CoastalWx Posted July 19, 2016 Share Posted July 19, 2016 Looks like some sort of microburst about 1 mile from my house and into Hingham. Link to comment Share on other sites More sharing options...

Hildy Posted July 19, 2016 Share Posted July 19, 2016 Here are a few from Wellesley, which was a macroburst. The Dana Hall School area was particularly hard it--at least 10 trees down on the campus. Sorry for the links instead of images--I resized the photos and they still won't let me upload them. Dana Hall 1 Dana Hall 2 Dana Hall 3 Link to comment Share on other sites More sharing options...
Typhoon Tip Posted July 19, 2016 Share Posted July 19, 2016 some kind of freak show tornado SSE of DES IA... saw a stationary couplet that was about half the size of the state or RI, gated at over 90 kts... wonder what that was all about - Link to comment Share on other sites More sharing options...
OceanStWx Posted July 19, 2016 Share Posted July 19, 2016 Casual supercell passing just north of CAR yesterday. How's that for New England structure. Link to comment Share on other sites More sharing options...

It's like a 30 foot wide swath. I think it was the police or fire chief offered up his drone to our survey crew today. I would need consultation from Tamarack about tree dynamics, but this kind of a channeling is not uncommon. One tree goes down, and allows the wind to accelerate into the channel and take other trees down. Link to comment Share on other sites More sharing options...

Obviously need to work out the mesoscale details but you've gotta like the look this far out. Link to comment Share on other sites More sharing options...

Didn't even look for that...was looking more during the afternoon hours. I hope we do see steep lapse rates though, the last few setups the GFS had decent lapse rates but that never really happened...even the other day 700-500 were less than 6 per mesoanalysis but GFS had been showing around 6.5 Link to comment Share on other sites More sharing options...

With NW flow and good lapse rates these events tend to have some longevity - even after 00z. Pretty close to going from 6 to midnight here. 7 C/km lapse rates, NW flow with a nice jet core punching in at prime time, low level theta-e lapse rates pushing 10 K/km. A lot to like.

I can tell AWIPS to do the math for me, but I don't know of many website that explicitly even show single level theta-e. weather.cod.edu does have theta-e up through 850 mb though.

powderfreak Posted July 21, 2016 Share Posted July 21, 2016 Nice AFD from BTV on the situation... I like the "uncommon" to see SPC Slight Risk at Day 3. .SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/... As of 320 PM EDT Wednesday...An active period with several rounds of strong to severe storms possible. Thu Ngt/Early Fri Morning: A surface front in Ontario/Northern Great Lakes will be slowly approaching. Deep low-level layered moisture with with PWATS >1.5 inches advecting ahead of front...instability aloft with increasing presence of elevated mixed layer...a shortwave trough and exit region of 300mb jet approaching should have mesoscale convective complex in northern Great Lakes/Ontario moving into FA during late Thursday night/early Friday morning. Friday: As advertised...an Interesting day. SPC Day 3 (issued earlier today) is uncommon across FA. At times during the past few days models suggested that various ingredients didn`t quite come together all at the same time especially an elevated mixed layer. However...latest guidance is showing potential elevated mixed layer being present thus helps support the other parameters that have already been discussed in previous discussions. Surface instability (temperatures well into the 80s, resulting in CAPE values pushing 2000 J/kg. there still remains some questions on the low-level instability due to previous convection or debris clouds stabilizing atmosphere but feel enough dry air aloft and breaks will allow for substantial recoup of llvl instability. A shortwave skip through at some point during the day. Deep WNW shear of 35-45kts along with model soundings also indicate high equilibrium levels and semi-low wet bulb zero (10-11k ft) levels which suggest a wind and hail threat. Timing...After some recoup time from early morning activity...llvl destabilization and upper level shortwave activity in late morning/ aftn for some activity and perhaps enough drying afterwards for more late aftn/evening with surface front and another shortwave. Then we have a possible threat on Monday as well: Very similar Monday to Friday`s set-up with approach of strong shortwave...strong wind dynamics...a bit more amplified and stronger surface cold front with decent cold air advection and falling heights associated with it. Strong to severe storms possible again and already some mention in SPC Day 4-8 discussion. Link to comment Share on other sites More sharing options...
