Beautiful day. Didn’t even have to use my AK.

yeah.   not here. I'm wonderin if there was a spray thing I don't know about.  But I was over in Sterling at Meadow Brook, basically a 1000 acres of orchards, open fields, with woody glades doing disc golf last weekend and there wasn't one.  Then I was over at Qual Ridge in Acton doing a regular golf there and again...none.   Why is massachusett special

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.

Were there a lot of thunderstorms around locally the day of the Worcester tornado? I thought I read somewhere Boston got a strong thunderstorm later that same afternoon.

What a week coming up. I think we see 90+ Tuesday to Sunday at BDL. 

Did Bradley even hit 90 during the past 3 days?

Ahead of the tornadoes, communities across the region were battered by massive hailstones, with baseball-sized hail reported in multiple towns. Cape Cod experienced vivid, continuous lightning for nearly three hours that evening

Oneonta is our target area for tomorrow!

Yeah but the humidity made it unbearable.

Thank you so much for this. I’ve often wondered what the day was like elsewhere

@weatherwiz go to Brooks BBQ, a few extra pounds on you will make spiders more fearful  !!

88-89F here. Not too bad with low humidity.

Just some added info.  Dr. Mel Goldstein (who passed away in 2012?) developed a Severe Weather Index in the 1970's that was used to gauge severe weather potential in SNE.  The index ranged from 1 to 5; 1 little or no severe wx potential, 5 was strong potential for tornadoes.  He worked closely with region electricity suppliers to gauge the threat for power outages.  In his morning update on October 3rd his index came in as 5!!!  He issued updates during the day indicating the tornado potential was high, and in fact called the Office of Emergency Management several times about his concern.  As a side note, I was living on the western edge of the Farmington Valley then, and observed obvious large scale low-level rotation racing northeast about 10 to 15 minutes prior to touchdown in Windsor Locks.

Sounds like '89. Had penny size hail and continous lightning for more than 3 hours in falmouth

The index was called DAX... Differential Advection Index.

Yeah, the trough that posed a cutoff  risk is being pushed a little to the east so that heat ridge moves in. Nothing impressive but upper 80s to lower 90s and spots possible later next week into the weekend. After that, it does look like a more humid set up moves in, still see that happening second half of June.

still haven't installed, these past few nights have been gloriously cool and perfect for sleeping.

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.
