Saturday, July 18, 2026 Thunderstorm/Severe Weather Potential
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.

Originally late afternoon. But it appears any low-level shear is gone and cape never built with our socked-in cloud cover and smoke. It might storm later but I don’t personal see fuel in the HBG metro. -
2026-2027 Super El Nino
jaxjagman replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
Since the early 1980's when the DMI hits a certain porportion its always followed by a LaNina the following winter.As if this is one of those years is unknown ATM.DMI peaks into fall so there is a few months to even seemingly have an idea -
2026 Mid-Atlantic Severe Storm General Discussion
ThePhotoGuy replied to Kmlwx's topic in Mid Atlantic
Extensive damage throughout my neighborhood. Over 20 separate homes with trees laying on them. Trees down everywhere. Telephone poles snapped in half. Neighbors keep saying a tornado went through the area. Luckily no damage at the house but no power.- 1,150 replies

Missed the worst of the T&L but got the rain, 0.72" and counting

if you have fire tv download myradar app can zoom into street level and no clutter

Yeah no kidding!

Mr. J just went out to pick up our dinner. Opened the door and walked into a sauna. This is in Lewes DE by the way so the storms have not gotten here yet.

So I asked AI to review the Chester County PA raw data set since 1893 to find if there is a significnant p-value that show warming in this County. The AI review of the data finds No — the raw Chester County composite does not show a statistically significant warming trend since 1893. The numbers (1893–2025, 133 years) Linear trend: +0.0043°F/year (≈ +0.43°F per century) 95% confidence interval: −0.0012 to +0.0097°F/year — this interval includes zero, which is the definition of "not significant" R² = 0.018 (the trend line explains less than 2% of year-to-year variation) p = 0.128 — above the conventional 0.05 threshold A robust version of the same test (Theil-Sen, less sensitive to outlier years) gives essentially the same answer: +0.40°F/century, still not significant So statistically, you can't distinguish this composite from a flat line over 133 years. Only if we allow NCEI post hoc adjustments to the raw data can we glean any signifcant p-value warming across Chester County PA!

Drizzle It's rained twice today and yet to wet the ground.

Anyone have a good radar they’re using

More days than not when svr wx occurs and it is favorable for supercells, deep layer (0-6 km) shear is good/great, but low-level (0-1 km) is weak. So you can get intense supercells w/ a nasty mesocyclone at mid-levels, but no real signature for rotation or a TDS at low-levels, and thus no tors. I've seen storms like this before in the Plains, You'd think there would be at least be an organized wall cloud for such an intense mesocyclone aloft, but just ragged, disorganized scud. Yet the storm is dumping giant hail and has incredible structure! A rule of thumb I look at for a basic start for a decent tor day is winds at least 30 kt at 925 mb. That gets you you low-level speed shear, which is important. Next, is there any veering of the winds sfc to 850? Low-level directional shear is paramount, esp.for sig tors. Is there a warm front involved? We are taught the cold fronts are the big tstm producers, and they are, but some of best intense tornadic supercells are those that form on or very close to a warm front, and ride along it. Winds locally are backed at the sfc just ahead of a warm front, but veer quicky aloft, so localized shear/helicity can be much higher than the environmental shear/helicity. Typically in most supercells, the mesocyclone (lowest pressure), is at mid-levels, the if conditions are right, the low-levels can organize for solid rotation. The exception is for TC environments. Supercells are often very low-topped, (might not even be 15,000 ft!), and deep layer shear (0-6 km) is not that great, but low-level shear (0-1 km) is excellent,owing to the strongest winds in a TC often found 925 mb to just a few 100 ft above the sfc. So you can get tors in swarms (look at what the remains of Ivan did in VA in Sep 2004), but most are weak, even a higher percentage from their continental counterparts b/c you don't have much CAPE in a TC environment, so updraft acceleration typically can't support strong/intense tors.

On my third or fourth storm of the day. This one is the most intense so far. Lost power for a moment but it’s back now. 80F/DP 78F -

Right in the thick of that warning issued for Montco. Probably ~25mph gust with moderate rain. Worst was a CTG strike on the pole down the street. Power back came back in a few minutes though -
That was pretty intense. Winds probably peaked in the 40-50 mph range. Just like this morning, the lightning was impressive. Lost power briefly. 1.35" for the day.

Voyager replied to Voyager's topic in Upstate New York/Pennsylvania
So I was checking out AccuWeather's future radar, and it shows the Williamsport complex dropping southeast to about Hazleton and then curving east northeast. Does the upper air steering currents support this, or is it's depiction likely wrong?
