Central PA Summer 2026 Discussion/Obs Thread

[Superstorm]

These couple of storms just popped up over the past hour from nothing. 

Those will probably feed a nasty storm complex east of Lancaster.

at least it won't be hot these next 10 days because it looks really dry

Great week to be at OBX. That happened to us several years ago...our family's week was highlighted by 10.85" of rain in Hatteras. Water, water everywhere.

Latest HRRR continues to not be impressed with storm/rain chances the rest of today for many of the LSV area aside from areas near the MD border. The real bust for now has been central PA where this light to moderate rain all day and cloud cover has really put a lid on things

We’re driving down to Columbia. I don’t see it storing there (like Harrisburg

Yeah, I think we're just about done as the last cell has moved northeast. I didn't think we'd pick up close to an inch in the forecasted first round. Ended up with 0.92" in my backyard. Locations to my immediate north (Hometown, Lake Hauto) are showing between 1.25" and 1.50".

I had to get to work.I'm not sure exactly what happened to that the expansive break in the clouds geo was showing this morning, but I maybe got 45 minutes of sun today. Last night's mcs  really seems to have things all mucked up now with debris. The cold front's still out in the western Ohio with plenty of time for things to happen. There may be no sun but we still have plenty of time and a powerful system to plow that cold front through. I'm sure the severe risk is falling, but we got a long way to go to say that we're done for the day with storms.

There is a line coming across Lake Erie now…WAY far away but there is a chance…

We had very little sunshine, and really not much of anything this afternoon as far as storms were concerned.

A complete dud down this way with respect to any type of meaningful rain or severe. 

[canderson]

We drove through India by heavy rain by Elllcott City. That place always floods.

Zero measurable rain here so far but steady light rain has commenced. 

The line moving towards us is currently TOR warned...

I know a lot of people have given up hope. And I i myself assumed severe is over, but as of the last updates, at 7:48pm Nws seems to still have their eye on the sky. I would have thought they would have changed that if they weren't still foreseeing some possibilitie.

1) Scattered to numerous severe thunderstorms are expected this
afternoon through the evening hours today.

.DISCUSSION...
KEY MESSAGE 1: Scattered to numerous severe thunderstorms are
expected this afternoon through the evening hours today.

We are in standby mode for now as the copious amount of
energy/lift/strong upper level diffluent flow (associated with
the left exit region of a 100+ KT jet) has produced an
expansive area of weak convection embedded in light to moderate
rain. All of this thick/debris cloud cover will prevent deep
convection through the early afternoon, but pockets of fairly
quick destabilization via breaks of sun should spread into
western PA and remain over our far SE zones to trigger some
deeper convection by or shortly after 18Z.

We`ll be closely monitoring satellite trends and meso-B
stability and shear fields to better hone in on areas under the
gun for potential impact of fast-moving TSRA.

[Yardstickgozinya]

I did notice the bottom of the conversation mention 18z but the update time is 7:48pm so i'm a little confused. I guess i'm just assuming they would take it down if they thought if all risk was over at that 7:48 update is the point that I was trying to make.

That line overall looks like dog doo doo.

Might end up with no measurable rain today. Ouch.

[mahantango#1]

.07 rain today, disappointed we didn't get more.

[Storm Clouds]

Tempest recorded .06 of rain and an 18 mph gust of wind today. What a fail…enhanced risk and everything lol.

The Great Chuck Chodes wouldn't have screwed it up this bad. Speaking of the king, he had a term for this kind of storm behavior. I believe he called it circle jerking the Commonwealth, but I could be mistaken.
