Alaska Statewide Climate Summary

June 2016

 

Temperature

 

June 2016 marks the ninth month in a row with temperatures above normal. The monthly mean temperature of all First Order Stations was 54.1°F, 2.4°F above the normal of 51.7°F. This is 0.5°F below the June 2015 mean of 54.6°F. Monthly mean temperatures (see table) were above normal for 17 of the 19 First Order Stations. Calculating the mean daily temperatures of the First Order Stations, 26 days of the month were above the 30-year normal (see Figure). The peak positive deviation for the month occurred on the 16th at 6.4°F, while the greatest negative deviation was _1.0°F on the 20th. On a monthly basis, Bettles held the greatest negative deviation from normal with a value of -2.0°F below its long-term mean of 58.5°F. Fairbanks was the only other station with a negative temperature deviation of just _0.4°F. Like May, Kotzebue had the greatest positive deviation of 5.5°F. Stations following Kotzebue with deviations exceeding 4.0°F were St. Paul (4.6°F), King Salmon (4.3°F) and Kodiak (4.1°F). Note that the four stations with the highest deviations are located in Alaska's coastal areas.

Daily mean temperature deviation from the normal temperature for the mean of the First Order Stations for June 2016.

 

There were a limited number of daily temperature record events as would be expected given the more moderate temperatures experienced in June. Unlike the last five months, not all were high events, with one new record low set in Bettles. St. Paul reported five daily high records in June.

Kenai tied June of 1983 for the warmest on record at 55.2°F. It was the second warmest June on record for St. Paul with 47.0°F, 1.5°F below the 2005 record. It was the third warmest June for Anchorage, Homer and King Salmon. This June was the fourth warmest for Sitka, Yakutat, Kodiak, and fifth warmest for Cold Bay.

 

 

Precipitation

 

June's precipitation was higher than expected, with the overall precipitation calculated as 13% above normal; this calculation was based on the mean of the deviations in percentage of the First Order Stations. Eleven of the First Order Stations and twelve days of the month reported above normal values. There were no days during the month without any measureable precipitation at all of the 19 First Order Stations. This is much wetter than as June 2015, which reported a deficit of 21%. The greatest daily deviation of 264% occurred on the 6th. The leading station with a greater than normal precipitation amount was Fairbanks with 140% above normal. Barrow reported 119% above normal. Nome was the relatively driest station at just 35% of normal precipitation observed. This is the fourth wettest June on record for Fairbanks.

Newsworthy Events

 

The Koyukuk River Fire was reported on the 3rd and crews were sent to fight the fire. It had grown to over 3,000 acres by the 6th and crews shifted to protect structures on the 6th after rain slowed the fire. The fire did grow to over 20,000 acres by the end of the month, but was placed in watch mode by the Fire Service.

 

Heavy rains, with snowfall at higher elevations, were reported across much of mainland Alaska on June 5th and 6th. Anchorage totaled 1.03Ó on the 6th. the third highest daily precipitation value on record. The wettest Anchorage June day is 1.62Ó from 1962. The heavy rain resulted in localized flooding of area creeks with water reported over Turnagain Boulevard. Heavy rain was also prevalent in areas of the Alaska Range with over an inch of precipitation reported at Eielson Visitors Center in Denali Park, which included serval inches of snow. A total of 1.19Ó at Caribou Peak north of Fairbanks, and 1.01Ó near Chena Hot Springs of rain were measured, and the rains caused area creeks and rivers to rise, but no flooding was reported.

 

On the 13th the last crews fighting the Medfra Fire in southwest Alaska (that had peeked in size at over 9,000 acres) were pulled off the fire. The Medfra Fire had started in May, and was a holdover from the Soda Creek Fire from the previous summer.

 

On the 18th smoke from the Big Mud Fire near Tanana drifted into the Fairbanks and other Interior areas. The Big Mud Fire started on June 1st and had reached about 20,000 acres by mid month, then 40,000 acres by the end of the month. The Tetlin River Fire started on the 17th and grew to 700 acres by the next day from high winds. Residents of Tetlin were asked to be prepared to leave, but no evacuations were ordered and about 175 fire fighters were on scene. The number of fighters increased to 120 by the 20th as the fire jumped the Tetlin River and burned right up to the village airstrip. The fire was 75% contained at about 800 acres by the end of the month.

 

On the first official day of summer, June 21st, snowfall was reported in Atigun Pass in the Brooks Range.

 

The 25th and 26th saw a large number of thunderstorms across Alaska that resulted in more than 20,000 lightning strikes. Much of the lightning was concentrated in the Interior portion of the State, which started more than 60 wildfires. Most were started in limited suppression areas, and many were put out with the heavy rains that followed, especially the fires north of Fairbanks in the Chatanika area. Five of the fires had crews dispatched to fight them. A quarter inch of hail was reported north of Fairbanks, while Ambler Lake received 2.00" of rain on the 25th. The Denali area reported 0.82" on the 26th.

By the end of June wetter weather had retuned to much of Interior Alaska. There were about 80 active wildfires, and approximately 120,000 acres had burned from more than 350 wildfires for the season.
