Saturday, July 18, 2026 Thunderstorm/Severe Weather Potential
VivaManchVegas replied to weatherwiz's topic in New England
got another 1/4" of rain today, so that was good. -
That is an exceptional amount of CAPE (nearly 6000) for a location on the East Coast. I am surprised there were not more svr hail reports. Low-level shear is weak. 0-6 km shear 37 kt so there is your supercell support. I think the storm coverage was a bit too much and that is what precluded more sig svr wx overall. A bit stronger capping probably would gone a long way.

Expectations should always be low in our setups really. At least for me, part of the fun in all this is the "unknown". 99.999999% of the time (or some number that's essentially 100% without being 100%) severe weather here is not going to be widespread or even concentrated, its just going to be some reports scattered about and localized. But back to the fun...its the tracking and monitoring to see even if one storm produces...and if that one storm does produce, there is someone out there who was directly impacted. These setups are just so intriguing in that regard because the kinematics support the potential and generally instability is usually just enough to warrant some concern, but ultimately low enough to where maybe only a few storms will ever become mature enough to utilize the environment. -

A tornado warning now for portions of MD eastern shore and southern DE. -
Getting some additional rain here with continuous T&L
-
At the ducks game now. Hoping those storms fizzle or skirt south……

Yeah you are getting crushed again. Might end up with 5"+ over the last several days.

Well crap that escalated quick. Tornado Warning just to my West of the place we are staying.

2026 Mid-Atlantic Severe Storm General Discussion
high risk replied to Kmlwx's topic in Mid Atlantic
All of what you said is legit, but I'm leaning now towards the idea that this was an artifact. As you said, getting a strike super far away from the core is possible, but I think you need a much more powerful setup than we had today.- 1,153 replies

That was a lie, sideways rain and T&L, torrential 1.18" now.

Looks like the tornado warnings so far have been outside of the tornado watch (within the severe thunderstorm watches). -
2026-2027 Super El Nino
Stormchaserchuck1 replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
^I think we are still "evening out" a strong 28-year period of La Nina: Before this year, Per RONI, 5 of the last 6 years (20-26) have been La Nina. Per RONI, 7 of the last 10 years (16-26) have been La Nina. Per RONI, 11 of the last 19 years (07-26) have been La Nina. Per RONI, 15 of the last 28 years (98-26) have been La Nina. That's >50% La Nina since 1998. Since 1948, the tendency for reversal of multi-year ENSO patterns has been really strong. Here's the closest multi-year example: Only other period on record to have 5/6 La Nina's, until 2020-2026 (ONI):70-71: Moderate La Nina71-72: Weak La Nina72-73: Super El Nino73-74: Strong La Nina74-75: Weak La Nina75-76: Strong La NinaENSO tends to even out, historically. Here is what followed the 70-76 streak (ONI):76-77: Moderate El Nino77-78: Moderate El Nino78-79: Neutral79-80: Weak El Nino80-81: Neutral81-82: Neutral82-83: Super El NinoReally interesting that we didn't see another La Nina for 7 years after 70-76. Then again, it has also been really hard to go ENSO Neutral in any year: Since 1994, only 7/31 ENSO years have been Neutral, per RONI. 24/31 have either been La Nina or El Nino. Since 1994, only 7/31 ENSO years have been Neutral, per ONI. 24/31 have either been La Nina or El Nino. I don't know that we'll see a Moderate-Strong La Nina snap back this time. Cold water is not really building in the western-subsurface. Weak Nina would be my guess but I could be wrong! -

Happy to miss the severe so far, any risk of the smoke sticking around if the rain busts though? -

0.06" on the day. Still 81F with a 77F dew. HRRR is not optimistic for later on. No rotation... At all? -
You had this left mover (anticyclonic supercell) near Manassas earlier. You do not even have to look at the velocity to know this. The storm is deviating to the left of the mean flow and it has the flared NW to SE structure w/ the anvil streaming to the SE despite the storm moving NE! When storms rotate, it becomes complex as to the total motion vectors acting on the storm. Anticyclonic supercells rarely produce tors (in the NHEMI), but giant hail and microbursts are just as likely as w/ cyclonic supercells

ct_yankee replied to weatherwiz's topic in New England
Unimpressed with everything about this day, had zero expectations. It was always going to be a slopfest, there was only ever one run of one model that looked really interesting for my area, and obviously that ain't enough to get exited about, unless maybe if you're Wiz (just kidding). I did raise an eyebrow when the SPC expanded probs for spinners here but never really bought into that because experience has taught me they seldom do great with New England setups and I just didn't see anything that looked unusually good for tors and supes this far north and east, despite the decent shear. Could still get surprised, I suppose, but I consider that possibility increasingly unlikely. Maybe the next one, sigh... -
0.47”. I’ll take it, but we desperately need a region-wide soaker.
