Ocean Effect Snow Showers for the Cape and Islands Jan 13-15th 2015

Yeah great snow growth in that band.  Multiple bands over east of the first band is not producing much here in Harwich, MA, we have partly sunny skies.

Harwich, MA of Cape Cod, MA is not a good place for OES on NNE wind. does better with NNW flow

[jamesnichols89]

True, true Phil, think we can get in on some inverted trough snows on Thursday or real storm synoptic scale snowfall?

[SouthCoastMA]

Sandwich is usually a good spot for these

[jamesnichols89]

Yeah Sandwich and Barnstable, MA are good places.

[jamesnichols89]

We are getting a pretty heavy snow shower right now, not heavy squall per se, but a heavy snow shower.

[CoastalWx]

I bet someone near sandwich had over an inch now.

I'm getting crushed right now, like Tolland crushed.  Nice to see it snow for a change!

That's a nice band. This should be on and off for a couple of days. It wouldn't shock me for someone to get more than a few inches if bands align. Today is OES, but eventually winds shift NE and it's more of a cstl front convergence. However, inversion heights will lower so that limits instability, but someone may get lucky. I even have a shot as the cstl front moves west maybe tomorrow night, although this looks like more for typical OES spots in pym county.

[CarverWX]

Do you guys think we see anything here?

[CoastalWx]

Do you guys think we see anything here?

Maybe tomorrow? I'm not sure this will make it much past the canal by 5 miles or so. I suppose you could see some -SHSN though.

[ORH_wxman]

Pretty good stuff right now in some of those bands

 

 

[CoastalWx]

Winds aloft are allowing for that west propagation too.

[HoarfrostHubb]

James ftw on this one.  Well done.

[jamesnichols89]

Thanks, I'm getting some heavy snow right now, ok maybe not greens on radar, but its cloudy completely and its coming down nicely, nice snow growth as well, big flakes.

[codfishsnowman]

can oes really bury like lake effect?

[SR Airglow]

Nice James, enjoy it!

 

A good amount of the short range hi res guidance has some lighter stuff making it decently far back west, the NAM/RGEM/SREFS all have 0.5" or more from about BOS SE overnight tomorrow night. Worth keeping an eye on if folks are looking to whiten the ground.

[CoastalWx]

can oes really bury like lake effect?

Not comparable, but it's helped enhance some totals for sure. Jan 2 of last year. Classic ones like feb '94 which helped dump near 30" just south of me, even December 20, 2008 helped enhance snow in this area. There's a lot of events where it more or less enhances by a few inches.

[ORH_wxman]

can oes really bury like lake effect?

 

No, the lack of land convergence hurts the ability for OES to line up in a large very organized band. So we typically see multiple less intense bands like we see on radar right now.

 

That said, you can still get warning criteria from OES, though it is pretty rare. I recall a couple events giving around 6-8" in spots over the years.

[jamesnichols89]

Yeah Will, I remember one event had 6" and cancelled school that day, this was back in grade school, so about 13-15 years ago, in the 90s.  Anyways, bands are intensifying over the Bay, but over near me its weakened.  Sun is back out with a dusting of snow on the ground.

[jamesnichols89]

New band developing over Eastham, MA, that should give me another period of snow as the bands progress westward before weakening later this morning into early afternoon.

[Damage In Tolland]

Noyes said CC could actually rain tomorrow and Thursday

[Clinch Leatherwood]

Nice heavy bands as they roll through.  Impressed...windy as a mother too!

 

Pretty good stuff right now in some of those bands

 

 

 

 

Great bands - the snow is not well aligned with those bands however.  IE, the snow extends a bit west of the bands on radar and the sun is out on the eastern side of the bands.  Definitely some fun wind stuff going on with altitude.

[CoastalWx]

Temps may get into lower 30s there, esp Thursday.

[CarverWX]

Flurries flying around here

[jamesnichols89]

Scott, just lower 30s?

[Tropopause_Fold]

nice band forming over the western part of the bay...Sandwich / W. Barnstable probably going to get a good squall in the next hour. 

[jamesnichols89]

Phil how are you doing with the snowfall?  I got a dusting here.

yeah and also almost never going to have the unidirectional flow to 700 mb like they see out there...and the cold is almost always deeper out that way so the inversion heights are through the roof. 

 

they tend to do best when there's some sort of synoptic scale feature moving through to give that little extra kick. we got clocked with one when i was in high school - but i can't remember the date. 

[CoastalWx]

Pretty nice looking alignment too considering daytime can mess around with them a bit. Suck that heat right out....lol.
