SNE Convective/Thunder thread

[Professional Lurker]

Just about every time I think I see a storm start to pop south of Albany in the Hudson Valley, it vanishes within a few radar scans of it's origin. What's keeping those from exploding? ...is it the lack of shear that would separate the updraft from the downdraft, so the storm just collapses upon itself?

2.75" Hail in Stratford, NY

[wxsniss]

wow... initiation certainly not a limiting factor today

RAP 0-3km EHI for this afternoon:

[TalcottWx]

84 in brockton 64 at Logan

[Typhoon Tip]

Do you know where I live?

It says CT in you avatar area... anyway, check this out

…station IOSN3, which is a buoy just ENE of Cape Ann showed a burst of E wind when that near shore front barreled on through…

Wind Direction (WDIR):

E ( 80 deg true )

Wind Speed (WSPD):

18 kts

Wind Gust (GST):

19 kts

It was only 8kts from the SE prior to this 2pm ob. I'm interested in if BOS shows an ENE yank in a short while here. Again, hi res imagery continues to show a momentum/flux from the NE underway. Could see it gust to 20kts in the Harbor waters and be a bit of a jolt to small sailing vessels. Then if it comes on shore or runs out of momentum... unsure.

Fascinating meso day here in NE with 90/70 torridity butting up against this Marine/outlfow hybrid meso high.

[Wonkis]

I wonder if they'll tor warn that cell east of Utica.

[Ed Lizard]

Even Coastal Connecticut not as badly affected by marine influence as one would think, with temps around 80ºF. I recall a lot of big storms in interior New Jersey/New York that would fizzle as they ingested cooler air off the Atlantic, but I'm not sure that is the case. New Haven is 83/71ºF...

[ChrisM]

chirs where did anyone say a marine layer would effect you?

I asked why no svr watch, was told marine air outflow. Right up there ^

[bobbutts]

3.5" hail reported (from facebook??) in Warren NY.. damn I wish that webcam I was watching was located closer to where that happened

[CT Rain]

What's the rush? Storms still hours away.

2.75" Hail in Stratford, NY

I just saw a report pop up on my GRLevel3 screen. 3.5" hail at North Bolton, Warren County, NY, kind of close to Warrensburg. That is big, big hail for New England. It was right on the path of that supercell.

I'm in Harwinton, in the nw corner where its currently 91/76 lol

PWS read too high dewpoints because they aren't properly sighted and they're located near a bunch of vegitation. There's a reason the official reporting stations are 71/72. It's not representative of the airmass, just your backard. There's a big difference in moisture between a 72 degree dewpoint and a 77 degree one.

Go through the PWS and you'll see a local maxima here and at the 3 nearest locations. Actually the PWS reports near CEF and ORE are close to the official stations. Presumably all PWS suffer from the supposed siting deficiencies... so that doesn't explain the maxima. Not to mention there's not any vegetation anywhere near the UMass station, which was carefully sited according to protocol.

[OSUmetstud]

this thread is updating slow so i couldn't quote the post....but PWSs notoriously read too high dewpoints because of a combination of lack of accuracy and not proper sitting. Even AWOS chilled mirror dewpoint sensors are +/-2 degrees F with accuracy...and then drops in the extreme ends of the spectrum. 77 degrees may be representative of your backyard but not the general airmass as a whole. There's a big moisture difference between 77 degree dewpoints and 72 degree dewpoints.

[powderfreak]

87/71 at BTV...damn that's a good SVR airmass.

Tornado Watch in effect.

[CoastalWx]

BUT BUT Tip and Scott say W CT will taint due to marine air coming from the Gulf of Maine!

What?

[ChrisM]

Truly gorgeous cu to the n

Five pws all reading 75+ dews within 5 mi

[Quincy]

Doubt CT gets the worst of it, but the timing is going to be later, be patient. I hear a lot of people downplaying this, but we could still get hit across interior western CT.

[CoastalWx]

Must suck to live in a place that's 64 and cloudy while the other places are 90 and sunny not too far away. Oh...that and the lack of snow, interesting severe, hot days. Man, a weather fan's worst nightmare.

Congrats on getting one more tstm than me.

[Baroclinic Zone]

Stick to the topic. We don't need a debate about the discrepancies between PWS and official reporting stations. Take that to another thread.

[OSUmetstud]

Five pws all reading 75+ dews within 5 mi

they're all PWSs...

[TalcottWx]

How is interior se ma cooking to the mid 80's? Weird differences all over the place.

[CoastalWx]

Those 75 dews are weenie- ish

[HoarfrostHubb]

66/63 at KFIT meh Will take a lot to get this overcast out of here and pop temps

[TheBudMan]

Picturing Paul right now downing a 40 going 100 mph in a beat up Chevy Vega getting texts about 3.5" hail as he passes through the infamous tornado town of Great Barrington.

[Typhoon Tip]

With all those storms firing in NE Pa and E NY they'd better either get a tor or STW up for the rest of interior SNE ASAP.. Wow

Not so sure...

several reasons:

-- storm motion is ENE so there isn't an immanent threat at the moment

-- synopsis doesn't support at the moment, with apparent resurgent push of marine/outlfow hybrid air mass careening into eastern NE - that air mass may actually get you guys in NE CT in 2 or 3 hours.

-- there seems to be a bit of ridge edging and CIN in the area.

Front is to the N of SE MA.

Yeah no rush for a watch for our backyard. Storms are still hours away. Still waiting for a push of height falls to scoot in here.

[Gwhizkids]

4000 j/kg MUCAPE in southern Litchfield County right now. Lots of fuel...
