What a difference a day makes!  It’s hot and humid at DCL.  Getting the outflow from that cell now and watching the more ominous line behind it in WVA.

1.61” here so far. Definitely sitting under a training line. 

[AdamHLG]

I live in a warned area earlier tonight in Chestnut Ridge area Baltimore County. My property took a direct strike tonight - split a massive tree in our front yard and split it down the center. The charge got picked up by our landscape lighting and entered the house and blew up the lighting transformer in my garage (during initial damage assessment there was a haze in garage and 911 was initiated. FD came out and secondary search found the transformer blew up and blackened the wall (that was the haze) , took out 2 GFCI outlets that are now blinking red and dead, my main network switch is dead , a raspberry pi Homebridge computer is dead, my main tv is dead , and I still haven’t finished damage assessment. . Massive tree and its branches down in my yard. Pics when I get internet back I have half a bar. Nobody injured.

I was siting on front steps 20 min earlier listening to very distant thunder and saw all the flashes afar and on RadarScope (while cells still in Frederick / start of Carroll). I had some time but then the TSW was issued so I came inside well in advance. Never - ever - expected a direct strike. Holy **** was that scary. The tree 25 feet away. I have a little ptsd about it and new respect for lightning (not that I ever didn’t have it - but wait till I post the tree and transformer tomorrow.

That was closest strike of my life with property damage on top of it. . Severe lightning direct hit unlocked. I can be done now.

[Harv_poor]

That seems awlfully close. Is Chestnut Ridge up a few miles  on Falls Road or Greenspring from Greenspring Station?

Wow! Glad it was not worse. The lightning was especially intense with that first line last night. Saw quite a few cloud to ground. We have whole house surge protection in our panel but the kids unplugged their PC’s and I took my laptop off the charger just in case. Keep us updated on the damage.

It’s the intersection of Greenspring and Ridge Rd. I ride my bike through there a lot.

So glad you and yours are ok. Hope insurance helps with the electrical damage.

Wow, that’s crazy.  I’m glad you are all safe.

[high risk]

       CAMs have swung back and again look decent for the I-95 corridor, BUT those solutions are contingent upon heating into the 90s.      It does look like there is some clearing approaching, and I would expect us to rapidly torch if the sun emerges, but we'll see how this plays out.

DAMN. First, I'm so glad that you and your family are safe. I saw another one of our forum members commented on your experience (from the Springfield, VA area, I believe), which was equally harrowing. I was a late teen, hunkering down with my mother in my childhood home in PA, when we had a direct lightning strike at the top front of our house circa 1988. All appliances started beeping, our main TV was fried, there was a definite electrical stench in the air, but nothing was seriously ruined in terms of the electrical system. As expected, the blinding flashes in every window were instantaneously followed by ear-splitting thunder...and my mom and I had ringing in our ears for a couple hours afterward.

 

Certainly, we did not sustain the kind of damage that you all did here...unfortunately. As a weather buff, you ALREADY knew the dangers of lightning, and we can obviously never predict when it strikes...but it is a force of nature NOT to be trifled with.

 Mesoscale Discussion 1489
   NWS Storm Prediction Center Norman OK
   1111 AM CDT Sun Jun 30 2024

   Areas affected...Portions of central/eastern NC/VA...MD...and DE

   Concerning...Severe potential...Severe Thunderstorm Watch likely 

   Valid 301611Z - 301815Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Thunderstorms are expected to develop over the next couple
   of hours, posing a risk for damaging wind gusts. A watch will likely
   be needed for portions of the region withing the next 1-2 hours.

   DISCUSSION...Portions of northern VA into MD/DE continue to
   experience greater cloud cover at midday due to earlier day
   convection. The airmass across this area has been slower to recover
   as heating has been somewhat slower than surrounding areas.
   Instability increases with southward extent, and to the east of a
   surface trough, across southeast VA into northeast NC. With time,
   much of the region should achieve moderate to strong destabilization
   given surface dewpoints in the mid 70s F and temperatures climbing
   into the upper 80s/low 90s F. Vertical shear will be strongest
   (around 25-30 kt effective shear magnitudes) across northern
   VA/MD/DE, while decreasing with southward extent into NC. 

   Convection may first develop in the uncapped and moderately unstable
   airmass near the surface trough across parts of NC into southeast
   VA. As airmass recovery continues across northern portions of the
   MCD area, additional storms are expected to develop over the higher
   terrain of northern VA and shift east through late afternoon/early
   evening. Thunderstorm clusters will mainly pose a risk of damaging
   gusts, with potentially some better organized/more intense bowing
   segments possible further north where better shear overlaps the
   moderately unstable airmass. Regardless, portions of the MCD area
   will likely need severe thunderstorm watch issuance within the next
   1-2 hours.

Bright blue skies. Temps taking off.

Looks like Liz Leitman is on the desk at SPC today. She's solid. Should be a good day for you all.

Appreciate the summary provided in banter but I don't believe you're clogging up anything here -- of course, all of us reading this thread love to follow the severe stuff. But sharing your experience reminds us to be careful when it's showtime.

[dailylurker]

Blue sky here and purely tropical. Temperature is 95 and the dewpoint is 78. If that isn't enough for storms I don’t know what is.

Classic day of decent lightning and probably some real nice downpours.
