Yea it was interesting to watch the Beaufort region this year not many years have remained intact in this region. If we did not have such an abysmal growth season we could have managed a rare positive uptick within the downtrend. Will be interesting to see when we officially hit the floor and just how the beginning of the season sets up. We did just get a massive warm region showing up over the last couple months in the Atlantic near northern Europe that im sure will play a role in how this year goes for growth.

Nice 90 day loop

Seems reasonable the atmosphere looks really nice coming up and in a good warm pocket. Should at least get 3 days of major hurricane status.

Rough guesstimate depending on just how strong the system gets coming up here but we should get close to about 30 ACE on the year which for the date will be just slightly above average, have 6.6 right now. Will be interesting if we get any follow up storms after this one to end out the month. https://tropical.atmos.colostate.edu/Realtime/index.php?loc=northatlantic

It is the same issue I had with folks thinking there were not 2013/14 style patterns showing up last season but since it did not snow nearly as much last year it was not a match. Not everything is exact and unfortunately you will not change the minds of folks, it is what it is. To redistribute that amount of warming you likely need consistent typhoon recurves and at that strong consistent synoptic activity coming off China/ Koreas/ Japan. Tropical activity has been very sluggish in the WPAC for some time and when we do have activity the main track has been almost due west at low latitudes with the stronger systems (maybe 1 or 2 systems in a season actually recurving) or 'home grown' systems (close to land formation). Honestly let's just see how it all plays out.

I mean there is a lot of warmth with depth that has yet to be mixed. We do need much more in the way of tropical/ synoptic activity to really overhaul this region which will take time. There is definitely a noticeable shift trying to take place but the pattern is still very much entrenched across the region. As much as I want it to change it still needs time to make these changes.

Pick your poison a week plus out you either get the threat of TC landfall and warmth over much of the East or you get cool and storms get scooped up out to sea.

I still find it very weird that we can use new baselines and the anomalies that are associated with them as facts (especially temps) but yet we use this chart above as fact taking out that baseline increase... https://psl.noaa.gov/map/clim/sst.anom.anim.week.html https://coralreefwatch.noaa.gov/data_current/5km/v3.1_op/animation/gif/ssta_animation_30day_large.gif

It is trying we need to continue to see the onslaught of tropical/ synoptic activity holding the ridging pattern out there at bay. It more so looks at this point the waters are just being displaced yet again across the region like we saw last year. One noticeable feature has been the warming of waters around the Bering Sea versus the last couple of years where we saw a large cool pool which would thwart any effort into ridging staying in the EPAC. Still got a long ways to go but good signs none the less. Kind of still liking this idea of a 500mb pattern as we get into winter. It allows some relaxing of the horrible winter pattern we have had over the last at least 5 years across the Mid Atlantic.

Legitimately if this had not started out as one of the lowest winter time volumes recorded this would have been an amazing retention year. The pattern was damn near perfect to lock in ice and cooler temps. The biggest help has been the lack of Canadian warmth up to the Archipelago. I don't even think the NW passage will open this year given we have about 3-4 weeks left of melt, unless this pattern completely flips on us.

Should have saved this until tomorrow but whatever here is all of June/July and the 1st of August.

To me at least this is telling me we are slowly cooling off the WPAC with no real discernable changes in the central and EPAC with SST. Baby steps.

Yea TAO has the cool pool further west and a smidge cooler. Overall though placement of warm anomalies isn't too far off from each other. This is the second weakening of trades that has occurred over the summer last was around early June so I'm curious if we start to see the westerlies that have been stuck around 90E start to wane in any shape and develop further east toward the maritime continent (120-150E). We still keep getting random bouts of a Nino like response even with the -PDO where it is and the weak cool/ neutral SST profile.

Totally forgot DCA _ NYC _ BOS ___ ORD _ ATL _ IAH ___ DEN _ PHX _ SEA +1 +.8 +1 +.9 +.6 +.5 +1.5 +1.8 +1.6

Amazing no one likes to comment on thoughts and actually have a conversation in this thread it is either arguments or silence. i still see why raindance has essentially stopped posting.

Lol im not sure I understand this idea of his that the Caribbean can not foster a storm until it hits global mean average. Beryl came through early in the season (early July) but the next storm didn't form in the Caribbean (west) until Helene which was in the 3rd week of September. The SSTs were on fire last year but that did not dictate if the Caribbean would produce a storm. If the environment leading into the Caribbean was a little less hostile we would see a storm be able to do just as Beryl did or Helene. Remove the shear currently in place, which seems likely in the coming days, and a decent system tries to roll through it will produce. I feel like we heard this last year that ACE could not hit above average too. Edit: Why does it also have to go through the Caribbean to be an active season.

Have a feeling we may start to finally relax a bit on this -PDO pattern. Tropical storm and typhoon activity on the rise in the WPAC in fact the one ongoing system Krosa (I believe) looks to attain at least the equivalent of a cat 2-3 going over some of the warmest water anomalies east of Japan before recurving and going extra tropical creating a large wind field for this time of year as it nears the Aleutians. We will have to see if this continues because a one and done will not do the trick. I do not expect the PDO to completely flatline from this but we are starting to see signs of a shakeup in the continual ridge setup that has been around east of Japan. The cold tongue off Baja and California is also starting to neutral out if not go slightly above average as we go into August. Forcing also weakening up a bit around the Maritime continent and pushing closer to the dateline more often giving the MJO a 6-7-8 look. You can see the relaxing of +VP over the Atlantic coming up. Might even have a sneaky little system in the Atlantic to be on the lookout for as we head into August. While the pattern is not conducive right now it is also changing with time so we need to watch for any type of systems that make it to the eastern Caribbean islands in the next week.

To be fair it is not perfect but got the idea. Little rough for the mid atlantic/ ohio valley pattern

Yea it is reasonable to think we break the mode every once in awhile like we did last year. I have been meaning to see what inevitably breaks the -PDO down from past events regardless of value. What trigger atmospherically kicks it down and switches it over because as we have seen ENSO doesn't quite do the trick. Im more so excited for the break from the 70+ dew points coming up on tuesday.

If we get any potential of Typhoon action and especially recurving Typhoon action it will fail.

Lol I just saw that. Given early indications of simply just looking at configurations I don't think this is a bad take for potentially happening this winter.

Shoot the messenger or don't (please don't) but there are definitely some similarities SST wise to 2013 and 2017 to this year so far. Yes I know 2013 is not happening same ol same ol but one can still analyze the aspects of how similar they are still somehow. You could even try to throw in 2021 if the Nina can actually try to be something SST wise. This year we have just overall bumped the warmer mid latitudes compared to those years.

Yes it something very similar to this last year I believe we may have peaked a bit earlier this year than we did last year but will see how the 500mb sets up over the next few weeks to give clues. Some models want to slowly erode the 500mb high setup versus others just obliterating it (frickin GFS). We should take a run at the lowest monthly value but probably fall short depending on how quickly things level out. It has been raining quite a bit of late for that lol

Hopefully we can get some heat dome MCS events before it shifts.

I get what you are saying but locking it regionally (Midwest/ Ohio Valley) like you posted is not factual. It has been a warm summer I would actually say last summer was probably warmer than this year has been for the CONUS but we won't know until late August. Humidity/ dew point wise nothing really has been that different from prior years across the CONUS we are still hitting our low to even mid 70s consistently around here in the mid atlantic like we have over numerous years. The corn crop is still causing evapotranspiration as it has, hopefully this dies off as we move into a less HFCS type of lifestyle.
