Thing is today is supposed to be much more widespread than yesterday as we have a clear trigger.
-
No such thing as heat lightning. It's a distant thunderstorm.
-
Funny enough, that's exactly what the HRRR is showing.
-
Would love a storm to roll through before the fireworks to cool us off. Between the flyovers and the fireworks maybe? Another one after the fireworks to clear the smoke out would be great, but that’s probably too much to ask for.

Hopefully the gif works. Fun representation of the temps with the impact of the convection later today from the RRFS.

Comparing the soundings from yesterday to today and the whole temperature axis is shifted a bit cooler. On a different note, what a thermodynamic environment for severe weather today. We have 1500 SBCAPE at 6am which is... pretty good. Sadly, like our of all severe weather potential our ML lapse rates probably suck with a value of *checks notes* 9.3 C/km? If we get storms they will have no issue growing up to the tropopause and then crashing back down. I'm up in northern PA so I'll miss out on the fun, but yesterday night had some of the best lightning storms I've had in years. Pouring rain, loud strikes, and constant heat lightning beforehand.

12z IAD has over 4,000 surfsce cape and over 1,500 dcape, but a convective temp of 100°. There's rocket fuel to tap if something can take off.
-
Temps running about 1-2 degrees lower than yesterday through 9am.
-
DP slightly lower this morning at 75. Currently 84/75 climbing from low of 77 after high of 98 yesterday, same as Thursday.

The gust front was insane. We were golfing by the lake yesterday and we’re approaching the green on 9. RadarScope showed the storms were roughly 10 miles out and looking to the west it looked like God took a massive leaf blower to the bunkers! We were putting easily in gale force winds and had to keep our sunglasses on due to the amount of dust. Coming back home you could visibly see the dust cloud to the east, just an insane amount of wind ahead of the line. Reminded me quite a bit of when sea breeze thunderstorms would hit in South Carolina, whenever you have those 90°/70°+ days it seems the outflow is amplified to the max. It flipped on a dime though, we had perfect conditions on 8

E PA/NJ/DE Summer 2026 Obs/Discussion

Well parade got cancelled. Disappointing but also understand why. We decided to put the antique together and do a quick march through the neighborhood for all the guys that never got the chance to pull the cart. We did three blocks up and back at 8:30 and when we got that done we were all glad the parade was cancelled. I think the city told them no parade. Roads are buckling in Chester County. Pottstown Pike in West Goshen is pretty nasty and this morning the Rt 100 Spur into Exton has concrete breaking up. Be safe today looks nasty later! -
Lots of the Macys viewing areas are nowhere near a place to take shelter…. On the other hand you can’t cancel July 4th 250 fireworks lol

Seems less hazy this morning to my eyes. Sky is a deeper blue. Signs of the ridge weakening?

2026-2027 Super El Nino
GaWx replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
July 3rd cooled back very slightly. So, the DMI 80N+ mean Arctic temp still hasn’t reached 0C! The old record latest was 6/20/2013.
