15z RRFS shows the classic "cell ahead of line" near RUT. 15z HRRR looks somewhat better that prev runs for the SQLN holding on better farther E.

Definitely a CoastalWx switch I see. He is leaning more towards having a PT in the warm season w/ time and all the wx phenomena that comes w/ that!

The Cape Cod CONS LTG. I am pretty sure it was from a second wave after the 3 tornadic supercells in the afternoon. A few years ago, high quality photos surfaced taken from central MA showing local damage and also showed a very crisp and impressive CB in the distance to the E close to sunset. So that would jibe w/ the Cape Cod LTG.

And WxWiz would pass out from Xtreme ecstasy!

At least Weymouth got about 6". Enough for Scott to "break the 6" drought" and it look "VIOLENTLY BEAUTIFUL" out there! LOL.

I am not sure. A warm front passed early in the day, so that would mean RW/TRW were likely. In the afternoon, it was three distinct supercells, one in NH and two in MA. Then I think w/ the actual cold front there were few more severe storms, based on photos near sunset that showed crisp CBs on the horizon well the E of Rutland MA. Warm front passages in the morning w/ RW/TRW occurred both on 7/10/1989 and 6/1/2011.

The lawns in Weymouth will be thankful.

Ok. I haven't looked in detail satellite loop for 10/3/1979. On 7/10/1989, sunrise in ern MA was clear and cool (60 F). Warm front tstms moved through by mid-morning, and then it stayed high OVC after in the warm sector.

Two things that seem to work very well when El Nino is very strong. 1) The CONUS has a mild winter overall. and 2) the Atlantic is suppressed for TCs. This is one of the few truly long range forecasts (months) that actually have a high success rate!

Yes, the was some sun I bet in CT, but mostly cloudy overall in SNE. I noted that day in Woburn it was breezy and a thick high OVC by early afternoon. I went up to U Lowell to monitor the radar, and then noted the monster cell W of ALB. My drive from Lowell to HFD was OVC the entire time. Did not make it to HVN in time and I was just ahead of the MA tornadic supercell moving SE from Hubbardston, but I had no idea there was tornadic there (it formed rapidly after I left Lowell) b/c the VIS sucked! Even though in the HFD area missed the monster supercell, other cells hit the area, and one a drove though, I have never seen it get so dark approaching any storm in New England. The LTG was not crazy, but did it pour!

CoastalWx "mad" b/c the SLGT stops just short of Weymouth! LOL.

Oct 1979 was an odd duck. Not sure of the left movement as a factor. Maybe more CT Valley localized SRH enhancement and pure dynamics. It was right at the triple point occlusion, almost a like light version of the 1925 Tri-State Tor when the supercell followed closely the sfc low. This also occurred in NC/SC on 3/28/1984. Supercell was closely associated w/ a 980 mb sfc low and produced 15 tors, 7 that were F4! Reanalysis fcst using hires models presented at the SNE conference in ORH some 20 years ago noted that nothing stood out as any real tor potential for the 10/3/1979 event. It was the only tor and supercell, and no other svr wx reports in SNE that day outside that one cell. They also did reanalysis of 6/9/1953, and of course that stood out no problem. The BDL tor did $250M in damages. Adjusted for inflation, that would be $1.1B today. That makes it the costliest tor in New England history. At the time, the BDL F4 was the third costliest U.S. tor on record w/ the $400M at #1 from the SPS F4 in April that year and #2 Xenia OH F5 in April 1974. ORH tor in 1953 adjusted for inflation would be $658M, but in the 1953, the $53M in damages was the costliest U.S. tor up to that time.

You mean "right-moving!"

July 10, 1989, virtually no sun in SNE after late morning from a thick high OVC. Didn't matter. BDL went from 68 to 86 no problem and a 10 deg DP rise into the 70s almost all on advection once the warm front passed. A kiddie Scott had no idea a spinner would occur in Brockton that day!

Scott shying away from his winter weenie passion?

Wow, great report. Were you there at home when it passed? Could you see the funnel? Aprox time?

Hence "CoastalWx!?"

Scott uses the TBOS FAA radar for local wind insights. The pride of Weymouth - having a radar! LOL.

Sun could be interesting. Ydy it acted more like a BDF and cool marine infested, but tdy not at all. BDF in a classic sense occurs when it is anticyclonic NW flow here w/ high heights/thickness, and the only cool air is very shallow. Not the case here at all. It is cyclonic flow aloft w/ falling heights and a decent vort/shortwave moving in Sun aftn. GFS/ECM show half-decent CAPE and w/ the cold 500 temps and dynamic support, could be good in some areas. Not honkin' svr, but I bet good enough for WxWiz! The front sagging just to S may actually help in this case. Also, cells dropping N to S? They tend to do well.

Yes, and ASOS is as well. Recall it was noted that whatever falls in the ASOS gauge and melts as LEQ, can't be adjusted? So the 37.9" at PVD in the Feb storm had only 1.78" LEQ. That seems high the 21:1 ratio. BOS is much worse. 17.1" and only .47" LEQ for that storm? PVD -5", ORH -3.5", BDL -2.5" CON -2". So the -7.5" at BOS does not fit. And we are talking the first 5 months of the year where you do not have higher local differences from convection. But the media doesn't care, they just take thing as face value and run w/ it.

WxWiz wants a repeat of this! https://www.weather.gov/aly/derecho1995

Sat looking good. WxWiz needs the the tstm "hit!" And then Scott "Ossipee" hailers moving N-S on Sun. Can't get rid of these cold 500 troughs rotating through and the blocking. If the 00z ECMWF is correct, after Sat, no sig heat or dew point (gin and) juice UFN for eastern sections.

Oh, and WxWiz will like this, there were likely several spinners in SE MA and RI for Gloria, in addition to the one confirmed in Billerica MA. Look at the PNS from WSO PVD issued 3 days after Gloria (the bulletin is cut/pasted as is - typos are real). TTAA00 KPVD 301506 NATIONAL WEATHER SERVICE BOSTON MA 1100 AM EDT MON SEP 30 1985 THERE HAVE BEEN SEVERAL REPORTS OF TORNADOS ASSOCIATED WITH HURRICANE GLORIA IN THE AREA ON FRIDAY SEPTEMBER 27. 1. LOCAL POLICE IN SEEKONK MA REPORTED A TORNADO HAVING OCCURRED AT PINE STREET ON THE REHOBOTH-SEEKONK MA LINE AT APPROXIMATELY 230 PM EDT. 2. A CHARLES CINTOLO IN GLOUCESTER RI REPORTED A TORNADO IN THAT AREA. 3. REPORTER FROM THE PROVIDENCE JOURNAL STATED THAT SHE RECEIVED TWO REPORTS OF TORNADOS: A. NEAR THE BURLINGAME STATE FOREST IN CHARLESTOWN RI. B. NEAR A GOLF COURSE IN W. KINGSTOWN RI. OUTSIDE THE AREA TWEKSBURY MA REPORTED A TORNADO WITNESSED BY STATE POLICE. SUMMARIZING: IT IS SAFE TO SAY THAT ALONG WITH HURRICANCE GLORIA, THERE WERE TORNADOS IN THE AREA. FORTUNATELY THEY DID NOT ADD SIGNIFICANTLY TO THE DAMAGE ALREADY DONE BY GLORIA. THERE WERE NO LIVES LOST: NO BUILDINGS BLOWN APART, ETC TO WARRANT NOT PERSONALLY INVESTIGATING THESE REPORTS. THEY WILL BE RECORDED AS HAVING OCCURED IN OUR LOCAL STORM REPORTS AND STATION CLIMATOLOGICAL HISTORY BUT MOST IMPORTANTLY WILL SERVE AS A REMINDER IN FUTURE HURRICANE EVENTS THAT TORNADOS CAN OCCUR WITH HURICANES. INCIDENTALLY) THE NATIONAL WEATHER SERVICE HAD A TORNADO WATCH IN EFFECT FOR SOUTHERN NEW ENGLAND FROM 10AM EDT TO 6PM EDT FRIDAY SEPT. 1985. RAMELLA So why did they not record these are tornadoes (they are not in NCEI Storm Data - even though it says they were recorded). Probably the same reason as Bob, magnitude of HU event/wind damage overshadowed individual spinner reports. Of course, this would not happen today. Once the NWS MAR occurred in the mid-late 90s, wx verification and outreach greatly expanded, and so did what got logged in Storm Data. As added bonus, here is the LSR from WSO BDR for the July 10, 1989 spinner event. WxWiz is . I recall this report vividly. What caught my eye the most was 4.4" of rain in 1/2 hr! I believe it b/c it was a MONSTA HP beast. The sky darkened black as night for this storm.

Bob tracking farther E made all the difference, If you were in SE MA and CC, it was the BIG BLOW. You can't expect too much when an accelerating HU passes E of you location at this latitude if you are looking for wind. R++ OTOH? However sometimes wild turkey surprise occurs. Edna in Sep 1954 BOS G88KT, it highest gust on record (beat G87KT from Carol 10 days earlier), and it was out of the NW as Edna passed over CC. Edna was going ET rather quickly and I'd bet good $$ it was a sting jet over SNE. If you look at HU Fiona's epic transition S of NS in Sep 2022, that's what likely happened to Edna. Bob's landfall at BID was 90 kt, which is considerably above Gloria's (75 kt) and Belle's (65 kt) landfalls -- the strongest since Donna in 1960, so don't dis Bob! NWS BOX told me not long after Bob, they had a number of reports of "Scott spinners" on CC, but due to the extent of the straight-line wind damage and resources, they could not investigate those reports. This was 2 years before the WSR-88D was installed, which now makes it much easier to pin down spinner reports and check specific areas, never mind cameras everywhere. So the next HU that makes landfall in SNE, we'll likely see a number of spinners.
