All Activity

Looking at the sat pics this morning there are lots of fires burning in Southern Ontario. The thick smoke plume is moving into our area. How much is this going to affect the severe storms later for NNE? Also the MCS is creating a lot of cloud cover especially this morning. So we are not getting much insolation. Maybe this will reduce convection later?

I knew what you meant ... I was just adding that physics requires that a well mixed column has to obey the adiabat temperature distribution in general. If it is 2 am , and the 850 is 20C, and it is well mixed, it's in the 90s at the sfc. Whether or not the atmosphere is can be well mixed at 2 am or not is another matter LOL. That's why nearing evening on hot days, if one is excruciatingly nerdy enough like me... they might notice the light west wind that had steadily rusted leafs all afternoon suddenly goes calm; it's because the surface - albeit still hotter'n Hades - has slipped below the adiabat. That adiabatic temperature might be 98, butt's in the low 90s...etc

Exactly what I was getting at the past couple of days...pattern resembles La Nina right now. In the past, this would imply a flaw in the development of El Nino, whether it be weak and/or poorly coupled. However, that is not necessarily the case in our modern climate. Powerful, well coupled warm ENSO and and cold phase Pacific are no longer mutually exclusive due to the degree of heat that is not stored in the Pacific basin. I think Adam perceived this as me saying that El Nino isn't as well developed as most think, but that is not at all the case. It's just facing more prominent competition from around the hemisphere relative to it's predecessors.

Wednesday the smoke could reach all the way to the surface in some areas- that combined with the very hot temps could make it the most dangerous day of the season so far..........

Some hi res show an iso storm around here tomorrow. Probably ends up south though.

some low end thunder chances entering the mix, probably a miss west/south but will be nice to see some towers again

.27 overnight. Storm total of 3.54

This is another example of how the models past 15 days really don’t have much skill other than general forecasts for ENSO SST plumes. Notice the locations of the ridges and troughs verifying are reversed from the seasonal forecast issued in May. Most of the time during the 2020s summers the long range models miss the strong -PDO and +AMO influence of these greatly expanded subtropical or mid-latitude ridges. July forecast issued in May Verification so far

Most everyone cashed in, but still some losers and winners.

9z HRRR for JACK Probably would like to see a bit more curvature in the 0-1km layer for true concern for a strong tornado, but those sfc winds end up more 200° you're going to ramp that up quickly. But this is a significant amount of CAPE up to the EL and that mlvl shear. You get a mature supercell moving into this environment and you're probably looking at a spaceship structure. Pretty good inflow into the environment too.

Methuen borders Lawrence I can always smell smoke where I live in Methuen....

Definitely a lack of +U out there in the N pac. Wonder if this changes in the Fall.

I can smell it outside right now.

This is interesting: Some of the high-res guidance is beginning to come around to the idea of showing convective development trailing back westward along a cold front with a weakening capping inversion into central VT/NH as soon as early overnight; but the timing and coverage of this activity still is pretty scattershot across the high-res suite. This could ultimately end up being a nowcast situation, but given this trend I couldn`t really justify NBM`s nil PoPs. Opted for up to 30% PoP along the MA/NH/VT border between 4-7 AM Wed, then slowly sagging southward through the day. If any storms develop, they would likely become strong to potentially severe quickly given the degree of instability aloft and pretty strong NW mid-level winds, with frequent lightning, hail and strong straight line winds all possible, potentially early in the day as well. Low confidence but potentially higher impact if storms can materialize.

Debris clouds

In the old days with super El Niños, the strong low level westerlies would extend north from the tropics into the mid-latitudes like in 1997. During the 2020s, the subtropical or mid-latitude ridges have grown to record levels. So the westerly flow is much weaker with the high pressure dominating. The warm pool from Japan to north of Hawaii is allowed to continue leading to the persistent -PDO. This prevents the strong +PDO response that was typical in 1997 and 2015. This is also why we have see strong to record heat domes across the CONUS since May from time to time instead of the cooler typical El Niño pattern this time of year.

As I said, I'm going to wait until the fall before taking this seriously. If the strong winter signal is still there in September/October, then you know it's going to be a cold and snowy winter. 2009-10 was the last time a strong winter signal held in the fall during a developing strong el nino. Contrast that to 2015-16 and 2023-24, when there was no strong winter signal in the fall months.

Humans survived the Cubs and the Red Sox both winning the Series. We will be ok (unless Cleveland wins it)

67 when I left the house. Got a mow in yesterday before the heat hits, first one in like two weeks.

Nice MCS coming into Maine and NNH to start the morning.
