Damage In Tolland Posted August 26, 2020 Share Posted August 26, 2020 A high end severe weather event is possible with damaging wind and large hail. Warm fronts are always dangerous in these environments as they provide a source for enhanced low level shear so a tornado or two is also possible. The CAMs indicate that discrete storms may eventually evolve into multicellular line segments. The greatest risk appears to be in northern CT and SW MA where HREF is suggesting robust updraft helicity probs. Link to comment Share on other sites More sharing options...
CoastalWx Posted August 26, 2020 Share Posted August 26, 2020 It’s close. Nam would be more south. Would rather see front in NH. Link to comment Share on other sites More sharing options...

CoastalWx Posted August 26, 2020 Share Posted August 26, 2020 It's a good look, but you need to keep an eye where the WF is. Technically it doesn't even sector Tolland. But SW CT looks good. Link to comment Share on other sites More sharing options...

Not sure I can remember such rapid WAA and rapid destabilization like it shows. Didn't that happen 5/31/98? Anyways...not sure how it translates to here but I know out west in those scenarios tend to lead to significant events...and rapid fire too. such rapid WAA an destabilization just yields such vigorous upward vertical motion...which also can be a factor with increasing SRH.

weatherwiz Posted August 26, 2020 Author Share Posted August 26, 2020 I am not the *biggest* fan of this product...I think it places too much emphasis on shear (especially in high shear/low CAPE setups) but values of 30-45 are pretty damn impressive for up here 2 Link to comment Share on other sites More sharing options...

Typhoon Tip Posted August 26, 2020 Share Posted August 26, 2020 11 hours ago, Typhoon Tip said: All three days Thursday through Saturday look troublesome or certainly could turn out that way with that front oscillating in the area ... accentuated helictites long it with unusual thermal gradient for this time of the year either side is intriguing. Seems that EOF1swarm idea had shifted more to Saturday with organized cyclone mechanics in the area but the boundary itself could be active for a couple days before that ...wherever ultimately sets up And Saturday looks really bad to me on the 00z Euro... In fact, the behavior of the pressure pattern and QPF matches climo typology for tornadic events over eastern NY the upper MA and interior SNE ... with a pretty clearly define morning straif of elevated convection along a warm front strongly supported by synoptic detailing, giving way to warm sector intrusion to lower VT/NH ... and along the residual warm frontal axis arcing into upstate NY there are very intense convective nodes exploding in the model resolution of what happens next... Those are super cells folks - no question given the W 70-90 kt 500 mb flow running collocated overtop a sun steamed, fresh theta-e transported low level thermal ridge ( 850s 20 C CT over SE Massachusetts!), and heights tending to fall overtop from west to east across the area between 18z and 00z Sunday... The key is.. warm intrusion and fresh falls of BL rains near 12z clears out and this creates a pal of SB CAPE anomaly in the area...if we go back and look at the daily behavior prior to '89, Monson 2010, even ORH '53 ...and the Mohawk Trail MCS June 10 '87 ...these are all fine examples of what to look for and were remarkably similar with dawn rumble rains that peeled away and sun-soared to mid 80s/72 blue-tinted bath water hillsides ... ensuing jet mechanics nosing in mid day from the west... That's Saturday incarnate - I mean Oklahomans might feel jealous looking at these general synoptic parameters. Devil's in the details with convection though ...so, this is just what I've gleaned off Pivotal - there may be distractions I'm not seeing or are unaware therein but ... it's like Thursday and Friday have their intrigue, but Saturday was painted with unique convergence of parameters constructing a convective appeal on a guidance that is very tough to beat at time ranges < 120 hours. I would change the title to three days of potential and just encapsulate the whole saga - 1 Link to comment Share on other sites More sharing options...

I should be able to "chase" tomorrow...by chasing I mean sit at BDL (that's my goal). Or maybe go towards SW CT depending on how it looks. But I don't think I'll be going out-of-state with all the quarantine guidelines in place...although NY and MA aren't on the list but still.

I think it was still a slight...for moderate I think you needed 45% wind (or 30% hatched)...I think hail too but maybe it was 30% for hail and 10% for TOR. But given this is a day 2 outlook b/c the 30% wind is hatched that may have qualified for a moderate...I forget. 1 1 Link to comment Share on other sites More sharing options...

Sure doesn’t “feel” like it in a bushman's vision ...that's why though. This is anomalous air mass for seasonal change... It's not even a preview ( 'shot across the bow') really ...strikes me as a fluke. I like shot across the bow, breaking back air masses to be anchored in a definitive pattern modulation... This is a weird thing that I think is related to another popsicle headache... Anyway, 18 hours later summer tries to surge back, and homage to the idea that it's still there... And that's a problem ...when you have still active moisture draining off foliage and evaporation of soil moisture content in the midwest and Lakes regions .. mixing with tumbling 17+C 850 mb temperatures ready to surge right back in, this unusualness of the severe set up for this time of year...is sort of indicative of this 18 to 24 hour fluke air mass... Correct one way, snap back - It's really difficult up our way too...because our topography/geographical feed backs offer more forcing that stall or even reverse warm fronts. Basically, because the land falls out in elevation from underneath the troposphere when east of NY/VT/NH. Vectors lifting over the western hills/mountains and general higher elevation, sets up a kind of "invisible" counter-vector that rolls the atmosphere and tacks back W-S at lower levels east of said axis... There's a forcing back SW... at all time below 800 or so mb. This is why BDs seem to get pulled back down the coast...it's more than just the mass discontinuity ...That's the start, but that motion of air then gets a kick-back from that tacked vector and then the boundary over achieves... it's why in late April, a common almost fixture of fronts stalled in the area is that fronts align smartly due E until about Albany, then curvilinearly descend SE and wrap around NE and even go back N over the water E of Cape Cod... It's that rolling motion that retarding. It's also why we "tuck" in the winter and enjoy ice storms while PF in N. VT is 52 F at mid slope. 1 Link to comment Share on other sites More sharing options...
