Snippet from the WPC EPD.

EXTENDED FORECAST DISCUSSION

NWS WEATHER PREDICTION CENTER COLLEGE PARK MD 1141 AM EDT SUN MAR 09 2014

THE MODELS HAVE FINALLY CONVERGED ON THE TRACK OF THE COMPLEX WAVE CROSSING THE EAST EARLY IN THE PERIOD, WITH ITS MOST MARKED SENSIBLE WEATHER THREAT BEING A STRIPE OF HEAVY SNOW FROM NORTHERN ILLINOIS AND INDIANA THROUGH THE INTERIOR NORTHEAST.

It'll be interesting to see how this unfolds. I tend to think today's 12z runs have maxed out the NW potential. But who knows?

 

 

i haven't been following close but seems like it could go either way. 

 

12z GEFS support the OP nicely...a few even more generous further north

For me the trough axis is too far east. We're going to need the vort dropping out of Manitoba to dig due south to get the trough to tilt negaltive early enough so that the sfc low can wrap up and cut well north of the OH river. That's just too much effort to get the whole northern stream to buckle like that, especially with that kicker coming onto the west coast, which should tend to keep the flow progressive.

 

That's my $0.02.

I think it would be hilarious if a more phased solution won out like the ggem from 2 days ago instead of the storm cancel the 0z models showed last night lol.

 

You mean that solution where it had the 987mb low over Detroit and it showed a good hit for you?

 

No, that wouldn't be very funny at all.

On the positive side, it's north of yesterday's 12z run.

At least it appears we have two solutions camps now.

GGEM/EURO/UKMET vs. NAM/GFS.

America vs. World... We've seen this before.

Edit: SREF looks to mostly be in the foreign camp though
