It's really just a matter of context (i.e. - the intended meaning).
If the weather condition being spoken is in the future, but the forecast says it will be inclement when it does arrive (so you're cancelling the village fete, or whatever), then of course it's expected.
But if the predicted weather has already started, it's perfectly grammatical to say it's expectedly inclement, if in fact that's what it is (in line with prior expectations). OED defines...
expectedly adv. in the manner expected, according to expectation;
Note that as J.R. says, expectedly is very rare compared to unexpectedly. We usually use as expected when that's the syntactic functionality we want (effectively, He appeared as expected is adverbial usage).
But if we reverse the expectations (and use simpler meteorological terminology), I have no problem with...
1: Due to unexpected bad weather the fete has been cancelled
2: Due to unexpectedly bad weather the fete has been cancelled
It should be fairly obvious that in #1 we weren't expecting bad weather at all (maybe the forecast said it would be sunny). Whereas in #2 we knew the weather would be bad (but we probably hadn't expected it to be so bad we'd have to cancel the fete). Unexpectedly, it was even worse than we had anticipated.
I must admit I don't know why we prefer as expected over expectedly in nearly all cases. It may be connected to the fact that we have many alternatives (naturally, obviously, predictably, typically, clearly, foreseeably, logically, etc. plus phrases like it goes without saying).
Such words are often used in sensitive/loaded contexts, so it's likely people learn to be extra careful with them. Perhaps expectedly is avoided because it raises the question of expected by whom? in too many contexts where we'd rather be more circumspect. So we tend to opt for more "impersonal" alternatives.
Statistically, and cross-linguistically, at university is more commonly-used than in university. Here's some numbers:
- British corpus:
- at university/universities: 504
- in university/universities: 243
- American corpus:
- at university/universities: 1,166
- in university/universities: 730
- Web corpus:
- at university/universities: 12,132
- in university/universities: 5,603
I wouldn't call any of these an overwhelming majority, so what's the difference?
Here's a clear case where you can't use at:
So, for the meaning of in that corresponds roughly to in the course of, you can't use at.

According to this Wiktionary page,
So, "a major cyber attack.." is a complement that the adjective due takes in your sentence.
The meaning, again according to Wiktionary's entry on due, is "owed or owing". Wiktionary provides the following example:
The note "not before a noun" means that due in this sense cannot be used as an attributive adjective, but only as a predicative or postpositive adjective. An attributive adjective is used like this:
In your example sentence, due is used predicatively. It would be hard to use it attributively in this sense anyway, since we need to attach the complement to it somehow:
(I used due before the noun world, that is, attributively, and inserted the complement between the adjective and the noun. The result looks outlandish).
