The highest daily maximum temperature of the First Order Stations for March was 60°F reported at Annette on the 31st of the month. Annette also held the spot for the highest mean temperature for the month at 42.5°F. The lowest temperature was ‑28°F at Barrow on the 17th, and Barrow also reported the lowest March mean temperature at ‑7.2°F.

Daily mean temperature deviation from the normal temperature for the mean of the first order stations for March 2015.
There were quite a number of daily temperature record events once again in March, and like December, January and February, all were high events; either new records or tied events. The winter of 2015-16 is only the second one on record for Fairbanks where the temperatures did not drop below -30°F by the end of March. The only other winter on record where Fairbanks did not reach ‑30°F is 1976-1977. The daily high in Anchorage of 53°F on the 31st was a daily record, and also the highest temperature for any March day in Anchorage. Sitka set of tied its daily high eleven times in March, which is itself quite a feat. Yakutat had eight record high events, while Juneau and Haines each had six.
A very nice March in Southeast was reflected in a number of new high monthly average temperatures. March was the warmest on record for Juneau at 39.9°F, 0.3°F above the previous record from 1984, for Ketchikan at 43.8°F (43.5°F from 1915), Sitka with 45.1°F (42.5°F from 1984), and Haines at 39.6°F (39.1°F from 1915).
It was the second warmest March on record in Kodiak with 39.3°F after the record of 40.4°F set in 1983. Homer also had its second warmest March (36.8°F) after the 38.0°F observed in 1977. It was the fourth warmest March for Cordova and Bettles, while it was the fifth warmest for Anchorage.

Precipitation
March precipitation was higher than expected, with the overall precipitation calculated as 17% above normal; this calculation was based on the mean of the deviations in percentage of the First Order Stations. Nine of the First Order Stations and eleven 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. It was also the same as March 2015, which had a precipitation total of 17% above normal too. The greatest daily deviation of 334% occurred on the 28th. Nome had the greatest negative deviation from normal, with a total of 0.04", or just 6% of the expected amount of 0.65". The leading station with a greater than normal precipitation amount was King Salmon with 179% above normal. Talkeetna had 172% above normal, while Gulkana observed 147% above normal.

Newsworthy Events
March started out with the second wildfire of the year reported in Mat-Su on the 1st.
Zero visibility and winds up to 35 mph were reported on the Dalton Highway on the 3rd as a blizzard impacted the area. Avalanche reduction efforts were done along the Klondike highway also on the 3rd, while downtown Juneau experienced winds up to 40 mph. With Anchorage having nearly no snow on the ground, the Iditarod Sled Dog Race planned a shortened ceremonial start in Anchorage, while Alaska Railroad was tapped to haul up to 350 cubic yards of snow from Fairbanks for the race start. Snow was finally reported in the Southcentral region on the 4th with the highest snowfall totals of 4" for Seldovia, and 3" for upper Potter Valley. The slush generated treacherous roads that caused more than 50 vehicle accidents in Anchorage on the 4th.
More blizzard conditions on the North Slope on the 7th impaired travel with winds up 40 mph and drifting snow for zero visibility. Travel was not advised along north portions of the Dalton highway, and work slowed on controlling the overflow along the Sag River. Hydaburg reported a wind gust of 61 mph on the 8th. The Eaglecrest ski area canceled its annual its Slush Cup event scheduled for the 10th, and planned to close on the 13th, however it ended up staying open one extra weekend. Avalanche reduction efforts were used on the Dalton Highway on the 13th between mileposts 235 and 250. A winter weather advisory was issued for areas of the Mat-Su for the 16th. Snowfalls totaled up 5" for the areas of Trapper Creek and Moose Creek, while Palmer observer 4". Fairbanks received a 1.8" of snow in the 15th, first snowfall over 1" since November 26th, 2015.
More snowfall on the 19th in Anchorage brought more vehicle accidents, with more than 50 reported. The Eagle River area received totals up to 11" and 6.4" was reported at the Anchorage International Airport. More snowfall in Southcentral area on the 28th resulted in totals of over 4" in Valdez and bringing the snowpack to 30". Avalanche control was performed along the Richardson Highway in Thompson Pass as well as the Parks Highway between mileposts 194 to 321 on the 29th. Mild weather in Southeast allowed the early opening of Montana Creek Road in Juneau on the 30th. The road is normally opened on May 1st. The Salcha wood cutting ice road was closed on the 31st due to deteriorating conditions due to the warmer than normal weather. Klawock, in Southeast reported a high of 71°F on the 31st. This is, preliminarily, the highest temperature ever recorded in Alaska in March, beating the 69°F from Ketchikan set on March 28th, 1915.
