UFO paint scheme, interesting history of the model itself...?

Anyway, remember how the bottom structure was damaged at LSPR? A piece of ice ripped part of the coroplast off under there yesterday so the tail is coming off.

You'll have a bare assed anal probe. Might be a market for the tail on this site, if advertised as one size fits all, some adjustment required.

It would need a lot of adjustment

"Snow Emergency" aka snow storm, on the 9th. I had to shovel it out and move it Sunday night, at which point the snow was up to the front turn signals.

We ended up with about 15"/38cm

Wow! We don't even have snow up here in southern Ontario. We've had snow fall a few times but nothing has stuck around.

That second photo is beautiful by the way.

Oh, have I got something for you guys! After a light snow today the car had a uniform inch or so of snow over it. I took it up to 100mph and look what happened!!!

I am in no way an expert but would like to try to decipher this stuff. Here's what I posit. It's not fact; it's hypothesis.

There are four longitudinal vortexes forming on the car that we can see now. The major ones are coming off the side windows and rotating up and in. As they turn, they sweep outward on the rear window, clearing the snow off. The lines of snow at the edge of the rear window show us the point at which the vortexes contact the air coming off the side window.

The smaller vortexes, which I'm not so sure about, are coming off the small belt line/shoulder of the car. You can see thin streaks of snow above the serial numbers on the rear quarter panels. I believe a similar thing is happening compared to the rear window, but the air is moving from the high pressure side of the car to the lower pressure top, creating a small vortex between those snow streaks and the side windows.

The triangles at the beginning of the boat tail display the turbulence aft of my "stealth" gap filler. There is an especially large turbulent area behind the hand hole on the drivers side that I use to pull the lift gate up.

There seem to be transverse vortexes rotating behind the pop-up headlights and you can see a high pressure zone at the base of the windshield (bottom right image).

The thing I'm confused about is the diagonal snow streak between the edge of the rear window and the middle snow pile. This seems to be in the middle of that major vortex. Strange.

Hopefully those conclusions are close to reality. I've messaged our resident expert aerohead to see if he'll have anything to say... what do you all think?

I hope you had a plowed road for that run.

What I see is snow on the front half of the tail and none on the back half. If the tail had followed the contour of the fender flank instead of the backlight, it would be all clear. (And maybe, with a little more taper, twice as long as it needs to be?)

Un-attached flow in the middle of the backlight?

The diagonal streaks are interesting. I'm starting to picture the vortex as like a sheet of paper with one end rolled into a cone, more than the spirals I supposed before.
