This appears to be a fairly low effort simulation of a WeatherStar 4000, but it's been done much better by someone else here: https://weatherstar.netbymatt.com/
Also for those of us like me who grew up with a cable provider that still ran the old WeatherStar III, there's this one: https://weatherstar3000.netbymatt.com/
The blurring/low quality effect in the weather.com version is so much convincing, it feels like watching it through a CRT tv
As others have stated, no, this isn't a simulation of WeatherStar. It does, however, look exactly like the weather channel did when I was a kid. (New Jersey and Maryland, in the 80s and 90s)
This is pretty neat. I think I probably get this transmission on Infochammel.
that one doesn't put my laptop to aspirate and it;s fast
Ughhhh snow storm tomorrow
This may be an age or geography thing, but Weather.com/Retro looks a lot more like the weather channels I remember than either of your two links.
I don't think they were trying to recreate the thing you were expecting, but it seems a little harsh to call it low effort. It's neat! A fun little nod to their history.
