weatherwiz Posted June 21, 2015 Author Share Posted June 21, 2015 Yeah the pieces are all there... Now we need them to come together. Can be tough to do. Well you probably need to wait another day to be sure. Details like any debris or EML coverage just need more time to sort out. The wind fields regardless are impressive though. Agreed...at this juncture the pieces continue to remain on the models, in some cases even becoming a bit more eye opening but now we're onto the toughest task...getting everything to align and fall in place. This is what usually ends up killing us here...we do get the pieces but not very often do they all come together. In some instances, part of this setup looks even more impressive than 6/1/11 as far as some of the numbers go and parameters go which is quite impressive to see.

weatherwiz Posted June 21, 2015 Author Share Posted June 21, 2015 09z SREF pops a 60 sig-tor ingredient contour in west-central MA at 18z Tuesday. What I find extremely impressive is the 50% probs of effective bulk shear...that is pretty mind blowing. Not just bulk shear but effective. That's some serious stuff...especially if you're looking at the possibility of >2000 J/KG of MLcape. Link to comment Share on other sites More sharing options...

weatherwiz Posted June 21, 2015 Author Share Posted June 21, 2015 NAM and GFS have backed off a bit on directional shear but still spitting high helicity b/c there is a degree of turning in the lowest km and strong speed shear Link to comment Share on other sites More sharing options...
Tornado Girl Posted June 21, 2015 Share Posted June 21, 2015 Here's a tease sounding at ORH from the 00z NAM valid 21z Tuesday. I was wondering how you got this sounding from the SPC....I can only get the current run....not ones like this going out a few days..... Link to comment Share on other sites More sharing options...

That's some serious stuff...especially if you're looking at the possibility of >2000 J/KG of MLcape. Did a write up on my website concerning the possibilities. Looks like severe weather potential for sure, over a widespread area. http://weather.st/blog/northeast-wx-watching-tuesday-623/ About the best I can do with the information provided by soundings and charts. then again we are looking at things via NAM perspective...

CT Rain Posted June 21, 2015 Share Posted June 21, 2015 Just looked at the 12z NAM/GFS/SREF. Continues to be very impressive for Tuesday. It's pretty unusual to throw around a few thousand joules of CAPE with 50 knots of effective bulk shear. LCLs look a bit high for tornadoes but we'll see.

jbenedet Posted June 21, 2015 Share Posted June 21, 2015 Any word on potential BRN's? A lot of shear can be too much of a good thing if you don't have the CAPE to support it. Areas closer to the Surface LP in Northern upstate NY and Northern VT/NH will likely suffer because of it--BRN's will likely be very low... Areas further south will have the best chance for super-cells in my opinion. I like a swath from Albany through Central Mass up into southern VT and southern NH, where shear and CAPE levels, in combination, will be constructive to severe t-storm development and lifespan. That's just a best guess at this point obviously... Link to comment Share on other sites More sharing options...

That's just a best guess at this point obviously... I looked at that earlier...they were running a bit low up here on the forecast soundings. The NAM was under 10 which is a sign of too much shear which is why I wasn't too concerned when Wiz said the models lost a bit of shear. We'll see...usually that's with low CAPE situations and this time around we have most spots flirting with a couple thousand joules. EHIs are pretty high.

Typhoon Tip Posted June 21, 2015 Share Posted June 21, 2015 I think of LCL component as important for swarming at smaller intensities... usually when the LCLs are low you are so heavy in moisture that it breaks earlier in the sounding. The better is mid ranged LCLs (from what I've seen..) because we've 'built up' CAPE prior to breaking through and you get those stove pipe jobs. When I see this, ...like so many other violent tor of lore, they are not always garland by the collar of tree top kissing mesos... Some are though, sure. That big Oklahoma one of 1999 appeared to either be enveloped in a meso that came all the way down, or one helluva spectacular debris ball!! Re the set up, I'm too lazy to delete and paste over my thoughts n this. I'll just paraphrase: Watch for pre-frontal heat/trough, not uncommon in this sort of set up. Those will tend to back the wind westerlies over western zones (killing their 0-3 km shear), while veering more S over central eastern areas. Storms could fire premature to best deep layer mechanics arriving, exploiting CAPE ...and then altogether it acts like a 'dry line' and whisks early thunderstorms and the best theta-e right on out to sea. Not sure what makes that set up more likely over others, but back in 2011 and 1987 ... etc, the best events from my experience around SNE is always morning convection associated with warm front or diffuse warm front, then searing sun in broiling sweat pushing humidity wafts in right before big discrete right movers/MCS sets up in central and eastern NY and roar(s) down the Mohawk Trail ...

andyhb Posted June 21, 2015 Share Posted June 21, 2015 If you notice with a lot of the more notable late spring/summer SNE threats, the day before often targets MI as tomorrow will. This is a more classic setup for getting a decent lapse rate plume east. Link to comment Share on other sites More sharing options...

andyhb Posted June 21, 2015 Share Posted June 21, 2015 7/3/97 and 6/1/11 (was a moderate risk in MI on 5/31) are other prime examples of this. Looking at the mid levels specifically, this setup carries a number of similarities to both of those. Link to comment Share on other sites More sharing options...

This is a more classic setup for getting a decent lapse rate plume east. This was my immediate thought yesterday morning when I saw the SPC outlook for Monday's "Enhanced" across Michigan. Our best events often smoke Michigan the day before.....see: Flint, Michigan tornado. Link to comment Share on other sites More sharing options...
