November 2014 Statewide Summary

Alaska Statewide Climate Summary

November 2014

 

Temperature

 

November 2014 temperatures were decidedly above normal across the state, with all 19 of the First Order Stations reporting positive deviations. Calculating the mean daily temperatures of the First Order Stations (see Figure), 26 days of the month were above the 30-year normal. The only days with below normal temperatures were the 3rd to the 6th. The peak deviation, an extreme 16.4°F, occurred on the 12th. The monthly mean temperature of all First Order Stations was 26.2°F, a significant 7.0°F above the normal of 19.2°F. This is 5.0°F above the November of 2013 mean of 21.2°F. King Salmon held the greatest positive deviation from normal for November at a highly substantial 13.6°F above its long-term mean of 22.9°F. Stations following King Salmon with positive deviations equal to or exceeding 10°F were: McGrath (10.6°F), Homer (10.2°F), and Kotzebue (10.2°F).

 

The warmest temperature for the First Order Stations was 54°F reported at Annette on the 5th, and Homer on the 12th. Annette also reported the highest mean temperature for the month at 40.3°F. The coldest temperature was -26°F at Bettles on the 27th. Gulkana reported the lowest November mean temperature at 6.0°F.

Daily mean temperature deviation from the normal temperature for the mean of the first order stations for November 2014.

 

A fair number of record temperature events were reported for November, and unsurprisingly, all were new record highs, with no new lows noted. All were set from the 11th to the 20th, during the exceptional warm spell. King Salmon had a total of nine new records set, with eight of those consecutive from the 11th to the 18th. Nome had five events both new and tied, with four in a row. The high of 56°F in Cordova on the 18th is the warmest temperature recorded in Cordova in November since the high of 59°F from November 11th, 1912. Bethel's average minimum temperature of 22.5°F broke the 21.7°F record set in 1970.

Precipitation

 

November was a dryer than normal, with the overall precipitation calculated as 18% below normal; this calculation was based on the mean of the deviations in percentage of the First Order Stations. Fourteen of the First Order Stations and 22 days of the month reported below normal values. This is in contrast to the wet November in 2013 that had 51% more precipitation than normal. The greatest daily deviation of 102% occurred on the 29th. On a monthly basis, Barrow had the greatest positive deviation from normal, with a total of 0.49", or 133% above the expected amount of 0.21". No other station had a greater than 100% deviation. Leading the stations with lower than normal precipitation totals was Gulkana with just 13% of normal. Other stations with less than a third of their normal precipitation were: Delta Junction (22%), Bettles (25%), Fairbanks (27%), Talkeetna (29%) and Anchorage (30%). The lack of any precipitation in Juneau on the 11th ended a 40-day streak of at least some precipitation recorded, 14th longest in the station's history. Juneau's first measurable snowfall of the winter did not occur until the 29th. Both November 1943 and November 2002 were snow free in Juneau.

Daily mean precipitation deviation from the normal for the first order stations for November 2014.

 

 

The maximum monthly precipitation total reported for the First Order Stations was 13.00" at Kodiak, and Kodiak reported the highest daily total of 2.42" on the 11th, a new daily record. The highest one-day snowfall occurred at Juneau on the 30th with 8.5Ó, a new daily record. Nome reported the highest monthly snowfall of 12.7", and Nome also reported the highest snow depth at 10Ó.

 

Given the general lower than normal precipitation record in November, its not surprising there were a very limited number of precipitation record events during the month. The table below lists the six noted events.

Newsworthy Events

 

November started off with travel advisories issued for the North Slope portion of the Dalton highway for high winds and blowing snow on the 5th, hindering travel in that area.  Also on the 5th, warnings started coming out for the 9th, when the remnant of typhoon Nuri was expected to move into the Bering Sea and impact the western and central Aleutian Islands. The storm stretched over 2000 miles across as it moved into the Bering Sea, and the lowest pressure measured was 929.8 millibars. Shemya Island recorded sustained winds of 70 mph and guests up to 96 mph. The storm weakened as it moved east across the Bering Sea. No significant damage was reported along the storms path.

 

Also on the 9th, Fish and Game warned Southcentral residents not to put birdseed out yet, as the warm temperatures had kept some bears awake late into the year. Warm temperatures in the Interior on the 10th created icy roads across the region. Light freezing rain was forecast for areas of the Interior on the 18th. By Thanksgiving, there was no snow on the ground in Anchorage; the four inches that had fallen had melted. The city normally has about 17 inches of snow by that time of the year. A blizzard hit the Dalton Highway on the 20th, and travel advisories were issued for strong winds and drifting snow.

 

Fairbanks's first measureable snow of the month came on the 25th. The Moose Mountain ski area in Fairbanks opened on the 28th. Alyeska Resort near Anchorage delayed its usual Thanksgiving weekend opening due to the warm weather preventing the production of artificial snow. Storm warnings and watches were issued across large sections of the state on the 29th and 30th. The unusually warm November slowed the freeze up of the Kuskokwim River, preventing its use as a transportation corridor by Thanksgiving.
