DomNH Posted July 7, 2013 Share Posted July 7, 2013 Wiz must have been too far south? Broken utility pole at Whetten Rd and Albany Ave #WestHartford. Whetten has many trees down. pic.twitter.com/hGxxPOpAdu Retweeted by Ryan Hanrahan I was in Middletown and the towers from that storm were seriously impressive. Wish I got pictures.

CT Rain Posted July 7, 2013 Author Share Posted July 7, 2013 It's just so hard to get large hail with such warm temps aloft. You have a warm layer nearly 15,000 feet deep and it's just moist throughout. So you don't even get the evaporational cooling assist to keep hailstones from melting as they fall. Yeah you can have a giant hail dual pol sig and a fat TBSS and get stuck with dimes at the ground. I loved a lot of the dual pol training on hail from WDTB but there are so many more variables that go into "slam dunk svr hail" in this part of the country.

Yeah I was driving back from Glastonbury on Rt 2 toward Hartford and it was a really neat looking storm from up close. Link to comment Share on other sites More sharing options...

I loved a lot of the dual pol training on hail from WDTB but there are so many more variables that go into "slam dunk svr hail" in this part of the country. With dual-pol and super res data, we're seeing a lot more TBSSs than we used to. So it's a work in process to recalibrate which ones are indicative of severe hail and which are just a bunch of wet half inch hail. Link to comment Share on other sites More sharing options...

So it's a work in process to recalibrate which ones are indicative of severe hail and which are just a bunch of wet half inch hail. Yeah there are a lot of 1 radial TBSSs that are sort of meh... but the monster ones spanning a bunch of radials still seem pretty good indicators. That said... height of TBSS and the profile (i.e. deep/moist adiabatic below the TBSS) probably makes a big difference. I would like to see some nice New England research now with dual pol/super res about hail size with new products available. At the end of the day... things like BWERs/strong storm top divergence/strong mid level mesos are still pretty good proxys for which storms are legit and which ones are dead tree branch/exaggerated peas.

The last couple of days have still been a little surprising. 50 dBZ heights over 40 kft and still not getting severe hail reports, or just barely squeezing out 1".

Typhoon Tip Posted July 7, 2013 Share Posted July 7, 2013 But maybe that's a reporting bias? I think it atones to very high heights/thickness... Wet bulb 0 is anomalously high, too high up for pulse cells to produce big hail. Need a supercell to sustain an updraft and produce larger stones that way.

OceanStWx Posted July 7, 2013 Share Posted July 7, 2013 or going over areas where nobody lives lol Well that's what I mean by reporting bias. Phones don't ring so nothing happened. Yet if you make a few phone calls all of a sudden you find severe hail. Link to comment Share on other sites More sharing options...

There have been a few times I've even found 1'' or even larger just from calling like a gas station lol. Link to comment Share on other sites More sharing options...

CT Rain Posted July 7, 2013 Author Share Posted July 7, 2013 I pulled off a "where people live" dew point of 79F this morning at 1030 and a peak "where people live" heat index of 111F at 230 pm. Link to comment Share on other sites More sharing options...
OceanStWx Posted July 7, 2013 Share Posted July 7, 2013 LAter on could be a bit interesting with that stuff heading in from PA...models keep it very unstable and vertical shear increases as well. It seems that models want to key on western SNE into southern NH for that remnant MCV to track, continuing thunderstorms there. That could put down some heavy rainfall, ahead of more expected tomorrow. Link to comment Share on other sites More sharing options...

Have to think this stuff holds and we see even a threat for an isolated strong to severe storm tonight across western sections. Some spots between tonight and tomorrow though are going to see quite some rain totals. Link to comment Share on other sites More sharing options...

Some spots between tonight and tomorrow though are going to see quite some rain totals. Given the poor lapse rates (most of the area has been worked over so to speak) I wouldn't expect severe, but given the 2000 J/kg MUCAPE I could see a really nice light show for somebody. Along with heavy rain of course. Edit: Now seeing some spots of 3000 across SNE (via RAPv2 mesoanalysis). Link to comment Share on other sites More sharing options...
