Central PA Summer 2026 Discussion/Obs Thread

Everything N of State College wants to spin today. Multiple tornado warnings 

[Yardstickgozinya]

I'm picking up abnormally, strong lightning strokes on my Am radio stations. The strokes generally don't cause this much interference at such long distance. 

[Yardstickgozinya]

Indeed A cell out there somewhere right now putting out some insane LEMPs. Tune in to an unused, a m frequency and listen you have to choose an a m.Frequency, that puts you between a tower and a storm. You'll know when you get there, you'll hear it.

[Yardstickgozinya]

Anyways, i've talked about this for several years and no one's ever really responded to it. But i've used LEMPs for years while i'm driving and working to know what's going on out there. Think of Cipher in the Matrix. Once you've listened long enough, you can make out the kind of stroke,  whether or not it's getting closer and intensity. 

In the context of storms and meteorology, LEMPs stand for Lightning Electromagnetic Pulses. [1]

They refer to the powerful, disruptive electromagnetic waves naturally radiated into the atmosphere during a lightning discharge. While they may not pose a physical shock risk to humans directly unless struck by lightning, they can induce dangerous power surges that damage or disrupt electronic devices and power grids. [1, 2, 4]

Because lightning activity and cloud-to-ground strikes are a primary indicator of thunderstorm severity and structure, meteorologists utilize artificial intelligence and ground-based sensors to analyze LEMPs to understand a storm's behavior

Big thunder, big shelf cloud approaching HBG

[Yardstickgozinya]

Light rain and thunder over head here at the beaver creek inlet at Pinchot park

Edit for update

Looks like I just got missed by something a little bette.  Watched a couple forks come out of that lowering hiding in the rain.

[Blizzard of 93]

Heavy rain & wind in Marysville.

[canderson]

Missed the city but I bet @Blizzard of 93 got hit good 

[Voyager]

Heavy rain here but no lightning or thunder

What do you guys think this line in Central PA will do this evening when it reaches the Susquehanna Valley?

It’ll likely weaken considerably 

[Blizzard of 93]

.48 of rain in Marysville from the first round.

I have exactly that amount here. Tornado Warning in the southern part of the county but really just a couple of good showers here, thankfully.

[canderson]

That line won’t make it over the mountains at all. A shame. 

[canderson]

Moving on to Thursday.  I tend to think CTP is going o be right and forcing will be so strong it creates an environment here that kills severe storms. We’ll see. 

[Voyager]

Ended up with .67" from yesterday's rain and storms.

[pawatch]

Ended up with .22” of rain. 32 mph wind gusts. Most of that happen in about 10 minutes.

57 degrees this morning and currently cloudy.

.26 here.

[Superstorm]

0.64” in the rain bucket. Nice drink for the lawns and crops.

[Mount Joy Snowman]

Low of 61 with .35" of rain.  Beautiful days ahead before things turn interesting for Thursday.

[canderson]

It feels glorious out this morning!

Thank you for sharing that.

Kyle Elliott at MU is very unimpressed with this Thursday's setup, he believes that both the timing of the pre-frontal trough as well as westerly downsloping winds will lead to a "very marginal" severe threat. Right now he's leaning for showers with an imbedded rumble of thunder. I'm on his train for now for sure!

Did anyone catch the rotation on a cell in southern York county last night? 830ish? The cell ended up being warned as it moved east but should have been warned before that IMO
