Some wet snow and mixed precip through Friday, winter weather advisory in effect for much of the Northland

  • Not expecting any major impacts from this system affecting northeast Minnesota and northwest Wisconsin tonight and Friday with generally light snowfall rates and patchy blowing snow.
  • Surface temps will remain on the mild side through Friday, so it’s possible that some of the precipitation will fall as light rain or drizzle at times especially closer to Lake Superior.
  • Northeast winds could gust to around 20-30 mph around Lake Superior tonight into Friday morning, with gusty winds also possible from east-central Minnesota into northwest Wisconsin.
  • How crazy is this weather pattern? There’s a blizzard warning in effect for parts of western/southern Minnesota tonight and Friday, meanwhile in northern Minnesota, International Falls and Hibbing had near record warmth today.

Low pressure over central Minnesota as of 3 PM Thursday will drop SE into eastern Iowa by Friday morning, then will see this low move or redevelop NE into lower Michigan by Friday evening.

A tight pressure gradient covered the Plains today between the low to the east and strong high pressure over the Northern Rockies, this has resulted in a very windy day from the Dakotas to Kansas.

A plume of moist air continues to pump NW into the upper Midwest today while drier air pushes SE out of the Dakotas.

…High Wind…

Strong northwest winds occurring today across the Northern and Central Plains with 850mb winds >50 knots! The strong winds associated with this storm won’t be affecting the Northland as they remain further to our west and south through Friday.

A fairly amplified weather pattern in place today with an upper level ridge (blue H on map) poking north into the western US with another ridge covering the eastern Great Lakes and adjacent portions of eastern Ontario. Upper level troughs (red L on map) were found across the Northern Plains and south of Alaska.
