A little snow possible late tonight into Friday; More snow possible Saturday night into Sunday followed by a brief shot of arctic air for early next week

Another clipper system will move across the area tonight and Friday bringing a little snow to parts of the Northland with accumulations of generally a dusting to an inch expected by Friday afternoon.

Mainly dry weather is expected Friday night through the day Saturday before more snow moves in Saturday evening and during the overnight. This snow is expected to linger through the day Sunday before tapering off Sunday night into Monday morning.

The usual differences in computer models continue to show up for this weekend’s system, including the storm track, where the main band of precipitation sets up, and just how much precipitation/snow will see in the Northland, but it’s looking likely that the entire area will get at least a few inches of snow between Saturday night and Sunday night, with a possibility for quite a bit of snow (6″+) especially near Lake Superior where lake enhanced snow is possible on Sunday along the North Shore (east wind) then shifting to the South Shore (north wind) Sunday night.

Looking at the ensemble data — 12z run from Thursday shows 54% of EPS members showing 6″ or more of snow in Duluth on Sunday, with 40% of GEFS members showing 6″ or more of snow, so pretty good odds considering we’re still a few days from this event.


A look at the minor snow event for tonight and Friday per simulated radar forecast ending 6 PM Friday — This looks worse than what will likely see in terms of snowfall, as there is a lot of dry air that will need to saturate before we start to see some snow.

Light snow is possible at times in the Twin Ports after Midnight tonight through Friday morning before ending Friday afternoon. Total snowfall accumulations <1″.


A widespread snow event is possible this weekend which may impact all of or at least parts of the Northland. Timing looks be from Saturday evening into Sunday, but some light snow may linger all the way through Monday morning.

The system which is expected to impact the Northern Plains and upper Midwest this weekend digs SE out of southwest Canada and across the upper Midwest on Sunday, reaching the Great Lakes on Monday.

Probabilities for exceeding warning criteria snow amounts Saturday night through Sunday night is currently highest near Lake Superior (red and yellow colors) with lower probabilities of warning criteria snow amounts across northern Minnesota (blue area on map).


High temps in the Northland will remain above normal on Friday and will be near normal to slightly above normal for Saturday and Sunday.
