It should be noted that even the coldest solution GFS gives CMH only 0.9" of snow. It's just not happening for CMH, folks. Sorry.

Fixed.

I said before. south of I-70 I think is dead. At most you'll see zr/slop. But north of I-70 is still very much in the game. Last storm models didnt pick a final solution until the night before. (had me rain until the night before the storm) If that is any indication I would think we will have a better idea of temps tonight.

I'd be more concerned with the 18z NAM if there was one other model that shifted significantly NW today. A 150 mile shift in one run doesn't seem realistic... the 18z NAM at that.

Euro and UKIE have been ticking SE the past few runs. GFS moved a little NW... but more in line with the other models.

If the NAM somehow sniffs out this massive change first I'll be surprised.

Surprised CLE went with a watch so early. Pretty bullish. Smart of them to leave themselves an out.

...WINTER STORM WATCH IN EFFECT FROM THURSDAY EVENING THROUGH FRIDAY AFTERNOON...

STRONG LOW PRESSURE WILL MOVE ACROSS SOUTHERN OHIO THURSDAY NIGHT INTO FRIDAY. MUCH OF THE REGION WILL SEE RAIN THROUGH THURSDAY BUT AS COLDER AIR SPILLS INTO THE REGION THURSDAY NIGHT THERE WILL BE

A GRADUAL CHANGE OVER TO SNOW. THE MAIN CONCERN IS HOW LONG A PERIOD OF FREEZING RAIN OR SLEET COULD PERSIST AS THE AREA TRANSITIONS TO THE SNOWFALL. WINDS WILL ALSO INCREASE ON FRIDAY AS THE AREA OF LOW

PRESSURE PULLS EASTWARD ALLOWING FOR SOME BLOWING AND DRIFTING OF THE SNOW THAT FALLS.

SNOWFALL AMOUNTS BY FRIDAY AFTERNOON MAY BE IN THE 5 TO 7 INCH RANGE ACROSS THE WATCH AREA. ISOLATED TOTALS MAY REACH AS HIGH AS 9 INCHES. THESE TOTALS WILL BE IMPACTED BY THE AMOUNT OF ICE THAT WILL ACCUMULATE. IF GREATER ICE TOTALS OCCUR THE SNOWFALL COULD BE LOWER.

From BUF re: the track. I would have posted CLE's disco on the track but they didn't have any.

SIGNIFICANT SNOW BECOMING LIKELY FOR ENTIRE AREA FRIDAY... MODELS HAVE COME INTO BETTER CONSENSUS WITH TAKING A DEEPENING WAVE FROM OHIO VALLEY ACROSS SRN PA TO SRN NEW ENGLAND DURING THIS PERIOD. THIS IS AN UNUSUAL TRACK BUT STRONG CONSENSUS IN IT. THE ECMWF HAS NUDGED SOUTH A BIT FROM PREVIOUS RUNS...ERGO..COLDER... WHILE OTHER MODELS SUCH AS NAM, GFS AND GEM ALL JUMPED NORTH...WITH HIGHER QPF.

What an excellent discussion by CLE!

BTW, I was in Wooster last night and they didn't have more than 5" on the ground. In fact, it didn't appear that any place from Cleveland to Wooster had more then 5" on the ground.

These events make me nervous. The ride the line events almost win out towards the warm. I'm not going to get too excited yet. One of the other things I've learned this winter is that storms almost always move much faster than the models anticipate. I would take any max QPF, deduct 30% and apply a 10:1 ratio to get a realistic storm total snowfall.

I figured there would be alot more snow down that way. Sun may have done some damage yesterday.

CLE just copied and pasted their watch info in the disco. BUF and DTX had nice discussions... both offices favor an Ohio river track.

If tonights run go NW I'll jump ship. One rogue NAM run is enough to make you nervous. We basically ride the line with every event here. I can see the rain line making it up to MFD to YNG but not much further north.

If it does play out to a snow scenario, this will be an awful Friday morning commute. Even if we do stay mostly snow with a southerly track, I wouldn't get carried away with snowfall amounts.

It's really not that much different than 12z.

I posted the data above. in this setup 3° is a huge difference.

I'm telling you guys, unless you're in the northern 1/4 of Ohio, this just isn't our storm.

Ya know there are cleveland posters here, toledo, etc. So just because it isnt "our" storm means nothing. North of I-70 gets snow if it decides to shift south by 30 - 40 miles. As we stand right now, northern 1/4 of the state sees mostly snow. So until it shows them getting nothing, this thread will stay alive.
