Simulated Radar Forecast valid from 7 PM this evening to 1 AM Saturday — An area of showers could affect portions of north-central Minnesota tonight, possibly moving through northeast Minnesota and far northwest Wisconsin Friday morning. A few stray showers could linger Friday afternoon/night mainly over northern Minnesota. Note: I don’t think will get much rain here in Duluth/Superior, but can’t rule out a passing shower or a few sprinkles Friday morning.

High pressure remained over the Northland today which gave us lots of sunshine, although there has been some passing mid/high level clouds moving through some parts of the area this afternoon. Highs today were in the mid 60s to around 70 degrees with slightly higher dew points compared to 24 hours ago with late afternoon dew points generally in the 40s.
An area of warm air advection and higher instability has moved NE into the northern Plains today, and this has caused an area of thunderstorms which have been severe at times over parts of northern North Dakota this afternoon. These storms should weaken quite a bit as they move farther east tonight, but some rain showers and isolated thunder are possible tonight in parts of northern Minnesota. Partly to mostly cloudy skies for tonight with lows tonight ranging from the lower 40s to middle 50s so not as chilly as it was Thursday morning.
A few showers mainly in northern Minnesota, dry elsewhere. Highs Friday in the mid 60s to low 70s under partly to mostly cloudy skies.
Note: A cold front will move into far northern Minnesota tonight and should remain over northern Minnesota through Friday before washing out by Saturday, meanwhile high pressure will move east out of Manitoba Province through the weekend — An easterly wind is expected for the next few days due to the area of high pressure over central Canada.
Looks mainly dry in our area Saturday and Sunday with highs in the lower 60s to lower 70s Saturday, and from the upper 60s to middle 70s for Sunday. There could be a few showers or thunderstorms over parts of the Northland early next week as a frontal boundary moves through the area, but this doesn’t look like a real big deal in terms of heavy rainfall or severe weather potential right now.
