A low-pressure system, along with its warm and cold fronts, will move across the Northland on Saturday, bringing a chance of scattered rain showers. While overall rainfall is expected to be light, and some areas may remain dry, a few showers are still possible throughout the day.
August 4th marked the last time Duluth received at least a quarter inch of rain (0.26″), which was over a week ago. The likelihood of receiving at least a quarter inch of rain on Saturday currently appears quite low.

The larger concern is the precipitation deficit dating back to 2024, with Duluth currently over 15 inches below normal (-15.64″). Significant relief would likely require an unusually heavy rainfall event.
