morning will begin at 4 a.m. Thursday. Tune in for the latest weather and traffic alerts.

A Winter Weather Advisory will go into effect in Central and Southern Ohio tonight starting at 10 p.m. That's because a storm system will move in bringing the threat for snow, ice, a rain/snow mix and possibly some sleet before turning over to all rain in the latter part of Thursday morning.

As of this writing (just before noon Wednesday) the scenario looks like this: some light flurries will move in overnight before turning over to some freezing rain as we march towards the morning commute. This will then turn over to a brief sleet or rain/snow mix before becoming all rain by late Thursday morning.

Snow accumulations won't be a major factor but light icing definitely has the potential to impact the Thursday morning drive. The current forecast thinking is that the change over from snow to ice will occur sometime between about 3 and 6 a.m. starting in the south and spreading north.

We'll keep the freezing rain threat around until about 9 or 10 a.m. After that, we'll see a brief mix before this turns to all rain and that will set us up for a chilly, wet Thursday afternoon.

I think the best chance for any freezing rain in Columbus will be between about 5 and 9 (maybe 10) a.m.

Ice accumulations look to remain on the light side but the timing of this system is going to be more of an issue. Because it's hitting during the commute we'll have the potential for slick spots at one of the more inopportune times of the day Thursday.

Generally, light glaze to a tenth of an inch or so looks to be the biggest threat with this system. Even after crews can get the roads cleared sidewalks and parking lots will still likely be slick so be careful.

Keep in mind this is a just a forecast and as we get closer to the event we'll get more data from the incoming system and therefore have a better idea of what we'll see as the day wears on. There's still a little disagreement between the most reliable high-resolution computer forecast models.

When I say high-resolution I'm just referring to the fact that they're they have a better handle on the terrain and their timing of the weather event is better.

One that we use is calling for a little more ice in Columbus while a couple of others are looking at just a light glaze. The forecast numbers above reflect the latter scenario. All of the high-resolution models are calling for a little more ice out in Western Ohio so it's good to see some agreement there.

We'll be monitoring the changes throughout the day and will post changes as necessary so keep checking on-air and on-line for the latest forecast.
