700mb fronto band starting to take shape. Looking at radar now, it might be curling a bit SW through Vermont back towards the capital region.

Easily 1”/hr in this banding

2.5”

Similar conditions to your west, radar looks great with additional banding pivoting in from the south.

Probably around 3” here

Sunapee gonna get smoked 

Yep, 32.0 here and seems to be accumulating relatively unimpeded. Closely watching that band lifting north from Keene

3k NAM has some convective issues with the slp shunting a bit south. Tossed

Fake cold indeed. 36.7 farther north in Sunapee 

Will be spending the duration of this storm at 1100’ near Sunapee NH, we could rip pretty good here.

Yes sir.  Let’s focus on the next two weeks for the time being…and let the long range guys worry about what comes after.  But I agree, it’s a promising look at the moment.

Loving the contrast between “let’s focus on the next two weeks” and “this pattern might remain through next winter” on back to back posts.

Rafael is rapidly unraveling. The only November major hurricane in the Gulf (besides Kate). One for the record books

Impressive performance by Rafael this evening. Major at 10pm EST I bet.

This must be the most menacing looking storm in terms of location to not even have a single TS watch or warning issued. No intermediate advisories either!

unlikely 

I am interested to know why this may be a mirage, tropical forcings perhaps?

At first glance the high-latitude dynamics seem like they would be sufficient to temporarily tighten up the lambda on the continental rossby waveguide 

A bit of a trend emerging over the last day for mid-month on the GEFS. The EPS has shown this trough anomaly on the eastern half of the country for a little while as well.

Refreshing to see long range changes, if still very far out. This potential break in the ridge will likely transient in nature as this feature propogates quickly across the CONUS.

Listen, I don’t pretend to know how much snow we’re gonna get.  All I know is that it will snow here in SNE this winter.  
 

Long range forecasting is a crapshoot at best…just look at what happened with the hurricane season forecast, it was a complete bust.  So I mean I put very little faith into anything that is 4-6 weeks out at this moment.  And for the heart of the winter we are 2.5-3 months out…so unless somebody has a crystal ball, I’m not buying into anything on 11/4.   But that’s just me. If you guys want to worry yourselves to death, that’s up to you. 

Seen this hurricane season take a few times, the NOAA forecast has verified across named storms, total hurricanes and major hurricanes.

Uh oh. It's tracking right toward Texas.

I am fervently sorry about all the times I bragged about 'no way hurricanes hit mby'. I know damn well we could get literally demolished by a really bad hurricane. Look what happened in Asheville NC, 33 inch rains and 130 mph wind gusts. THAT FAR FROM THE OCEAN!

It has been really good knowing you all.

Just in case, you never know. I'm not safe either. No place to hide this season.

Extremely unlikely makes landfall in Texas. The only scenario where this storm gets close to Texas is if the storm gets ripped to shreds by shear and the LLC decouples. Cold water on approach to land is also in place. Breathe in, breathe out

Hurricane Ida (2009) repeat without the secondary peak intensity IMO

The good news is that lack of solar strength, mixing, etc won’t maximize the temperatures like can be done at other times of year with this H5 pattern.

Low level cold undercutting the mid-level warmth and CAD from the Maritimes can lead to cooler surface temps than the long wave pattern suggests.

Overall though, the EPS/Euro Ensemble has been 50-members of upper level ridging in the means.  Pretty stable/steady pattern.

Monday…

10+ days from now…

15 days from now…

 

The hemispheric rossby wave evolution to maintain this pattern is quite remarkable. Happy to get this out of the way in November, myself and many others would be quite angsty if this weirdly persistent pattern showed up in January.

The consistent deposit of vorticity back into the western trough really drives the persistence of our downstream ridge.  Very impressive how the wave structure strikes the perfect balance between trough attenuation on the low-end of vort advection, and wave breaking for high-end advection. Instead we get stasis. An impressive traffic jam of blocking downstream also slows propagation just in time for vorticity to go reinforce the pattern along the wave axes.

Long story short, this ridge doesn’t want to go easy. Again, hoping for a trigger from the W-Pac to reshuffle the deck.

Until the index significantly change the GFS operational likely to keep flopping right back to warm looks …obliterating those.  

Probably gonna get periodic inserts of cold just good for upslope and maybe snowmaking but you’re gonna get warm blasted two or three days later and it won’t make it worth it

If the index change then fine otherwise check back in after Thanksgiving giggity

Exactly, we are pretty locked into eastern ridging for the foreseeable future. Sure, we can get a few cool shots in from various sources here or there, but we need wholesale teleconnection changes for real progress away from the hostile rossby wave configuration we have. Subseasonal indicators are pretty iron-clad right now across the upper latitudes, and tropical forcings are not helping.

A nicely timed recurving typhoon could be the trigger for changes sooner than modeled. Until that happens, or other forcings flip key indices, semi-consistent bursts of winter will be confined to the ADK High Peaks region, the Green Mountain spine, the Whites through Pittsburg, and the Mahoosucs/Aroostock county

I would caution against getting excited about the long range deterministic models showing some “winter-like” storm activity. Ensembles are still very hostile with the ridging through mid month, maybe we can squeeze out a cool shot in about 10 days on the backside of the troughing anomaly over the Maritimes.

I would watch for some cutters after mid month with hints of a -PNA showing up. Honestly that’s progress toward a cool season pattern, considering where we are starting this month.

The storm nearing the Azores is now Invest 96L. This could become Patty soon.

Organization is there, convection remains quite shallow. I think they could have upgraded at 5pm, but NHC might be looking for more robust convection before doing so.

Really a pretty awful look for the next few weeks for colder temps. Yuck

Hard to tell with lack of quality radar, but looks like a direct strike on Grand Turk

Current motion seems likely to have the tiny core miss Providenciales, which is fortunate. Grand Turk may not be so lucky

Latest dropsonde shows Oscar on the cusp of category 2. No word on if this is rain affected yet, but Hazelton is giving credence to this result

NHC needs to upgrade to hurricane and issue hurricane warnings immediately. It would be negligence if they don’t 

3nm diameter for the eye… take that Milton!

NHC special update: 70mph, 991mb

Several VHTs rotating around the tiny core on IR sat… wild turn of events this morning 

Really makes you wonder what recon would have gotten if they flew into Eta at it's peak. Somehow T numbers were higher than Milton's for a brief period there

Code Red, might be time to fire up a thread on this.

Nasty looking PRE setup. Regardless of how strong this system gets, this is a really concerning situation for an already flooded FL Gulf Coast. Good to see the NHC starting to push out some messaging for coastal residents to prepare.
