The guy struck by lightning in the next town over, Hammonton, on July 3rd, passed away. And I didn't know this, his father was also killed by lightning 48 years ago. What are the chances of that? :lightning:

HAMMONTON, N.J. - July 14, 2011 (WPVI) -- The story seems almost unbelievable, but the bark blown off an old sycamore tree is a reminder this tragedy is all too real. It was in a Hammonton backyard that 54-year-old Stephen Rooney was struck by lightning at a family barbeque July 3rd as he stepped away from the crowd to light a cigar. The party host, Rooney's cousin and next door neighbor, Funzi Digerolamo, says a giant bolt shook the yard. "Hit the tree, went up the tree. It electrified all through the root system of the tree at that time so he was standing right in the electric field," Digerolamo said. Digerolamo's son Scott was blown right off a bench, but survived. Steve Rooney died five days later. Just before he was hit, Rooney downplayed concerns about the lightning. "He had just said that lightning doesn't strike two people in one family right before it happened, not long before it happened, he said that," neighbor Paula Weisbecker said. Lightning is not supposed to strike twice, but in this case it did. Steve Rooney's father George was also killed by lightning 48 years ago when Steve was just a 5-year-old boy. The odds of this happening to a father and son are astronomical. Everyone is stunned that a bolt of lightning could claim them both, almost 5 decades apart. "It's hard to imagine two people in the same family getting hit by lightning. It's crazy," Paul Hoffman of Hammonton, New Jersey said.

Before the ridge gets here at the end of next week, we might have a shot at some MCS activity early in the week

Yeah, we may have two chances of an MCS topping the ridge and then riding near or across parts of our area. Looks like potentially Monday night (aided by a surface front also dropping southeastward) and again Tuesday night with the actual ridge axis sliding eastward.

well 0z Nam is game for an MCS early tues AM. I'm having a tough time uploading pix, anyone else? (twister data pics tbe)

Pretty potent shortwave comes over the city with 60-70kts of bulk Shear. Because it's overnight, not too much instability, but a nice set up nonetheless. Nice helicity values due to that.

Just forwarding the run, not making a forecast.

yeah looks like it spins up a weak 1008 mb low and dumps like 2-3"+ for a lot of the area

outlier to the others...mount holly is tossing it.

Edit, 6z shows no MCS and shows scattered line of thunderstorms crossing the region between 9 PM and 3 AM...much more sensible solution.

IMO, they probably cross a bit faster (7-1?). I'm not too keen on wholly accepting the EC and GFS straight up given how poorly they are handling the storms in Ontario this AM. That activity may be the stuff to watch (or part of it, at least) later on.

I'm trying to be optimistic today and hope the 00z NAM plays out in some way...other models like the Canadian and Ukmet drive some sort of activity through our late tonight into early tomorrow as well...with the GFS being the tamest of the 4 models I've glanced at. Can't wait to see what the 12z info shows. I'd be happy with .25"-.50" soaking overnight in one form or another. I don't need severe stuff blasting through, just some rain.

Storms firing in NW PA now, heading SE, along with an MCS in E MI. We'll see what makes it here later on. Liking the radar trends as of now.

Yup, trends are good for once. CAPE looks good, PW is high, might get a nice soaker. Too late for the lawn though, it's cooked. State College has (low) tornado possibilities in their statement for those cells too. Should be an itneresting evening.

if it doesn't make it here before sundown, you can forgot about the storms. A lack of instability in our region today, and that'll wane after sunset. SB cape and MU cape aren't very impressive, mid level lapse rates and shear are the only things going for us here. Who knows, i've seen stranger things.

Hopefully that stuff makes it into the NW burbs by 8 or so.

It looks like crap for the Philly area as of now...getting split by the stronger storms near Harrisburg that will travel down the Susquehanna while stronger activity is firing near Scranton with its sight set on going to the Poconos.

if that line just north of i80 holds it will come into our area. But im not sure it will do to the junk out ahead of it.

Yep, getting split to the west and east. Just bad luck this time.

That whole line up to the north is tracking right at the whole area. IF it holds together, we'll be fine, and get hit sometime after dark, which was called for in the last couple days. Question is, will it hold together.

I said this would happen an earlier post today. Frickin past history of splitting t-storm cells as they move east is killing us. I noticed Mt. Holly lowered the percentage of precip for tonight. Good call. I hope the line north of I-80 says together, otherwise I see no precip for us for the foreseeable future. The corn is spiking pretty bad in some parts of the county.
