Rain continues at times through Friday night; more rain chances next week (maybe some snow)

There won’t be a lot of change in our weather over the next few days as a slow moving low pressure system continues to lift slowly N/NE into the upper Midwest before exiting to the NE by early Saturday.

An easterly wind coming off Lake Superior will keep temps on the cool side near Lake Superior while also producing areas of fog (locally dense) along with some drizzle at least through Thursday night.

Expect occasional rain with some dry hours mixed in across the entire Northland from tonight through Friday. Note: Isolated thunderstorms are also possible tonight from eastern Minnesota into northwest Wisconsin.

An additional 0.50 to 1.50″ of rain is likely across the Northland thru Friday evening with locally higher amounts possible. Note: Widespread flooding is unlikely due to this being more of a light to moderate rainfall event over a span of a few days, but localized flooding and or ponding of water is certainly possible in parts of the Northland tonight and Thursday.

18z HRRR model simulated radar forecast thru 1 PM Friday.

The rain won’t be continuous through Friday as there will be breaks in the rain from time to time.

Slow moving mid/upper level low pressure systems will be the story through next week, and the one that could move through the upper Midwest next week may have enough cold air with it to produce a mix of rain and snow across parts of the Northland. Stay tuned.
