CT Valley Snowman Posted August 8, 2018 Share Posted August 8, 2018 Oops. Box's tweet around 5 P.M. NWS BostonVerified account @NWSBoston 5h5 hours ago More [Evening Update] given temperatures are not rapidly (less than 6C/KM) decreasing with height aloft & vertical wind shear is weak (less than 20 kt), #thunderstorms will weaken with sunset and NOT persist overnight. Thus drying trend as the evening progresses. #MA #RI #CT Link to comment Share on other sites More sharing options...
CT Valley Snowman Posted August 8, 2018 Share Posted August 8, 2018 Storms do finally seem to be weakening now but that tweet gave the impression we would be in the clear by 8 or 9 at the latest.

Going back beyond that you'll probably have to sift through a combination of Storm Data, and things like the Grazulis book on significant tornadoes. Thank you for the information.

So many close strikes earlier, house rattling piercing type thunder and just prolific lightning both in cloud and cloud to ground. Power off an on several times. It's been one hell of a stormy night. Other circles of friends have been responding similar wrt to yesterday's activity. And, I saw some of that myself. I had constant flickers in the activity as it neared northern Middlesex Co here in N. central Mass around 6:45 pm. The thunder was softly crackling but was always doing so... with these overlapping "flicklets" ... Then, every so often, a more ominous low decibel reverberation loomed up from the horizon. Comparing yesterday with other days with thunderstorm activity so far this summer, most of the previous have been pedestrian lightning producers, and/or even sans lightning. There were loaded rain and at times ... outflow producers, but it's not been a crazy lightning strobe summer. My hunch is that has something to do with glaciation altitudes in the atmosphere. Previous events were taking place at 585+ DAM, with thickness up into the mid 570s... That means you have very tall atmosphere during those events - think ... heating a balloon. The gas inside expands and the balloon grows... But, for the purpose here, when you get these swelled up atmospheres, the glaciation levels tend to be rather high - or some anomaly therein. Usually..., that is. You can get transient scenarios where the glaciation heights are plummeting over top of an elevated thickness column, and then ...well, you get more lightning that way. Or, you get more lightning any time you have more mass suspended in that ice layer of the CB total structure. There's on-going research ...right down to quantum scales actually, that attempts to plumb the mysteries of lightning. I actually read one peer-reviewed and accepted paper that hypothesized cosmic rays as playing a critical role in triggering the discharges, as the polarity in-cloud is technically not enough to really overcome the ohm distribution of free air, such that the cosmic rays bombard the electrons and give them the final kick that cascades the discharge. Excluding those exotic ideas .. the 101 classical hypothesis is that cloud morphology causes huge polarization (there are competing theories on what those physics are ..of course) of particulates suspended in those altitudes... By the time the ice in the glaciated mass gets to that state, it is by process made to be very positively charged, for which ever and whatever process aside. This is differential relative to the bottom of the cloud ... which in its self disparate to the surface of the Earth. Pretty sure the model is + - + between Anvil and Earth. Given that model, ...it's logical to assume that the more mass passing through phase change toward glaciation/ice would enhance the electrical field/gradation, thus easier to attain the 4X10^2 volts/M^2 that is needed to overcome atmospheric resistance and ionize a channel for the discharges. ... one can/should check that number. It's just an extension of the above line of reasoning ... thicker bulbous anvil plumes fire off bolts in every direction ...compared to these partial glaciation cores that may have 55 to 60 dbz chicken-drowning warm rains As an after thought ... today may sport more of that crackle fest.

tamarack Posted August 8, 2018 Share Posted August 8, 2018 After a sticky day with abundant deerflies in the woods of eastern Maine, I played "TS tag" for about 50 miles between BGR and Skowhegan. Each turn in the road put the darkest/rainiest areas south/centered/north of where I was headed. Finally caught up to warned TS between Skowhegan and Norridgwock, though north fringes only, saw sizable puddles within 3 miles of home, only "T" in the gauge. Maybe next time. (Though svr TS have hit within 10 miles in all directions dozens of times in my 20+ years here, only a 30-second gust in June 2005 that may or may not have reached 60 mph came close to svr at home.)

Typhoon Tip Posted August 8, 2018 Share Posted August 8, 2018 SPC expanded their Mrgl region to encompass much of the region ... S of Maine.. I just had one of those single pixel, 10 second jungle drop rain showers. These slow moving narrow cores are funny like that. No thunder... and the cloud base is no broader than a single neighborhood. So... regional DPs appear to be a tick or two richer today, though the temperatures are a few less oppressive... Not sure what that swap-out means for SBCAPE. Given to CU field morphology I'd have to argue that mid llv heights are more inviting updrafts today - but there may not be as many triggers/mechanics for sustaining Link to comment Share on other sites More sharing options...

I have Grazulis' 30 page "New England Tornadoes" pamphlet, wonder if that's worth anything? Actually I'm sure it isn't, I got it for free way back when I bought the Tornado Video Classic tapes, but it's actually very useful, has entries on every New England tornado going all the way back to the 1700s (it stops at 2000 when it was written), plus some track maps which are pretty cool.

Every office I've worked at has had it in the library (ours is the version to 1991, but post 1950 tornadoes are relatively easy to get at). The depth of research to get all significant tornadoes (and those including fatalities) is amazing, and the reason he can command that money. Quote 7/4/1898 1530 3k 120 inj 1007 1 m F1 Hampton, NH A tornado moved SE across the resort community of Hampton Beach. Three people were killed by falling timbers in a skating rink where over 100 people had taken shelter from a thunderstorm. Twenty cottages were torn apart. Five people drowned as a yacht overturned, but those deaths may have been caused by peripheral microburst winds. No one at the beach, in the panic, noticed a funnel. However, form a distance, one observer saw the tornado and thought that there was a fire at the beach. Link to comment Share on other sites More sharing options...
