This isn't quite Alaska weather and climate, but isn't far off and seems notable enough to write about. The Canadian town of Inuvik, close to the Mackenzie River and not far from the Arctic Ocean, recorded their warmest week on record for the week ending Friday, August 9. Below are the top 6 warmest weeks (non-overlapping; see a note at the bottom about the station locations):
August 3-9, 2013 71.9 °F
June 30-July 6, 1998 71.4 °F
July 10-16, 1989 70.6 °F
July 17-23, 2001 70.6 °F
July 28-August 3, 1994 70.5 °F
June 26-July 2, 1982 69.7 °F
As we've seen for Alaska locations this summer (notably Fairbanks), it was the high overnight minimum temperatures that really set this event apart from others in the past. The highest week-average minimum temperature broke the previous record by a large margin:
August 4-10, 2013 62.0 °F
June 30-July 6, 1998 59.9 °F
July 10-16, 1989 59.3 °F
July 30-August 5, 1994 59.3 °F
July 17-23, 2001 59.3 °F
July 2-8, 2012 59.1 °F
The weekly maximum temperature was the third highest on record.
Besides the event itself, it's interesting how late in the year it occurred, with average temperatures about 3 °F lower than at the climatological peak around July 10.
The chart below shows the minimum temperature observations since May 1; most of the summer was not outstandingly warm until August arrived.
**Note: I've combined data from Inuvik Airport (1957-2006) and the Inuvik climate/upper air site (2004-present). The two sites are just a couple of km apart, with the climate site being 35 m higher. I verified that during the brief 2004-2006 period of overlap, the June-August daily minimum temperatures had almost no systematic difference (climate site less than 0.1 °F warmer), whereas the maximum temperatures were warmer by 1.5 °F on average at the airport. This makes the record all the more significant, given that observations are now taken at the climate site.
