Lastly, the addition of tropical remnants does not help our cause, as that will likely assist a bit in further geopotential height rises via diabatic heat release. While we will still see a storm, it will be a fast moving and likely weak system with a lack of any substantial and sustainable cold air for our region, as we will be warm-sectored. though unsettled conditions will persist for a few days as the multiple spokes of energy rotate through the broad-based, yet lifting trough.

Good info. I love winter threats, but when leaves are still on the trees (a few Halloweens ago), we get serious power outages and lots of trees down.

power impacts will be mini.sized without snow Def but remember how wet it still is and trees won't need a lot to uproot. Branches breaking wouldn't be the biggest issue unless we had the snow.

There will be a coastal gale with some tidal flooding, but otherwise just rain.

so not really a nor Easter so u disagree with frank going storm mode? I mean we have had plenty of plain rain events but frank hasn't hoisted storm mode.

Yawn okay good to know. Frank why the storm mode seems there's consensus this is go be nothing by many members.

I guess there were some rogue storms sparsely scattered today one prompted a tornado warning on the ri mass border.

No, it’ll be a Nor’easter, and that’s his call haha this peanut gallery doesn’t comment on such things, but given the expected precipitation amounts, the wind, and the type of system/time of year, I don’t see why he shouldn’t have. I mean, if we were dealing with the same system with colder air we’d certainly be in storm mode, so while I don’t really pay attention to that stuff, I appreciate the consistency haha

I think all rb is saying is this is not a winter storm. I don’t think there is “consensus” that this is “nothing”. It is heavy rain and gusty winds with coastal flooding. For those who only get fired up by snow, that may be nothing, but in terms of weather, nor’easters are one of our most dynamic weather events in this part of the country - snow or not.

sorry I was not taking Frank's storm mode lightly...I had tongue in cheek comment on more rain...noreeasters are nothing to sneeze at..I remember the day after we moved into this house we had a really strong one...

Yikes, possible tornados and funnel clouds in Massachusetts today, funny how New England, NYS have been seeing severe weather lately....

I was fully expecting a pissing and moaning comment seeing syo posted lol, that this is not gonna be snow, jk. I know nothing about fishing how would a noreaster help fall fishing? And man fall is like 2/3 over better get it in quick lol

I see the wind threat is more from the pressure gradient between the LP and high above it not so much the storm itself, It seems to be modeled weaker and weaker each run now not even getting out of the 990s or even low 1000's. Some ensembles still show sub 970 and even lower but the majority are agreed on intensity.

Scott the euro and gfs are still showing all the main precip to the east do you still think this is incorrect? And what is causing that on the models. 2 to 3 inches isn't much considering duration. Now if this were snow boy would it b for the records imagine 10 to 20 inches factoring in slush in October.

I will certainly conceded that this no longer excites me for much frozen stuff.  In fairness to myself my comments the other day had several different 500mb solns that were more consolidated with some of the 500mb vorticity lending to the possibility of a "self made" colder soln scenario, and I have not been following the evolution along all that closely at all.  The self generated cold air scenario just doesn't appear to be happening. There are a few things about this storm.  1) which Ray has already alluded to and that is the source region is too warm; modified Pacific, deep south, and sub tropics.  Very hard to over come these source regions this time of year.  You need a very potent phased system to generate/draw in enough cold air from the north.



2) it appears 500mb closes off over the Ohio valley and passes N and NW of the region.  Our area usually wants to have a 500mb closed low pass more to our south to get into the colder sector.  




3) Jon to answer your question in part there is a ton of vorticity at 500mb none of which is definitively phased or consolidated associated with the mean 500mb trough.  However; looking at the vorticity maps at 850mb there is a ton of strong strung out vorticity there too.  My guess is that if these maps are correct on the euro that because the 500mb vorticity isn't a single phased consolidated system that this energy at 850mb is enhancing lift in these areas complimented by a strong LLjet set up along a frontal boundary, so more intense mesoscale vertical lifting rainfall, rather than a tightly wound "classic" Nor' Easter is occurring and why the precip shield looks the way it does on the Euro.  Don't get me wrong there is plenty energy aloft such that a strong storm with strong winds and heavy rain will happen, but it isn't the typical "classic" Winter Nor' Easter with a strong phased 500mb system.

There could be wrap around rain Sunday morning. It is likely to be overcast most of the day. Then Monday a clipper-like system, very weak, will pass by bringing us more rain. Less than 1 inch.

I hate all this rain I'm a yard sale picker and its my favorite thing to do on Saturdays when it rains not only do I miss out on the fun but I don't make money. And yes I often actually make more money reselling stuff than I do at my regular job. I just realized this is banter. I'm ill so if you guys wanna move it please do I'm not retype it. Will there be enough instability to have at least some thunderstorms with the nor Easter? 30 to 50mph winds are winds that start to impress me but not overly exciting. I can't explain why wind interests me so muxh. Snow is easier to understand. I will say one thing after seeing crazy storm chasers in Michael and 150 plus mph gusts I never want to be in that that's way to high.
