Sunday rain chances highest to the south; Wednesday soaker?

Fall color update for leaf-peepers

Saturday afternoon was gorgeous!

The Saturday high temp at Minneapolis-St. Paul International Airport was 52 degrees. That’s just two degrees shy of our average Oct. 23 high in the Twin Cities. Highs in the upper 40s to lower 50s were found throughout most of Minnesota and western Wisconsin on Saturday. We had light winds and plenty of sunshine.

Look for some changes on Sunday.

Sunday rain chances highest south

A low pressure system will track across northern Missouri on Sunday, spinning moisture northward. The steadiest rains are expected to fall in Iowa, northern Illinois and parts of southern Wisconsin Sunday and Sunday evening. Far southern Minnesota will see periods of showers Sunday and Sunday evening, especially along and south of I-90. It looks like scattered afternoon/evening showers could spread as far north as Marshall, New Ulm and the southern edge of Twin Cities metro area.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model model shows the potential rain pattern Sunday and Sunday evening:

Wednesday looks like the rainiest day of the coming work-week, with periods of rain across much of Minnesota and western Wisconsin.

The percentage of changeover to fall colors is between 75 percent and 100 percent in the medium-red shaded areas, including much of the Twin Cities metro area and portions of southeastern Minnesota.

Keep in mind that all deciduous trees are included in the fall color report, not just maples.
