All southern and western locations were warm relative to normal,
which is no surprise given the unusual warmth in the waters of the
Bering Sea and Gulf of Alaska. St Paul Island recorded by far its
warmest September on record (1949-present), and remarkably the month was warmer than the average August in that location - and
August is the warmest month of the year on average. August 2014 was also the warmest August on record on St Paul Island. Cold Bay also saw
its record-breaking warmth continue, with the warmest September on
record (1950-present).
September was much wetter than normal in Fairbanks, but only because of the deluge at the beginning of the month; surprisingly Big Delta, McGrath and Bettles were all drier than normal.

As far as I know, the lowest temperature observed in the state in September was 6 °F at the new Ivotuk CRN site, observed on both the 5th and 26th. The Chicken COOP reported 8 °F on the 25th, 26th, and 27th. One might think that it is unusual for no sub-zero temperatures to be reported anywhere in the state in September, but in fact the normal statewide minimum September temperature is above zero. The chart below shows the statewide temperature extremes in September between 1950 and 2013.
Finally, here's the Fairbanks September weather summary from the NWS.
