E PA/NJ/DE Summer 2026 Obs/Discussion

[SouthernNJ]

TPHL over Cheltenham/Fox Chase at 3:11 PM.  Damaging winds possible.

[JTA66]

Dark with thunder, but storms appear to be dying off as they approach.

[Hurricane Agnes]

Have hear 2 loud thunderbooms from the cells that are moving east of me.  There is some mPing report of >1" hail.

The dews crept into the low 70s but with the convection to my east, they dropped a few degrees.

 

Hit up to 89 after a 67 low snd before the popcorn started.  Currently 81 with dp 68.

 

[Hurricane Agnes]

Under angry blob with >2"/hr.  Have 0.57" in the bucket.  Temp 68, dp 66.

[Hurricane Agnes]

Sun back out.   Finished up with 0.90" of needed rain.  Currently 71 with dp 71.

[LVblizzard]

There’s been near constant thunder here for over 3 hours. Our only break was an hour ago when the first storm left and the second one hadn’t formed yet.

Have been watching the cell just SW of Allentown.  it seems to be reforming.

There’s been near constant thunder here for over 3 hours. Our only break was an hour ago when the first storm left and the second one hadn’t formed yet.

I had 0.90 in my backyard from the two cells today. I was not in the absolute jackpot for the region, but definitely did better than most.

[Albedoman]

finally, we received a share of the golden rain events today. Nealry an inch in brief but training heavy PWAT t- storms. Could surely use more of it tomorrow. It was a million dollar rain for the ag business in western Lehigh and eastern Berks County today.  Much more is needed tomorrow but its a start.

[BBasile]

Had an odd, but interesting storm here.  It blew up along a gust front, expanding from SE to NW.  It was dumping rain only about 2 miles away.  It wasn't actually raining here, but misting from the wind blown rains coming from the main rain shaft.  Eventually, it did dump rain here, but the progression was pretty cool to watch from the air.   You can see the mist being blown in from the drone time lapse footage.

Love the rainbow at the end of the video! 

[ChescoWx]

Despite our hot start to July we have turned much cooler over the last 10 days, which has brought us all the way back to average temperatures so far for the month of July. Today looks to be the most impactful day with flash flood threats although as many of you know much of Northern Chesco has not seen as much beneficial rains as the rest of the area. Shower chances will continue but not a wash out by any means through Thursday. We finally dry out on Friday with sun returning both Friday and Saturday.

[Mikeymac5306]

Few things beginning to pop in York/ Lancaster County. Nothing impressive yet though. 

[The Iceman]

Already a quick .40” from a cell that popped right over me. Radar lighting up to the west, I think we see multiple areas of flash flooding this afternoon. 

[MGorse]

0.13 inches yesterday. Let’s see what happens later today. Soupy out there with a dew point of 74F.

No dent in the drought here as yet this stuff is scattered

Yeah heavy storms rolling across Adams and York now. Pretty good shot of rain headed to MBY in Exton once it clears Lancaster County.

[Duca892]

Outside of occasional pours not much going on for the most part in Southern Lehigh County 

[Birds~69]

Let's hope the stuff to the W starts flaring up...

79F/DP 69F

[LVblizzard]

That cell over Allentown tried to go into tornado making mode. I was getting gas at Costco and I noticed some pretty intense rotation, despite radar not really showing it. Didn’t see any funnels but the motion in the clouds was pretty crazy.

[Birds~69]

Looks like a line is trying to form somewhat...a couple heavy downpours here.

76F/DP 65F
