Going to end up with convective cloud debris today too and may even see convection begin to pop early afternoon...or maybe closer to mid-afternoon. Pretty healthy looking convective complex (at least from satellite presentation) in Quebec racing southeast

Even the GFS has a quite a bit of elevated CAPE with at least western sections on the instability gradient. It will be an interesting evening/overnight, especially if the NAM sort of verifies with the advection of rather impressive MUCAPE. The HRRR I think has been solid with the idea of convection moving into the region this evening but I think this may end up being a bit more impressive than modeled. These are tough environments, even more mesos to handle

Bring it baby

Just an insane presentation still. Even looks like there may be a rain wrapped tornado

I don't know if I would necessarily bet against it, however, I would put forth some caution into the extent of what some of the forecasts are in terms of its strength. I think its just way too premature to start tooting around x,y,z are happening because we have a super-strong that is developing. I still don't necessarily see how a lot of comparisons can be drawn to how the atmosphere is responding to something developing, particularly when it comes to the ocean. There is quite a time lag between ocean-atmosphere response. It's not like the atmosphere is going full EL Nino mode because the ocean is warming...there will be some time before that warming in the Pacific has a full-fledged impact on the atmosphere. For example, most EL Nino's, particularly stronger ones will tend to peak during the Fall at some point and begin to weaken moving through winter, but its not until the winter months in which you see a much stronger correlation to the impacts of EL Nino.

It's more of the fact that everything is being blamed on something which has not yet become established and its not like these episodes of heat and large ridges are solely a response to EL Nino.

Absolutely ridiculous. So extra heat is being added from something that isn't established yet and is only in the developing states?

Correct, I should have been a bit more clear with this aspect

was looking at vorticity rolling through/shear/instability...but mostly focusing on the shortwave rolling through as the driver for anything. If that shortwave is nothing or relatively weak then yeah we won't see much of anything

Actually I kind of like where that has the 30% area for D3. Looks like the instability gradient (talking about gradient between moderate and extreme instability) may be eastern NY into western New England. Something to watch because any development, particularly any cluster or complex, is going to ride that

Not bad for a D3

True, height falls are relatively meager. Certainly one of the negatives to consider

Looks like right along the theta-e axis. What happens tomorrow night could end up setting the stage for Wednesday too, particularly when it comes to any potential remnant outflow boundaries. We'll have to see how things time with shortwave energy and even shortwave strength but Wednesday has potential to be a higher-end severe day I think

Wednesday looks pretty solid

12z HRRR catching on to the 0z RRFS?

What winds can the radomes withstand before worrying about damage risk?

This thing is like Pac man, just swallowing whatever is in its path (luckily probably not much). Thing seems to have a nasty RIJ

Looks like its about to split

It's like a massive supercell MCS Those storm tops may be exceeding 70,000 feet lol

Holy shit

Pretty much what dendrite said. Also, add in it’s extremely difficult for us to be directly centered under the ridge so more often than not we’re on the periphery so that opens up the door for high cloud/convective debris. Also, it gets difficult to achieve higher end temps when dewpoints start pushing towards and into the 70’s

Good morning South Dakota

IMO, its much more difficult in these parts versus the PAC NW.

Just imagine the masterpiece of a symphony Beethoven could create based on the unison of hums from all of the A/C's that will be cranking full-throttle and non-stop for the next foreseeable future.

We kick off the month of July with a trough digging into the western United States and a large ridge of high pressure building into the midwestern states (I refuse to call this a heat ridge...another stupid, hyped up term) resulting in high heat and humidity building into the eastern third of the country. Here in the Northeast, we will find ourselves on the northern or northeastern periphery of the upper-level ridge. This will place us in a favor position for the advection of higher heat/humidity in the lower-levels while favoring a northwestern flow in the mid-to-upper levels. This pattern can be favorable for MCS propagation into the Northeast region as well as the advection of elevated mixed-layer plumes. In terms of severe weather potential, computer forecast models hint at some shortwave energy rounding the northern periphery of the ridge into the Northeast (uncertainty as to exactly where). With temperatures well into the 90's and dewpoints well into the upper 60's to 70's under the presence of steep mid-level lapse rates, the potential exists for moderate-to-extreme instability to develop with potential for 2500-4000 J/KG of MLCAPE with potential for 30-40+ knots of bulk shear. Should a shortwave work into this environment the potential would exist for numerous thunderstorms, including the potential for some of these to be severe with potential for damaging wind gusts, large hail, and even the potential for tornadoes if enough directional shear is present. The high heat and humidity has finally arrived
