The second weekend of September brings a few shower chances. Most of the hours this weekend will be dry, but it will be a pick-your-spot forecast for outdoor activities this weekend.

A cold front crossing Minnesota Saturday brings scattered showers and a few thundershowers. The National Oceanic and Atmospheric Administration’s latest NAM 3 km model shows showers favoring western Minnesota in the morning hours on Saturday.

Cells may grow in coverage Saturday afternoon into the evening across eastern Minnesota including the Twin Cities area. The forecast model loop at the top of this post runs between 9 a.m. Saturday and 1 a.m. Sunday.

Overall rainfall totals look patchy and light on Saturday.

The map below shows the European Centre for Medium-Range Weather Forecasts model rainfall output. It favors a few tenths of an inch in most locations, with a few pockets of locally heavier rainfall.
