It sure looks like mine do when fusarium starts getting to the plant. I wouldn't think you would have it that far north but with tomatoes all the rules go out the window.
I have been living with that mess for all four decades of my gardening but had some relief the past few years because of grafting with triple fusarium resistant root stock but this year I have had a resurgence. I think it is just a bad batch of root stock seed.
Maybe a cold winter will knock it back out of your garden so you won't have to worry about it next season.
