Sunday morning was the first day of the season for it to drop below zero at the cabin.
Thursday morning we saw our first -20F.

20F Degrees
Well, Fairbanks did not get through September without a hard frost. The thermometer read a very solid 20F in the Goldstream Valley.
Late afternoon I visited the bus to drain the water tank, and the frost was still on the ground.
Winter is around the corner.
A bit of a chilly start
The revamped Yukon Quest race had its start on Saturday morning. It was a balmy -45F at the first mush.
Officially, Fairbanks dropped to -50F that morning. It was our first “official” -50 since 2017. It was the third morning at the cabin during this cold snap, that I saw -50 on my thermometer. For some reason, my cabin is not considered the official weather station for Fairbanks. For purely political reasons, that honor lies with the Fairbanks International Airport.
Speaking of streaks broken: I broke my previous record for distance traveled with “thumpity-thumpity-thumpity” coming from my tires. For those left out in the heat, tires make that sound after a flat spot forms where they met the driveway during extreme cold temps. It usually only takes a few hundred yards for the tires to warm up enough to reform, but in fifty below, the flat spot lingers for a mile or so.
Chilly Monday
A cold front has moved into Interior Alaska, bringing a full day of rain on Sunday and cool temps on Monday. The soggy Sunday even drove me to light a fire in the wood stove. At 41F degrees, Fairbanks won’t even hit half of where San Antonio will be.
I’m not complaining, but I’m also not ready for that four letter word that starts with an ‘s’.
Launching balloons
I’ve been out at Poker Flats, which is outside Fairbanks, on several occasions when they were launching weather balloons. These days, most weather balloons are filled and launched by robotic launchers called autosondes, which takes some of the romance out of weather balloons, but that’s not the purpose of this post.
In the United States alone, there are 92 sites that launch two balloons every day of the year. There are over 800 locations worldwide doing the exact same thing. Here in Alaska, we have 13 sites that launch weather balloons twice a day, every day, and always at the same time: Midnight and noon Greenwich Mean Time.
A small collection of weather instruments, called a radiosonde is attached to the balloon which collects data and transmits that data back to the NWS as it rises. A weather balloon makes it to roughly 100,000 feet before it pops and falls back to earth. These days, radio balloons are highly biodegradable.
The first weather balloon with a radiosonde launched from Fairbanks in 1933. They started launching two balloons a day in 1941. I’ll let you do the math, but no matter how you figure it, that’s a lot of balloons.
We call this mild:
The forecast calls for another week of mild temperatures across Alaska’s Interior.
Chilly Chicken
A deep freeze swept over much of Interior Alaska this week. Not only was Chicken the cold spot in the state with a low of -57F, their high ended up being only -50F. They hold the spot as the first location in Alaska to officially see a high of minus fifty or colder this season.
By comparison, the thermometer outside the cabin read a balmy -33F Monday morning.
