October 29/30 Snowstorm Disco - III

Pivot point NW CT through GC?

Yeah it might be, although we have to watch if it sort of redevelops further east as the low goes bonkers. Also, there might be a secondary area of echoes developing near the canal and pivoting nw associated with the low level frontogenesis, If the DS does come in..it might make the stuff near and se of BEDto IJD a little more showery in nature or maybe a brief lull, but I don't think the DS will be a huge issue with continuous height falls.

My guess..strong mesoscale banding associated with 700 low will spread from the south in an arc from west to east. This band will pivot west to nw CT and up through GC and sw NH. However, tremendous frontogenesis from 850-700 should keep some convective like bands going across SNE under the DS at 500mb. It might not even be a complete DS on a line from GHG to UUU and points nw. As 500mb dips its fanny into ACK sound, we should see that GC band move east and possibly intensify as high octane theta-e air gets injected into this system. Tonight will be wild for eastern areas after 06z.

Sounds like fun.

Scott--how much of the qpf do you expect to be wasted due to rain? I just ran skew-t's for mby with NAM and GFS and it has me as a snow start.

28/25 and ovc here now. Seems like we fast forwarded about 5 or 6 weeks wx-wise. :)

Life on the edge (of the good snow bands) here later today. Reminds me of Boxing Day where I got 7 inches and Pete got like 20"+...... But it's nowcasting now and watching radar.

LOL--you beat me to it, though I was going to give him two.

It's going to be a cold halloween for the trick or treaters Monday night.

If you look at the 6z NAM bufkit soundings you can sort of see a dry slot signal at 00z with some drying at about 600mb moving through areas like HFD/TOL and especially HVN/GON. Back toward the northwest in the Litchfield Hills the soundings remain moist with big omega in the SGZ.

Incidentally the NAM brings back big time omega and moisture in the SGZ by 3z as the CCB begins to crash east.

Something to watch particularly in areas that have a hard time accumulating through 00z with boundary layer issues.

Thanks--my quetsion was actually a regional one, not a mby one. It seemed there was a difference between the sounding and the forecast.

Well the higher elevation spots will barely waist any QPF. Down by HFD and up through this area, there will be some mix for a period of time..maybe later aftn? Across BOS..I don't think they sniff a changeover until after 03z, but it could be several hours of RASN being reported. But, several miles inland might be snow. Thinking MQE could be interesting.

SREFs love HubbDave.

Same thing at ORH too around 00z on the NAM (and even GFS) BUFKIT soundings. Monster thump after that though.

Can see weenie dry slot/poor snow growth suicide around 00z before the real fun begins.

Yeah it may make it more convective.showery in nature for a few hours, but I still think there might be another second area closer to the Cape where low level forcing from the 900-800mb area will be huge.

Agreed... that should be rain though. May have a sucker hole for a period of time ORH-HFD while it's ripping in God's Country and Litchfield County

Initially the 7H low sets up rather far west and that offers us our best shot of good snow, but not a great position for snow in SNE in the early going. Then as it bombs off the coast the whole show shifts to NE and overnight I'd assume is when everyone over there can flip to good snow. By then we are west of the best action, but maybe still getting in on some lesser banding.

I predict some toaster baths for sure.

I donot' remember what massive blizzard we had during 2002 and 2004 (I lose track--Will would be horrified by my lack of memory of such things). But I was living in ORH and the sun was peaking thorugh at the onset for aoubt an hour while heavy snow was falling elsewhere across the region. Worst feeling!

Days starting out nice and sunny here it looks like. We'll see how long that lasts.

30.0/27

I think we will do surprisingly well....8-12?

I don't know. It's October, so I guess anything could happen. My backyard thermometer still hasn't given me my first freeze yet. Maybe we made it yesterday morning...If this was January with SST of 35, then I'd be balls to the wall with 12+. That warm ocean worries me though.

We'll rip early Sunday regardless.

Well there was Christmas 2002 ....huge one for us out here.... Another very big Noreaster a few weeks later in January 2003.

Thanks--and congrats, Dave!!!!
