Cool, overcast and wet the next few days with some snow also possible at times

Precipitation totals of an inch or more are likely by Tuesday afternoon across northern and northeastern Minnesota with half to one inch totals for northwest Wisconsin, while lesser amounts of precipitation of around a quarter of an inch are expected toward the Brainerd Lakes area.

Note: The last time Duluth had a day with some sunshine was last Monday, April 5th, so yes it’s been a while, and it looks like will be waiting a while longer before we have any chance at seeing the sun again, maybe by Tuesday or Wednesday will see some sun at times, otherwise not until later this week the way it looks now.


Rain has been slowly but steadily been pushing farther west-northwest across the Northland today, and as of 5:30 PM Sunday the leading edge of the rain extended along a line from just east of International Falls to Hinckley.

  • Rain this evening will transition to a rain/snow mix across parts of northern Minnesota (NW of Duluth) after Midnight tonight, with this rain/snow mix possibly changing over to all snow for a few hours Monday morning before changing back over to rain or a mix Monday afternoon.
  • Areas of rain or snow continues across the Northland Monday night and Tuesday.

Note: A steady rain in Duluth and Superior tonight will diminish to more scattered rains by Monday afternoon, meaning will probably have some dry times mixed in on Monday. More showers of rain and or snow are then expected in the Twin Ports Monday night and Tuesday, but no snow accumulation is expected.

Boundary layer temps and snowfall rates will play important roles on how much snow actually accumulates in northern Minnesota through Tuesday morning, it is April after all. A stronger sun angle this time of year and warmer ground temperatures could also play roles in keeping snow amounts on the minimal side, time will tell.

No doubt the temperatures aloft will cool sufficiently for snow to fall Monday and Tuesday, but whether or not the snow falls to the surface will be depend on temperatures near the surface which will likely be in the mid to upper 30s during the day, and around 30 at night, so a scenario where we see a couple times where precip switches from rain to snow and then back to snow to rain is certainly possible in parts of the Northland for Monday and Tuesday.


A complex low pressure system will be affecting our weather over the next few days.

One low to our southeast will interact with another low approaching from the Northern Plains to produce chances for rain and snow along with mostly cloudy skies through Tuesday.

Here are the two systems (white outlined areas) which will keep the weather pretty gloomy in our area the next few days, while some moisture from the Atlantic (green outlined area) pushes west into the Great Lakes region.
