Vowels:
Pseudo-Northern Cities shift:
/æ/->[ɛə]->[eə]->[ɪə]
/ɑ/->[a]
/ɔ/->[ɔə]->[ʊə] (this differs from the standard Northern Cities shift. and happens under the influence of New York English)
/ʌ/->[ɔ]->[ɑ] (Due to  /ɔ/ going in the opposite direction from the normal shift, there's enough "room" for /ʌ/ to migrate to fill the void left by /ɑ/)
/ɪ/->[ ̞ɪ]
/ɛ/->[ ̞ɛ]
Changes to diphthongs:
/aɪ/->[əɪ]/_C[-voice] (Canadian raising)->[ɑɪ] elsewhere
/aʊ/-> [æʊ]
/eɪ/->[eː]
/oʊ/->[əʊ] (under the influence of California English)
