GFS is toasty. Prob a bunch of rain here before a flip to hellacious thump for a few hours. 

All about the flip. After the 00z model suite I was expecting it around noon here. A flip around that time gives us a shot at double digits.

Of course.....this is going to be one of those systems where when you measure "by the book" you got 10" but when you shovel at the end it looks like 3"

I need to see it in Bufkit before I'm entirely certain, but at 15z Sat it looks awfully close to freezing throughout the column despite being 37 at the surface. It looks like the lowest 500 m or so are above freezing for sure (~1600 ft) so that's pretty close to all snow that early in the day.

Starts off with +1C at H95 at ASH midday tomorrow, but by afternoon that wetbulb 0C is below that level despite throwing out a 35° at 2m (976mb).

You trace that cold side of the innermost closed contour. That's a tasty track for a lot of people on this board.

I keep watching the H5-H7 track (they are almost the same since this goes nuts so fast)....having those go over the Cape is premium for a good chunk of interior SNE and I think having them exiting out into the gulf of maine signals at least a few hours nearer to the coast around or just north of BOS.

Yea, GFS will be too warm...I will trade the more eastern tracks for more development. Dynamics will be more valuable than that few miles of longitude.

I booked a room at Henniker Motel. I’d rather have elevation. Getting a few things done and heading out. Excited. Hope I can score a foot plus out of this.

Canadian looks like rain? 

It has... and if this warmer solution verifies One could point out we aren’t exactly in an NAO negative right now... 

the Canadian has been most consistent of em all the whole time.... I feel like, predicting a warmer soltn

 

15z RAP looking great for CT but I don’t trust it for 30 hours out

It's pretty warm around H85 through like 18z-19z, though.

Ashburnham has a couple of hundred feet of el over me       They do amazingly well.    

Honestly I think the best area ends up east of us.  It almost always trends east versus west as we get closer in. I can only thing of a couple times where it went the other way.

Fall back on conceptual models and ignore the 2 m temp noise. Between 18 and 21z those winds go from NE to N in Essex Co and that should stop any warming potential for the rest of the event.

Yep. Still probably a sick thump GFS verbatim. Any more NW tics though and we're probably on the outside looking in enjoying 1-2'' of slop at the end.
