Thursday 11:30 a.m. update:
Rain has become more widespread across parts of central and southern Ohio since this morning. Colder air is continuing to push in from the north, which has allowed for some snow to pop up on radar.
Areas that are dealing with this wintry mix are those along and west of I-71. This rain/snow line is oriented from SW to NE and is gradually shifting SE through this afternoon. That will allow for a brief hour or two of a wintry snow mix across Franklin county and surrounding counties.

Little to no accumulation is expected but there could be a nice coating on the grassy and higher elevated surfaces. This wintry mix will taper off early this afternoon with virtually dry conditions across central Ohio by 4 p.m. Skies will even clear out for some late day sunshine this evening.
Thursday 7:30 a.m. update:
Rain has slowly moved back into the region this morning and is staying light. Locations south of I-70 are seeing more widespread rain, with some heavy rain is spots in southeastern Ohio.
As far as any snow on radar, we’re not seeing anything yet in the region. Temperatures have been able to stay mild, with many spots still in the mid 40s.
Models have been trending a little bit faster with today’s frontal passage and also are running a little warmer. Both of these variables will yield less time for snow to fall and accumulate.
The changeover is still expected to occur late this morning into the early afternoon, with the bulk of the precipitation ending in Columbus after 3 p.m.
Right now, most areas to see a dusting up to a coating of snow, while some isolated locations could see a small measurable amount(Less than 1″).
Thursday 5:10 a.m. update:
Light rain continues to be scattered across central Ohio this morning. Temperatures have been mild overnight, starting out in the mid 40s across much of central and southeastern Ohio.
Models have been trending a little warmer and are starting to push this front out a little early this afternoon. Both factors go against seeing snow fall for a prolonged amount of time.
We’ll still see a changeover to snow late this morning into the early afternoon, but don’t expect much more than a half an inch or so to accumulate on grassy and elevated surfaces by the late afternoon.
After seeing our first flakes of the season on Halloween night, we’re now looking at our first measurable snowfall of the season for central Ohio.
We’re a few weeks ahead of schedule, but given the unseasonably cold air that will be sticking around these first few weeks it’s not that big of a surprise.
What will be a surprise is that many of us will be waking up to plain rain on Thursday.
You’ll need the umbrella as you head out the door and the winter jacket for when you get home.
That’s because much colder air will be building behind this cold front, allowing for a transition from rain to snow heading into the afternoon.
This front will be well east of the region in the afternoon, but moisture and cold air on the back edge of the front will allow for snow to fall for a few hours before ending in the evening.
Temperatures will top off in the low 40s early on Thursday and will quickly drop into the afternoon. The question is, will it be cold enough for snow to stick on the roads? Based on our model projected temperatures it will not be until after much of the snow has already fallen.
In order for snow to stick on the roads we really need temperatures at or below freezing for several hours. We have some of the necessary ingredients for snow to fall but not enough cold air before the onset of the event. A mild morning on Thursday and the front moving through earlier into the day is going to make things difficult for snow to stick to the roadways. Elevated and grassy surfaces, however, could easily see some light accumulations going into the evening.
When all the snow comes to an end, skies will clear and temperatures will drop even further. Areas of refreezing will take place into Friday morning for any locations that don’t happen to dry out enough.
As far as snowfall accumulations go, most of us will see a coating up to an inch of snow in spots. Areas far south will be looking for more of a dusting up to a coating while areas further north and especially northeastern Ohio will see additional amounts. Again, most of this snow you see on this map will be accumulating on grassy and elevated surfaces.
And if you miss out on the snow, you won’t feel left out on the cold! Wind chills will be in the teens across the state Friday morning. A blustery and frigid start to the day and we may has some areas dealing with some slick spots thanks to some leftover rain or moisture on the grounds.
