Potential widespread snow event for Wednesday Night through Thursday.

Yeah I think it's close to the 12z euro now. I think you had to expect this because the NAM was so far south. It's actually a nice hit for you.

Thats what I figured based on todays breakdown of the euro. I'd expect to see the GFS dribble SE.

Hey, Plympton Public closed Weds...

Messenger home with the kids if Plymouth cancels too?

Not enough beer in the world.

I wouldn't say they've done a great job; their forecast discussions are interesting but sometimes they lack a bit of common sense.

In the midst of the Boxing Day storm, they raised my forecast to 23" snow when it was clear we were in major subsidence and struggling to accumulate. Anyone looking at radar could see that NJ was going to get way more than the 23" forecast and Westchester way less.

They were very conservative in the 1/27 storm and originally didn't buy a huge hit.

They made a mistake in the 3/21 storm calling for rain when many in the 'burbs saw 1-3".

This will be their biggest mistake of the season, I think.

The point-and-click grid is obviously broad brushed and fails to account for mesoscale nuances such as CSI banding, thus it's a rather poor indicator of the overall skill level of an office.

Like I said ..the NAM has the fight over my house all day tomorrow ...until finally the inverted trof or deformation (whatever it is) sets up overnight tomorrow night.... So I'll report in on how well it's doing. :snowman:

Its going to be a hell of a battle trying to hold off this system from going north. The confluence is very strong though and will put up a good fight.

I don't know why people are obsessed with point and clicks. They should look at the ZFP.

The ZFP are generally buried in an obscure link on most NWS sites so probably almost nobody even looks at them anymore. It seems clear they wish to promote their point forecast product.

I like the ZFP much better and has the human touch of editing. Point and clicks sometimes look goofy with the wording.

Ya think

A chance of rain and snow before 7pm, a slight chance of snow between 7pm and 2am , slight chance of snow and sleet and rain between 2am and 4am, then a slight chance of rain after 4am.

Yeah it sounds like a bunch of nonsense right. What's really funny is when some radio stations (that still use the NWS free product) read them on air.

RGEM is playing some games.

RGEM appears to be a little south. 5mm dips just south of the MA/NH border and the 10mm line is further south cutting from the MA/CT border across RI into SE MA but south of Boston. It was north of that for the same 12hs on the other run.

Not a big adjustment at all ,but a nudge south.

Didn't even need the follow up....whenever you leave anything open ended, nothing I'd like to hear will follow. :lol:

ray it's absolutely miniscule.....sure if we overlay the maps...but we're talking 24-36 hours and reallly not a big difference at all.

GFS is probably moving south some this run, so long as we have no big outliers one way or the other all the things Will/Scott have been talking about come into play/focus Wednesday.

I mean these are really pretty small changes towards consensus on the NAM/RGEM. Maybe mean is a better word.

If the confluence isn't so overbearing, then we could definitely see a very nice ML fronto band north of where models like to paint the qpf. You just don't want the confluence too overbearing as to shear everything out. But if we can get a stronger WAA push into the confluence, that will only mean more intense ML frontogenesis.

You go from nothing to 1/2SM snow in about 15 miles over in MI right now. I wouldn't be shocked if it does that in parts of this area, later tomorrow. Like you said..hopefully it's not too powerful, because the ULL can really enhance the nrn edge.
