And another classic miss from SW to NE.  Lots of thunder, wind, not enough rain to wet the ground and 1 mile north gets pummelled.

92/79 for a 109 HI

Deep thunder in the distance. Had to cut my hoops sesh short bc quite frankly I don’t like the idea of the smoke hiding the lightning. The grass here is mostly green…kinda wild seeing others to the east struggling to get precip.

One of the more humid days I’ve experienced here.

[Eskimo Joe]

While everyone is focused on the severe weather risk, we've busted into Heat Advisory criteria south of I-70. Some places pushing 110s for heat index.

[87storms]

Storm weakened a bit on the northern side, but still getting a good shower. Looks like Ballenger Creek area is gonna get rocked.

[87storms]

Well I thought it weakened, but just got pulsed by serious downpours and a gust that briefly knocked out power. Places getting cored by this storm are gonna love it. 

[87storms]

Rainfall rates are legit. Someone might get 2”+ imo

My youngest just got caught out in it driving. That tornado warning went up just south of my house. Looking at radar some heavy stuff went over my house. I am in DE and relaying stuff back to her.

Oh wow, you’re missing a fireworks display. This is one of the finest lightening shows I’ve seen. Looking south it’s cg after cg.

Finally raining....about .3 so far...!

I got caught a little off guard on my 10 mile hike this morning. That sun came out and the heat index went nuts. It kicked my butt a little bit. Prime environment for big rainers for some.

[Amped]

Clobbering Frederick now, looks like its headed down I70 towards Ellicott City later. Maryland's 2 flood magnets of course.

Part 2 incoming

[wxmeddler]

I mentioned in the severe thread, but the lightning today region wide in these storms will be no joke. A combination of lots of water and lots of lift in the phase transition layer is going to equal a lot of lightning.

Just had a neighborhood strike. Absolutely incredible lighting display around here with these storms. Top 10 for me.

Well I am under a Tornado Watch over here in Deleware. And it is very humid and windy. Checking my station and it is at 2.61” so far. That is after the .61” from this mornings stuff that went through. Kid made it home from dropping off her friend at her house. Will have to wait and see what goes on over here. 

[87storms]

This next storm is bonkers. Premier event here.

[aldie 22]

Im at my sister's in South Point Ohio but back home rain gage says .37

[Mrs.J]

Just got the alert for a Flash Flood Warning for my area. Thankfully it looks like the rain is almost over. 

[pazzo83]
