A broad area of low pressure ~1006mb extended from north central Kansas to northern Iowa late this afternoon with arctic high pressure of 1036mb over Alberta Province. The low to our south has a good temperature gradient to work with with late afternoon temperatures ranging from around 40 degrees in central Iowa to 30 degrees in extreme southern Minnesota to the single digits below zero in extreme northern Minnesota, this temperature contrast has helped to produce some snow today, and there’s also been some weak banding in the snow thanks to some minor Frontogenesis which has been affecting mainly southern portions of the Northland.
Note: All in all the snow that fell today was on the light side with relatively small snowflakes resulting in lower accumulations than what was in the forecast for the immediate Duluth area. There’s been a few bursts of moderate snow with larger snowflakes especially over parts of northwest Wisconsin and adjacent areas of far eastern Minnesota, and this is where the greatest snow accumulations have occurred today (2″+) outside of the isolated 3″ report near Two Harbors. So in the end the greatest snow amounts ended up a little farther south of Duluth today compared to what model guidance was showing on Friday. Today’s snow event fits the trend we’ve seen with past snowfall events this winter, generally light snowfall amounts but just enough snow to mess up the roads and cause slippery driving conditions.
High temperatures today ranged from around zero in far northern Minnesota with lower teens in east central Minnesota and northwest Wisconsin.
Tonight: Light snow will continue this evening in northwest Wisconsin and eastern Minnesota but this snow will be ending from NW-SE. Lake effect snow showers could continue most of the night, however, along the South Shore in favored north wind areas. Otherwise the other weather story tonight and for the next few days will be the cold temperatures as arctic air returns. Lows tonight will be in the teens and 20s below with 30s below possible in far northern Minnesota while single digits below zero will be found over eastern portions of northwest Wisconsin. Note: Drive safely tonight as roads will continue to be snow covered and slippery in parts of the Northland.
Sunday and Monday: Generally dry and cold conditions as one high moves southeast out of the northern Plains, which will then be replaced by a new high on Monday as it builds southeast into the northern Rockies. Highs Sunday will be in the single digits below to single digits above zero, highs Monday will be in the single digits and teens above zero. Lows Sunday night and Monday night are expected to be in the single digits, teens and 20s below.
