Torch Tiger Posted 7 hours ago Share Posted 7 hours ago 20 minutes ago, vortex95 said: I will say this event was rather impressive given the slightly anticyclonic flow aloft. Usually w/ such hot temps and that kind of flow aloft, it remains capped. One thing though the cell coverage did to rage into a SQLN at first. Cells were small clusters but intense. mesos were so-so, but you could see how a very solid event could get going along I-90 ish Link to comment Share on other sites More sharing options...

I also noticed storms took off once they hit S coast seabreeze. Link to comment Share on other sites More sharing options...

Chrisrotary12 Posted 35 minutes ago Share Posted 35 minutes ago 7 hours ago, vortex95 said: I may have mentioned this before, but there is something physical about the NH seacoast that make tstms better or intensify here. Today was no exception, and two waves back-to-back! Isles of Shoals gusted to 63 mph. I realized this anecdotally as a kid being at Hampton Beach on vacation each summer, but that can have bias b/c everything is larger than life when you are kid, and any beach view is going to look more impressive overall for storms. Once the SPC hourly mesoanalysis product came out, I started to watch closely. What seems to be a factor is that there is at times locally higher 0-1 or 3 km shear/helicity on or just off the NH coast. Despite the cool ocean temps, a sea breeze here appears to result in intensification of storms in the area. Not necessarily svr, but a line of showers suddenly becomes active w/ CGs and weak mesos form, as one example. I've seen too many times for it to be just coincidence. What may be happening is this - first, once you get to the MA/NH border, any marine stabilization from S of SW winds coming S of LI basically becomes a non-factor. Second, and most importantly, the low-level winds over Cape Ann are briefly lessened, then pick up again once over the ocean, only to slow again once reaching the ME coast. So this sets up locally better low-level shear/helicity profile for cells to feed off of. For years, I have informally called it "The Hampton Effect." One of most outstanding example was on May 21, 2006. A nasty bowing squall line was ripping across central/southern New England. Once the northern part of the line got E of ASH, it gusted out enough that the leading edge cells weakened considerably, so there was nothing but RW-/RW and a bit of thunder. Once that outflow got to I-95, an isolated supercell developed very quickly and produced tornado at Hampton Falls. Lasted only about 30 sec, but it was clearly visible as a stout narrow column. See story here:https://www.timesargus.com/news/weather-service-confirms-tornado-hit-coastal-n-h/article_ed848d36-9e43-5117-aae8-97098039f6ab.html A waterspout also occurred not far offshore from Rye Beach. When I saw this and the radar loop, I said, "you've GOT to be kidding me, since when in New England does a tornadic supercell form on a edge of a gust from from a decaying squall line?!" And SSTs on the NH coast are still pretty cold in mid-May, yet that did not impede things at all. I think the only other time I was flabbergasted like this was the two mini-supercell tornadoes occurred in the Brunswick ME area on Thanksgiving in 2005. This was after a couple of inches of snow has just fallen here in the previous several hours! Thank you for this. I noticed the Hampton Effect a few years back after a buddy moved to Dover and he cashed every thunderstorm while ASH consistently gets nothing. I’ve been obsessed with it since because it is so consistent. 1 Link to comment Share on other sites More sharing options...

jbenedet Posted 2 minutes ago Share Posted 2 minutes ago The persistence continues with often world’s apart differences in sensible weather between here and eastern Long Island.
