I think the GFS is trending towards a better setup, it appears the H5 low is trending further southeast. What is happening is that the polar jet stream energy is shearing out to the east a proper burial is needed as there is no amplified ridging occuring downstream, therefore it appears the H5 does it best to get its own low going, problem is that the polar jet stream energy is just too fast and the model biases are not helping us out, instead the fast polar flow is allowing this energy to speed out ahead of the H5 vort max. Still some time, but at least there won't be any phasing problems with this one, it looks purely H5 low related.

This is similar to yesterday's 18z run

Not really. It's a different s/w enitrely I believe and the evolution is all different.

The GFS is displacing the surface low too far to the east in this situation I'm almost sure of it. Bias.

Regardless BINGO we have a solution that delivers meangingful snow now to EMA - well actually two.

Maybe dendrite. I agree with messenger as well. THe GFS does have a progressive bias, however La Ninas are notorious for having a faster polar jet flow so maybe the two are connected. However the GFS normally already carries a progressive bias still too soon for sure. it would be nice to have one last great snowstorm before I leave for Hot Texas.

Not for nothing, but is Windham County really that much less likely to see snow that the rest of CT. I'm not trying to whine or complain, but is there really enough confidence that there will be more or less snow in any part of the state?

its a gamble but if the GFS is right is game on especially in them dar hills

Lol...we need a revote on who the biggest :weenie: is in this thread....I thought it was cpickles now I'm not so sure.

It is essentially the same as the 18z run.

700mb low travels the south coast of CT/MA...nice.

correct...there seems to be a misunderstanding as to what's behind the change. THe surface low probably being artificially displaced to the SE is giving some fits.

As you noted the mid level centers are now sliding along or under the coast which eventually leaves NE winds at many levels near the EMA area...impresive and cold 850mb winds off the water at 54.

I do think the GFS could tuck the SLP a tad closer just looking at the 500 maps. It looks like it escapes a bit too far E at 36h.
