Duluth Harbor: 66 degrees at 7 AM; 39 degrees at 3 PM today
Superior: 66 degrees at 7 AM; 46 degrees at 10 AM; 39 degrees at 3 PM today
Temperatures in our area are running 30 to around 40 degrees colder at 5 PM today compared to 5 PM Monday, this is thanks to widespread clouds, some rain and a strong lake wind. Late afternoon temperatures were only in the upper 30s and 40s over most of northeast Minnesota and northwest Wisconsin.
Light to moderate rain is expected to continue over portions of the Northland through Wednesday as low pressure tracks from eastern South Dakota to east central Wisconsin. An isolated thunderstorm is also possible mainly over far southern portions of the area where some weak elevated instability will be present.
Lows tonight will be in the 30s and 40s with highs Wednesday mainly in the 50s but some western locations could climb into the 60s (International Falls, Bigfork and Brainerd areas)
Thursday looks mainly dry with highs in the upper 40s to mid 50s. There is another system for late week, but this one looks like it will be too far south of our area to give us much rain for Friday and Saturday.
Warming trend ahead for late this weekend into early next week — Should have highs in the 60s and 70s over most of the Northland from Sunday through Tuesday (13th-15th)
