March 13th ... west Atlantic bombogenesis type low clipping SE New England, more certain ...may be expanding inland

[78Blizzard]

Jim Cantore just said that "not only is this thing going to bomb, it's probably going to bomb twice".  Whatever that means...

[ORH_wxman]

Hard to tell on the crappy black and white maps, but rgem looks a bit better at 18z too. 

[WeatherWilly]

Still some disagreement with the Rhode Island tv mets. WPRI sticking with 6-12 for much of rhode island which seems low to me at this point. ABC6 more bullish 10-16. NBC10 splitting the difference.

Bold:  BTV stays with a Winter Weather Advisory for me due to the long duration to get to the totals.  WWA with potential for 12+.  OK that's interesting.

LOL I have to post this because 1) its hilarious and 2) our boy Mitch @BerkshireWx, wtf will he do with another 55 incher

The Berkshires and SVT are going to get a sick upslope event too... they'll get it before we do up here based on the cyclonic flow and position of the mid-level lows.  They'll be getting crushed on Wednesday afternoon and evening while its much lighter up here due to relaxed wind flow.  Then it should move north up the spine as the mid-level lows drift off to the northeast and the flow increases up here.

Synoptics and meso-scale features are going to make this a fascinating storm for a lot of places. 

[Henry's Weather]

Cheers to tomorrow! Best of luck to everybody.

[ineedsnow]

On tropical tidbits looks like it stalls between hr 13 and 19

[weathafella]

I believe Harv is going 10-15 way west and 15-20 right along the coast from cape Ann to the canal.  Not sure if Logan is in the 15-20 but he’s going all in.

[JC-CT]

ryan broadbrushed the state 6-12, i think it's a decent move

[CoastalWx]

Gets the CCB into near Boston now. 

[CoastalWx]

Some snow will be lost to wetness or a brief mix at the coast so take the numbers down a few at the coast and lower spots.

Def can't fly out tonight to DTW, nor can I drive there. So I'll either have to postpone it for Thurs or try my luck on Wed.

This is super helpful though, thanks a ton!

Oddly enough they haven't canceled the last BOS-DTW tomorrow.

Good luck with all … that.

That won't fly. They just haven't canceled it yet.

Maybe a late train to NYC if they're running tomorrow, and a flight to DTW from there? 

[HIPPYVALLEY]

Just got the robocall cancelling school in Greenfield.  They rarely cancel this early, superintendent must be following the NAM.

[CoastalWx]

Yeah coastal and low spots on SNE.

[78Blizzard]

RGEM improved from 12z, but still appears weaker than other guidance.
