Rain chances return to the Northland Friday and Saturday as will see another cold front move across the upper Midwest.

Currently it looks like northern Minnesota will have the best chance to get some rain Friday afternoon through Friday night, with chances for some rain increasing late Friday night through the day Saturday from eastern Minnesota into northwest Wisconsin.

The threat for strong to severe thunderstorms for late this week looks pretty low at this time due to only marginal amounts of instability.

Heavy rain is possible late this week especially on Saturday where there is a risk for flash flooding (yellow) from south-central Minnesota into north-central Wisconsin.

Thanks for reading!
