SNE severe/convective thread IX...or whatever number we're on

Not sure. My yard has always been too full of trees with not enough open space to setup my rain gauge, however, during the late spring our landlord had the front porch removed as well as some of the trees and bushes so there is a bit more in the way of open space. I just haven't gotten to setting it up yet but probably will do so within the next month or so.

Why not just put it either on your front lawn(thats what I did) or just put it on your roof.

Radar estimates can be pretty meh. The rates too were so intense that it really didn't take much for some areas to flood...ground just couldn't soak it up fast enough

That's true and the more I look at the statements, it looks like it was geared more towards Urban Flooding of things like underpasses and parking lots.

That's not really a big concern up here so I always forget about that aspect of FF in the more populated areas. In fact, I'd bet a flooded underpass causes more disruptions that a few creeks getting out of their banks in a few folks backyards, so that urban flooding may even be a bigger problem than small stream flooding in terms of total impact. Especially given the time of day as folks head home from work so I could see issuing a FF Warning. There's absolutely no way any river could go into flash flooding with anything short of like 12" in 3 hours type of deal, lol.

Finally the lawn is getting a good drink, oh no, training. No complaints MBY for severe are counted on one hand in the past 10 years. Just to see these types of storms develop in the general neighborhhod and New England is enough excitement.

Feels fantastic outside now with Temp and dew dropping.

This is when the southern end of that cell past to the N and E.

Wet microburst reported in Arlington

My entire yard is pretty much protected by trees, although with the cleaning up they did in the spring the side of my house may have enough open space for me to place my rain gauge to where it's far enough away from the house and other trees.

As far as the roof goes...no access, it's a 2 family apartment with a slanted roof.

Just got home… Witnessed some interesting boundary interactions earlier today, as expected. If you look at a OKX radar loop around 18z to 19z time frame, you can see it: in southern CT a line of storms approaches a seabreeze boundary which was likely reinforced by cold outflow from earlier convection out on LI. The entire line simply blows up when it hits the boundary, becoming rather impressive very quickly. You can even see a couple of brief mesocyclone-scale spin-ups in places, one of which I observed first hand from North Haven, and which briefly produced both a wall cloud and a pretty decent funnel… But I’m hesitant to label these spin-ups true mesocyclones, because they were not persistent. The updraft I was watching collapsed almost immediately, and in fact on radar you can see the whole line collapses even faster than it blows up, an apparent casualty of the infamous marine layer. So there’s boundary magic going on in both positive and negative ways: the updrafts definitely acquire both spin and lift when they hit the boundary, but as soon as they move past it the more stable air on the other side causes them to erode and ultimately collapse. I don’t think I’ve ever seen a vigorous and organized updraft fall apart as fast as the one I was watching today did. So to recap, today in southern CT it was mesoscale boundaries FTW, but also FTL!

Clearly the main excitement today was up in MA and RI, though. Very cool stuff. What happened here in CT was just a sideshow in comparison

Well that sucks.

Look like I got the finger from Mother Nature on this whole event; convection to my north yesterday and last night, convection to my south today. Not that it was unexpected based on the poor timing of the cold front around here. Once the cold front came through during the late morning and shifted our winds NW I knew this area was done for.

I'd practically welcome another Irene with open arms at this point. :maprain:

I feel your pain! Two cells late this morning just missed most of Pepperell...nada here after 7 straight days of 90 plus. It's dry as a bone.

Damaging wind potential still looks to be high (near 60 kts) along with heavy rain. Rain RAP data on the PC here at home. Rainfall rates of 1/2-3/4 inch per hour good bet. Could see as much as locally 3-4 inches in stronger cells slower moving or where training occurs. Interaction of convection with leftover boundaries could enhance LL shear and result in brief spin ups but again I think the threat is more WIND and R+++++ now.

SW CT and extreme SE CT to RI appear to be under the gun for the strongest storms. Best DPV his (forecast) to be here. Along with this region in favorable posn wrt to H500 jet. There also appears to be a bit of transverse circulation setting up between this jet and the H850 one.

In addition some mid-lvel cooling is forecast to track across SE CT and RI along with ALL of CT to SEMA forecast to be under a -10 to -20 (2HR) dKm 500 mb height fall center,

This data is from the latest RAP (4PM) model available

Any particular timeframe? Besides lots of rumbling this afternoon and enough rain to wet the ground... It's been a complete miss down here along the sw coast of RI. Been checking the radar and quite honestly my untrained and totally uneducated meteorological eye just ain't seeing it.

Definitely ftl for me, but definitely interesting things happened to that line as it was approaching New Haven, but I could definitely tell it was taking a dump on itself once it really started heading towards the shoreline.

Seabreeze front interactions ftw, marine layer ftl.

I also looked like an idiot on facebook telling people to prepare for a crazy afternoon down here, and that didn't materialize and I started to realize it around 1:30.

Still look like a genius for warning people about the October storm, the Thursday before it happened.

Hi Tim!!

I wasted a sick day because I thought today was going to be good, now I'm pissed off.
