Apparently there was a fairly strong Tornado spawned by this MCS in upstate NY (check their page for some damage photos). This setup kind of reminds me of 07/18/97 where there was a long lived MCS that tracked mostly through PA and caused widespread damage and 60+ wind gusts in NYC metro area. We'll see if this thing holds up as well.

Also, there is a rear inflow jet notch literally pointed at Manhattan.  Y'all are nuts to call a skunk right now.

I wasn't calling for a skunk at all. I am curious to see what happens with the heat island as the storms head through. Otherwise I think this has the best chance of regoin wide severe so far this season

Oh god, that stupid article again. It's the dumb thesis that will never die.

Yeah widespread 65-70 mph gusts here with that storm. This line seems to be weakening but we'll see if it can pulse back up

Meh. It's starting to weaken and it indeed looks like NYC is going to get split.

Right on cue, probably nothing more than a brief heavy shower. Severe weather around here is non-existent. I've seen more t-storms during the winter months than summer.

That line is not weakening.  Do you guys see the big area of 50mph+ wind pointed at NYC?  That is the rear inflow jet behind the MCV being forced to the ground.  That's what makes the reflectivity look weaker, but that's a sign of a strong line that can potentially put down a wide area of wind damage.  It's not as sexy as the bow down around Allentown but it's just as likely (or more) to verify severe.

A fierce storm swept the region this afternoon, causing widespread emergency calls and knocking out the Susquehanna County 911 Center.


Anyone needing emergency assistance in Susquehanna County should go to their nearest fire department or call state police directly at 570-465-3154. 

By 5:40 p.m., PPL Electric Utilities reported 1,939 customers were without power in Lackawanna County. The largest outage concentrations included about 725 households without power in Scranton, 863 households in Archbald and 543 households in Clarks Summit.

Meanwhile, Lackawanna County 911 center received numerous calls about incidents such as downed trees. Dispatchers sent fire crews to a home on Greenfield Road in Carbondale Twp. for a report of a lightning strike about 5:43 p.m.

Watch the portion of the line that runs from I-80 to the NY/NJ border to possibly re-strengthen.  It got disrupted on the initial bowing/reorganization of the line but it still has significant forward speed to it and could re-fire moving into unstable air...at least for the next 45 mins over NJ.

It's falling apart dude probably not even going to see thunder around the NYC area

No marine layer in this case

Yeah I'm at the beach right now. Not your typical ripping onshore winds and cool temps we usually have here before an MCS. So if anything screws this up this time it's not the ocean

It felt like it a short while ago, it got cloudy here with winds gusting from the south. Still mostly cloudy but no ripping onshore winds.

Doesn't make a difference at this point.  Looks tame for areas east of Newark.  Breezy with some rain unless there's some strengthening.

I think it may have been the WNW downslope flow with the lower dews around Newark today.
