June 2013 Statewide Summary

 

Temperature

Temperatures started off the month mixed for the first week, then stayed above normal, often significantly above normal, for the rest of the month. The mean temperature of all first order stations for June was 55.2°F, 3.3°F above the long-term mean of 51.8°F. Nineteen of the 20 First Order Stations reported positive deviations, with Interior stations reporting the most extreme deviations from their expected temperatures. Fairbanks topped the list with a significant positive deviation of 6.4°F. Following Fairbanks were Delta Junction (5.6°F), Kotzebue (5.1°F), and Gulkana (5.0°F). Saint Paul, with -1.2°F, was the only station with a negative deviation. Anchorage had seventeen days with a maximum temperature at or above 70°F, breaking the record of thirteen days from June of 1936. June was the fourth warmest on record for Anchorage. Fairbanks had the third warmest June on record, with sixteen days where the temperature hit 80°F or warmer, breaking the previous record of fifteen days from 1957. Juneau had the second warmest June since 1943. King Salmon also had the second warmest June on record. Details for each station can be reviewed in the table below.

Description: First Order Temperature

Daily mean temperature deviation from the normal temperature for the mean of the 20 first order stations for June 2013.

 

June brought numerous new record temperature events that reflected the overall trend for the month, with no new record lows reported. McGrath was again on a tear in June, continuing the trend of four new record highs in May with five more in June. The record high of 94°F on the 17th was also a new all time high for McGrath, topping the old record of 90°F set on June 15th, 1969. McGrath also set seven new high minimum records in June (not shown). Valdez topped McGrath with a total of seven new record daily high temperatures, and six new high minimum records (also not shown). In addition, the record high of 90°F on the 17th was a new all time high for Valdez, breaking the old record of 87°F from June 25th 1953. The 17th also saw a number of other all time high records set: Talkeetna hit 96°F, topping the 91°F record set on June 14th 1969 and June 26th 1953. Cordova reached 90°F, breaking the 89°F record from June 16th 1995. Nome tied its all time high from July 31st 1977 on the 19th with a high of 86°F. That same 86°F is a new June high for Nome. The minimum temperature at Fairbanks of 70°F on the 25th was the warmest minimum daily temperature on record.

Precipitation

Unsurprisingly, June precipitation was lighter than normal with fifteen of the 20 stations reporting below average totals. The mean value of all 20 stations was calculated to 14% below normal. Gulkana reported the greatest negative deviation with just 19% of the expected value. Rounding out the stations with less than half of normal totals were: Bettles (30%), Fairbanks (31°%), Talkeetna (35%) and Anchorage (47%). Topping the stations with heavier than normal precipitation was Nome with 158% above normal. Next came: Barrow (141%) and Kotzebue (57%). Only two stations experienced snowfall in June: Barrow with 0.3", only 43% of normal, and Nome with 0.1", 33% of normal. Precipitation details are presented in the following table.

 Description: First Order Precipitation

Daily mean precipitation deviation from the normal for the 20 first order stations for June 2013.

 

The low number of precipitation records in June correlated with the generally sunny weather. Juneau started the month with 0.85" of rain on the 5th, topping the 1993 record of 0.78". On the 15th Nome received 0.68", just breaking the 1994 record of 0.60". Cold Bay's total of 0.73" on the 21st broke the old record of 0.46" that had been in place since 1951. Valdez's new precipitation record of 1.16" on the 28th, more than doubled the 1991 record of 0.56". Finally, on the 30th, King Salmon received a total of 0.75", also more than doubled the old record of 0.35" from 1982.

This satellite image from NASA's Terra satellite shows rare, nearly cloud-free view of large portions of the state on Wednesday, June 17th, 2013. This image demonstrates the extent of the high-pressure system that dominated the weather in June, and drove a number of high temperature records on the 17th.

 

 

Newsworthy Events

The short transition from spring to summer was evident in Tok as the spring run off resulted in flooding of local roads and low lying areas at the start of the month. The water affected about a dozen homes before receding. At the same time, lightning started what was at that time the state's largest wildfire, named Bitter Creek, 60 miles from Tok. Fighting efforts continued until the 11th when most staff left, and total area burned was estimated at 2,200 acres and came within a mile and half of the Alaska Highway. Smaller fires also started in Delta Junction, and Healy. Seasonal run off affected the Richardson Highway all the way to the middle of the month. Rabbit Creak in Anchorage saw a surge of water on the 14th from a suspected ice dam break. After substantial rain fell in the Salcha river basin on the 4th and 5th, flood warnings were issued. The rain helped dampen Interior fires. The heat wave that hit the state about mid month created ideal conditions for wildfires, especially in the Interior. Fires started near Harding Lake and North Pole on the 17th. A large fire near Lime Village threatened the town and fire crews were working hard protecting structures, and it would eventually make it to within a half mile of the village. The Kaouti fire started near Two Rivers community on the Chena Hot Springs Road also started on the 17th, and was fought vigorously, so while no evacuations were issued, and no structures were lost, the road was temporarily closed from mile thirteen to sixteen. The fire topped out at 120 acres, and ended up being battled for two weeks. The Skinny Road fire at about mile 324 of the Parks Highway popped up on the 25th, resulting in the closing of the highway on the 26th, and frequent delays after that time. About 120 fires were burning across the state at the end of the month.

 

The Denali Highway was finally opened to through traffic on the 5th, several weeks later than normal. The longer than normal winter was blamed for a substantial die off of fish in Quartz Lake. In a reversal, warm water and lack of oxygen was blamed for the death of hundreds of fish at Ballaine Lake near Fairbanks at the end of the month. A mosquito boom across the Interior resulted in a shortage of repellent in Fairbanks, while the hot weather drained the stores of any type of fan or air conditioners. The dry conditions resulted in the City of North Pole banning firework sales, and local Interior officials pleaded with the public to refrain from their use. Woodcutting was curtailed across the Interior as well. The dry conditions had the City of Anchorage pulling a fire truck out of retirement as well as instituting a burn ban. Thunderstorms were noted at Barrow in 13th.

 

This information consists of preliminary climatological data compiled by the Alaska Climate Research Center, Geophysical Institute, University of Alaska Fairbanks. This summary is based on the 20 first order stations in Alaska operated by the National Weather Service. Extreme events of other stations are also mentioned. It should be noted that the new climate normals for the time period of 1981-2010 are applied for the calculations of the deviations, and they can be slightly different from the old normals (1971-2000), which were in use up until end of July 2011.
