*Here’s my snowfall accumulation forecast for Sunday into early Monday. Note: For Duluth and Superior I’m currently leaning closer to the 2″ mark rather than 4″. Highest amounts should remain south/east of the Iron Range. North Shore of Lake Superior could have even higher totals due to lake enhancement.
Winter Weather Advisory covers Southern Lake and Southern Cook County in NE Minnesota from Noon Sunday until 6 AM Monday.
Winter Weather Advisory for Ashland, Iron, Sawyer, and Price County in Northwest Wisconsin from 6 AM Sunday until 6 AM Monday.
Use caution if you have travel plans around the Northland on Sunday. Allow extra time to reach your destination.

Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin
Arctic air remains in place with high pressure of 1045mb centered to the southwest of the Northland late This Afternoon. Sunshine was abundant Today but high temperatures were only in the single digits below zero which is 20 to 30+ degrees colder than average for early December. Winds Today were out of the west or southwest at 5 to 15 mph. Late day wind chills were in the teens and 20s below zero.
Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Short Term Forecast – Confidence: High.
Tonight (December 7)
Mostly clear skies during the Evening will give way to partly to mostly cloudy conditions Overnight. Expect another bitterly cold night as low temperatures fall into the teens and 20s below zero with some minus 30s possible once again over Northern Minnesota. Winds will be out of the west or south at around 10 mph. Wind chills will range from 20 below to 40 below.
Sunday and Sunday Night (December 8)
Snow is possible over the Northland during this period.
A low pressure disturbance over the Central Rockies will move east/northeast through the Plains and into the Central/Eastern Great Lakes by early Monday Morning. This system looks like it will produce at least a little bit of snow over NE Minnesota and NW Wisconsin with snow beginning 1st in Southern parts of the area Sunday AM before spreading farther north/east Sunday Afternoon. Snow should then decrease from west to east late Sunday Night.
With so much cold air in place QPF amounts will be limited, but the cold air will also lead to high snow ratios which could range from 20:1 to possibly 30:1 during this event.
I do think most areas south/east of the Iron Range could get 2-4″ of fluffy snow by late Sunday Night while areas west/northwest of the Iron Range might get an inch. Note: Locally higher amounts are possible along the North Shore of Lake Superior thanks to southeast winds coming off the lake which may lead to some lake enhanced snowfall Sunday PM.
High temperatures Tomorrow will be in the single digits and teens with lows in the single digits below to around 10 above zero. South, east, or west winds are expected this period at 5 to 15 mph.
Extended Forecast – Confidence: High.
Monday through Wednesday (December 9-11)
Still looks very cold through this period. A weak system could bring a few snow showers/flurries to the Northland Monday Night/early Tuesday, otherwise this period looks generally dry. Highs will range from the single digits below to single digits above zero with lows Monday Night and Tuesday Night ranging from the single digits below to 20s below zero.
Long Range Forecast – Confidence: High.
Below average temperatures look like they will continue from the 12th-14th, may see some moderation occur between the 15th-17th with perhaps more seasonable temperatures for this time of year. Might see a few disturbances bring some more snow to the Northland at times from the 12th-17th.
