After the 14+ inches of snow dumped on us last week, there is only one year since recording began, that snow depth this late in the season was deeper. That was the infamous Winter of 1990-91. We have a whole lot of snow on the ground… and on the rooftops.
We have also set some cold records so far in April. On more than one morning, we have tied the record low temp in Fairbanks. On Friday, we tied the record low of -16F, and shattered the record low high when we climbed to a paltry +3F.
Saturday night saw a return visit to the deep freeze, with the temps dropping to -29F officially at the airport. It dropped to -35 at the cabin. The record low for the month of April is -32F, which we have left intact. Not to be outdone: Old Crow, YT dropped to -40.2C. Way to go Yukon!
Temperatures for this coming week have us seeing +40F for the first time since October. That is also a new record.
Anchorage made a go at it, I have to admit. They had been putting together an impressive run of days at, or below, freezing. Not Fairbanks, impressive, but impressive none the less. The record for Anchorage was, and still is, 59 days below 32F. The run ended at 58 days. Oh, so close!
The area north of the Brooks Range has the best grip on below freezing streaks, hitting 250 days of 32F or below.
The Aleutian Chain was rocked by an incredible storm over New Years. The wonderfully named Bomb Cyclone, set a record in Alaska for a low pressure system.
High and low-pressure systems form when air mass and temperature differences between the surface of the Earth, and the upper atmosphere, create vertical currents. In a low pressure system, the air currents flow upward, sucking air away from the earth’s surface like a giant Shop*Vac.
Eareckson Air Force Base on Shemya Island recorded the record low pressure at 924.8 millibars.
A sea buoy off of Amchitka Island, registered a wave at 58.1 feet. Winds at Shemya hit gusts of 83 mph. This was an impressive storm that pummeled the outer islands of the Aleutian Chain. From Atka to Adak, the islands were seeing 40-50 foot waves and hurricane force winds.
St Lawrence Island and the Yukon Delta saw high winds and blizzard conditions when the storm hit Alaska’s mainland.
Unlike a hurricane, which extract heat from the ocean, as they grow in power, a maritime cyclone creates energy by drawing together warm and cold air masses. It’s the energy created when the warm air rises and the cold air sinks, that gives rise to the cyclone.
It’s been an odd year, all the way around, but especially with the weather. Fairbanks had a dusting of snow last week, but nothing measurable. Anchorage had measurable snow before we did.
Juneau beat both Fairbanks and Anchorage for the season’s first freeze. Juneau! That’s just not right.
So winter is coming for Fairbanks. Even though 2-3 inches of snow is hardly much to get excited over, at least it’s a start. Denali Park & Black Rapids are at least looking to get a good jump on the season.
I guess I’m ready for snow. Let it fall.

The temperature finally climbed above zero, reaching 9F on Monday. That breaks a streak of 34 days where the temp never went above 5 degrees. It’s the fourth longest streak of its nature, since recording began.
The longest such streak is 49 days, which happened in 1942-43.
Although this season’s streak was long, it wasn’t excessively cold. In 1975, a similar streak had several days reach -60F. The 2020 streak saw four days where the temperature dropped to -40.
Regardless, I was thrilled to be outside on Monday in single digit temps.

A large storm is barreling into Western Alaska this week. Heavy rain and strong wind is expected. Gusts of 65-80 mph are possible.
Currently, the vast majority of Western Alaska is devoid of snow. The entire western coast has no sea ice. The ice would normally offer some protection from coastal erosion. The high winds will certainly set back any sea ice growth.
Gale force winds are expected to continue in the impacted areas through Wednesday.
Bird’s eye view: First day of ice on The Pond. The beaver’s trail can be seen to the left.
For this season, we had the first 24 hour period over the weekend where the temperature did not get above freezing. It came 11 days later than on average.
The Pond received its first full coat of ice by Sunday morning. Thin as it is, one could see where the beaver swam under the ice.
The fire in the wood stove is still not going full time, however. One every other night has been enough to keep the chill out of the cabin. Anything more would drive me out of the building from the heat. As it is, an evening fire requires at least one open window at these temps.
