is the thread title a forecast or wishful thinking ?

This was the 60th anniversary of the late August 1986 record cold outbreak. Was the last time MPO went below freezing and NYC reached 50° in August. It was followed by the snowiest winter of the 1980s in Central NJ. Data for August 28, 1986 through August 30, 1986 Click column heading to sort ascending, click again to sort descending.

Yes, the convective mass is impressive w/ very cold cloud tops. but it is amorphous and rapidly pulsing. This indicate lots of shear and/or dry air, which promotes regular severe convection, but it detrimental to TC formation/development. We saw this w/ Bertha when it was on the LA coast and intense mass of convection well S due to strong shear. Look at the loop attached for Ex-Dolly this morning. The convection is "ripping" linearly E to W on a trough line. No circular motion or banding at all. That is not a sign of overall intensification as a TC. Sure, there are gale force winds easily in that severe convection, but that is mesoscale and transitory, not pressure gradient driven on a larger-scale, which what you look for a TC. Basically, it does not fit the requirement of a TC, which is a coherent, closed low-level wind center w/ persistent convection. Yes, you can still have shear and dry air present and have a TC, but this is not the case here b/c synoptic conditions are so unfavroable. It as a strong tropical wave, it can thrive when it comes to intense convection, but lack organization to fit the definition of a TC. Generally you do not want to see rapid blow-ups of convection for TC development/intensification b/c it often pulses down quickly and leaves cooler, low-level outflow soundbites from collapsing convective towers (including downbursts), that radiate away in a divergent pattern, which prevents or weakens any low-level circulation. You see this is often in sheared systems in the form of fine-line line outflow boundaries moving away from the center on VIS. Circular banded convection around a center that has not as cold cloud tops is much better to see on satellite for a TC than what we see for ex-Dolly now.

It makes you wonder prior to the satellite era and modern practices, season that were record quiet, like 1914 (one storm), It is highly likely there were some others just like we have seen this season so far. Short-lived, weak TSs that we simply did not have capability of detecting them well or at all way back. But it does not really impact the climo, at least when you go by ACE. 10 weak, short-lived TSs don't even come close to a single, long-tracked, intense Cabo Verde hurricane for total ACE!

Having an exceptional pattern the other way (i.e. very inactive) is of high value b/c it allows us to see the absolute extremes at the other end and what goes on literally that causes it. Sure, we know very strong El Nino does this to the Atlantic, but not every very strong El Nino is the same and we only have 4 other El Ninos since 1950 on this scale, so odds that when this El Nino is done, we will have witness patterns we have not seen before in the satellite age. Knowing what suppresses TCs I would argue is just as important as to what favors them. And 2024 and 2025 w/o El Nino, we had some previously unseen patterns that ripped the heart out of the peak climo part of the season and resulted in busted over-forecasts. Either it was unusually strong and persistent SALs/TUTTs or the ITCZ displaced unusually far N into the Sahara, and brought to light was the "Atlantic Nina" and its possible role!

Pretty soon you will be as well. The updated USDA climate zones from 2023 has 7b right on Weymouths doorstep.

Why not move to SC?

Clouds have taken over here but the other night with the eclipse it was pretty spectacular. Actually, every clear night is up here. Even with being near “downtown” the sky is incredibly dark and magnificent.

She's doing her best to hang on

Last 30 days, this year is head and shoulders above the rest of the super nino's. Quite an impressive look on the VP 200 charts now.

I've been getting warmer indicators on the Winter than a month ago. Will have to find a site that does SSTA for the whole May-Sept period

This will send you down a rabbit hole
