Quick final (?) weather update

Happy Korteloppet morning, everybody, and check out our podcast from yesterday.

A quick note on weather: all signs are still good.

Friday morning is cold, but it should be in the 20s by Korteloppet time and crest just above freezing—maybe as warm as 35—by 2 or 3 p.m. It will be breezy, as southwest winds peak later in the afternoon.

Tonight it is clear, calm and colder, down to around 15, and plenty of time below freezing to freeze the trail solid, from the top down and, since the snowpack will retain a lot of cold, from the bottom up. I would assume the Birkie will be grooming early to let the trail set up well overnight.

Then tomorrow, it starts out cool at race time, with the early waves going off around 20˚. But don’t overdress! The temperatures will warm during the race, up to freezing by about 11:00 and then continuing to warm into the 30s and maybe up to around 40. In the shade, the cold snow and shade should keep the snow frozen and fast, but in the sun, especially for later waves, on south-facing downhills and on the lake, it might get a bit slower and slushier. Good news on winds, though, which will remain light throughout the day, although any winds that do blow will be from the south or southwest.

As for the snow, the course may be slower than expected with the new snow, but I would assume it has been well-tilled and worked and should be solid. For the Birkie, I’d expect the section after OO to be quite transformed during the race today and to till up tonight with some colder powder below and ski quite fast.

(It should be noted that one model, the high-resolution NAM, keeps some low cloud cover in place on Saturday, with cooler temperatures because of this, but it is currently an outlier.)
