OceanStWx Posted June 18, 2018 Share Posted June 18, 2018 8 minutes ago, weatherwiz said: Here's a question I've always had but never found an answer. On bufkit in the hodograph section, on the bottom left of the hodograph there is an output for Cape and Helicity...does anyone know what level the Cape is measured in? is it surfaced-based (I'm guessing it is not sfc-based output) mixed-layer, or most-unstable? If i had to guess I would guess mixed-layer. I even tried playing with the llc values on the right to see if that would adjust Cape values but it only does so with helicity I believe it is outputting CAPE in the same layer you are calculating shear. So if you have 0-6 selected, it's CAPE in that layer. Link to comment Share on other sites More sharing options...
weatherwiz Posted June 18, 2018 Author Share Posted June 18, 2018 I don't think its the warm front but there looks to be ome sort of boundary that runs from around ALB into MA down into northern CT Link to comment Share on other sites More sharing options...

Unless for some odd reason it's the same CAPE values at each level lol. I'll try a different model too...was just using the 15z HRRR for BDL Link to comment Share on other sites More sharing options...
weatherwiz Posted June 18, 2018 Author Share Posted June 18, 2018 This sucks...my camcorder's dead and i can't find my charger. I won't have time after work either to go buy one and then get to BDL from Branford before the storms come Maybe I'll just go to a golf course in WeHa or something.

Just a few embedded strong-to-severe thunderstorms (particularly west and north-central CT). We have stronger flow working in aloft, decent height falls, the instability.

Head to NW Mass the HRRR, NAM Nest, and RPM all been pretty consistent with a line (perhaps broken) moving through the state. Best chance for any severe is certainly up around NW MA though but I definitely won't make it there. I might not even be able to make it to BDL b/c traffic from HFD to BDL at 6:00 when I get into HFD area will be horrific. Unless I take back roads from WeHa to Bloomfield and catch 91 there Link to comment Share on other sites More sharing options...
PowderBeard Posted June 18, 2018 Share Posted June 18, 2018 Hot and humid in the Valley but a nice 15-20mph breeze is making batting practice bearable. I don't remember such a breeze on days when we got into some good storms. Link to comment Share on other sites More sharing options...
weatherwiz Posted June 18, 2018 Author Share Posted June 18, 2018 RAP/HRRR continue to really suggest enlarging hodographs as we move into the evening as stronger winds aloft move in. Also looks like a surge of higher theta-e air moving into western areas with a push of higher low-level moisture. that could help keep instability up there even for a few hours after sunset. Too bad lapse rates are awful but if some cell can get some updraft enhancement it will have lots to work with. Link to comment Share on other sites More sharing options...

OceanStWx Posted June 18, 2018 Share Posted June 18, 2018 With moist low levels and steep low level lapse rates, you do get buoyancy in those lower levels for stretching/mix down potential. So while mid level lapse rates would be nice, we don't need 40+ kft towers for strong storms today. Link to comment Share on other sites More sharing options...

It's really becoming quite intriguing, especially when you take into account the consistency hi-res models have on activity moving into the state...this coincides with combination of best shear/instability (well maybe weakening instability but still sufficient). 4 minutes ago, OceanStWx said: With moist low levels and steep low level lapse rates, you do get buoyancy in those lower levels for stretching/mix down potential.

Yeah good point...these low-level lapse rates are quite steep so won't take much for strong wind gusts. Even some Td's of 71-73 not far SW...that alone will help compensate a bit for crappy mid-level lapse rates. Link to comment Share on other sites More sharing options...

tamarack Posted June 18, 2018 Share Posted June 18, 2018 TOR warning for Lincoln, NH and environs - storm looks to be coming straight down Rt 116 from Kinsman's Notch. Would losing 1,000+ ft elev in a dozen miles keep a funnel from touching ground, or have no effect? Nice line of showers moving into central Maine from the mts, though all the pretty colors separated and went N & S of the home front - doubt if we got more than a tenth or so.
