Why tonight?

If we use UTC and the time of your post as our reference, then presumptively you are talking about the thing happening within the next 4-16 hours, give our take 4 hours.

But why?

Are we experiencing ongoing "supply shock?"

or is something else going on?

I am not saying that I disagree with your feeling, whether it is a gut feeling or a SOMA^{tm - d_eddie} feeling, but we surely are within the top of the "don't wake me up" zone, so I am not going to presume getting through the top of it, even though there still is some room for movement within the top of the zone, yet at the same time, there is no reason that we might not continue to bounce around in these here parts.. except surely the ONGOING  net vacuuming up of BTC by the various BTC spot ETFs on a daily basis surely cannot be healthy for anyone expecting down and or sideways BTC price performance in the coming weeks and/or months,

and at the same time, I am coming to a similar kind of assessment that it is almost like the BTC price has to double or triple from here in a fairly short period of time to merely help with the ability of spot BTC ETFs to be able to continue to absorb actual BTC rather than fake ones.. but even conceding all of that still would not necessarily meant that more UPpity is imminent, including breaking out of the "don't wake me up zone" and getting into "no man's land" while passing through "hot butter" territories.

Pray tell, what I might be missing in terms of your current vision?..including that as of about a month ago, we had a two-year high of $49,048, but then a correction down to $38,505... but then perhaps a somewhat overly rapid shooting up from near the bottom and mid of the "don't wake me up" zone and getting into the top of the "don't wake me up" zone.. but still we don't get any kind of automatic continuance UPpity.. because if we actually get into "no man's land" while passing through "hot butter" territories then surely we could end up losing momentum if we end up getting there too quickly, no?  or do you consider that BTC buy pressures (support) will be able to keep up so that we would clearly be able to get through "no man's land" - aka "bat country" and therefore if successfully making it through such, then we may well end up ranging in the $82k to $100k arena (which price range still has not been named - because it is likely too early to be too presumptuous about even getting to that $82k to $100k price area in a relatively short period of time, if that might be in the short-term cards...)?
