Also not seeing any obvious signs of rotation but could be one heck of a gust front incoming. Can anyone else tell me if that's what I'm seeing on the relative velocity plot?

Looks pretty intense on radar as well.

In the truck heading into the backside of a squall line on 76 near Hershey.  Its heading northeast with a stronger line behind it.  A lot of heavy rain, haven't seen lightning but there were a couple cool rainbows.  It was severe warned, I thought I saw some weak rotation on the trailing side of the storm but it's hard to tell. There was also a big spud cloud .  Haven't come out the front yet but there was about 12 cars pulled over at mile marker 263 we just passed. 

 

Edit: came out the front and temp went from high 70s to high 80s on truck thermometer which is not that accurate.  In this radar snapshot you can kind of make up a little hook which is exactly where I thought I saw some weak rotation but I dont have access to base velocity data so maybe it's just the way it is. 

Also the radar is like 5-10 mins behind the location likely so my location during that snapshot is likely inside the storm.  

 

Ooph. Nothing like driving on the turnpike in a downpour--I used to have to drive 76 a lot for a previous job and got caught in more than a few. Hope you get home safe.

Lots of lightning with this one...  Seems to be headed NE or ENE

85.6°F and 56% RH. Humidity appears to be on the rise. I wonder if any of that rain out west will make it over here.

Geez Louise!

Temp made it up to 90 here yesterday just after 3 pm and during our bbq, we could hear thunder rumbling continually off in the distance and it really clouded over significantly. But I had been looking at the radar and most of the storms were running NW --> SE through Delco (I was in Montco yesterday), with a few cells a bit north of us.  We never got any actual rain thankfully, although at one point it got pretty breezy as something must have been close by.

Currently 78 and overcast, which I guess is keeping the temps from shooting up quickly like they did yesterday (where it hit 86 here before 9 am), with dp 68.

I spent the afternoon at my parents' near Oxford, and we got significant rain from about 4-6pm. The storms over Chester County seemed more or less stationary and were torrential. Afterwards it cooled to around 70°F but with near to 100% humidity; I set of a few fireworks early since my brother and sister-in-law had to leave early and I was completely drenched from the mere effort of walking back and forth across the lawn for ten minutes.

I don't want to seem alarmist, but I'm struggling to recall the last time it rained without thunder, lightening and flooding. It just doesn't seem to rain gently around here anymore...

That all said, it looks like another disgusting day outside with 79°F and 93% humidity as measured by my little remote station. Ugh.

Small but powerful storm just blew through. Completely different from the last time, where there was literally continuous rumbling thunder throughout the event; this time there was a whole lot of flickering and very little thunder... until the storm passed by. Now my apartment is shaking from the thunder every minute or so.

Torrential rain once again overwhelmed the gutters. Cooled right off though, which is nice. 70.5°F and 89% RH.

This upcoming pattern would also be more about MCC/MCS complexes moving through the region potentially, no?

Judging by what's happening over Wisconsin today, I'm inclined to agree with you.

Had near constant thunder preceding the line that just came through. Then it poured enough to completely overwhelm the gutters (again!). I think we even had a brief moment of pea-sized hail towards the end as well. Was reading 89.3° right before I went out to check on things; now it's down to 69.4° F. Holy temperature gradient, batman!

Got some unexpected training storms just now; has been steadily raining for at least a half hour with individual cells forming over me and then trailing off the the northeast. Even saw and heard a few flickers and rumbles of lightening and thunder. Overall, lovely stuff to fall asleep to, if only I should be so lucky. Oh well. It's 69°F with gently falling rain, feels a bit like the kind of distantly stormy summers of my youth growing up near here. I'd love if the entire summer was like this.

Weird storm line coming through. Coatesville was surrounded in angry red radar returns while remaining completely calm as the storm passed. It was almost like we were under a bubble.

Had some moderate rain come through and now the temp's down to 73°F. Today's weather (at least IMBY) doesn't appear to be nearly as violent as yesterday or Tuesday, thankfully.

Getting an EAS on phone for Flash Flood Warning (here in Philly).

Same. About to get hit with all that rain near Coatesville. Luckily, I think I'm no longer in any danger of hail; unluckily, my wife is trying to get home from Exton and the 30 is guaranteed to be a parking lot.

Have two storms closing in near me near Coatesville. Worried about hail. Sky looks angry, lots of scud moving around under the cloud deck.

And 12Z NAM 3km looks nasty this evening

To my untrained eye it seems most of the action out West seems further South than this time yesterday, More in Kentucky weren't the storms starting to fire in Ohio this time yesterday? Ill take a nice Thunderstorm but after yesterdays action Im not sure I want to see that again. 

New mesoscale discussion is out: https://www.spc.noaa.gov/products/md/2019/md0881.html

   Mesoscale Discussion 0881
   NWS Storm Prediction Center Norman OK
   1106 AM CDT Wed May 29 2019

   Areas affected...Portions of eastern OH...the northern WV
   Panhandle...much of PA...and NJ

   Concerning...Severe potential...Watch likely 

   Valid 291606Z - 291730Z

   Probability of Watch Issuance...95 percent

   SUMMARY...Scattered severe thunderstorms are expected to develop
   this afternoon. Large hail and damaging winds should be the main
   threats, but isolated tornadoes will also be possible. Watch
   issuance is likely by 17Z (1 PM EDT).

   DISCUSSION...A shortwave trough over central OH and Lake Erie at 16Z
   will move eastward today across PA and vicinity. Isolated
   thunderstorms have recently initiated across central OH and
   northwestern PA in association with this feature. A belt of strong
   50-65 kt mid-level westerly winds will be present across eastern OH,
   much of PA, and NJ today. Long, nearly straight hodographs through
   mid levels and related 40-50 kt of effective bulk shear should favor
   scattered splitting supercells early this afternoon. Large hail will
   probably be the initial concern with this convection, with some
   increase in the damaging wind threat with time as storms potentially
   congeal into one or more bowing line segments as they move
   east-southeastward across PA into NJ. A marine front located over
   the NYC metro area and adjacent northern NJ will likely limit the
   northeastern extent of the substantial severe threat this afternoon.
   In addition to the large hail and damaging wind risk, isolated
   tornadoes could also occur over mainly parts of central/eastern PA
   into portions of NJ to the east of a weak surface low where
   low-level southwesterly winds are forecast to be somewhat stronger.
   Watch issuance will likely be needed across this region by 17Z (1 PM
   EDT).

Camped out for 20 minutes in the basement. Only rain and thunder here, but man did it look wild outside right before I called a general retreat for the fam.

Just got a tornado warning alert on my phone, but I think it's for the storm up in Berks.

Edit: I looks like it's actually for the storm just to my east, near Coatesville. Time to head to the basement...

That line/cell blowing up over northern VA looks pretty juicy, even after losing diurnal heat. Highly convective with lots of lightening. I think I might be telling mom to put the horses in tonight, since all it takes in one loud crack to drive them crazy. And crazy horses in a storm usually means busted stuff and hurt horses.

Just became quite gusty here in Thorndale.

Temps back up to 71 (from 66 just a few hours ago) and now hearing some gusts outside.

Watches just went up for like all PA counties west of Chester Co. Just a matter of time...

The SPC severe threat isn’t until overnight here. Guess we’ll see.  It’s about wind and isolated tornadoes anyway, not typical summer severe/fropa 

SPC going all out with tornado watches south of the Mason Dixon line. I wonder if the trend will continue into our neck of the woods, now that we're going to start losing the diurnal heat. Tricky setup, but yeah it also appears to me that they're being overly cautious given what's on the radar and the marginal CAPE and LI values.

*Edit: However, nearly every meso model has us under the gun from like 3-6am.
