Short answer: the Great Vowel Shift.

Long answer: before the Great Vowel Shift began around 1400, there was a phoneme /x/ (written gh or ȝh) in Middle English. By Modern English, /x/ had either mutated to /f/ or had become silent in standard dialects.

Long vowels had generally shifted to become various diphthongs. Vowels are notoriously slippery characters in the continuing tale of the GVS.
