"In fact, tornadoes are one of the more unpredictable forms of severe weather..." - this signals that the first blank must denote something which is a contrast to unpredictability. So, harbinger (C) is correct.
"although radar can detect signs..." - this signals that radar alone cannot detect tornadoes and so it requires eye witness confirmation. So its corroboration (F).
Hence, (C,F) is the correct answer.
"although radar can detect signs..." - this signals that radar alone cannot detect tornadoes and so it requires eye witness confirmation. So its corroboration (F).
Hence, (C,F) is the correct answer.

The statement that tornadoes are unpredictable is presented as counterevidence to an assertion made in the first sentence. This should clue you in to the kind of word you need for the first blank - specifically, a word implying that green skies predict tornadoes. Propagation means multiplication or dissemination and does not really make sense in this context - eliminate it. An incursion is an invasion or a harmful inroad, which still does not quite capture the notion that green skies precede tornadoes. The correct answer is harbinger (an omen).
As for the second blank, we are told that even radar is not an entirely reliable indicator of tornadoes, and that eyewitness accounts are also needed; the missing word must mean something like confirmation. Reciprocity means mutual exchange; it is somewhat awkward here, particularly given that we are not told that the eyewitness accounts require radar confirmation. Approbation means or commendation or official approval, and is again a bit out of place here; it implies an approving attitude rather than simple confirmation. The correct answer is corroboration, which means confirmation or authentication.
