Snow and patchy freezing drizzle this evening with rising temperatures; Arctic air arrives Friday with gusty winds and lingering flurries/snow showers

5:13 PM Thursday, February 10, 2022

  • Snow (heavy at times) into early this evening, but the snow will diminish from NW-SE through the evening hours.
  • A brief period of freezing drizzle remains possible in parts of the Northland through late this evening.
  • Occasional snow showers and flurries will likely occur at times overnight through the day on Friday.
  • Lake effect snow showers develop on Friday along the South Shore of Lake Superior in northwest Wisconsin, and there is also a chance we see a gravity wave setup over western Lake Superior which may lead to an area of snow for a few hours Friday afternoon-early Friday evening over portions of Douglas County into northern Bayfield County in northwest Wisconsin, and possibly extending southwest into southeast Carlton and northeast Pine County in Minnesota.

For Duluth — Snow into this evening but the snow is expected to taper off between 7-9 PM tonight, but some snow showers and flurries may continue at times overnight and right through the day on Friday, but the bulk of the accumulating snow occurs through this evening. Total snowfall accumulations of 2 to 4 inches are possible by late this evening. Note: A period of freezing drizzle is possible mid to late this evening.

Overall, we’re looking at a general 2-to-4-inch snowfall in northeast Minnesota and northwest Wisconsin through late this evening, but a few isolated totals to 5 inches can’t be ruled out, but this system is moving through so quickly that it may even be difficult to get much more than 2 or 3 inches of snow out of this system.

Higher snow totals remain possible in the Arrowhead (along the North Shore) due to lake enhanced snow plus the system snow this evening.

Snow continues to fall in northeast Minnesota late this afternoon, but in the warmer air there are reports of some drizzle and light rain in parts of western and southwest Minnesota late this afternoon.

Clipper impacting the Northland today is a potent one as it has a lot of upper-level support to produce a brief period of moderate to heavy snowfall rates (lasting roughly 1 to 3 hours in any given location)

Strong divergence occurring in the Northland this afternoon ahead of a strong jet streak of up to 140 knots.

Strong warm air advection (red) will continue this evening but will be replaced by strong cold air advection (blue) on Friday.

Low pressure moves ESE out of northwest Minnesota early this evening to south of Marquette, MI by around daybreak on Friday.

A variety of weather alerts are in effect due to a strong clipper which is impacting the Northern Plains and upper Midwest tonight and Friday.

The blizzard warning to our west is mostly due to blowing snow, which is forecast to develop later this evening, and then continuing till around mid-morning on Friday.

Definitely have seen some convective elements in the snowfall across northern Minnesota this afternoon as evident by the lumpier appearance in the clouds per visible satellite imagery.

Steep mid-level lapse rates of >7.0 C/km also support the development of heavy snow bursts downstream across the Northland late this afternoon into early this evening.

Near freezing line which was over western Minnesota (white line on map) at 2 PM today will be moving farther east through early Friday morning.

Temperatures are expected to warm to between 30 to 33 degrees in Duluth from around 10 PM tonight to 2 AM Friday, this will be followed by falling temperatures during the day Friday as another round of arctic air approaches from the north.

Windy weather is expected in the Northland through Friday.

Breezy southerly winds early this evening will shift to the northwest by late tonight, and those northwest to north winds will continue through Friday evening. Wind gusts of 20 to 30 mph to possibly as high as 45 mph will occur across the Northland through Friday afternoon.

Frigid temperatures return to the Northland Friday night with lows in the teens to 20s below zero, with a few 30s below possible in the typical cold spots. Wind chill headlines will probably be needed as well for Friday night.

Arctic air remains over the Northland right through Sunday with more subzero lows likely for Saturday night.
