Yeah, a lot of snow. I logged into the database and checked data from March 2006.
Nelaug has an official weather station (142 m asl). I also checked Stavanger, Oslo and Trondheim (Airport/Værnes), and a few other places.

March 2006
Mean snow depth / max snow depth
Stavanger (Sola, 7 m): 3 cm / 8 cm
Nelaug (142m): 89 cm / 145 cm (!)
Oslo (94 m): 48 cm / 60 cm (Oslo city forest at 360 m asl had up to 124 cm!)
Trondheim (12 m): 25 cm / 35 cm (near Røros up to 107 cm max depth)

Data provided by met.no.

Very stark difference from the west coast (Stavanger) to Nelaug.

The south coast can see more extreme snowfall than Trondheim and Olso.

As you travel east of the southernmost point in Norway (Lindesnes), the Atlantic influence decreases. Nelaug (near Arendal) is E of Lindesnes.
At the same time, the topography of the south coast makes it more vulnerable to large snowfall than either Oslo or Trondheim, if just a winter low is in the right position to give persistent S/SW flow cold enough for snow.

Nelaug is on average almost the same as Trondheim wrt temperatures in mid-winter, only very slightly colder than here. Torungen, at the coast 30 km from Nelaug, is 4C warmer in winter.

Nelaug had a record low of -23.7C, Stavanger -13.3C, Oslo -15C.

Funnily, it was also the sunniest March ever.
Cold, gloomy and rainy in my corner of France then, snow in the north of the country. We had a northern German March, and you got the siberian one.

I expect maximum temps to stay the same or increase VERY slightly, and minimum temps to increase by 0.2 to 0.6 degrees, depending on the month.

I'm predicting for the Midwestern U.S.

I should note that the US uses 29 day smoothed averages, so the December 1991-2020 Averages won't be complete until after 1/14/2021

I think they should go to using a 50 or 60 year average. A lot less prone to being influenced by freak events.

The problem is that average low temps would be too low, because you would have several years before UHI in those numbers
