Not a bad looking line

Slight risk introduced for tomorrow up north!

Probably a good call. It's a fairly strong HP and pretty big

I think the WAR ridge will be key. Obviously things can change as we move through the cool season but this look in the Atlantic right now isn't very comforting. Models have also really struggled with Atlantic ridging the past few years and I think moreso this summer and that could be a culprit of the lack of cross-country flights. I do recall though some research into +SSTA's around Greenland correlating to a greater chance for a -NAO but of course there are other factors to consider. I'm curious as to whether the smoke from the wildfires in the West will have an influence on the stratosphere? I saw some rumblings about that but I have no knowledge in this aspect. It also looks like we could be heading towards a "basin wide" or "central Pacific" (or whatever you want to call it) La Nina.

Hopefully it will be more exciting than last winter. But I'm real curious about this winter. If the theme of establishing a ridge in the West holds at least through a good part of winter I would think that would bode well for us...but if the SE ridge becomes established we could get an omega like setup so then it becomes a question of where the trough axis is positioned. I really wish I had more time (and knowledge) to explore long-range forecasting. I used to be super, super into it but time is just not there...and my methods for "research" suck and are too time consuming lol.

Hopefully we'll get coastal storms to track but who knows...if this becomes a Nina with a monster SE ridge the storm track may be across MI lol

the Euro has really struggled this summer...especially in the tropical department (actually has been kinda brutal). but I think all models have struggled this summer. I seriously wonder if decline of flights due to COVID is playing a role and a rather significant role. I'm just curious though if the GFS cold bias has been fixed or muted a bit. Thankfully they have gotten some rain in WA/OR but CA...I just have no words. Looks like another hot stretch coming too with 80's and 90's across interior CA...even OAK could get into the 80's again.

The GFS would certainly argue that but the euro argues quite differently. Regardless, it does appear as if we'll see somewhat of a gradient pattern setup so that is certainly possible up north. Looks like a scenario where we sneak in some brief cold shots (at least into NNE). I just can't believe there is another sizable ridge building into the West lol...they can't catch a break.

Monday good drop some decent rain into southwestern CT. Probably going to be a huge cut-off between the heavier rain and virtually nothing with the HP to the north. Monday looks pretty chilly too and breezy

Actually looks like we'll see two different lines (similar to Wednesday as well) but only one line will be the main producer. The main producing line will drop into upstate NY and northern VT/NH. The second line may fire (still in upstate NY) just a bit further south (towards the capital region again?)...this may not traverse as far of a distance but may produce a small, but very concentrated area of wind damage.

Yeah would be nice to see something. One thing I don't particularly like though is it seems that timing of the s/w trough has slowed a bit. The other day there was perfect timing on just about all pieces/ingredients. There may be some displacement here...but still may look good for upstate NY and extreme northern New England.

ahhh great point...I didn't even consider about low-dewpoint derecho. But I also do believe the distance criteria is probably standard throughout...although given how this went to the coast I would say this met criteria.

looks like there was a confirmed tornado in NY yesterday

Forecast models are in agreement in very steep mid-level lapse rates associated with a plume of EML air will traverse the region on Saturday. During the afternoon yet another vigorous shortwave trough is set to eject into northern New England. This will be associated with yet another potent mid-level and low-level jet with a max passing right through northern/central New England. At the surface, temperatures should push well into the 60's to lower 70's across northern New England with mid-to-upper 70's across southern New England. There are some uncertainties regarding moisture return, however, dewpoints may push into the 50's or even lower 60's. This, combined with the very steep mid-level lapse rates should contribute to more than enough CAPE to fuel convective development. Strong heating should also promote very steep low-level lapse rates. Given the above, the potential exists on Saturday for one or multiple squall lines to propagate through NY and northern/central New England. Given the signals for widespread damaging winds, a serial derecho is possible. There is also the potential for brief tornadoes with any initial discrete cells or embedded within the squall line.

I am a bit boggled though. I mean looking at mesoanalysis in the morning it was advertising as much as 150+ 3km CAPE advancing ahead of the front with 2-6km lapse rates nearing 8 C/KM and DCAPE values were 400-500 J...who knows...maybe they just focus on their HREF products and whatever probs they spit out lol
