Certain models were definitely too far south with the snow.

Same here in Mason and I agree. I was not expecting to see much this far north. Some models did not even show a flake for Mason and I'd est a nice covering now too. House cam's show that my driveway is completely covered now.

Yessir! Tonight should be even better. I strongly believe ILN should issue an advisory like LMK did. Many areas won’t hit 2” but it should be hoisted for impact.

For the past 2 days it has looked like our best chance would be for tonight. Totally agree,,,, ILN has us at 1-2" which is a good call and they mentioned no advisory yet due to timing not being during the PM commute. They got enough salt and brine out LOL We'll see if the data trends any stronger with the upper low today.

I think their reasoning is BS. There’s plenty of third shifters, travelers, and truckers who drive at night. Plus there will likely be lingering slick spots into the Thu morning commute.

But ILN sucks so no surprise there. I swear they get worse by the day. They probably don’t like us over at OVWC cause we call them out and I know they see it.

It buys them more time I guess.... CB calls 'em out too.

We are going to end up right around an inch here most likely before it shuts off.

Quarter inch here in Deer park with moderate snow atm

I’m right next door and we definitely have more than that lol.

We’ve got at least a half inch here in Silverton eyeballing it. Of course that’s not an official measurement technique lol.

I assume I have the same at home. Probably 1/4" here in Mason atm.

Dew is now up to 10 at CVG, still holding at 14. Vis now down to 1.25 mile.

QPF received is up to 0.02" at CVG.

12Z HRRR shows a developing band of snow associated with the ULL moving thru between that 10pm and 1am window tonight.

I’ll take an” official “ measurement when my granddaughter is taking a nap, lol

Yeah I’d like to see some 1” reports for great verification but even if a little short, we still nailed it being further north.

Models way over did the incoming artic high. 1050s to 1060 MB my ass. It is more like 1048 to 1050 MB last time I checked the SPC meso page. Models did get the weak low correct own in the Gulf though.

An inch here. School was closed. Road’s covered

Still coming down nicely here in Mason. Heaviest I have seen it all morning.

Maineville/Lebanon roads are not good. Moderate snow currently.

I called in a WFH day, have multiple employees stuck on the road for over 2 hours now, lots of accidents. It doesn't help that the Ohio is flooding so some alternate routes are closed.

Inch officially at cvg

Bgoney wrote: ↑Wed Feb 19, 2025 9:28 am Inch officially at cvg

On 0.03" or so QPF. Snow ratios are probably like 30:1 this morning lol

An update from the boys for the rest of today.... they say 20:1 ratios. I'd say they are higher then that based on the numbers I am seeing.

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

Westerly mid level flow with a weak amplitude shortwave trof
and strong jet tracking across the Ohio Valley today. Axis of
weak forcing with H7 deformation axis hanging back across
Northeast KY into Southwest Ohio. This was leading to continued
snow across ILN/s southern counties. Although forcing is
generally weak and QPF is light the snow to liquid ratios close
to 20:1 along with favorable DGZ was leading to efficient snow
accumulations. Highest reported snowfall totals were across
Northeast KY where up to 1.5 inches was reported.

As this system translates east snow will come to end for a
period this afternoon. Will continue winter weather advisory
thru noon across portions of northern KY and a special weather
statement to the north of this area into southern Ohio for this
mornings light snow accumulation. Expect additional snowfall to
generally be a half inch or less.

Cold conditions continue with highs from the upper teens
northwest to the mid 20s southeast.

I can also report an inch of new snow this morning per house cams. Driveway is completely covered... can't see the cracks in the concrete or anything.

12Z NAM gives CVG 0.04" of QPF which would be around 1.5" of snow with ratios. Similar from the 12Z RGEM also. 1-2" continues to look good to my eyes for tonight.

Add the 12Z GFS to the above post.

Wonder if they will go with an Advisory tonight.
